Image training sample generation method and device

The invention discloses an image training sample generation method and device, and belongs to the field of computer vision. According to the method, the model transformation is carried out on the obtained three-dimensional texture model of the target object to obtain a plurality of three-dimensional transformation models, and then one or more two-dimensional images corresponding to each three-dimensional transformation model are generated, so that a large number of image training samples similar to the target object can be obtained. That is to say, the scheme can quickly and automatically generate a large number of image training samples meeting requirements, and manpower and time costs are saved. Moreover, because the image training samples in the scheme are obtained according to the three-dimensional texture model of the target object, the image training samples and the target object belong to the same type, and the fidelity is high. Thus, compared with an image training sample captured from the Internet, t
