Abstract
A generation apparatus that generates a virtual viewpoint image based on a plurality of captured images obtained by a plurality of cameras and virtual viewpoint information, and includes: a generation unit configured to generate a virtual viewpoint image by a generation method determined from a plurality of generation methods for generating a virtual viewpoint image: a changing unit configured to change the generation method for generating a virtual viewpoint image from a first generation method to a second generation method; and a control unit configured to perform control to restrain a change of the generation method by the changing unit.
Claims17
A generation apparatus comprising:
- one or more memories configured to store instructions;
- and
- one or more processors communicatively connected to the one or more memories and configured to execute the instructions to function as:
- a generation unit configured to generate, based on a plurality of captured images obtained by a plurality of image capturing apparatuses and virtual viewpoint information, a virtual viewpoint image by a generation method determined from a plurality of generation methods for generating the virtual viewpoint image:
- a changing unit configured to change the generation method to be used by the generation unit for generating the virtual viewpoint image from a first generation method to a second generation method;
- and
- a control unit configured to determine whether to perform control to restrain the change of the generation method by the changing unit, depending on evaluation information relating to a degree of a change, in the virtual viewpoint image, caused as a result from the change of the generation method of the virtual viewpoint image from the first generation method to the second generation method.
A control method comprising:
- determining a generation method for generating, based on a plurality of captured images obtained by a plurality of image capturing apparatuses and virtual viewpoint information, a virtual viewpoint image from a plurality of generation methods;
- performing control to change the generation method for generating the virtual viewpoint image from a first generation method to a second generation method;
- and
- determining whether to perform control to restrain the change of the generation method depending on evaluation information relating to a degree of a change, in the virtual viewpoint image, caused as a result from the change of the generation method of the virtual viewpoint image from the first generation method to the second generation method.
A non-transitory computer readable storage medium storing a program for causing a computer to perform a control method comprising:
- determining a generation method for generating, based on a plurality of captured images obtained by a plurality of image capturing apparatuses and virtual viewpoint information, a virtual viewpoint image from a plurality of generation methods;
- performing control to change the generation method for generating the virtual viewpoint image from a first generation method to a second generation method;
- and
- determining whether to perform control to restrain the change of the generation method depending on evaluation information relating to a degree of a change, in the virtual viewpoint image, caused as a result from the change of the generation method of the virtual viewpoint image from the first generation method to the second generation method.
