Method for reconstructing three-dimensional object combining structured light and photometry and terminal device

A method for reconstructing a three-dimensional object combining structured light and photometry, comprising:

• acquiring N first images, wherein each first image is obtained by shooting after a coded pattern having a coding stripe sequence is projected to a three-dimensional object, and N is a positive integer;
• determining structured light depth information of the three-dimensional object based on the N first images;
• acquiring M second images, wherein the M second images are obtained by shooting after P light sources are respectively projected to the three-dimensional object from different directions, and M and P are positive integers;
• determining photometric information of the three-dimensional object based on the M second images;
• and
• reconstructing the three-dimensional object based on the structured light depth information and the photometric information,
• wherein reconstructing the three-dimensional object based on the structured light depth information and the photometric information comprises:
• iteratively calibrating the structured light depth information based on the photometric information to obtain calibration deviation information relative to the structured light depth information;
• determining whether the calibration deviation information meets a preset iteration termination condition or not;
• and
• if yes, reconstructing the three-dimensional object based on calibrated structured light depth information correspondingly meeting the iteration termination condition.
