If you remember what we said in the lesson dedicated to Geometry, linear transformations (in other words any combination of any of these three operators) can be represented by a 4x4 matrix. As you know, objects in 3D can be transformed using any of the three following operators: translation, rotation and scale. Now, let's consider the camera but before we do so, let's talk about a concept in CG which is very important.
Points are defined in world space (figure 4).Ĥx4 Matrix Visualized as a Cartesian Coordinate System The coordinate system has an origin, which is called the world origin and the coordinates of any point defined in that space, are defined with respect to that origin (the point whose coordinates are ).
When a point is first defined in the scene, we say its coordinates are defined in world space: the coordinates of this point are defined with respect to a global or world Cartesian coordinate system. If you are interested to learn how it is done in ray-tracing, check the lesson Rays and Camera.

You can download both the Matlab implementation of the algorithm and the training data.The technique we will describe in this lesson is specific to the rasterisation algorithm (the rendering technique used by GPUs to produce images of 3D scene). You can see the algorithm in action in the following video:įrom video to depth map to 3D stereo images You can see the arrangement used in the photo above. The method was trained and tested using a set of videos that were gathered in stereo using a Kinect to measure depth where possible. If the input is a video then motion flow is used to improve the depth estimates - basically pixels that are in motion have to be in front of background pixels. A label based smoothing procedure is then used to improve the depth estimates. The matched object is assumed to be at the same depth as the library object. It then estimates warping functions, which indicate how the object is different in the target photo.

The new software does the job by keeping a database of objects with known depths that it can recognize in the photo. Single frames converted to depth maps - darker is closer However, try looking at a scene with one eye closed you will still be able to judge distances and even more impressive, you can judge distances in a single photo. After all, we have two eyes to be able to judge depth. You might at first think that all of this is an impossible task because you need stereo vision and hence a pair of stereo photos to work out depth.
Once you have a depth map you can apply it to the single image and create a stereo pair which can be viewed as a stereoscopic image. The algorithm attempts to construct a depth map of the sort the Kinect creates but without using a Kinect. This is all about taking a simple 2D image and working out how far away from you each of the objects in it are.

This time it's a library of code that converts a 2D video or still image into a 3D depth image. Microsoft Research has been hard at work doing impossible things again.
