What do you get

2D 3D Capturing is capture contextual information related a 2D 3D scene of the surrounding so that the data can be used to provided to or as services. Location information, lighting information, device orientation, heading direction are the necessary contextual information and based on the service these other information available to the browser can be used. Air pressure, time the image is taken are some of the available important meta data can also be used as "Tagging content". Tagging can be similar to the contemparary geo tagging but highly dependent on the image format (JPEG, PNG, ogg, wmv, ect....). Exif extension method can be used if the format used is JPEG and for image formats such as PNG another method can be used. Format of the image in image capture depends on the usage scenario. For example in a situation where image processing is minimal JPEG compresssion can be better over PNG lossless images.

Why to get it

Photos taken from devices combined with the meta data shown as Tag are transferred to the 2D3D capture server. 2D 3D capture server API then can be used to dig up image based on time, location for use of other applications where 2D or 3D visual information is required. In the use case described here 3D scene builder can be a part of other GEs such as POI. Another use case is, using tagged images published by other services or devices such as Flickr to build a 3d model of the current location so that a person such as lost tourist could find his way. Elaborating on the "Tag" and its content, images are geo-tagged in order to improve the user experience in social networks images. 3D information can be used similarly to improve the quality of the user experience and meta data that can be associated with a model improves number of use cases 3d modelling can be used. Most importantly information such as orientation of the device at the moment which the photo is taken can be used to improve the accuracy and it also helps to filter out less useful images from the useful once. In a hypothetical security situation where two images taken from known locations by two security cameras at the same time could be useful in identifying a criminal who happened to be at that location. By using meta data such as lighting conditions the accuracy of the 3d model of the criminal can be improved and will avoid innocent being targeted.
