The present invention discloses a depth sensing method, device and system based on symbols array plane structured light. The coded symbols array pattern is projected by the laser pattern projector to the target object or space, and the image sensor collects and obtains the successive sequence of the encoded image of the input symbols. Firstly, the input image encoded with the symbols is decoded. The decoding process includes preprocessing, symbols location, symbols recognition and symbols correction. Secondly, the disparity of the decoded symbols are calculated by the symbols match calculation between the decoded image of the input symbols with completed symbols recognition and the decoded image of the reference symbols with the known distance. Finally the depth calculation formula is combined to generate depth point cloud information of the target object or projection space that is represented in the form of grid. The present invention can quickly obtain high-resolution and high-precision depth information of the target object or projection space in dynamic scenes, which facilitates the porting or insertion as a module into the intelligent device for 3D modeling, 3D mapping, etc.

An apparatus comprised of a plurality of engagement structures independently movable along a longitudinal axis to initially engage a mid-foot region of a foot is described.
