Diver sight line recognition instrument in road driving skill test process and realizing method thereof

Abstract

The invention relates to a diver sight line recognition instrument in a road driving skill test process. The diver sight line recognition instrument comprises a core plate and an interface base plate connected with the core plate, wherein the core plate comprises a DSP (digital signal processor) multi-media digital processing unit, an embedded MCU (microprogrammed control unit), a program memory, a data memory and an interface connector plug-in unit; the DSP multi-media digital processing unit and the embedded MCU are used as the center of the device, and the DSP digital processing unit is in charge of processing digital audio and digital video, so that the necessary status data information for the recognition of the sight line of a driver sitting on the main driver position is obtained. An operation platform for an operating system is provided by the embedded MCU, the interface base plate is also provided with an interface containing the corresponding interface circuit device in addition to the interface connector plug-in unit, and the interface base plate can be externally connected with peripheral devices such as a video camera and the like. According to the diver sight line recognition instrument and a method for realizing the diver sight line recognition in the road driving skill test process, the accuracy and the speed of recognition on the viewing position of the driver sight line are improved.

Description

technical field [0001] The present invention relates to a driving skill test device for a motor vehicle driver, in particular to a driver's line of sight recognition device and a method for realizing driver's line of sight recognition during the road driving skill test process of a car driver to realize driving skill practice guidance and test scoring for a car driver Methods. Background technique [0002] According to the requirements of the industry standard GA / T554-2008 "Site Driving Skills Test System for Motor Vehicle Drivers" formulated by Ministry of Public Security Order No. Front, rear, left and right, whether it is illegal to look down at the gear position, for this reason Nanjing Duolun Technology Co., Ltd.'s patent on "Method for Judging Actual Road Driver Test Based on Facial Image Recognition Technology" (publication number: CN 102306293 A) A method of "detecting the size change of the contour rectangle of facial features" is proposed to deal with the correspo...

AI Technical Summary

Problems solved by technology

In particular, when the camera is facing the head of the driver, when looking left and right or up and down, the angles of the corresponding head swings are similar, and their degree of change is almost the same, so it is impossible to identify the specific viewing direction ;

[0006] 2. The face recognition technology used in the field of security and access control only requires high accuracy and no strict requirements on time, which cannot meet the fast requirements of the driver's license test
