Embodiment Construction

[0053] The present invention will be further described below in conjunction with the accompanying drawings.

[0054] The processing modules involved in this scheme are as follows: figure 1 As shown, it includes an image acquisition module 1 , a face image detection module 2 , a gaze direction determination module 3 and a signal transmission module 4 .

[0055] Image acquisition unit 1 such as figure 2 As shown, it is composed of an acquisition unit 11 and a data processing unit 12 . Wherein, the collection unit 11 adopts a monocular or binocular camera to collect the in-vehicle image, and transmits the collected in-vehicle image to the data processing unit 12 through the network, and then performs preliminary processing on the image.

[0056]When the hardware of acquisition unit 11 is installed, the camera needs to be installed in front of the steering wheel in the case of monocular, to ensure that the camera images of drivers of different sizes can completely contain the d...

Abstract

The invention discloses a method and a system for judging the face sight direction of an examinee in a driving test. The method comprises the following steps: acquiring an in-vehicle image of a driver seat area; detecting the in-vehicle image by utilizing the face target detection model, determining whether a face image exists or not, and if yes, inputting the face image into a face sight line direction classification model to calculate confidence coefficients of the face image in preset N types of face sight line directions respectively; and classifying the face image into a face sight line direction with the maximum confidence value. The system includes a memory for storing dataset computer program instructions, and a processor in communication with the memory. The processor executes the computer program instructions to perform the steps of the decision method. The technical scheme is mainly suitable for driving test subjects III, and can quickly and accurately make a judgment on the line-of-sight attention direction of a driver, uploads the judgment result to the scoring system, and assists an examiner to make a fair score.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence judgment for a motor vehicle driving license test, in particular to a method and a system for judging the direction of a human face line of sight of a test taker in a driving test. Background technique [0002] With the continuous development of the social economy and the continuous improvement of people's living standards, the number of urban motor vehicles has increased rapidly, and the number of people applying for driver's license examinations has also continued to increase every year. The workload of the driver's license test has also increased. [0003] The traditional driver's license test judgment is mainly through manual judgment, and the examiner sits side by side with the driver, so it is difficult to accurately check and judge the direction of the examiner's attention. [0004] At present, the technical means that can be used to check the driver's sight direction in th...
