Embodiment Construction

[0036] combine Figure 1 ~ Figure 3 As shown, the hardware structure of an image sensor-based assisted driving device and its working method of the present invention is as follows:

[0037] An image sensor-based assisted driving device, which is composed of an image acquisition system, an image processing system, and an image display system, etc., wherein the image sensor is fixed on the windshield inside the vehicle through a suction cup, or the image sensor is fixed on the top of the vehicle to capture For the road ahead information, the assisted driving system chassis is placed on the instrument panel in front of the driver, and the two are connected through a data cable. The image sensor is fixed with the suction cup through a semi-rigid metal angle iron, and the pitch angle of the image sensor can be changed by adjusting the angle of the angle iron. The embedded processing system and the power supply system are fixed in the chassis, the LCD driver board and the LCD scree...

Abstract

The invention discloses an auxiliary driving device based on an image sensor and a working method thereof, belonging to the field of automobile active safety. The device consists of the image sensor (1), a fan (2), a power supply (3), a liquid crystal drive board (4), a liquid crystal screen (5), a touch screen (6), a touch screen drive board (7), an embedded processing system (8) and an extending device (9); and the auxiliary driving system directly adopts the image sensor as an information sensing part, lane line and vehicle obstacle information is extracted by an image processing algorithmof the embedded system, thus achieving the function of auxiliary driving. The system has compact structure, light weight, low energy consumption, easy operation, good mobility, good detection effect,good timeliness and high performance price ratio, and is applicable to the fields of vehicle auxiliary driving and intelligent vehicle vision navigation.

Description

technical field [0001] The invention relates to an image sensor-based auxiliary driving device and a working method thereof, belonging to the field of automobile active safety. Background technique [0002] Lane line detection and obstacle detection are the prerequisites for intelligent vehicle assisted driving and autonomous obstacle avoidance. The main sensing methods include active sensors such as radar and laser and passive sensors based on vision. Radar and laser have good detection effects and accurate distance measurement, but they cannot detect lane lines, and they have not yet been promoted due to price and other reasons. Vision is an important way for human beings to observe and understand the world, and 90% of the information that drivers need in the process of driving a vehicle comes from vision. Visual image sensors have high cost performance and have been applied in many occasions, such as lane line recognition, road sign recognition, etc., and as passive sens...
