Web24 de mar. de 2024 · Code. Issues. Pull requests. My goal is to come up with a simple and a basic model of an obstacle avoiding bot with the best possible algorithm to detect and avoid an obstacle using only One Ultrasonic Sensor module (HCSR04) and 2 wheels. The project is still into development to find even better an algorithm to achieve the same task.

Web6 de mar. de 2024 · The API supports all the 3 calibration patterns supported by opencv namely: Chessboards, Asymmetric circular grids and Symmetric circular grids. The API by default runs on 4 threads for speedup. The speed-up may not be marginal in the case of chessboard calibration because in most cases the bottle neck will be a single … Web5 de jan. de 2006 · Automatic: The detection of grid features is fully automatic. No clicking of corner points by the user (as in the popular camera calibration toolbox [1]) or parameter tuning is required. Robust: The grid detector is robust to partial occlusion, and works even when 30% of the grid is occluded (unlike OpenCV [2]).
