TDA4VM: Vision apps--3D Surround Vision Calibration Tool

Part Number: TDA4VM

Hi,

When I use 3D Surround Vision Calibration Tool to the fourth step of Camera Poses Estimation, after I finish Click pattern corners according to the steps, the whole interface turns grey after clicking confirm and can not be executed, may I ask what is the problem? What should I do to solve this problem? I tried to use SDK08.04 and 09.02 versions of the tool, but the same problem occurs.
