Here's how tracking might work in a vSLAM system: # The robot captures a sequence of images with its camera as it moves through the environment. # For each new image, the robot identifies features (distinct..." current

As a robot moves through an environment, it builds a map of the environment and uses that map to estimate its location within it. However, as the robot moves, small errors in its motion estimates can accumulate over time, leading to drift in the estimated trajectory and the map. The idea of loop closure is to correct thi..." current

The idea is to focus computational resources on understanding the robot's immediate surroundings in detail, rather than attempting to map the entire environment at once. This local map is continuously updated as the robot moves..." current
