Imaging system positioning method and device thereof for human body scanner

Abstract

The present invention discloses an imaging system positioning method for a human body scanner. The method comprises the steps of setting a calibration body provided with a calibration block; obtaining the three-dimensional coordinates of the calibration block on the calibration body; comparing the three-dimensional coordinates of the calibration block with the preset feature encoding of the calibration block; adjusting the position of a camera set to complete the positioning of the camera set. The present invention also discloses an imaging system positioning device for the human body scanner. According to the technical scheme of the invention, the camera set of the human body scanner is adjusted through setting the calibration body, so that the shooting angle and the shooting distance of the camera set are at preset positions. Therefore, the accuracy of the human body scanning process is improved.

[0002] Three-dimensional scanning is a high-tech that integrates light, machine, and charge computer technology. It is mainly used to scan the spatial shape, structure and color of objects to obtain the spatial coordinates of the object surface. Its significance lies in the ability to convert the three-dimensional information of objects Converting to digital signals that can be directly processed by the computer provides a very convenient means for the digitization of physical objects. However, traditional 3D scanning equipment is mostly contact scanners or laser scanners. The contact measurement speed is slow and the mechanical structure is complicated, which cannot meet the requirements The needs of modern measurement, and laser scanners have radiation effects on the human body, which can easily cause discomfort to the human body, which greatly limits the use of laser scanners

[0003] In order to solve the shortcomings of contact scanners and laser scanners in human body scanning, a non-contact camera scanning device is currently used for human body scanning. By taking pictures of the human body in multiple directions and processing the images, the three-dimensional coordinates of the human body can be obtained. , so as to construct a three-dimensional human body model. In this method, the accuracy of obtaining the three-dimensional coordinates of the human body determines the accuracy of the construction of the three-dimensional human body model. For the photographic scanning device, due to the installation deviation of the components, the installation of the camera is different from the design position. There is a deviation, which leads to inaccurate 3D coordinates obtained by image processing after taking pictures, which leads to inaccurate 3D modeling
