Problems solved by technology
In contrast, the difficulty of single pattern coding and decoding is significantly higher than that of multiple time-domain coding. The essential reason is that the information that a single pattern can carry is limited, and various defects are inevitable, especially the difficult extraction of code points leads to a low decoding rate. , reducing the accuracy of the decoded data
Therefore, the existing methods can only decode static images, and it is still difficult to break through the bottleneck in the decoding of dynamic images, and the scope of application is also greatly limited. The encoding will directly affect the detection accuracy and resolution, and the detection of projected images and identification methods will be limited accordingly

A projection structured light system detection method comprises the following steps: S100, projecting a mask on a projection target through projection of a projection module to form a projected image; S200, receiving the projected image through a receiving device; and S300, importing the projection image to a processing device, and automatically identifying the projected image through detection software in the processing device to objectively get the performance and parameter information of the projection module.
Description
technical field [0001] The invention relates to a detection method, in particular to a detection method of a projection structured light system for automatic detection and identification of projection modules. Background technique [0002] With the rapid development of the global smart phone industry, people's requirements for the functions and quality of mobile phones are increasing day by day. In addition to the pursuit of mobile phone application software, people's requirements for camera functions are also increasing. The past two-dimensional shooting technology can no longer To meet the needs of the market, people yearn for the more and more popular 3D imaging technology. The original camera, which was only used as an input device, becomes a device with more breadth and depth functions, so that the camera not only collects signals from one plane, but also It realizes three-dimensional imaging through structured light, and further realizes depth expansion functions such ...
