Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0033] like Figure 1-4 reported increase,
[0034] A traffic sign recognition method based on color space fusion network and space transformation network, its flow chart is as follows figure 1 , the specific steps are:
[0035] Step 1: Preprocess the traffic sign dataset and divide the dataset into training set, validation set and test set.
[0036] As an example, the traffic sign dataset is selected from the German Traffic Sign Recognition Bechmark. The training set of the dataset contains 39,209 pictures, and the test set contains 12,630 pictures. The data set preprocessing process in step 1 is to normalize the size of the image of the data set to 48×48 through the bilinear interpolation algorithm; divide the pixel value of the image by 255 to realize the normalization of the pixel value; The ratio of 9:1 is split into training set and validation...
