Abstract: The present disclosure relates to systems and methods for determining a motion of an object during imaging. The systems and methods may cause a light emission device to project a structured light onto the object, and cause a light reception device to detect light resulting from the structured light as projected onto the object and generate a plurality of measured images of the structured light based on the detected light. The systems and methods may further determine the motion of the object based on the plurality of measured images of the structured light and a reference image of the structured light.

Abstract: A data processing method includes obtaining a first input data of a user, the first input data being displayed in a first section and outputting a first content in a second section different from the first section based on the first input data. The first content includes a plurality of sub-contents. The plurality of sub-contents are based on phrases correlated with the first input data. The first content prompts for input corresponding contents at a plurality of target positions corresponding to the plurality of the sub-contents. The plurality of target positions are correlated with the phrases corresponding to the plurality of sub-contents.
