Problems solved by technology

Such methods require artificially designed features, have limited representation capabilities in complex scenes, and output steering intentions are not practical in some complex intersections
[0007] It can be seen that the current prediction method is difficult to accurately predict the driving intention of the target vehicle in some complex intersection situations

Embodiment Construction

[0121] The embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0122] The inventor of the present application has found that there are still some problems when training a vehicle intention prediction model by a deep learning-based method in the prior art, such as:

[0123] 1) Low coding efficiency: The above method adopts a non-fixed coordinate system, that is, the position and orientation of the target vehicle at the current moment are used as the coordinate reference, and each frame of data needs to be rasterized separately, which takes a lot of time.

[0124] 2) Insufficient generalization performance: The above method converts the target vehicle intention prediction problem into a twelve-element classification problem. The twelve-element category corresponds to different sectors in the target vehicle coordinate system. In practical applications, the target vehicle exit do...

Abstract

The embodiment of the invention provides a vehicle intention prediction method and a related device, and the method comprises the steps: obtaining an intention prediction model which is used for predicting the driving intention of a vehicle in all directions of an intersection; performing rasterization coding on the target driving data to obtain a target image sample, wherein different types of data in the target driving data and data corresponding to different exit directions are respectively coded into different data channels in one image sample; and inputting the target image sample into the intention prediction model to obtain the intention probability of driving of the second vehicle in each direction of the intersection. According to the embodiment of the invention, the intention prediction accuracy of the vehicle in a complex road condition can be improved.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, and in particular, to a vehicle intention prediction method and a related device. Background technique [0002] With the development of intelligent driving technology, intelligent vehicles have become the key research targets of major manufacturers. Intelligent driving includes assisted driving and automatic driving, and the key technologies for its realization are: positioning, perception, prediction, planning control, etc. Vehicle intention prediction refers to predicting the behavior intention of the target vehicle according to the target vehicle state at the current moment and historical moment. For example, in the forward road scene, the vehicle intention can include lane keeping, left lane change, right lane change, etc., in the intersection scene The intent to get off the vehicle may include going straight, turning left, turning right, and U-turn. On urban roads, real-time, ...
