Claim 9:
10. An image view angle conversion device, comprising:
a memory storing processor-executable instructions; and
a processor configured to execute the stored processor-executable instructions to perform operations of:
acquiring model training data, the model training data comprising planar images of a training object at a plurality of different view angles and labels corresponding to respective view angles, wherein the labels corresponding to the different view angles are different;
training a pre-designed generative adversarial network model according to the model training data to obtain a view angle conversion network model; and
inputting a planar image of a target object and labels corresponding to one or more expected view angles of the target object into the view angle conversion network model, so that the view angle conversion network model generates planar images of the target object at the expected view angles;
wherein the labels comprise encoding vectors, and the generative adversarial network model comprises a generator G and a discriminator D,
acquiring the view angle conversion network model comprises:
acquiring a preset input image x and a preset input encoding vector c of the training object;
acquiring a pre-generated image G(x, c) output by the generator G according to the preset input image x and the preset input encoding vector c;
determining an adversarial loss Ladv according to the pre-generated image G(x, c) and a probability distribution D(x) of the discriminator D, wherein the adversarial loss Ladv is defined as:

Ladv=Ex[log D(x)]+Ex,c[log(1−D(G(x,c)))]; and

calculating a target value of the adversarial loss Ladv such that the probability distribution D(x) of the discriminator D takes a maximum value while the pre-generated image G(x, c) takes a minimum value.
