Abstract
The present invention relates to a kind of optical grating projection formula object surface appearance measurement apparatus that can adjust measurement angle, the device is made up of horizon bar, stepper motor, rotary shaft, CCD camera, projecting apparatus, the measurement apparatus can adjust measurement angle, in the complicated curved body part of measurement, without the artificial position for changing CCD camera and projecting apparatus, so as to improve measurement efficiency and obtain clearly raster image.
Description
Technical field
The present invention relates to three-dimensional measurement technical field, and in particular to a kind of optical grating projection formula thing that can adjust measurement angle
Body surface figure measuring device.
Background technology
In modern surveying, measuring three-dimensional morphology is either daily in industry manufacture, biomedical, historical relic's protection and people
In life, irreplaceable effect is all played, and it is higher to find precision, the faster 3 D measuring method of speed is also increasingly
As the most important thing of this area research.At present, optical three-dimensional measurement technology is because with high accuracy, and testee is non-connects
The advantages of touching is so as to being rapidly progressed.And the measuring three-dimensional morphology technology based on optical grating projection is due to measurement of full field,
The advantages that precision is high, and cost is relatively low, it is increasingly becoming the key areas of the continuous research and probe of people.At present, many optical grating projection formulas
Object surface appearance measurement apparatus is all that CCD camera and projecting apparatus are fixed on into a certain position, when the curved body zero that measurement is complicated
The raster image collected during part is affected.Therefore, a kind of measurement dress that can adjust CCD camera and projector angles is studied
Put significant.
The content of the invention
The purpose of the present invention is：It is proposed a kind of object surface appearance measurement that can adjust CCD camera and projector angles
Device, in the complicated curved body part of measurement, without the artificial position for changing CCD camera and projecting apparatus, so as to improve measurement
Efficiency and obtain clearly raster image.
To realize the purpose of the present invention, it is achieved using following technical scheme：Horizon bar lower end is connected to left pillar, right
Pillar and connecting rod, connecting rod are connected with stepper motor, and stepper motor is connected with stepper motor driver, has on step motor shaft
Motor side gear, rotary shaft connect with left pillar with right pillar, and rotary shaft one end is connected with rotary shaft gear, is welded among rotary shaft
Two sleeves are connected to, the rotary shaft other end is provided with nut, and rotary shaft gear and the engagement of motor side gear, two sleeves connect respectively
Then CCD camera and projecting apparatus.When stepper motor driver Driving Stepping Motor works, motor side gear drives power transmission shaft tooth
Wheel rotation is so that drive axis, power transmission shaft drive the CCD camera being fixed on sleeve to be rotated with projecting apparatus.
Compared with prior art, the invention has the advantages that because rotary shaft can drive CCD camera and projecting apparatus
Rotation, when the complicated curved body part of measurement, measurement angle can be adjusted, without artificial CCD camera and the projecting apparatus of changing
Position, so as to improve measurement efficiency and obtain clearly raster image.
