Embodiment Construction

[0040] Below in conjunction with specific embodiment, the present invention is further described:

[0041] like figure 1 As shown, the auxiliary vision system for the blind area of ​​the A-pillar field of view based on the eye-tracking technology in this embodiment includes an eye-tracking unit 1, an ECU unit 2, an external camera unit 3 and an indoor display unit 4; wherein, the eye-tracking unit 1 , the external camera unit 3 and the indoor display unit 4 are respectively connected to the ECU unit 2 .

[0042] The functions of each unit are as follows:

[0043] The eye tracking unit 1 is installed on the inner side of the front windshield of the car, and is used to locate the driver's eyes and send the positioning information to the ECU unit 2;

[0044] The ECU unit 2 is used to receive the positioning information sent by the eye tracking unit 1, and control the external camera unit 3 to move and collect the road condition information of the blind area of ​​the A-pillar fi...

Abstract

The invention discloses an auxiliary vision system and method for the blind area of ​​A-pillar field of view based on eye tracking technology. The eye tracking unit is used to locate the driver's human eyes, and the positioning information is sent to the ECU unit; the ECU unit receives the data sent by the eye tracking unit. After the positioning information, control the movement of the external camera unit to collect the road condition information of the blind area of ​​the A-pillar field of vision according to the positioning information; the external camera unit, under the control of the ECU unit, follows the driver's vision and moves to collect the road condition information of the blind area of ​​the A-pillar field of view; the indoor display unit Displays the road condition information of the blind area of ​​the A-pillar field of view collected by the external camera unit. The external camera unit in the present invention can perform multi-dimensional adjustment such as front and rear, up and down, angle, etc., so that the camera acquisition meets the needs of eye tracking, achieves the purpose of completely eliminating the blind area of ​​the column, and achieves the goal of electronic transparency.

Description

technical field [0001] The invention relates to the technical field of automotive vision, in particular to an auxiliary vision system and method for the blind area of ​​the A-pillar visual field based on the eye tracking technology. Background technique [0002] With the continuous improvement of people's living standards and the increasing popularity of automobiles, the safety and comfort of automobiles are particularly important. However, due to the existence of the blind spot of the A-pillar of the car, when the driver drives the vehicle into a curve, it may cause a side collision accident, which affects the safety of driving; or the driver usually needs to lean forward to observe the front in order to avoid the accident ( Especially the left front) road conditions, affecting its driving comfort. [0003] At present, the commonly used methods to solve the blind spot of automobiles are as follows: 1) Open triangular windows or install reversing stickers on the car pillars...
