Embodiment 1

[0032] Such as Figure 1-6As shown, the present invention provides a method for continuously playing structured light stripe patterns, including the following steps: S100: Arranging multiple horizontal stripe patterns and vertical stripe patterns according to set rules, preferably grouping horizontal stripe patterns and vertical stripe patterns , that is, multiple horizontal stripes are put together to form a horizontal stripe group, and multiple vertical stripes are put together to form a vertical stripe group, which is convenient for numbering multiple horizontal stripes and vertical stripes. It needs to be sorted according to the density of the horizontal and vertical stripes, so that the whole sorting and the subsequent playback of the structured light machine are easier. S200: Perform preprocessing on a plurality of horizontal stripe images and vertical stripe images to obtain a horizontal stripe sample image and a vertical stripe sample image respectively. The preprocess...

Embodiment 2

[0043] The present invention also provides a 3D structured light machine, including: one or more microprocessors; a storage module, one or more of the microprocessors is used to execute one or more programs stored in the storage module, so that One or more microprocessors execute the method for continuously playing the structured light fringe pattern of the present invention. The 3D structured light optical machine provided by the present invention realizes the continuous playback of multiple horizontal and vertical stripe images, and the interval time between the playback of the structured light fringe images is short, which improves the acquisition accuracy and quality of the structured light information, and realizes the Faster and more efficient measurement of measured objects. At the same time, only writing the horizontal gray value row matrix and the vertical gray value row matrix into the 3D structured optical machine compresses the storage space and reduces the running...

Abstract

The invention discloses a continuous playing method of a structured light fringe pattern and a 3D structured light machine, relates to the technical field of 3D structured light, and solves the technical problem that the playing interval of the structured light fringe pattern is long. The method comprises the following steps: S100, arranging a plurality of horizontal fringe patterns and vertical fringe patterns according to a set rule; s200, preprocessing the plurality of horizontal stripe patterns and the plurality of vertical stripe patterns to respectively obtain horizontal stripe pattern patterns and vertical stripe pattern patterns; s300, obtaining an original transverse gray value row matrix and a vertical gray value row matrix; s400, adding a flag bit at the head part and adding a filling bit at the tail part in each original transverse gray value row matrix to obtain a transverse gray value row matrix; s500, adding serial number bits in the transverse gray value row matrix and the vertical gray value row matrix respectively, and writing the serial number bits into a 3D structured light machine; and S600, playing the plurality of transverse fringe patterns and the plurality of vertical fringe patterns. According to the invention, continuous playing of a plurality of transverse fringe diagrams and vertical fringe diagrams is realized, the playing time interval is short, and the acquisition precision and quality of structured light information are improved.

Description

technical field [0001] The invention relates to the technical field of 3D structured light, in particular to a method for continuously playing structured light fringe patterns and a 3D structured light machine. Background technique [0002] 3D structured light is a three-dimensional light source with a pattern containing three-dimensional structure size information. It is used in three-dimensional measurement and other occasions. It does not need to touch the surface of the object. It has the advantages of high accuracy, fast measurement speed, and low cost. The core component is a 3D structure. Optical machine. It is widely used in many industries such as industry, medical treatment, communication, and security. Its specific functions include detection, positioning, measurement, and material sorting. When in use, the structured light emitted by the 3D structured light machine is projected onto the object to be measured, so that the surface of the object is calibrated with ...
