Hi,
I am very new to LabVIEW (in fact to any coding at all) and helping my adviser to get the 3D coordinates of a few reflective markers using two cameras. I am able to read the marker coordinates (x, y) from two cameras simultaneously by processing the data in real-time using codes generated from vision assistant. However, we want to get the depth position by triangulating the markers. I have seen stereo vision doing something similar to this, but I think the stereo vision may not work with our calibration frame (markers) and we don’t need the whole depth image, but only the maker’s z coordinates. I also want to use Region of Interest to mask out other regions that are creating reflections. However, I am not sure if triangulation would work if we select region of interest (as the origin of the camera coordinates would change after selecting ROI). I saw this link http://kwon3d.com/theory/dlt/dlt.html#3d where they used DLT (direct linear transformation) method, but it is too much to code from the beginning. Is there a subVI in LabVIEW or some sort of prewritten code that can be customized? Can anyone please give me some advice on how to solve this problem?
