Problems solved by technology

This scheme has a certain degree of automatic control function, but there is a big difference between the angle of rotation on the steering wheel and the angle of the vehicle itself according to different models. In addition to changing lanes, this scheme has certain defects.

specific Embodiment approach

[0082] Combine below Figure 1 to Figure 2 Introduce the specific embodiment of the present invention, specifically comprise the following steps:

[0083] Among them, the following α°=10°, S=0.5m, K=10-100m, a=5 seconds, b=30 seconds

[0084] Step 1: The steering wheel angle sensor measures the car's own angle, and the data is sent to the vehicle controller;

[0085] Step 2: the vehicle controller collects the front image through the front camera, the rear image through the rear camera, the left image through the left camera, and the right image through the right camera;

[0086] Step 3: The vehicle controller analyzes the car's own corner and compares it with the set angle threshold;

[0087] Step 4: The vehicle controller performs image extraction processing on the front image, the rear image, the left image and the right image respectively, and sequentially extracts the front vehicle edge, the rear vehicle edge, the left lane line, and the right lane line;

[0088] The i...

Abstract

The invention discloses a vehicle drive pre-warning system and method based on image monocular vision. The system comprises a steering wheel angle sensor, a front side camera, a rear side camera, a left side camera, a right side camera, a vehicle controller, a voice broadcasting module, a left front lamp relay, a right front lamp relay, a left rear lamp relay, a right rear lamp relay, and a vehicle power supply. The method comprises the following steps: through transmitting an automobile own turning angle measured by the steering wheel angle sensor and images collected by the cameras to the vehicle controller, processing the collected images by using a monocular sighting distance method; and according to data processed by the vehicle controller, judging whether to perform voice broadcast and open a steering lamp. The system is capable of more specifically listing multiple conditions that a vehicle opens the steering lamp, and pre-warning in time; avoiding a situation that a steering wheel angle is changed while the vehicle does not change a lane; and suitable for multiple vehicle models, convenient for operating and using, and capable of avoiding a situation that a driver forgets opening the steering lamp, and improving drive safety.

Description

technical field [0001] The invention relates to the technical field of turn signal control, in particular to a vehicle driving warning system and method based on image monocular vision. Background technique [0002] With the rapid development of my country's economy, every household has their own vehicles. But what follows are accidents caused by driver negligence or inexperience. However, operations such as changing lanes and turning are often required during vehicle driving. When performing these operations, it is necessary to turn on the turn signal in time to remind the vehicles on the side to avoid traffic accidents. [0003] At present, there are existing solutions to detect the upper corner of the steering wheel and the steering wheel, and use the detected corner signal as input to turn on the turn signal, so that other vehicles can be warned to avoid traffic accidents. This scheme has a certain degree of automatic control function, but there is a big difference bet...
