Title:
METHOD FOR EVALUATING DEGREE OF TOWING POINT OF POINT CLOUD OF LASER RADAR, AND TEST APPARATUS AND LASER RADAR
Document Type and Number:
WIPO Patent Application WO/2023/197528
Kind Code:
A1
Abstract:
A method for evaluating the degree of a towing point of a point cloud of a laser radar, and a test apparatus, a laser radar and a computer-readable storage medium. The method comprises: building a test apparatus, which comprises a base, a first target object and a second target object; mounting a laser radar on the base, such that light emitted by the laser radar can be incident to the first target object and the second target object; emitting detection pulses to the first target object and the second target object of the test apparatus by means of the laser radar; receiving echo pulses of the detection pulses that are reflected by the first target object and the second target object, and generating a point cloud on the basis of the echo pulses; determining whether there is a towing point in the point cloud; and when there is a towing point in the point cloud, increasing the distance between the first target object and the second target object, repeating the steps until there is no towing point in the point cloud, and recording the distance between the first target object and the second target object at this moment, which recorded distance is used for representing the degree of the towing point of the point cloud of the laser radar. The test apparatus comprises a base, a first target object and a second target object. The laser radar comprises an emitting unit, a receiving unit and a processing unit. The computer-readable storage medium comprises a computer-executable instruction stored therein, wherein a method is implemented when the executable instruction is executed by a processor.
