Title:
METHOD AND SYSTEM FOR OPERATING A MOVABLE PLATFORM USING RAY-CASTING MAPPING
Document Type and Number:
WIPO Patent Application WO/2018/218508
Kind Code:
A1
Abstract:
Systems and methods are used to plan a route for a movable platform. Sensor data representing location information of one or more objects adjacent the movable platform is obtained at a first time point. A new grid map of the first time point is generated by updating an existing grid map at a second time point prior to the first time point based on the sensor data at the first time point. Each grid map includes a plurality of grid cells each having a value representing a clearance status of ray casting through the grid cell at a corresponding time point. The route for the movable platform is updated based on the respective values of the plurality of grid cells of the new grid map.
