Description
Technical field
The present invention relates to a kind of commercial measurement device more particularly to a kind of dimension measuring devices.
Background technique
It is all single area array cameras to measure the size of object that existing industrial camera, which measures size mostly, before measuring
Measuring targets are wanted position in all directions with multi-angle, measurement process is cumbersome, and cannot carry out to the object arbitrarily placed
The accurate measurement of size, especially existing industrially higher and higher to the measurement accuracy requirement of object, single camera is inaccurate because positioning
Really, larger so as to cause the dimension data error measured.
Summary of the invention
The purpose of the present invention is to provide a kind of dimension measuring devices, and it is right before measuring to solve existing industrial camera
Object under test position in all directions with multi-angle, and measurement process is cumbersome, and cannot carry out size to the object arbitrarily placed
Accurate measurement, especially it is existing industrially the measurement accuracy of object is required it is higher and higher, single camera because of position inaccurate, from
And the problem for causing the dimension data error measured larger.
The invention is realized in this way it includes line-scan digital camera, camera lens, illuminator, HIROSE connector, body to be measured, biography
Send band, power outlet, light source controller, motor, electric machine controller, computer, it is characterised in that: described two line-scan digital cameras are mutual
Vertically, the line-scan digital camera lower end is equipped with camera lens, and the line-scan digital camera connects computer, the linear array phase by HIROSE connector
Machine connects power outlet, and the line-scan digital camera is arranged right below body to be measured, and conveyer belt is equipped with below the body to be measured, described to be measured
Body two sides are equipped with illuminator, and the illuminator connects light source controller, and the conveyer belt, motor and electric machine controller successively connect
It connects.
The body to be measured is cylindrical body.
The computer passes throughWithIt obtains
The solution have the advantages that: the cylindrical body to be measured for the unspecified angle that the present invention places on a moving belt is not required to pair
Body to be measured carry out in all directions, multi-angle positioning, the data of both direction are measured by line-scan digital camera, the standard of you can get it body to be measured
True diameter dimension, easy to operate and measurement data are accurate.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 measures size figure for body to be measured of the invention.
In the figure 1, line-scan digital camera 2, camera lens 3, illuminator 4, HIROSE connector 5, body to be measured 6, conveyer belt 7,
Power outlet 8, light source controller 9, motor 10, electric machine controller 11, computer.
Specific embodiment
The present invention is illustrated in conjunction with Fig. 1,2, described two line-scan digital cameras 1 are mutually perpendicular to, 1 lower end of line-scan digital camera
Equipped with camera lens 2, the line-scan digital camera 1 connects computer 11 by HIROSE connector 4, and the line-scan digital camera 1 connects power outlet
7, the line-scan digital camera 1 is arranged right below body 5 to be measured, is equipped with conveyer belt 6 below the body 5 to be measured, 5 two sides of body to be measured are set
There is illuminator 3, the illuminator 3 connects light source controller 8, and the conveyer belt 4, motor 9 and electric machine controller 10 are sequentially connected.
The body to be measured 5 is cylindrical body.
It when measurement, focuses first to two line-scan digital cameras 1 in left and right, fixes line-scan digital camera 1 later and arrive certain altitude, directly
Until occurring clearly image into computer 11, then the frame number of two line-scan digital cameras 1 is carried out on computer 11 as needed
Setting, two illuminators 3 are symmetrically distributed in the left and right sides of body 5 to be measured, and light source controller 8 connects illuminator 3, by adjusting light
Switch button on source controller 8 opens and closes illuminator 3, by adjusting the light intensity button on light source controller 8, comes
The light intensity and color of illuminator 3 are adjusted, so that until line-scan digital camera 1 takes high-visible image, the electric machine controller
10 control 5 movement velocity of body to be measured on conveyer belt 6 and conveyer belt 6, the transmission of conveyer belt 6 by adjusting the revolving speed of motor 9
The frame number of speed and line-scan digital camera 1 is adapted, i.e., body 5 to be measured is transmitted to 2 lower section of camera lens, and two line-scan digital cameras 1 in left and right are just clapped
Take the photograph that clearly the image information of the body to be measured 5 taken is passed sequentially through line-scan digital camera 1 and HIROSE by picture, camera lens 2 to a width
Connector 4 passes to computer 11.
As shown in Fig. 2, d0For the true diameter of body 5 to be measured, α is the deviation angle of opposite 1 vertical plane of line-scan digital camera of body 5 to be measured
Degree, d1For the size that left side line-scan digital camera 1 detects, d2For the size that right side line-scan digital camera 1 detects, the two linear array phases in left and right
The size d that machine 1 detects camera lens 21And d2Computer 11 is inputted by HIROSE connector 4, computer 11 is soft by PHOTOSHOP
Part automatic measurement goes out d1And d2, then formulaWithIt inputs in EXCEL, utilizes
Excel included computing function calculates separately out α and d0, obtain the actual size d of body 5 to be measured0。
Embodiment described above only describe the preferred embodiments of the invention, not to model of the invention
It encloses and is defined, without departing from the spirit of the design of the present invention, those of ordinary skill in the art are to technical side of the invention
The various changes and improvements that case is made should all be fallen into the protection scope that claims of the present invention determines.
