Breath needs mobile laser and camera continuous acquisition elevation information to shape to obtain object in the location information of three-dimensional space
At the 3D shape of body surface.Concrete mode is use vertical six-joint robot progress 3D laser measurement, and 3D laser measurement
Device is mounted in robot, is scanned to obtain the 3D number of body surface with the movement of 3D laser measurer by robot
According to.Walking precision, the run trace, Yi Jihang of vertical six-joint robot are relied on when obtaining the 3D data of body surface in this way
Speed is walked, therefore higher to the run trace precision and rate request of six-joint robot, and because there is accuracy error, and is implemented as
This is also higher, thus it is necessary to the structures for 3D laser data acquisition system to be studied and be improved.
Utility model content
One of the purpose of this utility model is in view of the above deficiencies, to provide a kind of 3D laser data acquisition system, to
Hope solve in the prior art body surface three-dimensional form scan and measurement need to rely on six-joint robot, it is higher to required precision and
Easily there are deviation, the technical problems such as implementation cost height.
In order to solve the above technical problems, the utility model uses following technical scheme：
A kind of 3D laser data acquisition system provided by the utility model, including ccd sensor and laser emitter, institute
Laser emitter is stated to be mounted on rotational motion mechanism, end and the driving device of rotational motion mechanism are connected by power, for by
Rotational motion mechanism is around own axis, so that laser emitter be driven move in the range of 180-360 degree, CCD is passed
Sensor and laser emitter distinguish access controller, and the acquisition of the output position of the ccd sensor and ccd sensor
Position is corresponding with platform to be measured.
Preferably, further technical solution is：The rotational motion mechanism is in the shape of cylinder column, described to swash
Optical transmitting set is mounted in the radial position of rotational motion mechanism.
Further technical solution is：The installation site of the acquisition camera lens of the ccd sensor and the platform to be measured
It is perpendicular.
Compared with prior art, the beneficial effects of the utility model first is that：It is driven and is swashed by rotational motion mechanism rotation
Optical transmitting set rotation, is scanned, without making so that laser emitter be made to emit laser measuring targets in the course of rotation
It can be obtained higher precision with laser emitter movement with six-joint robot, but also it is more stable when laser scanning, fastly
Speed obtains the 3D data of 3D body surface, and for six-joint robot, implementation cost is lower, while the utility model is mentioned
A kind of 3D laser data acquisition system structure supplied is simple, and it is wide to be suitable for middle use, application range in all kinds of places.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for illustrating the utility model one embodiment；
In figure, 1 it is ccd sensor, 2 is laser emitter, 3 is rotational motion mechanism, 4 is controller, 5 is to be measured flat

Sensor 1 and laser emitter 2, ccd image sensor CCD above-mentioned（Charge Coupled Device）, it
It is made using a kind of semiconductor material of high sensitivity, light can be transformed into charge, be converted by analog-digital converter chip
Digital signal, digital signal are saved after overcompression by the flash memory of camera internal or built-in hard disk card, thus can be with
Data are easily transferred to computer, and by means of the processing means of computer, as needed and imagination is to modify figure
Picture.
Above-mentioned laser emitter 2 is mounted on rotational motion mechanism 3, and the end of the rotational motion mechanism 3 and drive
Dynamic device is connected by power, and is used for by rotational motion mechanism 3 around own axis, so that laser emitter 2 be driven to carry out 180-
It is moved in the range of 360 degree, and ccd sensor 1 and laser emitter 2 distinguish access controller 4, and ccd sensor 1
The acquisition position of output position and ccd sensor 1 is corresponding with platform 5 to be measured.Laser emitter is controlled by controller 4
2 startings, and drive laser emitter 2 to rotate by rotational motion mechanism 3, then controller 4 controls ccd sensor 1 and starts, at this time
Projection of the laser rays on camera ccd sensor, to get 3 dimension shapes of body surface.
In the present embodiment, being rotated by rotational motion mechanism 3 drives laser emitter 2 to rotate, to make Laser emission
Device 2 emits laser measuring targets 6 in the course of rotation and is scanned, without using six-joint robot with laser emitter
2 movements can be obtained higher precision, but also it is more stable when laser scanning, the 3D data of 3D body surface are quickly obtained,
