Embodiment 1

[0049] Such as Figure 1-2 As shown, in the specific embodiment of the present invention, an anti-blocking automobile A-pillar blind spot monitoring device is provided, including: a car body 1, a front windshield 2, and two flexible display screens embedded in the car body 1, processing chip and sensor 5; also includes the first automobile A-pillar 3 and the second automobile A-pillar 4 formed by bending backwards at the left and right ends of the front windshield 2;

[0050] The first and second automobile A-pillar outsides are respectively equipped with a wide-angle camera; the wide-angle camera includes a first wide-angle camera 6 and a second wide-angle camera 7; On the reversing mirror on the same side as the A-pillar of the first automobile, it is used to collect wide-angle panoramic image data outside the A-pillar of the first automobile; The reversing mirror on the same side of the A-pillar of the second car is used to collect wide-angle panoramic image data outside t...

Embodiment 2

[0076] Based on the same inventive concept, the specific embodiment of the present invention also provides an anti-blocking method for monitoring the A-pillar blind spot of an automobile, such as Figure 4 shown, including the following steps:

[0077] S1 respectively selects the length center of the first and second automobile A-pillars as the origin of polar coordinates, and establishes the first and second polar coordinate systems;

[0078] S2 detects the arc length and angle value between the human eye position and the polar coordinate origin on the first and second polar coordinate systems;

[0079] S3 defines the arc length and angle value between the driver's eye position and the polar coordinate origin on the first and second polar coordinate systems in the unobstructed state as the expected field of view parameter;

[0080] S4 compares the arc length and angle value between the current human eye position acquired in real time and the polar coordinate origins on the f...

Abstract

The invention relates to an anti-shielding automobile A-pillar blind area monitoring device and method. The anti-shielding automobile A-pillar blind area monitoring device comprises an automobile body, a front windshield, and two flexible display screens, a processing chip and a sensor which are embedded in the automobile body, and also comprises a first automobile column A and a second automobilecolumn A which are formed after the left end and the right end of the front windshield are bent backwards respectively; a first wide-angle camera and a second wide-angle camera are respectively mounted on the outer sides of the first automobile column A and the second automobile column A; the first wide-angle camera is embedded in the middle upper part of the first automobile column A or arrangedon a rearview mirror on the same side as the first automobile column A, and is used for acquiring wide-angle panoramic image data on the outer side of the first automobile column A; and the second wide-angle camera is embedded in the middle upper part of the second automobile column A or arranged on a rearview mirror on the same side as the second automobile A column, and is used for acquiring wide-angle panoramic image data on the outer side of the second automobile column A. The scheme can be used for a driver to avoid a blind area in the driving process, widen the visual field and effectively guarantee the driving safety.

Description

technical field [0001] The invention relates to the technical field of automobile safety prevention and control, in particular to an anti-blocking automobile A-pillar blind area monitoring device and method. Background technique [0002] Cars are the main means of transportation on land and are becoming more and more popular in modern life. Due to the existence of the A-pillar in existing cars, the front view where the A-pillar is located cannot be known, so that there is a blind spot in the front view of the car. If pedestrians or obstacles appear In this blind spot, driving safety cannot be effectively guaranteed. [0003] The A-pillar of a car is one of the important components of the car and plays a vital role in the crashworthiness of the car. But its existence has caused the driver's very big sight blind spot, because the existence of blind spot very easily causes major traffic accident, and the present automobile A-pillar blind spot problem has not found effective so...
