Dual vision front vehicle safety warning device and method thereof

Abstract

The invention provides a dual-vision preceding vehicle safety attention device and method. The dual-vision preceding vehicle safety attention device comprises an image capturing unit, a vehicle body signal sensing unit, an image processing unit, a system attention judging logic and at least one attention unit, wherein the image capturing unit comprising at least two photographic devices is arranged on a vehicle so as to capture an image on a road ahead environment, then the image processing unit is used for processing the image and calculating the distance from the vehicle and a preceding vehicle in the image by matching with a vehicle body signal sensed by the vehicle body signal sensing unit, when the vehicle deviates a driveway or is in an over-short distance with the preceding vehicle, the system attention judging logic sends out a control signal to the attention unit so as to drive the attention unit to send out an attention signal through sound, lighting and other effects and towarn the driver of the vehicle.

Description

technical field [0001] The invention relates to a technology for providing a warning of a safe distance from a vehicle in front, in particular to a dual-vision vehicle safety warning device and method thereof. Background technique [0002] In the past, various front vehicle safety warning systems mostly used laser and radar to estimate the distance between the vehicle in front and the obstacle, and then used the distance estimation result to prevent the front collision situation. However, this kind of system is not only expensive, but also has no The functions of road recognition such as deviation and road sign recognition, so the market visibility of the front vehicle safety warning system is quite low. [0003] In view of this, the image-based front vehicle safety warning system has gradually received attention. Compared with laser and radar, image capture has the advantages of traffic environment identification (such as lane lines, traffic signs, obstacles), powerful inte...

[0002] In the past, various front vehicle safety warning systems mostly used laser and radar to estimate the distance between the vehicle in front and the obstacle, and then used the distance estimation result to prevent the front collision situation. However, this kind of system is not only expensive, but also has no The functions of road recognition such as deviation and road sign recognition, so the market visibility of the front vehicle safety warning system is quite low

[0003] In view of this, the image-based front vehicle safety warning system has gradually received attention. Compared with laser and radar, image capture has the advantages of traffic environment identification (such as lane lines, traffic signs, obstacles), powerful integration functions, and lower prices. However, due to the different selection of lenses, the video type front vehicle safety warning system cannot take into account the short-range and long-range detection capabilities at the same time. Long-distance detection related products, but in the automotive imaging system, the larger the detection range of the system, the better, and the more the system can identify the road environment, the better. Obviously, none of the above methods can meet these requirements at the same time
