This algorithm uses images acquired from cameras and other image sensors. Visual SLAM can use simple cameras (such as wide-angle and spherical cameras), compound eye cameras (stereo and multi-cameras), and RGB-D cameras (depth and ToF cameras). This algorithm measures pictures and allows to fabricate a guide and confine the vehicle continuously. Visual SLAM algorithms also permit the vehicle to map out non-specified environments. This map data is used to bring out performance such as path planning and obstacle avoidance. Intensive testing of four different extractors- SIFT, SURF, SHI-TOMASI, and ORB-was undertaken, to determine the best use for indoor/outdoor environments. The results were verified and have concluded using ORB-SLAM because it is a good alternative to SIFT and SURF in terms of computation cost, matching performance, accuracy, and fast detection of keypoint.</p> ER -
