Embodiment Construction

[0042] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0043] Artificial Intelligence (AI) is a theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results. In other words, artificial intelligence is a comprehensive technique of computer science that attempts to understand the nature of intelligence and produce a new kind of intelligent machine that can respond in a similar way to human intelligence. Artificial intelligence is to study the design principles and implementation methods of various intelligent machines, so that the machines have the functions of perception, reasoning and de...

Abstract

The invention discloses an obstacle detection and marking method and device for automatic driving and a storage medium, and relates to the field of automatic driving. The method comprises the following steps: collecting an environment image collected by a camera and a laser point cloud collected by a laser radar; the method comprises the following steps: constructing a pseudo point cloud corresponding to an environment image by performing three-dimensional reconstruction on the environment image; point cloud fusion is carried out on the laser point cloud and the pseudo point cloud to generatetarget point cloud, and the data size of the target point cloud is not smaller than that of the laser point cloud; and the target point cloud is input into an obstacle detector, an obstacle detectionresult output by the obstacle detector is obtained, and the obstacle detector is a detector based on point cloud coding. The embodiment of the invention provides a universal point cloud detection framework, so that image data can also be applied to point cloud detection, and the accuracy of obstacle detection is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of automatic driving, and in particular to an obstacle detection and marking method, device and storage medium for automatic driving. Background technique [0002] Autonomous driving is a technology that uses computer equipment to control vehicles to drive automatically on the road. The realization of automatic driving relies on the cooperation of artificial intelligence, visual computing, radar and positioning components. [0003] Since the actual road conditions are complex and there are a large number of obstacles such as pedestrians and vehicles, how to realize obstacle recognition and then plan a driving route to avoid obstacles has become the key to automatic driving. In related technologies, a vehicle supporting automatic driving is usually provided with a LiDAR (Light Detection And Ranging, LiDAR) or a camera. Among them, when the laser radar is used to detect obstacles, the laser ...
