    NATIVE 3D VERSUS 2D TO 3D CONVERSION: PROS AND CONS

    There isn’t a child who isn’t fascinated by Pixar’s Toy Story series. Though mere toys, Woody and Buzz Lightyear, even today, do not fail to capture the imagination of every tiny tot. 2D to 3D stereo conversion gave a whole new dimension to Disney’s first entirely computer animated feature, Toy Story (1995) and its sequel (1999).

    2D to 3D video conversion (also called 2D to stereo 3D conversion and stereo conversion) is the process of transforming 2D (“flat”) film to 3D form, which in almost all cases is stereo, so it is the process of creating imagery for each eye from one 2D image. (Wikipedia)

    The realm of 3D incorporates the third dimension of depth, which can be perceived by the human vision in the form of binocular disparity. The positioning of the human eyes affects the way in which they perceive different views of the real world. A native 3D production takes advantage of this phenomenon, by which two cameras are used, positioned next to each other, shooting at the same time to mimic each human eye. Those movies not shot in this manner cannot be made into a 3D film, which is where 2D to 3D stereo conversion emerges as savior.

    The extreme advances in the field of computer animation enable a second camera view to be added, thereby giving depth and volume to each and every 2D frame. The position of the “second (virtual) camera” with respect to the first determines the degree of 3D, namely in front of screen (when an object seems to be in with the viewer), at screen (regular 2D image) and behind screen (when the objects seems to be at a distance away from the screen).

    Filming in native 3D involves a large number of variables and taking into account the various parameters, this could involve incredibly expensive, bulky and complicated equipment and hardware. With hardware come human errors, which includes disparity and distortion of imagery shot by the left and right cameras, complex action sequences which can only be shot with 2D monocular cameras, color shift, etc., among others. Stereo post production is another major hiatus when compared to stereo conversion, in addition to being more expensive and time consuming.

    On the other hand, in a stereo conversion, stereographers can perform as many digital “retakes” as required to perfect every angle and depth in order to maximize the quality of each sequence in a movie. “I get to set the parameters on a shot-by-shot basis”, says Bob Whitehill, stereoscopic supervisor at Pixar Animation Studios, “With cameras that are computer code and not physical objects, the 3D effect can be absolutely perfect, with no visual incongruity between what the left and right eyes see.” (www.tested.com)

    With the growing need for high quality stereoscopic images, the future of 2D to 3D stereo conversion looms large.

    BPM Approach to BPO

    In the early part of this millennium, organizations around the world started looking at outsourcing their business processes to cut costs and become more competitive. This is how the Business Process Outsourcing (BPO) industry was founded, primarily to provide low-cost options for business process delivery.

    Over the years, BPO service providers have developed a strong understanding of their clients’ businesses and have steadily moved up the value chain in terms of the services offered. Far from just being providers of low-cost back-end services, these companies have now become strategic partners for their clients and directly impact client profitability on a global level. Offerings such as end-to-end actuarial services support for the insurance industry; predictive analytics models for managing demands and forecasts in the retail / CPG industry; or managing multi-channel customer interactions as well as revenue generation at the contact center for the travel industry, are examples of the transformation shift from BPO to Business Process Management(BPM).

    This shift signifies increased maturity of an industry that manages complex processes and truly understands the client’s industry, client needs for regulatory compliance, risk mitigation and the impact and demands of globalization.

    BPM also reflects the move from a business model focused on being input-based to outcome-driven, where the BPM provider takes responsibility for the client’s business results. In a sense, the transformation from BPO to BPM reflects the journey of the industry from the back-office to the client’s boardroom.

    For enterprises looking at outsourcing as a means of transforming their business processes, achieving cost efficiencies is of top-most priority. However, intelligent organizations are now focusing on going beyond cost-saving mechanisms and looking at achieving greater flexibility to scale and support their global operations.

    The BPM providers that will succeed will be those that stay abreast of future trends and partner with the right technology and develop processes to deliver the right solution. This is about branching out of the back-office and stepping up to the board room to make a difference to our clients top and bottom line – not just costs.

    Our services at SBL include research and analysis, finance and accounting, document management, and claims processing.

    Parcel mapping through GIS technique

    New Image

    A digital record of land parcels or plots is a necessity of modern day administration of any country. In general these data is available in old paper maps and cloth mounted maps which are poorly maintained. In modern era, with every aspect of life is going digital, it is imperative to get the parcel/plot boundaries also in digital form for effective administration and as part of the e-governance initiatives. Land administration will be much easier with parcel boundaries in digital parcel map or Cadastral map. The Cadastral map is one of the basic registers that administration at village, town, city and country can have.

    SBL Geospatial Services division is having in-house experience and expertise in executing such GIS services. Geographic Information System (GIS) is an appropriate tool used in mapping parcel boundaries. First step in such mapping process is geo-referencing of the parcel maps after converting the paper maps into raster format by scanning method. The ground control points required to register scanned images to the ground is possible through field surveying, from other georeferenced maps, from open source data. Geo-referenced parcel map can be used digitize the parcel boundaries through heads-up digitization. The mapped objects can be point, line or polygon. Added advantage of parcel mapping in this way is that, one can incorporate any number of attributes to the digitized parcel boundaries. This will explicitly give ownership details, history of ownership, change details of the properties and any other relevant information deemed fit for the purpose.

    New Image2

    The digital parcel map is the vital component of any cadastral system and is used for legal, administrative and economic decision making and an irrefutable input for planning and development. One of the most important and basic benefit is that individuals can easily come to know about the area of land under their ownership and other details of their own property. This will help government directly by getting right amount of tax without any evasion due to poor record maintenance and difficult retrieval process of the same. It will greatly help urban development departments by assessing accurately parcels and properties affected by any developmental program and decision making will be much easier as we know the impact beforehand. Municipality planning will also be much easier with a digital parcel map, as the department is having accurate details of properties under its jurisdiction.

    Most suitable GIS software, ArcGIS is nominated for carrying out the parcel mapping work. Besides digitizing, attribute assignment and management and geo database management, topology building and checks will be very easy in this software platform. Parcel mapping services also include mosaicking or seamless joining of adjacent maps so that village, taluk or district level data can be viewed and analyzed simultaneously. This will be highly helpful for the decision makers. Unlike paper maps and cloth mounted maps, digital parcel will be easy to analyze for area calculations and other statistics. The final results of the parcel maps can be represented in the form of ready to print maps by applying cartography techniques to the mapping process. Standard mapping symbology can be used to demote boundaries of parcels and other details thus mapped.

    The paper or cloth parcel map was observed as a static, plain view of preselected areas, available at fixed scales, but due to the advances of the geospatial technology, it is now progressing into a dynamic, recurrently updated network of interconnected databases with large amounts of geographically referenced information linked to a comprehensive central digital parcel database.

    LiDAR DATA PROCESSING AND ASSET MANAGEMENT

    LiDAR(Light Detection And Ranging):A form of representation of 3D surfaces, Point cloud data, are usually produced by aerial or terrestrial laser scanning, also known as Light Detection and Ranging (LiDAR). The data is produced as sets of very dense (x, y, z) points or in a more common, binary format called LAS that may include values of multiple returns and point intensities. Many leading GIS processing software’s now accommodate and supports basic and advanced LiDAR data processing and analysis. LiDAR is emerging as one of the cost-effective and accurate data capture system to manage large assets such as Railway stations and other public/private infrastructures.
    SBL GIS Services division has been in the forefront of processing LiDAR services for some time now. Our LiDAR data processing services has been entrusted with prestigious and complex Infrastructure modelling projects across many geographies. One such example is demonstrated in the picture given below.

    Picture1
    Fig-1: All visible data captured as vector data with the help of Terrestrial LiDAR scanner point cloud data related to this project and attributed to their respective code. The above view is illustration of the output.

    The Science behind LiDAR Working
    LiDAR working is quite simple and it works on the principle of Light – speed and time taken to reflect the same from a surface. The distance is calculated from the difference between the time when a beam of light hits a surface and measure the time it takes to return to its source. Light travels very fast – about 300,000 kilometers per second, or 0.3 meters per nanosecond so we feel the instantaneous result when a light is turned on. The paraphernalia required to measure this needs to function extremely fast. Only with the advancements in modern computing technology has this has become possible.
    Distance = (Speed of Light x Time of Flight) / 2

    USES OF LiDAR MAPPING.
    One of the main focus of LiDAR services in the Urban Infrastructure Mapping.

    Urban Infrastructure Planning  
    Urban Planning or City development is the science of land use planning which considers several aspects of the as-built data and social environments of the area of interest. LiDAR Mapping is a moderately new technology for obtaining Digital Surface Models (DSMs) and Digital Building Models. This data, when combined with orthorectified images, can create highly detailed Surface Models and eventually 3D City Models.
    Wayside assets include tarmacs, streetlights, signs, advertisement boards, traffic signals and street furniture. A thorough understanding of all the assets, what they are and where each asset is located, is crucial to the development of an asset portfolio.
    An accurate record of all assets along the transportation network is vital to asset management, to plan a maintenance schedule and budget costs. A bigger challenge than developing the asset database is keeping it up to date and this is where the cost-effective, accurate LiDAR Mapping will come into play.

    UAV DATA PROCESSING FIELDS OF APPLICATION

    UAV data processing

    UAV data processing


    This write-up intends to present birds eye view of fully automated and accurate mapping solutions based on ultra-light UAV imagery. We showcase interesting observations in the field of UAV mapping, the steps to analyze the accuracy of the automated processing on several datasets. The software used to process is one of the leading and evolving software in the UAV data processing domain.
    The accuracy highly depends on the ground resolution (GSD) of the input imagery. When chosen appropriately this mapping solution can compete with traditional mapping solutions that capture fewer high-resolution images from airplanes and that rely on highly accurate orientation and positioning sensors on board. Due to the advancement of computing practices and processing prowess of computers and careful integration with recent computer vision techniques, the result is robust and fully automatic and can deal with inaccurate position and orientation information which are typically problematic with traditional techniques.
    SBL’s geospatial team is one of the first in the region to process such images. Processing of UAV images has its own challenges. SBL used to receive post-processed UAV images along with IMU and GCPs as input. Aerial Triangulation is the first step performed. During this stage Ground Control Point (GCP) and Actual Check Point (ACP) reports has been generated. This is an iterative step till we get desired accuracy. The following will explain in brief some of the critical steps in the processing of UAV data.

    1. The software examines for matching points by analyzing all images. The software used here an improved version of the binary descriptors, which are very powerful to match image points quickly and accurately.
    2. Those matching points as well as estimated values of the image position and orientation provided by the UAV autopilot are used in a bundle block adjustment to reconstruct the exact position and orientation of the camera for every acquired image.
    3. Based on this re-establishment the matching points are corroborated and their 3D coordinates calculated. The geo-reference system is WGS84, in this case, based on GPS measurements from the UAV autopilot during the flight.
    4. Those 3D points are interpolated to form a triangulated irregular network in order to obtain a DEM. At this stage, construction of a dense 3D model increases the spatial resolution of the triangulated data.
    5. This DEM is used to project every image pixel and to calculate the geo-referenced ortho-mosaic. The ortho image will be devoid of positional and terrain displacement inaccuracies.
    6. Picture1
      One of the major application for which UAV images used are for agriculture. UAV images are ideal for small size farms. Plant counts such as corn counting will give an idea of yield from those plants. Plant health monitoring, differentiating species of agricultural farms/plants and plantation estimation are the major task performed for agriculture. Growth stages of the farms can also be monitored using ortho images acquired through UAV process. UAV image processing is also helpful for the site selection for solar farms.
      In case of forestry, UAV images are very helpful in species identification. SBL’s interpreters have identified forest species and enabled the client to map forest land parcels. It is a tool to monitor de-forestation as well as afforestation. Golf courses are another field where UAV data sets are highly useful. Golf course features can be mapped with their actual heights through this process.
      Mining industry is the most benefitted in the usage of UAV technological advancement. As most of the mines are spread over small areas, UAV data acquiring and processing is very cost effective. Along with other data processing, SBL has got the expertise in generating contours and mining related features to very minute levels of detail.
