Abstract: The present disclosure provides an automatic correction method and device for a structured-light 3D depth camera. When the optical axis of a laser encoded pattern projector and the optical axis of an image reception sensor change, an offset of an input encoded image relative to an image block in a reference encoded image is acquired, and then the position of the reference encoded image is oppositely adjusted upwards or downwards according to an offset change to form a self-feedback regulation closed-loop system between the center of the input encoded image and the center of the reference encoded image, so that the optimal matching relation can always be figured out when the optical axes of the input encoded image and the reference encoded image change drastically. Furthermore, depth calculation can be carried out according to the corrected offset.

Abstract: The present disclosure provides a time-space coding method and apparatus for generating a structured light coded pattern. Different coded patterns are outputted in time division by driving different light-emitting points based on a regular light-emitting lattice so as to time-space label a target object or a projection space. This method effectively overcomes the limitations of the fact that in the prior art, a plurality of projectors is needed to project different patterns in time division when it is required to project time-space labels of a plurality of patterns. According to the present method, by driving different light-emitting elements on the light-emitting substrate, different coded patterns are formed, and by using a time-division output technology, time-space labeling of an object may be finalized with only one projector. Moreover, this method may significantly improve the accuracy and robustness of three-dimensional depth measurement through time-space coding with a depth decoding algorithm.
