LiDAR Human Modeling Method

Abstract

The present invention relates to the technical field of laser scanning, and discloses a laser radar human body modeling method, which specifically includes the following steps: S1: the image acquisition device scans the side area of ​​the human body, captures the spatial lattice distribution of the edge of the human body, and passes through the spatial point Schematic diagram of array distribution to obtain the preliminary structure of the human body model, compare the preliminary structure of the human body model with the real data of the human body, and adjust the value of the preliminary structure of the human body model; S2: The image acquisition device performs contour line connection fitting on the provided model contour edge point matrix, A spatial linear matrix is ​​formed, and the spatial linear matrix is ​​fitted in different spaces to form different surface matrices, and finally the initial shape model of the human body is formed. The present invention captures the spatial lattice distribution of the edge of the human body by laser, obtains the rough outline of the human body model, and compares and adjusts the preliminary structure of the human body model with real data to achieve the integrity of the model.

Description

technical field [0001] The patent of the present invention relates to the technical field of laser scanning, in particular, to the laser radar human body modeling method. Background technique [0002] The mainstream technology of 3D human body scanning can be divided into two types: passive scanning and active scanning. Among them, the active three-dimensional scanning technology includes laser scanning, structured light scanning, time-of-flight method, etc., the existing three-dimensional body scanning system, such as Cyberware based on the principle of laser scanning in the United States, has high precision but is expensive (more than two hundred thousand US dollars). ); scan the human body from multiple perspectives, the scanning time is fast, and the whole body scan can be completed within 5 seconds, but the color reproduction is average, and the equipment price is relatively high; the RDS Bodyscan human body scanner developed by Xi'an Jiaotong University is fast, The a...

Problems solved by technology

Among them, the active three-dimensional scanning technology includes laser scanning, structured light scanning, time-of-flight method, etc., the existing three-dimensional body scanning system, such as Cyberware based on the principle of laser scanning in the United States, has high precision but is expensive (more than two hundred thousand US dollars). ); scan the human body from multiple perspectives, the scanning time is fast, and the whole body scan can be completed within 5 seconds, but the color reproduction is average, and the equipment price is relatively high; the RDS Bodyscan human body scanner developed by Xi'an Jiaotong University is fast, The accuracy is high, but invisible infrared waves can cause certain harm to the human body, and its price is more than one million RMB; the price of Artec handheld 3D scanner is relatively low (100,000 RMB), but the scanning time is long and the scanned people need to maintain a certain position for 3 to 5 minutes

[0003] In the prior art, the mainstream technology of 3D human body scanning takes a long time to scan, and the principle of scanning is to scan in different areas, and finally the whole board is spliced ​​to complete the construction of the overall model, so splicing after the construction is completed will easily cause misalignment , thus affecting the integrity of the model, and the concavity and convexity of the surface treatment of the model are relatively blurred, which makes the constructed human body model unable to be used by doctors for diagnosis
