Information processing apparatus, control method thereof, and recording medium

A control method of an information processing apparatus, the method comprising:

• dividing each of input depth data and image data corresponding to the input depth data and having a higher resolution than the input depth data into a plurality of divided regions;
• inferring depth data by complementing input depth data with image data for each of the divided regions;
• and
• combining depth data having a higher resolution than input depth data by combining inferred depth data in the divided region,
• wherein, in the dividing, division is performed such that each divided region has an overlapping region partially overlapping with an adjacent divided region,
• wherein the combining processing unit extracts a feature amount of the overlap region in the divided region and combines depth data in the overlap region based on the feature amount.

A non-transitory storage medium storing a control program of an information processing apparatus causing a computer to perform each step of a control method of the information processing apparatus, the method comprising:

• dividing each of input depth data and image data corresponding to the input depth data and having a higher resolution than the input depth data into a plurality of divided regions;
• inferring depth data by complementing input depth data with image data for each of the divided regions;
• and
• combining depth data having a higher resolution than input depth data by combining inferred depth data in the divided region,
• wherein, in the dividing, division is performed such that each divided region has an overlapping region partially overlapping with an adjacent divided region,
• wherein the combining processing unit extracts a feature amount of the overlap region in the divided region and combines depth data in the overlap region based on the feature amount.

An information processing apparatus comprising:

• at least one processor and/or circuit configured to function as following units:
• a division processing unit configured to divide each of input depth data and image data corresponding to the input depth data and having a higher resolution than the input depth data into a plurality of divided regions;
• an inference processing unit configured to infer depth data by complementing input depth data with image data for each of the divided regions;
• and
• a combining processing unit configured to combine depth data having a higher resolution than that of input depth data by combining inferred depth data in the divided regions,
• wherein the division processing unit performs division such that each divided region has an overlap region partially overlapping with an adjacent divided region,
• wherein the division processing unit divides each of the input depth data and the image data into a plurality of divided regions by a plurality of division methods, divided regions divided by the same division method do not have an overlap region, and divided regions divided by different division methods have an overlap region, and
• wherein the combining processing unit combines depth data according to a distance from the center of an overlapping divided region, during combination of the overlapping region.
