In this embodiment, the lens of the lens module 11 is an aspherical lens. The lens module 110 of the present embodiment includes a retractable lens barrel 111 and a three-grazing aspherical lens 嵌 2 embedded in the retractable lens barrel 111. Two are embedded in the retractable lens barrel 111 and located at The spacers 113 of the three aspherical lenses 11 2 . . . and a driver 114 for driving the telescopic lens barrel 111 to expand and contract. The driver 114 may employ a stepping motor, a voice coil motor or a microelectromechanical motor, and this embodiment employs a microelectromechanical motor. With the cooperation of the driver 114 and the retractable lens barrel 111, the zoom focus function of the camera system 100 can be realized. T〇019] It can be understood that the number of the aspherical lenses 112 is not limited to three, and a lens set of more lenses can be used in order to obtain higher resolution and zoom magnification. 095130428 [〇020] The image sensor 120 can adopt a color charge coupler (CCD) image sensor, a black and white CCD image sensor, and a color complementary metal semiconductor (〇0111卩1611161^3^ Oxide Semiconductor, CMOS) image sensor and black and white CMOS image sensor with resolution ranging from 1.3 megapixels to 6 megapixels 0993183458-0 Form No. A0101 Page 7 of 15 Page 1334831 ___—Ί May 26, 2008, Yongzheng Fan. Considering: (1) CMOS image sensor can meet the requirements of imaging, and the price of CCD image sensor of the same specification is lower than that of CCD image sensor; (2) the redundancy of black and white image is small' The burden of the image analysis system; (3) the resolution of the image needs to be balanced between high image quality and low data volume. Therefore, the embodiment uses a 5 megapixel black and white CMOS image sensor. Of course, other sizes of image sensors can be used, depending on the needs of use. [0021] Please refer to FIG. 3 for the work of the image analysis system 200. flow chart. The image analysis system 200 first performs a receiving signal step S01, and receives image information output by the camera system 100; and then performs a filtering process step S02' to filter the received image information to filter out noise in the image information, highlighting The lane separation line 3 is _? value; then the judgment processing step S03 'extracts the characteristic value of the lane separation line 30 and judges whether the sway rate value is within the safe range, that is, whether it is dangerous driving; the rabbit judges the lane separation When the sloshing rate value of the line 30 exceeds the safe range, the safety control signal is output to start the ampere device 3〇〇, and the output full control signal step S04 is performed; if it is judged that the swaying rate of the lane dividing line 3〇 is in the text Within the range, the safety control signal is not output, and the step S05 is not outputted. In this embodiment, the threshold value of the output security control signal is 100 pixels/5 seconds, that is, when the image analysis system 2 analyzes that the lane separation line 30 sways more than 1 in 5 seconds. A security control signal is output when the pixel is turned off. Below this rate, the security control signal is not output. Of course, the threshold is only a reference value, and can be changed according to the specific needs. 095130428 Form No. A0101 Page 8 / Total 15 Page 0993183458-0 [0023] Correction of π 'T, y image analysis process on May 26, 099 In the middle, the roadside vines, the lane separation line 30 is faded, and the like, the image information captured by the camera system 100 is doped with multi-noise, and the image analysis system 200 is difficult to accurately extract the characteristic values of the lane separation line 3, so The image information captured by the camera system 100 is subjected to filtering processing. The filtering process step S02 may employ a Fast Foufier Transform (FFT) or a Discrete Cosine Transform (DCT) as a filter processing algorithm. The example uses FFT as the filtering processing algorithm. [0024] The software of the image analysis system can be set such that the image analysis system 200 only activates the alarm 3 to generate a report within a preset time period in which the sway rate of the lane separation line 3 超过 exceeds the safe range. In this case, the automatic braking device 3〇2 is set to be set to prevent the image analysis system 200 from being misjudged to cause great trouble to the driving. [0025] In this embodiment, the image analyzing system 200 analyzes the lane separation. The alarm 30 is activated within 1 second before the line 30 sway rate exceeds the safe range. If the driver does not respond to the alarm, the automatic brake device 3 启动 2 is activated. ♦ Of course, this setting can also be changed according to specific needs. [0026] In summary, the vehicle safety system 10 can alert the driver to the alarm when the driver is unconscious and unable to control the driving direction. Automatic braking is started without response, to ensure safe driving and prevent traffic accidents caused by dangerous driving.
