Study of stereo photogrammetry implementation in Matlab using disparity map and feature triangulation to reconstruct the scene and Structure from Motion to estimate the camera pose In this repository, 8-point algorithm is used to find the fundamental matrix based on SVD. However, the depth map I receive is not intuitive, as ideally the object in white should be in black and the background around it should be in white. Now I want to create a Kinect-like depth map for which I need to map the depth image to the original image (e. The accelerator is available as an RTL description using VHDL, which is fully parametrizable and synthetizable for FPGA or ASIC 3 I have calibrated and stereo rectified images in MATLAB using Caltech's toolbox. m contains three examples with Tsukuba, Middlebury, and KITTI stereo datasets.
