Abstract
A method of generating a depth map corresponding to input data includes providing light to a target object in a plurality of patterns that change over time, obtaining a plurality of captured images respectively corresponding to the plurality of patterns, by photographing the target object to which the light is provided, obtaining the input data by preprocessing the plurality of captured images and generating the depth map based on the input data.
Claims18
A method of generating a depth map corresponding to input data, the method comprising:
- providing light to a target object in a plurality of patterns that change over time;
- obtaining a plurality of captured images respectively corresponding to the plurality of patterns, by photographing the target object to which the light is provided;
- obtaining a plurality of illumination images respectively corresponding to the plurality of patterns by photographing a light-emitting device configured to provide the light;
- obtaining the input data by preprocessing the plurality of captured images and the plurality of illumination images;
- and
- generating the depth map based on the input data.
An electronic device for generating a depth map corresponding to input data, the electronic device comprising:
- a light-emitting device configured to provide light to a target object in a plurality of patterns that change over time;
- a measuring device comprising at least one camera configured to obtain a plurality of captured images respectively corresponding to the plurality of patterns by photographing the target object to which the light is provided;
- a memory storing one or more instructions;
- and
- at least one processor configured to execute the one or more instructions stored in the memory to:
- receive a plurality of illumination images that are previously captured, the plurality of illumination images being obtained by photographing the light-emitting device, the plurality of illumination images respectively corresponding to the plurality of patterns;
- obtain the input data by preprocessing the plurality of captured images and the plurality of illumination images, and
- generate the depth map based on the input data.
A non-transitory computer-readable recording medium storing instructions that, when executed by at least one processor, cause the at least one processor to:
- provide light toward a target object in a plurality of patterns that change over time;
- obtain a plurality of captured images respectively corresponding to the plurality of patterns, by photographing the target object toward which the light is provided;
- obtain a plurality of illumination images respectively corresponding to the plurality of patterns by photographing a light-emitting device configured to provide the light;
- obtain input data by preprocessing the plurality of captured images and the plurality of illumination images;
- and
- generate a depth map based on the input data.
