METHOD AND SYSTEM FOR ANALYZING THE DISTANCE TO AN OBJECT IN AN IMAGE

机译:用于分析图像中对象距离的方法和系统

摘要

A controller/application synchronizes a camera's image capture rate with a LIDAR light burst rate. The controller instructs LIDAR to direct bursts within a field of view of the camera. When reflection of energy of a given burst is detected, the controller/application instructs an image recognition/analysis application to determine object characteristics by evaluating pixels of an image corresponding to the given burst within an evaluation range that corresponds to the location to which the burst was directed during an aperture open period when the camera captured the image. The controller may also instruct the LIDAR to determine a distance to an object that reflected the energy of the given burst. Based on the determined distance to the object and object characteristics, the controller may generate a take-action message. The take-action message may include instruction for controlling an autonomous vehicle to avoid interaction with the object that reflected energy of the burst.
