Characteristic point supplement system used for multi-view geometric three-dimensional reconstruction

Abstract

The invention discloses a characteristic point supplement system used for multi-view geometric three-dimensional reconstruction. The characteristic point supplement system comprises a plurality of image acquisition processing units, which are embedded type micro-acquisition processing units formed by image acquisition units and image processing units, and are connected with a computer; a frame assembly, which is used for installation of a camera, and is provided with an LED light supplement lamp used for irradiating light on to-be-scanned targets and a characteristic point supplement lamp; The characteristic point supplement lamp is electrically connected with a switch terminal. The plurality of image acquisition processing units are connected together by switches. The computer is connected with all of the image acquisition processing units by a router in a concentrated manner. The characteristic point supplement lamp is an image projection lamp used for projecting random two-dimensional patterns, or an infrared projection lamp used for projecting infrared light patterns, or a laser projection lamp used for projecting laser interference patterns.

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; it includes multiple cameras. Background technique [0002] At present, the following 3D scanning devices are widely used in the market: [0003] 1. Hand-held scanner: This type of scanner requires the human body to keep still, scan it layer by layer according to 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; [00...

Problems solved by technology

[0003] 1. Hand-held scanner: This type of scanner requires the human body to keep still, scan it layer by layer according to 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] We have formed a set of image acquisition and restoration system for the target to be scanned based on the principle of human visual difference; the visual difference means that our system has multiple cameras, and at least two cameras will shoot at every position of the target to be scanned at the same time Image collection; the system based on this principle has high imaging restoration efficiency and good quality; however, in order to ensure high-quality information collection, the pixels of the camera used in the current system have reached the level of a SLR camera, but the entry-level SLR camera The price of the lens ranges from 3,000 yuan to 5,000 yuan, and the cost is very high
