Abstract
A device includes one or more processors configured to receive radar data, and generate a plurality of occupancy grid maps based on the radar data. Each of the occupancy grid maps corresponds to a respective one of a plurality of candidate angles. The one or more processors is also configured to select one of the candidate angles as a sensor mount angle based on the occupancy grid maps, and trigger an action based on the sensor mount angle and the radar data.
Claims20
A device, comprising:
- one or more processors configured to:
- receive radar data;
- generate, based on the radar data, a first occupancy grid map corresponding to a first candidate angle;
- determine a first number of grid cells occupied for an object in the first occupancy grid map;
- generate, based on the radar data, a second occupancy grid map corresponding to a second candidate angle;
- determine a second number of grid cells occupied for the object in the second occupancy grid map;
- select the first candidate angle as a sensor mount angle in response to determining that the first number is less than the second number;
- and
- trigger an action based on the sensor mount angle and the radar data.

5 more elements
A vehicle, comprising:
- a radar sensor configured to receive radar signals reflected by an object;
- one or more processors coupled to the radar sensor, and configured to:
- generate, based on the radar signals, a first occupancy grid map corresponding to a first candidate angle;
- determine a first number of grid cells occupied for the object in the first occupancy grid map;
- generate, based on the radar signals, a second occupancy grid map corresponding to a second candidate angle;
- determine a second number of grid cells occupied for the object in the second occupancy grid map;
- select the first candidate angle as a mount angle of the radar sensor in response to determining that the first number is less than the second number;
- and
- control the vehicle based on the mount angle and the radar signals.
