Occupancy Mapping. buildMap The occupancy grid is a multidimensional random field that maintains stochastic estimates of the occupancy state of the cells in a spatial lattice Occupancy Grid Map The occupancy grid map (OGM) is a promising navigation map type for robots, capable of distinguishing between occupied, free, and unknown environmental areas through ray casting and handling sensor noise and dynamic objects through probabilistic updates

In this project, the occupancy grid mapping algorithm is impelmented to construct a map with assumption that the robot's poses are known To construct a sensor-derived map of the robot's world, the cell state estimates are obtained by interpreting the incoming range readings using probabilistic sensor models.

In occupancy grid map, the space is discretized into independent cells and each cell associates a. Each cell in the occupancy grid has a value representing the probability of the occupancy of that cell. Create Egocentric Occupancy Maps Using Range Sensors Occupancy Maps offer a simple yet robust way of representing an environment for robotic applications by mapping the continuous world-space to a discrete data structure

Twodimensional example of occupancy mapping using the Hilbert maps. 1 Occupancy Mapping: An Introduction Occupancy Grid Mapping refers to a family of computer algorithms in probabilistic robotics for mobile robots which address the problem of generating maps from noisy and uncertain sensor measurement data, with the assumption that the robot pose is known.
