(WARNING: Hi, I'm sorry that this project is tuned for course demo, not for real world applications !!! If we had two calibrated cameras that were pointing the same direction, with some distance between the cameras in a purely horizontal sense, we can actually find interesting features in each pair of images and calculate where that point is in space with some simple geometry. A general framework for map-based visual localization. Visual Inertial Odometry (VIO) is a computer vision technique used for estimating the 3D pose (local position and orientation) and velocity of a moving vehicle relative to a local starting position. Over the years, visual odometry has evolved from using stereo images to monocular imaging and now . And it outperforms in some sequences by accuracy without additional traing about KITTI dataset.
