Embodiment Construction
[0037] In order to describe in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in conjunction with specific embodiments and accompanying drawings.
[0038] The present invention proposes a road environment visual perception method based on improved Faster R-CNN, which comprises the following steps:
[0039] S1. Before the input image enters the network model, it is first scaled to 1600*700, and then enters the ResNet-101 feature extraction network in the Featureextraction network module, such as figure 2 shown. After the Conv1, Conv2_x, Conv3_x, and Conv4_x of ResNet-101 have a total of 91 layers of fully convolutional networks, the Feature maps of the pictures are extracted;
[0040] S2. The Feature maps output by the Feature extraction network module enter the Regionproposal network module, such as figure 1 shown. The Region proposal network module uses a 3*3 sliding window to traver...
