Embodiment 1
[0036] This embodiment provides a vehicle re-identification method;
[0037] Such as figure 1 As shown, a vehicle re-identification method includes:
[0038] According to the three-dimensional model of each model, rotate the angle to get the picture of each angle, extract the key point information of each model and the outer contour information of the model, and calculate the rotation angle;
[0039] Input the key point information of each vehicle type, the outline information of the vehicle type, and the rotation angle into the vehicle re-identification model to obtain a trained vehicle re-identification model;
[0040] Input the picture or video of the vehicle to be tested into the trained vehicle re-identification model, and output the model of the vehicle to be tested.
[0041] Among them, it is first necessary to establish a three-dimensional model of each vehicle type.
[0042] As an example, Unity 3D software can be used to carry out 3D modeling of the collected vehi...
