Hi, thanks for your sharing project. Now i have two questions. 1 What is the size value of one chessboard block. I did not find any info in the code of project. 2 Could i change the chessboard corner number. 3 The final output of depth map is always flashing when i run the original version code of your project. So the output value of one pixel when click the mouse varied too much while the mouse did not move any. Thanks for your help. @freduhr @LearnTechWithUs @UndecidedBoy @karan2808
