Problems solved by technology

Although minor and general accidents will not cause serious casualties and major property losses, they will cause traffic jams and bring great trouble to road traffic.
[0003] A large part of the reason is that the driver's driving habits are not standardized, especially in the process of vehicle lane change, there is no habit of checking the rearview mirror in advance, resulting in traffic accidents when changing lanes
At present, there is no equipment for statistical analysis of drivers' driving habits, which is still a blank in the automotive industry

Embodiment 1

[0036] See figure 1 and figure 2 , figure 1 It is a schematic structural diagram of a system for improving driving safety provided by an embodiment of the present invention, figure 2 It is a schematic diagram of the outline structure of an eye testing device provided by an embodiment of the present invention. The system 10 may include an eye testing device 11 and a driving system detection and analysis device 12 . The driving system detection and analysis device 12 is arranged inside the car, including a voice prompt unit and a processing unit, wherein the processing unit can be arranged at the center console position of the car, and the voice prompt unit can be integrated with the speaker system in the car, It can also be installed separately in the cab, which is not limited here.

[0037] Wherein, the eye testing device 13 can be a glasses structure, which can include a frame body 131, mirror legs 133, and the eye collecting device 13 also includes a pupil image collec...

Embodiment 2

[0047] See image 3 , image 3 It is a schematic diagram of a method for improving driving safety provided by an embodiment of the present invention. The method can include:

[0048] Step 1, collect the first eye image of the testee after prompting the testee to watch the specific point of the car;

[0049] Step 2. Determine the line of sight direction of the testee according to the first eye image and the position of the specific point of the car corresponding to the first eye image to complete the initialization of line of sight positioning;

[0050] Step 3. When prompting the subject to change lanes, collect the second eye image of the subject;

[0051] Step 4. Determine the testee's gaze direction according to the second eye image and the mapping model initially established for gaze positioning to form driving habit detection and analysis data.

[0052] Specifically, step 1 may include:

[0053] Step 11, control the indicator light that is set on the rear view mirror ...

Embodiment 3

[0064] See Figure 4 , Figure 4 It is a schematic diagram of an initialization method for line-of-sight positioning provided by an embodiment of the present invention. In this embodiment, on the basis of the foregoing embodiments, the initialization process is described in detail as follows:

[0065] Step a, performing grayscale processing on the first eye image to form a first grayscale image;

[0066] Step b, determining the first pupil center point according to the first grayscale image;

[0067] Step c, forming a mapping relationship between the position of the first pupil center point and the position of the corresponding specific point of the vehicle to complete the initialization of the gaze positioning.

[0068] Specifically, step a may include:

[0069] Step a1, performing enhancement processing on the first eye image;

[0070] Step a2, performing filtering processing on the pair of eye images.

[0071] Among them, the pupil image is firstly preprocessed to for...

Abstract

The present invention relates to a system and method for improving driving safety. The method includes that in the initialization stage, the voice prompt unit prompts the subject to observe the observation point set at a specific point of the car, the eye test equipment collects the first eye image of the subject observing the observation point, and the processing unit according to the eye The images and observation points are processed to complete the initialization of sight positioning; in the test phase, the voice prompt unit prompts the testee to change lanes, and at the same time, the eye test equipment collects the second eye image of the testee, and the processing unit according to the second The eye image determines and records the gaze direction of the testee to form driving habit monitoring and analysis data. The invention can monitor, discriminate, evaluate and give real-time warnings to drivers' bad habits when changing lanes during driving training, can encourage drivers to gradually develop good driving habits, and eliminate traffic accidents, vehicle failures and hidden dangers to human health.

Description

technical field [0001] The invention belongs to the technical field of traffic, and in particular relates to a system and method for improving driving safety. Background technique [0002] With the vigorous development of my country's automobile industry, the number of urban and rural residents owning cars is rapidly expanding, and bad driving habits of drivers will cause hidden dangers of traffic accidents, hidden dangers of vehicle failure and hidden dangers to the health of people in the car. According to incomplete statistics, the number of deaths due to traffic accidents in my country is as high as more than 100,000 people every year, not to mention minor and general accidents. Although minor and general accidents will not cause serious casualties and major property losses, they will cause traffic jams and bring great trouble to road traffic. [0003] A large part of the reason is that the driver's driving habits are not standardized, especially in the process of vehic...
