Generate camera parameters in HalconDotNet

In Halcon one can: gen_cam_par_area_scan_polynomial (0.008, 0, 0, 0, 0, 0, 5.2e-006, 5.2e-006, 640, 512, 1280, 1024, CameraParam) to get the required camera parameters.

In HalconDotNet (C#) this function does not exist, how can one generate camera parameters in HalconDotNet?

Solution

  • If you look inside function gen_cam_par_area_scan_polynomial (0.008, 0, 0, 0, 0, 0, 5.2e-006, 5.2e-006, 640, 512, 1280, 1024, CameraParam) in HDevelop you can see that it creates tuple with input parameters that you provide and returns it

    CameraParam := ['area_scan_polynomial',Focus,K1,K2,K3,P1,P2,Sx,Sy,Cx,Cy,ImageWidth,ImageHeight]
return ()

    so in C# you can do

    HTuple cameraParam = new HTuple("area_scan_polynomial", 0.008, 0, 0, 0, 0, 0, 5.2e-006, 5.2e-006, 640, 512, 1280, 1024);
