Abstract
The utility model relates to a foot type calibration template, being a transparent organic glass slab. The foot type calibration template is provided with a plurality of rows and a plurality of lines of graticules separated by certain intervals, and the center of the foot type calibration template is provided with a center logo. The periphery of the center mark is also provided with an azimuth logo group, and the center logo can be used as the origin of a three-dimensional coordinate system to provide a reference point for computer three-dimensional reconstruction software. The images of the cross points of the graticules separated by certain intervals in cameras can figure out the position of the cameras, so the calibration problem of the cameras is solved. The foot type calibration template is the transparent organic glass slab, and the image collection of the cameras under the organic glass slab is not influenced. When the image of the foot type bottom part is collected, the foot type calibration template does not need to be withdrawn. The foot type calibration template has firm structure and can be used as a foot type bearing platform.
Description
Technical field
The utility model relates to a kind of calibrating template, particularly at the calibrating template of pin type.
Background technology
Object being carried out demarcate in the process of three-dimensional reconstruction is a very important step, scaling method of the prior art need be placed the object (being called calibrated reference) of a known form and size before camera, calculate the position of camera, take away calibrated reference then, again the object that needs three-dimensional reconstruction is taken pictures, carry out three-dimensional reconstruction by the corresponding relation between spatial point and the picture point, Zhang Zhengyou as Microsoft Research adopts two to three mutually orthogonal planes to form calibrating template, because simple and practical being widely accepted, but the method for Zhang Zhengyou needs earlier the calibrated reference imaging, take away calibrated reference then once more to object image-forming, need be divided into two steps demarcating imaging and reestablishment imaging, and, can not be applicable to that many apparent weights of multi-faceted imaging of full week are built owing to adopted opaque calibrating template; Research object of the present invention is a pin, pin need be placed on a certain supporter, and supporter must influence the IMAQ of sole portion, and the scaling method of Zhang Zhengyou can not use.If with the unsettled imaging of pin, certainly exist the inconsistent problem of different object placement locations, influence imaging effect.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of have suitable pin type three-dimensional reconstruction, simple in structure, calibration process simple, having can the heavy pin type calibrating template of carrying leg.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of pin type calibrating template, it is characterized in that pin type calibrating template is transparent poly (methyl methacrylate) plate, have multiple lines and multiple rows and phase graticule across a certain distance on the described pin type calibrating template, described pin type calibrating template center is provided with the center sign, and sign periphery, described center also is provided with the bearing mark group.
As a kind of improvement, described graticule is orthogonal co-ordination, described center is designated the stack body of " O " word and " ten " word, described bearing mark group is at least three groups of different pattern, described bearing mark group is positioned on the different levels with respect to the center sign, described every stack orientations identified group is roughly equally distributed four patterns on same level, the stack body of " O " word and " ten " word has made things convenient for the foundation of determining of the origin of coordinates and coordinate system, at least three groups and four patterns that are positioned on the different levels can be determined the orientation, and after when the pin type covers the part bearing mark still can easily the identification orientation, reduce the amount of calculation of three-dimensional reconstruction.
The utility model pin type calibrating template is provided with the center sign, can be as the initial point of three-dimensional system of coordinate, for calculating, computerized three-dimensional reconstruction provides reference point, mutually its crosspoint of graticule across a certain distance can calculate the position of each camera in each magazine imaging, has solved the demarcation problem of camera; Pin type calibrating template is transparent poly (methyl methacrylate) plate, does not influence poly (methyl methacrylate) plate below camera and gathers image, need not to remove the image that pin type calibrating template is gathered pin type bottom; Sound construction can be as the carrying platform of pin type.
The utility model will be further described below in conjunction with the drawings and specific embodiments.
