Embodiment Construction

[0029] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] Such as figure 1 As shown, the embodiment of the present invention provides a method for an intelligent driving car to early warning of road potholes, including the following steps:

[0031] S1. Based on the vehicle-mounted infrared light curtain group, the acquisition of the front ground scanning image is realized, and at the same time, based on the vehicle-mounted vehicle state perception module, the perception of vehicle driving state parameters is realized;

[0032] S2. Realize the identification of the type of potholes and their location information based on the scanned image of the ground ahead;

[0033] S3. Based on the Rssd_ince...

Abstract

The invention relates to the field of intelligent driving obstacle avoidance, in particular to a road surface bumpy upheaval early warning method for an intelligent driving automobile, which comprisesthe steps of realizing acquisition of a front ground scanning image based on a vehicle-mounted infrared light curtain group, and realizing perception of automobile driving state parameters based on avehicle-mounted automobile state perception module; based on the front ground scanning image, recognizing the pit upheaval type and the position information; recognizing the shape of the built-in bumpy upheaval in the front ground scanning image, and calculating the size of the bumpy upheaval according to the recognition result; judging whether the automobile passes through the pothole upheaval or not based on the position of the pothole upheaval and the automobile driving state parameters; and according to a judgment result, starting different early warning algorithms to realize early warning of the bumpy upheaval based on the bumpy upheaval type, the location information and the size information. Accurate positions and size information of pits and upheaval can be scanned and determinedin real time, automatic lane changing and active obstacle avoiding are achieved, and therefore the safety of automobile driving can be improved.

Description

technical field [0001] The invention relates to the field of intelligent driving obstacle avoidance, in particular to an intelligent driving vehicle early warning method for road potholes. Background technique [0002] At present, most intelligent driving vehicles obtain the surrounding environment information through various sensors installed on the vehicle, and then use certain methods to extract information useful for intelligent behavior decision-making in the environmental data through the automatic driving computer system, such as detecting obstacles and detecting lanes. Lines, traffic sign recognition, vehicle positioning, environmental sound recognition, etc., and then realize assisted driving based on this information. [0003] At present, the early warning of road potholes and bumps at home and abroad is mainly realized through contact, that is, when the vehicle passes over potholes or bumps, the existence of potholes or bumps is detected through the body sensor, a...
