A method for generating an image of a three-dimensional object in a virtual three-dimensional space includes using a virtual camera in the three-dimensional space. The method includes updating a position and / or orientation of the virtual camera in response to a change in a position of at least one vanishing point existing on a picture plane and corresponding to infinity of coordinate axes. The method includes generating the image of the three-dimensional object using the updated virtual camera. The updating includes changing the position and / or orientation of the virtual camera in a case where the changed position of the vanishing point is returned to the position of the vanishing point before the change in the position of the vanishing point, the updated position and / or orientation of the virtual camera is returned to the position and / or orientation of the virtual camera before the change in the position of the vanishing point.

The application discloses an image plane region detection method based on edge information. Firstly, a neural network is used to extract basic skeleton network features of each level of an image. Then, each level feature obtained is extracted into multi-level context features through upsampling and interlayer linking. The intermediate level feature obtained is extracted into multi-level edge features of the image through iterative optimization network layers, and different level features are optimized into expected feature dimensions. The multi-level context features and the multi-level edge features are fused in pairs layer by layer. Finally, the fused features are provided to a target model of a downstream image plane detection task to be trained, so as to improve the performance of the target model in the downstream image plane detection task.
