Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 1:
2. The method for intelligently measuring vehicle trajectory based on a binocular stereo vision system according to claim 1, wherein the SSD neural network in step 1 is formed on a basis of a classical SSD neural network by removing a convolutional layer conv11_2 and reserving convolutional layers conv4_3, cony_7, conv8_2, conv9_2 and conv10_2, wherein a feature information in different scales extracted by the convolutional layers conv4_3, conv7, conv8_2, conv9_2, and conv10_2 is fused and input into a classifier, wherein the position of the license plate is predicted according to the feature maps output by the convolutional layers.
