Recently in deep study close shot photogrammetry, but encountered some problems, for calculating program not to come out, want to ask everybody a great god,
I wrote the space resection and with camera calibration parameters space resection procedure, using its measured data (D3400 nikon camera), but the solution is not to come out, want to know which step was wrong?
I here have some questions: 1 the focal length of the camera is not from the Lord, then when I iterate calculation, the initial value into at first sight, I'm afraid to the initial values are not suitable, the result not convergence,
2 close shot photogrammetry should not consider scale, I understood the scale in the close shot photogrammetry should be 1, but really have no effect on the camera lens magnification?
3 camera sensor, size I query is to use the Internet, but only tell is about 15.6 mm wide, how to find the exact value,
Also please the great god,
