TDA2EG: 2D Surround View Calibration Issue

Part Number: TDA2EG

Hi

     I am studying how to calibrate the 2D Surround View.

    According to the "VisionSDK_UserGuide_2D_SurroundView_Demo.pdf":

    1 first, i should use the fisheye distortion center tool to get the center position of 4 input frame;

    2 then, i should use the calibration tool to get the initial perspective matrices;

    3 But, how about GAlignLUT table? Except for contact FAE, is there any other ways that i can update the GAlignLUT table by myself?

    By the way, could you explain more about the information of GAlignLUT table?

    for example, distortion centers describe the 4 input frame's distortion centers from vertical to horizontal one by one; and  initial perspective matrices describe 4 camera's matrix (3*3) one by one.

    So what the physical description of  GAlignLUT table' information? It is a real huge array...

Thanks

          I have solved this problem by my self. The solution is that use the "2d_calibration_tool\calibration_tool\calibration_tool.exe" to generate the new GAlignLUT table, then update the related C files of surround view.

          But, i still hope that someone can explain about GAlignLUT table in more detail, thank you ~

    Thanks
