OpenCV: Camera Calibration and 3D Reconstruction

Web29 de jan. de 2024 · I am currently working on an application that should triangulate points in 3d space with three cameras. The cameras are rotated 120° to each other with a pitch of 60° downwards. I used calibrateCamera to get the intrinsic and extrinsic camera parameters and that is working fine. I found two triangulation methods in the opencv documentation. Web19 de jan. de 2015 · On Line 28 we initialize our known KNOWN_DISTANCE from the camera to our object to be 24 inches. And on Line 32 we initialize the KNOWN_WIDTH of the object to be 11 inches (i.e. a standard 8.5 x 11 inch piece of paper laid out horizontally). The next step is important: it’s our simple calibration step. shrubbery campsite rousdon

The general idea is to form a mesh where each triangle's three points lie on the edge of a circle that doesn't contain any other point. This means given any two adjacent triangle's (quadrilateral) the sum of the angles opposite the dividing line are less than 180 degrees.
