Abstract
The invention relates to a positioning device and method for correcting camera parallelism and distance. The positioning device comprises a fixing rack and a tripod which are opposite to each other. The fixing rack is provided with a shooting plane. A laser emitter is vertically arranged on the shooting plane. A clamp seat which can rotate 360 degrees is arranged on the tripod. The clamp seat is used for mounting a camera to allow the camera and the laser emitter to be located on the same straight line and allow the light beam emitted by the laser emitter to coincide with the light beam reflected by the lens of the camera. A measuring scale is arranged between the fixing rack and the tripod. By the positioning device, the parallelism and distance between the camera and the shooting plane can be corrected fast.

Background technology
In the measurement survey field of photographic head, need in some cases to keep the photographic head situation to camera plane perfect parallelism, the performance of performance or photographic head scanning barcode to test photographic head.General method is that the angle of photographic head is subjectively debugged by employing ocular estimate or photographic head is corrected by the vertical angle of availability gage, but the precision that these methods are corrected is not high so that the resultant error measured is bigger.If adopting the moulds of industrial equipment more complicated than higher-end that photographic head and camera plane are kept the situation of perfect parallelism, then need to put into more cost factor.
On the other hand, some for scanning, the photographic head of digital product that shoots be not rule be parallel or vertical angle with outer rim, the depth of parallelism keeping photographic head and camera plane is brought certain difficulty by this.Therefore, it is the object that the present invention studies for the problems referred to above.
Summary of the invention
The present invention is directed to above-mentioned prior art Problems existing and make improvement, namely the technical problem to be solved is to provide a kind of positioner correcting the photographic head depth of parallelism and distance and method thereof, contributes to solving the problem that time camera plane is needed to keep perfect parallelism by photographic head in the shooting of current photographic head, sweep test process, precision is not high, cost is bigger.
In order to solve above-mentioned technical problem, a kind of technical scheme of the present invention is: a kind of positioner correcting the photographic head depth of parallelism and distance, including the fixed mount being oppositely arranged and tripod, described fixed mount is provided with camera plane, described camera plane is vertically installed with laser beam emitting head, described tripod is provided with can 360 ° rotate decks, this deck is used for installing photographic head, so that photographic head and laser beam emitting head are located along the same line, the reflection light beam launching light beam and photographic head eyeglass of laser beam emitting head overlaps, it is provided with measuring rule between described fixed mount and tripod.
Further, the specular reflection film of a high reflectance for being attached on photographic head eyeglass is also included.
Measuring rule further, also includes one for the clamp fixture of degree of fixation gage, so that can be dismantled in this clamp fixture and mobile.
Further, described tripod is liftable tripod.
In order to solve above-mentioned technical problem, a kind of technical scheme of the present invention is: a kind of localization method correcting the photographic head depth of parallelism and distance, sequentially includes the following steps:
(1) camera plane is arranged on a fixed mount, and in camera plane, is vertically arranged a laser beam emitting head, be relatively fixed frame and one tripod is set, and a measuring rule is set between fixed mount and tripod；
(2) being arranged on tripod by photographic head, the distance of photographic head Yu camera plane is accurately adjusted by availability gage；
(3) open laser beam emitting head and launch light beam, light beam is to be perpendicular to the angular emission of camera plane to photographic head eyeglass, photographic head lens reflecting returns this light beam, and the angular deviation of photographic head is finely corrected, and makes the reflection light beam launching light beam and photographic head eyeglass of laser beam emitting head overlap.
Further, described photographic head eyeglass is pasted with the specular reflection film of high reflectance.
Measuring rule further, also includes one for the clamp fixture of degree of fixation gage, so that can be dismantled in this clamp fixture and mobile.
Further, described tripod is liftable tripod.
Compared with prior art, the method have the advantages that present configuration is simple, easy to operate, just can meet the situation of high-precision maintenance camera plane and photographic head perfect parallelism when only increasing little cost.Greatly reduce the error in data in photographic head shooting, sweep test process.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Accompanying drawing explanation
Fig. 1 is that in the embodiment of the present invention, photographic head does not correct upwards inclined organigram.
Fig. 2 is that in the embodiment of the present invention, photographic head does not correct the organigram to lateral deviation.
Fig. 3 is the organigram that in the embodiment of the present invention, photographic head is corrected.
In figure: 1-fixed mount, 2-camera plane, 3-laser beam emitting head, 4-tripod, 5-photographic head, 6-measuring rule, 61-clamp fixture, 7-launches light beam, and 8-reflects light beam, 9-overlapping beams.
Detailed description of the invention
Embodiment one: as shown in Fig. 1 ~ 3, a kind of positioner correcting the photographic head depth of parallelism and distance, including the fixed mount 1 being oppositely arranged and tripod 4, described fixed mount 1 is provided with camera plane 2, described camera plane 2 is vertically installed with laser beam emitting head 3, described tripod 4 is provided with can 360 ° rotate decks, this deck is used for installing photographic head 5, so that photographic head 5 and laser beam emitting head 3 are located along the same line, the reflection light beam 8 launching light beam 7 and photographic head eyeglass of laser beam emitting head overlaps, and is provided with measuring rule 6 between described fixed mount and tripod.
In the present embodiment, for protecting the sensor devices within photographic head, also include the specular reflection film of a high reflectance for being attached on photographic head eyeglass.
In the present embodiment, in order to adjust further accurately the distance of photographic head and camera plane, also include one for the clamp fixture 61 of degree of fixation gage, so that measuring rule can dismantle in this clamp fixture and moves.
In the present embodiment, described tripod is liftable tripod.
Said apparatus uses according to the following steps:
(1) camera plane is arranged on a fixed mount, and in camera plane, is vertically arranged a laser beam emitting head, be relatively fixed frame and one tripod is set, and a measuring rule is set between fixed mount and tripod；
(2) photographic head is arranged on tripod, open laser beam emitting head and launch light beam, light beam is to be perpendicular to the angular emission of camera plane to photographic head eyeglass, photographic head lens reflecting returns this light beam, the angular deviation of photographic head is finely corrected, makes the reflection light beam launching light beam and photographic head eyeglass of laser beam emitting head overlap；
(3) distance of photographic head Yu camera plane is accurately adjusted by availability gage.
If photographic head occurs above lower angle to tilt (such as Fig. 1), then reflection light beam substantially forms angle with transmitting light beam, and deviation is more big, and upper and lower angle is more big；If left and right angle inclination (such as 2) occurs photographic head, then reflection light beam substantially and launches light beam formation angle, and deviation is more big, and left and right angle is more big；Correct photographic head angle, be completely superposed into overlapping beams 9(such as 3 until launching light beam with reflection light beam), then reach the purpose correcting photographic head with camera plane maintenance perfect parallelism.
