Abstract
The utility model discloses a kind of locator structure of accurate instruction shooting center, it comprises: two independently yi word pattern laser instruments; Obtain the camera of image; Two point of crossing of light curtain in plane to be captured that independently yi word pattern laser instrument is launched are center to be captured.The utility model can indicate the image of acquisition centered by indicating positions more fast, accurately.
Description
Technical field
The utility model relates to a kind of locator structure of accurate instruction shooting center, specifically a kind of device using pair yi word pattern laser instrument accurately to indicate shooting center.
Background technology
At present, except the microlens of some professional coaxial laser instructions, the common method of the center of laser designation location shooting image is used to have a light source laser and single " cross " laser instrument; But there is following problem in these two kinds of methods:
1. pointolite, due to the center of general camera camera lens can not be arranged on, namely must tilt to install, so, even if camera lens axis is definitely orthogonal with the plane that is taken, when when camera position is movable, adjustment is focused, instruction hot spot also can change to some extent and offset, and causes the out of true of indicating positions;
2. single " cross " laser instrument, indicates similar with pointolite, still can not guarantee that the projection centre of " cross " laser instrument is exactly the center of shooting; Especially change at the shooting distance of camera, lens focus is when changing to some extent.
Utility model content
In view of this, the technical matters that the utility model solves is to provide a kind of indicating positions not change with shooting distance, lens focus and change to some extent, and accurately can indicate the locating device of the axis centre of camera lens, thus fast, the fixed point area information of effective shooting works.
For solving above technical matters, the utility model provides a kind of locating device using pair yi word pattern laser instrument accurately to indicate shooting center, and it comprises:
Two independently yi word pattern laser instruments;
Camera that be oppositely arranged with works, that obtain image.
Further, the two yi word pattern laser instrument in center, described camera site accurately indicates.
Further, the light curtain of described pair of yi word pattern laser instrument transmitting has a certain degree (being generally vertical), and camera (or camera is after movement) lens axis is comprised in two light tentorial planes of two yi word pattern laser instruments transmittings.
Further, no matter how the focal length of taking lens changes (that is: how the distance of shot object and camera changes), the projected intersection of light curtain in camera plane that twin-laser is launched is the center obtaining image.
Further, the camera obtaining image both can be the camera of the large scale image obtaining visual effect, also can be the camera obtaining small scale micro-image.
Further, two yi word pattern laser instrument can be arranged on camera lens (or lens attachments) and move with camera; Also can be separated with camera completely, namely not move with camera.
Compared with prior art, the utility model indicates the position at shooting center more accurately and fast.
Accompanying drawing explanation
Figure 1 shows that the locator structure figure at a kind of accurate instruction shooting center of the utility model embodiment one.
Figure 2 shows that the locator structure figure at a kind of accurate instruction shooting center of the utility model embodiment two.
Specific embodiments
Twin-laser is used accurately to indicate two of the locating device at shooting center embodiments to be described, to understanding the purpose of this utility model, specific structural features and advantage further below in conjunction with accompanying drawing to the utility model.
Embodiment one
Please refer to accompanying drawing 1, attachedly Figure 1 shows that the utility model uses twin-laser accurately to indicate the positioning device structure figure embodiment one at shooting center.It comprises: the yi word pattern laser instrument 11 of vertical direction; The yi word pattern laser instrument 12 of horizontal direction; Camera lens 13 that be oppositely arranged with works, that obtain work images; The yi word pattern laser instrument 12 of the laser instrument 11 of the yi word pattern of vertical direction and horizontal direction can move with camera lens 13, namely on laser instrument 11 and 12 zoom ring that is installed in camera or secondary light source.
The axis direction of camera lens shown in accompanying drawing 1 is X-axis, and O is the center of camera lens front end; YZ plane is camera lens front plan, and origin is O; Y ' Z ' is the works place plane that is taken, and Y ' is parallel with Y, and Z ' is parallel with Z, and XY ' Z ' three axle system origin is O '.The light curtain (RST) 22 that the light curtain (MNP) 21 that laser instrument 11 is launched and laser instrument 12 are launched intersects, and coincides with the ZO ' line segment on the axial line of the camera lens 13 obtaining image.O ' is the point of subject surface, then O ' is exactly the center of shooting image.
The light curtain 21,22 launched by two yi word pattern laser instrument 11,12 intersects on the axial line (X-axis) of the camera 13 obtaining image, accurately indicates the center that namely shaft core position of camera lens 13 is taken.Camera lens keep its axial line constant movable time (only moving along X-axis), accurately can obtain the image information of assigned address efficiently.
Embodiment two
Please refer to accompanying drawing 2, attachedly Figure 2 shows that the utility model uses two yi word pattern laser accurately to locate the structure drawing of device embodiment two at shooting center.Identical with embodiment one is that its basic structure comprises horizontal laser 11, vertical laser 12 and camera lens 13; Be separated with camera lens 13 unlike two laser instruments 11,12 with embodiment one, two laser instruments 11,12 are not followed camera lens 13 and are moved.
O shown in accompanying drawing 2 is any point in works plane; XYZ coordinate system initial point is O point; Laser instrument 12 is fixing and the light curtain (RST) 22 launched hands over X-axis in S, T point; Laser instrument 11 can move along being parallel to X-direction, and its light curtain (MPN) 21 launched intersects Y in P, N point; The image device center that O ' is camera lens 13, Y and Y ', Y " parallel, X and X ' is parallel, Z and Z ' parallel.It can be any point in X-axis that the light curtain (MPN) 21 that laser instrument 11 is launched and the light curtain (RST) 22 that laser instrument 12 is launched intersect at intersection point X-axis being put O(two faces, be illustrated as 3 axle initial point O points herein), O is the point of subject surface, then O is exactly the center of shooting.According to the instruction of laser instrument 11,12 point of crossing O, camera lens 13 is moved to this position along X-axis, the image of position centered by O point can be obtained.
Use this apparatus structure, the light curtain 21,22 launched by two yi word pattern laser instrument 11,12 intersects at the arbitrfary point on shooting works, accurately location mobile camera lens 13 navigates to this indicating positions, accurately can obtain the image centered by indicating positions.
