Summary of Weekly Meeting - (16)

I. Expected work and results before next Meeting:

   - Accomplish "2D-ImgPlane-Coordinate backTo 3D-world-Coordinate" process (...base on "Ray_Tracing" technique)

   - Showing the known points as well as testing points at the corresponding position in the Kinect 2D image (...i.e., 3D-world-coordinate to 2D-projection-coordinate related Kinect)

   - Do "Feature extraction" process, and use these features to substitute current points which are chosen manually (...i.e., the crosses located on a chessboard)


II. Draft codes:

    - Output the projection coordinates and world coordinate information of each pixels from OpenNI2 (...C++ part)

 
    - Save the Kinect outputs, including projection coordinates & world coordinates, of each pixels to be a mat-file.

    - Automatically find the corresponding position in the world coordinate to the known a 2D point.

 
    - Check the part of "Transform from 3D-world -> 3D-Webcam"    

    - Check the part of "3D-Webcam-picture -> Transform from 3D-world"

    - Check the part of "2D-Webcam-picture -> 3D-Webcam"

      * "Xc_inv_show" is the original result after the transition, but it's just a "unit", this needs to press the "z_var"

      * "z_var" is as a scaling factor which points out where will be the hitting position of the first point = (0.12235, -0.066628, 1))

    - Make a draft of "Ray_Tracing" and think about how to check every "Z-coordinate" brightly without searching exhaustly.
