Vehicle orientation determining method and device and vehicle-mounted terminal

Abstract

The embodiment of the invention discloses a vehicle orientation determining method and device and a vehicle-mounted terminal. The method comprises the steps of determining a vehicle area and a licenseplate area where a to-be-detected vehicle is located in a road image through a vehicle detection model; according to the relative position relationship between the vehicle area and the license platearea, determining the width-to-height size ratio of the to-be-detected vehicle; determining structure line information of the the to-be-detected vehicle from the vehicle area through a vehicle structure line detection model based on the width-to-height size ratio; determining orientation information corresponding to the structural line information as orientation information of the to-be-detected vehicle according to a preset corresponding relationship between the orientation information and the structural line information; wherein the vehicle structural line detection model is used for determining structural line information of the to-be-detected vehicle from the vehicle area according to pre-trained model parameters and the width-to-height size ratio of the to-be-detected vehicle. By applying the scheme provided by the embodiment of the invention, the orientation information of the vehicle can be determined more accurately.

Description

technical field [0001] The present invention relates to the technical field of intelligent driving, in particular, to a method, device and vehicle-mounted terminal for determining vehicle orientation. Background technique [0002] With the development of science and technology, emerging concepts such as intelligent driving and unmanned vehicles have emerged as the times require. High-precision vehicle detection, recognition, and tracking estimation are important elements in road scene analysis and environmental perception, and are also an indispensable part of the field of intelligent driving. Estimating the vehicle orientation of surrounding vehicles is an important part of perception technology. In addition to determining the vehicle orientation of surrounding vehicles in the field of intelligent driving, it will also be used in other fields, such as road monitoring. [0003] In the related technology, the road image including the vehicle to be detected is usually collec...
