Find how many cameras are seeing a point

Post by aweinstein »

Hi:

I want to find how many cameras are seeing a point, through the API. In the calibration tool, if I select the "Show camera rays" option, I can get that information, but I haven't find the way to do it through the API.

Hi Alejandro,

I've been making more information accessible via the API. The camera rays are not currently available, but if you're requesting that information, I will add it to the API and get you something very quickly.

That will be great. The reason I want to know the number of cameras seeing a point, is that I think that the accuracy of the measurements is not too good if the point is capture from less than three cameras. Thus, from my program, I am not sure if I am getting a good measurement or not. Is my reasoning OK?

Your reasoning is correct. The more cameras you have looking at a point...6, 8, 10, etc. the error just keeps getting better.
