Investigation And Analysis On The Present Situation Of Rural Left Behind Children’s Mathematics Learning

With the development of economy and society, taking the automobile dominated transportation tools grow with each passing day, the road as a carrier of automobile traffic, the traffic information includes whether has the important instruction function to the human driving a car or unmanned vehicle. This paper studied on the part of road traffic information in the scene, and put forward a new method to solve some key technical problems in traffic scenes. Because of the natural scene under the road traffic is extremely complex, which makes the quick find signs region is particularly important, the establishment of the region of interest is one of the effective ways to solve the problem. By using the inverse perspective transformation can not only establish the desired region of interest, but also on the lane line in the image information to be correct, it provides convenience for subsequent marker detection and lane detection In order to research the road traffic identification, this paper proposes a segmentation method of average gray of global and local average gray approximation of the optimal threshold based on image segmentation, and the establishment of standards will be compared with the method of Otsu method and iterative threshold method. In order to detect the middle of the road zebra, zebra line shape feature based method is proposed in this paper, the horizontal projection based on the zebra crossing is detected.
