Boundary approximation utilizing radar

Abstract:

Systems and methods for boundary approximation utilizing radar are disclosed. For example, a heatmap of an environment may be generated utilizing data from reflected energy received at a device. The heatmap may be utilized to generate a point cloud representing the environment, where points of the point cloud indicate rates of change of energy intensity associated with surfaces in the environment. The points may be utilized to determine a mean line indicating an approximated distance between a portion of the environment, such as a wall, and the device.
