Low-cost and high-definition human body three-dimensional scanning imaging system based on feature point supplementation

Abstract

The invention discloses a low-cost and high-definition human body three-dimensional scanning imaging system based on feature point supplementation. The system comprises a frame assembly including cameras, the frame assembly comprises a shell in a sphere structure, the inner surface of the shell is provided with the cameras, the shell is also provided with an LED light-supplementing lamp and feature point supplementing lamps, each feature point supplementing lamp comprises a high-light LED lamp, an optical lens and an imaging lens, the imaging lens is provided with a random two-dimensional barcode, the projection lamp projects a pattern corresponding to the random two-dimensional barcode, the random two-dimensional barcode is formed by square spots with a certain density, the random two-dimensional barcodes projected by all the feature point supplementing lamps cover a target human body located in the shell, a union of the shooting ranges of all the cameras covers the whole target human body, the random two-dimensional barcode projected by the same feature point supplementing lamp is completely shot by at least two cameras, the shooting angles of all the cameras can be adjusted, and the project directions of the feature point supplementing lamps can be adjusted.

Description

technical field [0001] The invention relates to a three-dimensional scanner device, which is specifically used for three-dimensional data collection and modeling restoration of objects. Background technique [0002] At present, the following 3D scanning devices are widely used in the market: [0003] 1. Hand-held scanners: This type of scanner requires the target body to remain stationary, scan it layer by layer according to the front, back, left, and right, and then complete the three-dimensional modeling through computer processing, which takes a long time to scan; [0004] 2. Panoramic human body scanning system: this type of scanning system is a simple upright structure, and the height and angle range of the scanning must be adjusted manually. Model, there are defects such as unstable structure, complicated debugging, large scanning blind spots, high equipment cost, complicated post-processing, and lack of color texture in the generated 3D model; [0005] At the same t...

Problems solved by technology

[0003] 1. Hand-held scanners: This type of scanner requires the target body to remain stationary, scan it layer by layer according to the front, back, left, and right, and then complete the three-dimensional modeling through computer processing, which takes a long time to scan;

[0004] 2. Panoramic human body scanning system: this type of scanning system is a simple upright structure, and the height and angle range of the scanning must be adjusted manually. Model, there are defects such as unstable structure, complicated debugging, large scanning blind spots, high equipment cost, complicated post-processing, and lack of color texture in the generated 3D model;

[0005] At the same time, the current mainstream 3D scanning system is to capture the feature points of the object, the number of feature points directly affects the quality of the object; its dependence on the feature points is very serious; therefore, the feature points of the current structured light scanners are all There are very strict feature point coordinate information; however, based on the image information captured by the camera, the system that finally restores the three-dimensional information from the two-dimensional information can only meet the high-quality object data restoration by continuously improving the pixels of the camera in the system. ; The pixels of the cameras used in this type of system have reached the level of SLR cameras, but the lens prices of entry-level SLR cameras range from 3,000 yuan to 5,000 yuan, and the cost is very high
