The driving safety maintenance system 1 includes a > flying vehicle starting unit 10, a photographing unit 2A, a processing unit 30, a wiper 40, and a storage unit 5G. The car engine unit 1 is used to start eight cars. The car is driven under the control of the driver. The shooting unit reads the occlusion of the windshield in front of the driver. 098145930 Form No. A0101 Page 5 of 12 0982078369-0 201121820 Body image, the camera unit 20 can be mounted on the rear mirror of the car. The wiper 40 is used to scrape off coverings on the windshield, such as raindrops. The storage unit 50 is used to store sharpness similar to a circular contoured obscuration image. The processing unit 30 further includes an image intercepting unit 32, an image processing unit 34, an image determining unit 36, and a calculating unit 38. The image capturing unit 32 is configured to capture a stereoscopic image of the obstruction on the windshield captured by the photographing unit 20 for a predetermined time. The image processing unit 34 is configured to perform image edge processing on the stereoscopic image of the obstructed windshield on the intercepted windshield. The sharpness of the image is obtained, and the sharpness of the piano includes parameters such as the shape and area of the image. For example, when raindrops are scattered on the windshield, the falling raindrops are shaped like a circular shape on the windshield, and the image processing unit 34 performs image edge on the circular contoured raindrops. The treatment results in the sharpness of the raindrops on the windshield. The image determining unit 36 is configured to determine whether the sharpness of the stereoscopic image of the obstructing object on the windshield belongs to a predetermined range, that is, to determine whether the sharpness of the stereoscopic image of the object is good, and the brightness is good. The sharpness of the image belongs to the predetermined range, which means that the driving sight in front of the driver is good; if the sharpness of the image does not belong to the predetermined range, the obstruction on the windshield affects the driving sight in front of the driver, which will result in It is impossible to judge the road conditions in front of the car. [0009] When the image determining unit 36 determines that the sharpness of the stereoscopic image of the obstructing object on the windshield does not belong to the predetermined range, the image determining unit 36 determines whether the sharpness of the image is equal to the storage unit 5 〇 Stored image sharpness. When it is judged that the image sharpness of the obstruction on the windshield is the image sharpness stored in the storage unit 50, the occlusion on the windshield 098145930 Form No. A0101 Page 6 / Total 12 pages 0982078369-0 201121820 The object is raindrop The calculating unit 38 calculates the frequency at which the raindrops fall on the windshield according to the stereoscopic image captured by the image capturing unit 32, and the image determining unit 36 determines the magnitude of the rainfall according to the frequency at which the raindrop falls on the windshield to activate the wiper 40. And adjust the frequency of the wiper 4 〇 rain. [0010] ❹ Figure 2 is the flow of the maintenance method (4) of the present.
