Abstract

The invention provides a vehicle intelligent navigation method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a video stream collected by a target vehicle in an automatic navigation advancing process; obtaining a video frame from the video stream; determining an area conforming to the color of the road traffic sign in the video frame through color difference; performing shape feature screening in the determined area to obtain a road traffic sign area image; obtaining a road traffic sign feature vector of the road traffic sign area image; processing the road traffic sign feature vector by using a trained road traffic sign classification model, and predicting a traffic sign category to which the road traffic sign area image belongs; and according to the predicted traffic sign category to which the road traffic sign area image belongs, sending a navigation instruction matched with the road traffic sign area image so as to control the driving of the target vehicle. The method can accurately predict the traffic sign type of the road traffic sign area.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a vehicle intelligent navigation method, device, electronic equipment and storage medium. Background technique [0002] With the rapid development of smart cars and driverless technology, the recognition of road traffic signs has become an important part of safe driving. Road traffic signs are used to warn, prohibit, restrict and instruct road users. Road traffic signs are generally set on the sign boards on both sides of the road surface in the form of labels, or directly drawn on the road surface. In related technologies, the accuracy of recognition of road traffic sign areas and prediction of traffic sign categories is poor. [0003] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and therefore may include information that does not constitute ...
