Abstract

The invention discloses a target detection method and device, relates to the technical field of information processing, in particular to the field of automatic driving or intelligent traffic, and aims to solve the problems of under-segmentation and over-segmentation in a target recognition process by optimizing and updating a clustering result of a three-dimensional point cloud in combination with image detection information of a target scene image, thereby improving the target identification accuracy. Specifically, an under-segmentation problem in a preliminary clustering process can be identified through the coincidence degree of a preliminarily clustered three-dimensional point cloud and a target detection frame after image detection; by comprehensively analyzing the overlap ratio of the three-dimensional point cloud subjected to preliminary clustering and the target detection frames after image detection and the target preset size corresponding to each target detection frame, the over-segmentation problem in the preliminary clustering process can be identified, and the result can be corrected.

Description

technical field [0001] The embodiments of the present application relate to the technical field of information processing, and in particular, to a target detection method and device in the field of automatic driving or intelligent transportation. Background technique [0002] A variety of 3D point perception modules, such as laser sensors, radar, sonar or ultrasonic sensors, are usually configured in an advanced driver assistant system (ADAS) or autonomous driving (AD) system to sense the surrounding area. Environmental and target information. By sensing the surrounding environment and targets, target recognition can be completed, thereby effectively avoiding obstacles and increasing the comfort and safety of autonomous driving. Among them, the above-mentioned targets such as vehicles, pedestrians, guardrails, road stakes, bushes, light poles, vehicle access poles / blocking poles, overpass culverts or buildings, etc. Generally, the above-mentioned 3D point perception module...
