Description

A kind of human body three-dimensional scan rebuilding device

Technical field

The utility model relates to three-dimensional reconstruction field, particularly relates to the device of human body three-dimensional scanning.

Background technology

Computer Three-dimensional reproduction technology can be converted into digital model by the object in reality, so that follow-up further research and processing.Three-dimensional (3 D) manikin has a very wide range of applications in fields such as cartoon making, dress designing, industry.At present, known human body three-dimensional method for reconstructing is mainly by structured light, Laser Scanning Equipment, by the three-dimensional information digitizing of human body.But, in said method, laser scanner belongs to non-contact optical surveying instrument, laser (often adopting lower powered visible ray laser, as He-Ne Lasers, semiconductor laser) is injected to scanner and form laser beam, and initiatively project body surface, the signal of accepted thing surface reflection is measured, this instrument is conventionally bulky, need build complicated support, and laser also has certain harm to user of service's eyes; The structured light that structured light scanner (for example ATOS spatial digitizer of German GOM company) is counted width specific coding by the projection of optical grating projection device is to object under test surface, two cameras that form an angle are synchronously adopted to obtain respective image, then image is decoded and phase calculation, obtain the three-dimensional coordinate of body surface point, it is subject to ambient light effects larger, limited by color of object surface, can not measure black object and reflective object.Before use, two kinds of scanning devices all need to demarcate, once setting position moves, need again to demarcate.In addition structured light and laser equipment are expensive, require high to user of service's functipnal capability.The scanning system of existing minority based on Kinect depth camera, needs the situation such as three-dimensional model rough surface of post-processed and generation but also exist device complexity, scanning result, and due to the impact of device and post-processed, the speed of scan rebuilding is slower.

Summary of the invention

In order to overcome the deficiency of existing human body three-dimensional method for reconstructing apparatus expensive, complicated operation, the utility model provides a kind of human body three-dimensional scan rebuilding device.

The utility model solves the technical scheme that its technical matters adopts:

The utility model comprises two of Kinect depth cameras, fixed bar, electric platform, computing machine and usb data line; Described fixed bar vertically arranges with respect to ground; Described two Kinect depth cameras are separately fixed at two places up and down of fixed bar and are connected with computing machine by usb data line; Described electric platform is arranged on a side of fixed bar, and described two Kinect depth camera camera lenses are towards electric platform.

Described two Kinect depth cameras on fixed bar height overhead that is fixed on is respectively 0.3～0.8m and 1.2～1.6m, and the center of described electric platform is 1.2～1.8m from the distance of fixed bar.

Described two Kinect depth cameras on fixed bar height overhead that is fixed on is respectively 0.5m and 1.4m, and the center of described electric platform is 1.5m from the distance of fixed bar.

In the utility model, 2 Kinect depth cameras are fixed on height on fixed bar can be according to treating that people's height that 3-D scanning is rebuild adjust, and the distance between electric platform and fixed bar also can be adjusted as required.Should require to set initialization system parameter according to acquisition precision, every meter of collection be counted and is chosen as 128,256,512,640 simultaneously.

It is reasonable, succinct that the utility model device forms, and method is convenient, uses the utility model can scan rapidly the complete three-dimensional data that obtains human body, and cost is low, simple to operate, easy to use.

Accompanying drawing explanation

Fig. 1 is the device schematic diagram of a kind of embodiment of the utility model, wherein 1-fixed bar, 2-Kinect depth camera, 3-Kinect depth camera, 4-electric platform, 6-computing machine, 7-USB data line, 8-USB data line.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail.

As shown in Figure 1, it comprises two Kinectdepth cameras 2,3, fixed bar 1, electric platform 4,computing machine 6 andusb data line 7,8.Fixed bar 1 vertically arranges with respect to ground; 2 Kinectdepth cameras 2 and 3 are fixed on the upper of fixed bar 1, and are connected withcomputing machine 6 with 8 byusb data line 7; Electric platform 4 is arranged on a side of fixed bar 1; 2 Kinectdepth camera 2 and 3 camera lenses are all towards electric platform 4;Computing machine 6 is provided with data acquisition processing system.Effective shooting distance of Kinect depth camera is 1.2m～3.5m.The precision of obtaining of its depth data constantly declines with the increase of shooting distance.And shooting distance is excessively near, two Kinect cameras cannot scan complete human body.The center that therefore described electric platform is preferably set is 1.2～1.8m from the distance of fixed bar.Kinect depth camera vertical direction visible angle is 43 °, the human body altitude range that separate unit Kinect depth camera vertical direction under respective distance can be taken is 0.94m～1.42m, described in be fixed on 2 Kinect depth cameras on fixed bar height overhead and be preferably set to respectively 0.3～0.8m and 1.2～1.6m.

Consider in shooting process that two Kinect depth cameras somatic data obtaining of sampling need to guarantee the overlapping of certain limit, and human body be conventionally highly no more than 1.9m, and consider the height of electric platform, more preferably be set to: described in be fixed on 2 Kinect depth cameras on fixed bar height overhead and be respectively 0.5m and 1.4m, the center of described electric platform is 1.5m from the distance of fixed bar.Now, the height that two Kinect depth cameras can scan is 2.36m, removes lap and electric platform height, and the human body maximum height that can scan is 2.0m.

The related data acquisition processing system of the utility model adopts existing software, and it forms by gathering and splicing two modules.After software startup, first systematic parameter is carried out to initialization, set the parameters such as the frequency, resolution, scanning accuracy that gather, two Kinect depth cameras come into operation simultaneously subsequently, scan respectively the upper and lower two parts of human body, generate two cloud datas up and down of human body; , first two slice some clouds carried out to the pre-service such as denoising, then utilize calibration result and iterative closest point joining method, two point clouds are spliced to (registration), finally obtain the complete point cloud data of human body thereafter.
