Embodiment Construction
[0050] The present invention will be further described below in conjunction with the accompanying drawings. Such as figure 1 Shown is the flow chart of the method of vehicle front passability analysis based on convolutional neural network. The present invention takes the structured environment of the expressway as an example, and divides the environment in front of the vehicle into vehicles, road boundaries and road surfaces.
[0051] The analysis process of the present invention includes: image acquisition, image preprocessing, and convolutional neural network training.
[0052] A. Image acquisition
[0053] A large number of real highway driving environment images (640×480 pixels) are collected by the camera installed in front of the vehicle, and then the lower three-fifths of the image are used as the region of interest (640×288 pixels) to reduce the follow-up workload ; Finally, convert the cropped image to a grayscale image.
[0054] B. Image preprocessing
[0055] ...
