Abstract

The invention discloses a navigation action prediction model training method and device, and a navigation action generation method and device. A training sample set is constructed, wherein the training sample set comprises one or more training samples, the training samples are image data containing a driving-in road section and a driving-out road section at an intersection, and marks of the training samples are used for representing navigation actions from the driving-in road section to the driving-out road section; and a navigation action prediction model is trained based on the training sample set. Therefore, a navigation action prediction model of which the prediction accuracy can be guaranteed and the accuracy of the prediction result can be evaluated can be obtained.

Description

technical field [0001] The present disclosure relates to the field of road navigation, in particular to a navigation action prediction model training method, a navigation action generation method and a device. Background technique [0002] Navigation action generation is an important part of navigation services. [0003] Navigation actions refer to steering actions that should be performed at intersections, such as turning left, going straight, and so on. [0004] The traditional navigation action generation method is mainly to intercept the in-road section and the out-road section, and determine the navigation action that should be executed at the intersection by calculating the in-road section and the out-road section. Since the road network is very complex, it is necessary to verify the generated navigation actions to obtain reliable navigation actions. [0005] The above-mentioned navigation action generation method has the following problems: 1. The key road section t...
