Industrial robot replaces the artificial degree more and more higher for carrying out automated production.The most basic application method of industrial robot is uneasy
Any sensor is filled, some actions fixed can only be carried out in fixed scene by teaching or be programmed in.With robot
Application environment and goal task become increasingly complex changeable, it is necessary to install some sensings in the environment or on robot body
Device, wherein depth camera are the very important sensors of one type.Relative to traditional 2D cameras, depth camera can be observed
To the depth information of object, it is thus possible to the position of easier determination object in space.But it is applied to by depth camera
During robot field, problems with is run into：1st, different from common 2D cameras, depth camera can not see common 2D demarcation chessboard
Lattice, thus, it can only be demarcated during demarcation using the scaling board of special spatial configuration, so that calibration process is complex；
2nd, spatial configuration scaling board is also relatively difficult in processing, and this just brings inconvenience for the application of depth camera.
Utility model content
The purpose of this utility model is a kind of depth camera caliberating device that field is captured for industrial robot of offer,
To solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides following technical scheme：
It is a kind of for industrial robot capture field depth camera caliberating device, including industrial robot, end-of-arm tooling,
Depth camera its special calibrating plate and depth camera, the end-of-arm tooling are arranged on the end of industrial robot, and depth camera is special
Scaling board is fixed on end-of-arm tooling and depth camera its special calibrating plate includes hollow out gridiron pattern and transparency glass plate, hollow out chess
Disk lattice are arranged on transparency glass plate, and depth camera is fixed on the top of workbench.
It is used as further program of the utility model：Depth camera its special calibrating plate is fixed by dismountable connection member
On end-of-arm tooling.
It is used as further program of the utility model：Transparency glass plate is made using lucite.
Compared with prior art, the beneficial effects of the utility model are：The utility model is used for industrial robot field
Depth camera caliberating device, it is simple for structure light and handy, it can just realize the depth for industrial robot field by easily installing
The Fast Calibration function of the inside and outside ginseng of camera is spent, and the robot and end-of-arm tooling of different model can be adapted to, strong applicability is fitted
Conjunction is widely used in industrial robot field.

Fig. 2 is the knot of depth camera its special calibrating plate in the depth camera caliberating device for capture field for industrial robot
Structure schematic diagram.
Wherein：1- industrial robots, 2- end-of-arm toolings, 3- depth camera its special calibrating plates, 31- hollow out gridiron patterns, 32- is saturating
Bright glass plate, 4- depth cameras.
Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Refer to Fig. 1-2, a kind of depth camera caliberating device that field is captured for industrial robot, including industrial machine
People 1, end-of-arm tooling 2, depth camera its special calibrating plate 3 and depth camera 4, the end-of-arm tooling 2 are arranged on industrial robot 1
End, depth camera its special calibrating plate 3 is fixed on end-of-arm tooling 2 and depth camera its special calibrating plate 3 includes hollow out chessboard
Lattice 31 and transparency glass plate 32, hollow out gridiron pattern 31 are arranged on transparency glass plate 32, and depth camera 4 is fixed on the upper of workbench
Side.Depth camera its special calibrating plate 3 is fixed on end-of-arm tooling 2 by dismountable connection member.Transparency glass plate 32 is used
Lucite makes.
Operation principle of the present utility model is：The workflow of the device is as follows：First, the device is placed in depth camera
Within sweep of the eye, several pictures of camera calibration plate are shot using depth camera；Second, using Robust Algorithm of Image Corner Extraction from picture
Extract X-comers；3rd, depth camera internal reference is demarcated using conventional 2D camera calibrations method, depth camera is obtained
Internal reference；4th, depth camera its special calibrating plate is fixed on the end-of-arm tooling of industrial robot, driven by robot motion
Scaling board is moved, and scaling board image is gathered by depth camera；5th, depth camera phase is calculated according to the image collected
For the outer ginseng of depth camera its special calibrating plate；6th, with reference to the terminal position of industrial robot, utilize hand and eye calibrating method mark
Determine outer ginseng of the depth camera its special calibrating plate relative to industrial robot.
Depth camera based on structure light or TOF principles, when observing tradition 2D scaling boards (plane gridiron pattern), due to
Three-dimensional feature is had no on scaling board, thus, depth camera 4 can not observe traditional 2D scaling boards, i.e., can not directly use 2D
Camera calibration plate (plane gridiron pattern) is demarcated to depth camera 4；And the depth camera its special calibrating for using this patent to propose
Plate 3, due to the translucency and the opaqueness of paper of glass, thus, the glass depth corresponding in depth camera 4 with paper
Degree information is just significantly different, and so, depth camera 4 just can clearly observe gridiron pattern information in depth map, further
, depth camera can be demarcated based on translucent depth camera its special calibrating plate described above.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
