METHODS AND APPARATUS FOR OBJECT DETECTION AND IDENTIFICATION IN A MULTIPLE DETECTOR LIDAR ARRAY

摘要

LiDAR (light detection and ranging) systems use one or more emitters and a detector array to cover a given field of view where the emitters each emit a single pulse or a multi-pulse packet of light that is sampled by the detector array. On each emitter cycle the detector array will sample the incoming signal intensity at the pre-determined sampling frequency that generates two or more samples per emitted light packet to allow for volumetric analysis of the retroreflected signal portion of each emitted light packet as reflected by one or more objects in the field of view and then received by each detector.

1. A LiDAR (light detection and ranging) system comprising:
an emitter that emits a series of emitted light packets over a field of view, each emitted light packet emitted for a cycle duration; a detector array having an array of detectors configured to cover the field of view and sample an incoming retroreflected signal portion of an emitted light packet at a pre-determined sampling frequency that generates at least two samples corresponding to the cycle duration of the emitted light packet; a processing system configured to analyze the samples from the detector array and detect any objects within the field of view using at least a volumetric analysis of the at least two samples from each detector in the array of detectors corresponding to the incoming retroreflected signal portion of each emitted light packet.
