AI Technical Summary

Problems solved by technology

The system can only judge rainy or foggy weather, and cannot judge the frosting condition inside the window glass. The degree of intelligence is not high, so in actual application, it may lead to misjudgment
In addition, the system is only a single judgment process and cannot monitor the entire driving process.

Embodiment Construction

[0066] The method of the present invention can refer to Figure 1-4 Enumerate the preferred embodiment to carry out.

[0067] now refer to figure 1 , figure 1 is a flowchart of the first embodiment of the method of the present invention. In this embodiment, step 102 is executed through a CCD / CMOS camera installed on the back of the interior rearview mirror, that is, image information is regularly collected, wherein the area where the image is collected is within the wiper area of ​​the windshield. After the image is collected, the image processing step 104 is performed, which includes decolorizing the image to form a black and white image, and then processing it with a large contrast to enhance the light and dark contrast of the image, and searching for the edge line of the image accordingly to obtain a line drawing of the collected image .

[0068] Due to different weather conditions or different degrees of blur in the wiper area of ​​the windshield, the collected image m...

Abstract

The invention provides a vehicle-mounted intelligent control method, which comprises the following steps: firstly, collecting images of a vehicle windshield glass rain scraping zone through an image collecting device, secondly, processing collected images, thirdly, recognizing the articulation of the images, comparing the articulation with the threshold value, fourthly, executing according to the comparison result, and fifthly returning to the first step or the second step to control an external device. The invention provides a device for using the method on the other hand, the device does not have complicated circuit design, and thereby both the method and the structure are simpler. The images are caught through a mode of collecting the images, which is different from receiving photoelectrons, and thereby the device is not affected by external factors and also can not pollute electromagnetic environment in the vehicle. The method and the device not only can judge rain and snow weather automatically, but also can recognize fog or frost weather, and can control corresponding external devices with pertinence, thereby realizing high intelligent operations.

Description

technical field [0001] The invention relates to a vehicle intelligent control method and device, in particular to a method and device for automatically controlling the external equipment of the vehicle according to the recognition result of the image definition. Background technique [0002] During the driving process of the car, often due to weather reasons, the driver needs to choose to turn on the wiper, fog lamp or defroster. However, manual operation is troublesome, and often due to untimely operation (such as sudden splashing of water), the vision is blurred, which affects driving and even leads to car accidents. [0003] The existing solution is to provide an automatic wiper system, which mostly uses active photoelectric detection technology. The principle is to use an infrared optical transmitter to project light on the windshield window. When there is sewage or rain on the windshield, the amount of reflected light will change, so that the photoelectric receiver wi...
