US 2017/0285161 A1 · Object Detection Using Radar And Vision Defined Image Detection Zone

Abstract

An object-detection system includes a radar sensor, a camera, and a controller. The radar-sensor is suitable for mounting on a vehicle and is used to detect a radar-signal reflected by an object in a radar-field-of-view. The radar-signal is indicative of a range, range-rate, and a direction to the object relative to the vehicle. The camera is used to capture an image of a camera-field-of-view that overlaps the radar-field-of-view. The controller is in communication with the radar-sensor and the camera. The controller is configured to determine a range-map for the image based on the range and the direction of the radar detection, define a detection-zone in the image based on the range-map, and process only the detection-zone of the image to determine an identity of the object.

Dependent claims

An object-detection system configured to detect an object proximate to a vehicle, said system comprising:

a radar-sensor suitable for mounting on a vehicle and used to detect a radar-signal reflected by an object in a radar-field-of-view, said radar-signal indicative of a range and a direction to the object relative to the vehicle;
a camera used to capture an image of a camera-field-of-view that overlaps the radar-field-of-view;
and
a controller in communication with the radar-sensor and the camera, said controller configured to determine a range-map for the image based on the range and the direction, define a detection-zone in the image based on the range-map, and process only the detection-zone of the image to determine an identity of the object.
