Abstract
A calibration board fixture capable of being freely twisted belongs to the field of calibration board posture positioning devices for camera calibration. The calibration board fixture comprises a base, a metal calibration tube and a wide opening spring clamp, wherein a first calibration tube mounting connector is arranged on the upper end surface of the base; a second calibration tube mounting connector is arranged on one clamping plate external end surface of the wide opening spring clamp; one end of the metal calibration tube is fixedly connected with the base via the first calibration tube mounting connector, and the other end of the metal calibration tube is fixedly connected with the wide opening spring clamp via the second calibration tube mounting connector; one rubber anti-sliding block is arranged at the front end of each of the two clamping plates of the wide opening spring clamp; the two rubber anti-sliding blocks are symmetrically placed. The calibration board fixture is simple and convenient to operate, safe and reliable, can quickly change and regulate the position and angle of the calibration plate by utilizing the twisting positioning function of the metal calibration tube, and enables the calibration board to be positioned in any expectant posture. Moreover, the calibration board fixture capable of being freely twisted has the advantages that the structure is simple and practical, the cost is lower, the popularization is facilitated, and the like.
Description
Technical field
The utility model belongs to camera calibration with scaling board gesture positioning device field, is specifically related to a kind of scaling board fixture that can FREE TORSION.
Background technology
Scaling board (Calibration Target) is widely used in the demarcation of camera, in the application process of vision measurement technology, in order to obtain desirable camera calibration model external parameter, sometimes need conversion and adjust scaling board attitude to obtain the scaling board photo at some special visual angles.Traditional scaling board attitude is controlled, and mostly is hand-held mode, because the shake of hand can cause shooting quality to decline, thus the precision that impact is demarcated.The special fixture of still not adjusting for scaling board attitude now.
Utility model content
In order to solve hand-held scaling board, adjust attitude inconvenience in taking, and easily occur shake, the technical problem of the special fixture of still not adjusting for scaling board attitude at present, the utility model provides a kind of scaling board fixture that can FREE TORSION.
The technical scheme that the utility model technical solution problem is taked is as follows:
Scaling board fixture that can FREE TORSION comprises base, metal calibration tube and wide mouthful of spring clip, and the upper surface of base is provided with the first calibration tube erection joint; A clamping plate outer face of wide mouthful of spring clip is provided with the second calibration tube erection joint; One end of described metal calibration tube is connected by the first calibration tube erection joint and base, and the other end is connected by the second calibration tube erection joint and wide mouthful of spring clip; The front end of two clamping plate of described wide mouthful of spring clip is respectively equipped with a rubber antiskid piece, two symmetrical placements of rubber antiskid piece.
The beneficial effects of the utility model are: the scaling board fixture that this can FREE TORSION is by the packaged folder scaling board of rubber antiskid on wide mouthful of spring clip, and it is simple and efficient to handle, safe and reliable.Utilize the torsion positioning function of metal calibration tube in arbitrary orientation and angle, this scaling board fixture energy Fast transforms and adjustment scaling board position and angle, make under its attitude that is positioned at any expection.In addition the scaling board fixture that this can FREE TORSION also has simple and practical, with low cost, the advantage such as is convenient to popularize.
Accompanying drawing explanation
Fig. 1 is the stereogram of the scaling board fixture that the utility model can FREE TORSION;
Fig. 2 is the application drawing of the scaling board fixture that the utility model can FREE TORSION.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 1 to Figure 2, scaling board fixture that can FREE TORSION of the present utility model comprises base 1, metal calibration tube 2 and wide mouthful of spring clip 3, and the upper surface of base 1 is provided with the first calibration tube erection joint 1-1.A clamping plate 3-1 outer face of wide mouthful of spring clip 3 is provided with the second calibration tube erection joint 3-3.One end of metal calibration tube 2 is connected by the first calibration tube erection joint 1-1 and base 1, and the other end is connected by the second calibration tube erection joint 3-3 and wide mouthful of spring clip 3.The front end of 3 two clamping plate 3-1 of wide mouthful of spring clip is respectively equipped with a rubber antiskid piece 3-2, two symmetrical placements of rubber antiskid piece 3-2.
During concrete application scaling board fixture that can FREE TORSION of the present utility model, base 1 is positioned on horizontal plane, with pointing, presses the end of two clamping plate 3-1 simultaneously and its front end is opened.Rubber antiskid piece 3-2 on two clamping plate 3-1 is placed in respectively scaling board edge both sides and alignd with the tail end sideline of rubber antiskid piece 3-2 in the sideline of scaling board.Unclamp finger, the front and rear surfaces of two clamping plate 3-1 Automatic-clamping scaling board under the reseting elasticity effect of spring of wide mouthful of spring clip 3, now, the apparent surface of two rubber antiskid piece 3-2 is parallel to each other.
When operator need to convert and adjust scaling board attitude, hold scaling board on the other hand, another hand directly reverses metal calibration tube 2, makes wide mouthful of spring clip 3 together with scaling board, arrive angle and the position of expection, can complete the attitude adjustment process of scaling board.
