Problems solved by technology

[0010] In order to overcome the disadvantages of single detection means, low discrimination accuracy, and low measurement accuracy of existing safety driving assistance devices, the present invention provides a device that uses an omnidirectional visual sensor to simultaneously detect the state of the driver's face and the state of the eyes. State, state of the mouth, state of the steering wheel, monitoring the direction of the vehicle, monitoring the speed of the vehicle, etc., comprehensively detects the characteristic parameters of the driving fatigue state, with high discrimination accuracy and improved measurement accuracy. An all-round computer vision-based safety driving assistance device

Embodiment Construction

[0108] The present invention will be further described below in conjunction with the accompanying drawings.

[0109] Referring to Figures 1 to 13, a safety driving assistance device based on omnidirectional computer vision, first obtains the perspective view of the driver's seat, the perspective of the steering wheel, and the perspective view of the driving road environment through the omnidirectional visual sensor; the perspective view of the driver's seat is used for For the driver's face detection, mouth detection, eye detection, and facial trajectory detection, image understanding and recognition can be used to judge the driver's perceived state and whether the state is in a fatigue state; through the understanding of the perspective view of the steering wheel to judge driving Whether the driver's action state is slow to respond, slow to judge, stiff in movement, slow in rhythm, etc.; get the road environment and vehicle running track through the perspective view of the veh...

Abstract

The auxiliary safety operation equipment based on omnibearing computer vision includes an omnibearing vision sensor for acquiring omnibearing video information outside and inside the vehicle, and an auxiliary safety operation controller for detecting fatigue operation and warning on fatigue operation. The omnibearing vision sensor installed in the right of the driver's seat and connected to the auxiliary safety operation controller detects the facial state, eye state and mouth state of the driver and the steering wheel state, monitors the vehicle direction, speed, etc, and warns the fatigue operation in case of detecting fatigue operation state. The present invention detects the characteristic parameter of fatigue operation state, and has high judgment precision and high measurement precision.

Description

(1) Technical field [0001] The invention belongs to the application of omnidirectional visual sensor technology, image recognition and understanding technology, and computer control technology in vehicle safety driving, in particular to a safe driving auxiliary device based on omnidirectional computer vision. (2) Background technology [0002] Figure 1 shows the driving model of the road environment, the driver, and the car. During the entire driving process, the driver continuously performs perception-judgment-action, and the interference factors that exist at any time, such as perception fatigue, judgment fatigue, and action fatigue, will affect driving at any time. The normal operation of the driver until the end of the driving, any fatigue alone or together may cause the risk of driving failure. [0003] The traffic information first passes through the driver's perception stage. In this stage, the driver perceives various information in the road environment. The sensing ...
