Abstract

The invention provides an obstacle track prediction method and device, electronic equipment and an automatic driving vehicle, and relates to the field of automatic driving and intelligent transportation. According to the specific implementation scheme, firstly, road information of a current vehicle in a driving area and sampling information obtained by sampling at least one moving obstacle in the historical driving process of the current vehicle are obtained, and then attitude information of the at least one moving obstacle is determined according to the sampling information; and the attitude information at least comprises the shape information of the moving obstacle, and then the moving track of at least one moving obstacle at the next moment is predicted according to the road information and the attitude information of the moving obstacle. According to the invention, the problem of inaccurate obstacle track prediction result in the prior art is at least solved.

Description

technical field [0001] The present disclosure relates to the technical fields of automatic driving and intelligent transportation, and in particular, to a method, device, electronic equipment and automatic driving vehicle for predicting obstacle trajectories. Background technique [0002] When the vehicle moves autonomously, it is necessary to predict the position, attitude and speed of the vehicle in the future, so as to know the information of the surrounding obstacles in advance, and predict the direction of the obstacles in the future, so as to avoid moving During the process, the vehicle collides with the obstacle. [0003] Among them, the existing technology usually uses a semantic map or a vector network to predict the trajectory of obstacles. However, the semantic map needs to be drawn in real time and requires a lot of calculations, which leads to the problem of inaccurate obstacle trajectory prediction results. The vector network does not treat obstacles different...
