Abstract

The invention relates to an environment detection method in an unmanned vehicle target search system, which comprises the following steps of S1, creating an unmanned vehicle global environment map andan onboard camera field of view coverage map; S2, performing combined environment search on a target to be searched at a current position, extracting and evaluating edge regions to determine the target point position of the unmanned vehicle in the next step; S3, generating a collision-free desired path, controlling the unmanned vehicle to reach the target point position; and S4, determining whether the target to be searched is located at the target point position, and completing the environment detection if so, or returning to the S1 if not. The method realizes the autonomous environment detection based on edge region guidance in an unknown environment and realizes efficient search for the target to be detected in an unknown region, and a planned travel path realistically reflects the driving characteristics of the vehicle.

Description

technical field [0001] The invention relates to the technical field of unmanned vehicles, in particular to an environment detection method in an unmanned vehicle target search system. Background technique [0002] As an important research field of robotics, autonomous detection technology in unknown environments is widely used in scenarios without prior environmental information. In fact, in many practical applications, a priori environmental information is not available, so the robot must have the ability to autonomously detect the environment in an unknown working environment in order to complete other tasks such as navigation and target search. At present, the environment detection strategy based on the guidance of the edge area is widely used on omnidirectional small mobile robots. Usually, the environment detection strategy is combined with the synchronous positioning and map creation technology to complete the task of creating an environment map for the unknown environ...
