Abstract
The utility model discloses a bi-planar calibration plate, which comprises a main calibration plate, a subordinate calibration plate and a connecting device, and the connecting device is connected between the main calibration plate and the subordinate calibration plate. The connecting device is a hinge, one end of the connecting device is fixedly connected with the main calibration plate, and the other end of the connecting device is fixedly connected with the subordinate calibration plate. The bi-planar calibration plate is convenient to use and simple to manufacture.
Description
Technical field
The utility model relates to a kind of camera calibration plate, particularly a kind of video camera biplane scaling board that can be used for taking the augmented reality video.
Background technology
Augmented reality is meant that the scene of in video image virtual object and reality being taken merges, and reaches visual perception's effect that reality and dummy object can't be distinguished, and wherein Camera calibration is the emphasis of augmented reality technology.Utilize the 3 D stereo scaling board to obtain camera parameters in early days, but owing to each plane that requires three-dimensional scaling board must be strict vertical mutually, very difficult in the making.At present normally used is the plane reference plate, but only takes the calculating that image that single width has the plane reference plate can't be finished all variable elements of video camera, and if use midplane scaling board vertical ground to place, need other object support usually.
The utility model content
Technical problem to be solved in the utility model provides a kind of biplane scaling board.
A kind of biplane scaling board comprises main scaling board, from scaling board and coupling arrangement, and described coupling arrangement is connected main scaling board and between the scaling board.
Described biplane scaling board, described coupling arrangement are hinge, and an end of hinge is fixedlyed connected with main scaling board, the other end with fixedly connected from scaling board.
Make simply, practical and convenient, only take the calculating that image that single width has scaling board just can be finished all variable elements of video camera, scaling board can independently be placed vertically in ground in the use.
Description of drawings
Fig. 1 is that biplane scaling board vertical ground of the present utility model is placed the top view when opening;
Embodiment
Below in conjunction with specific embodiment, the utility model is elaborated.
With reference to Fig. 1, the utility model biplane scaling board comprises main scaling board 1, from scaling board 2, and principal and subordinate's scaling board coupling arrangement 3.
Below the using method of the utility model biplane scaling board is made an explanation.
When using the utility model biplane scaling board, this biplane scaling board is opened about 90 to 160 degree, be vertical or parallel to ground and place, just can take then and calibrated and calculated.
By principal and subordinate's scaling board coupling arrangement, principal and subordinate's scaling board can be integrated easily, so not only can only take image that single width has scaling board and just can finish the calculating of all variable elements of video camera, and scaling board in use can be placed by independent vertical ground, make simple, easy to carry and transport.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
Claims (2)
1. a biplane scaling board is characterized in that, comprises main scaling board, from scaling board and coupling arrangement, and described coupling arrangement is connected main scaling board and between the scaling board.
2. biplane scaling board according to claim 1 is characterized in that, described coupling arrangement is a hinge, and an end of hinge is fixedlyed connected with main scaling board, the other end with fixedly connected from scaling board.
