Abstract
The invention discloses a system for triggering image measurement at continuous positions in motion. The system comprises a marble pedestal, an XY motion working platform, a high-precision servo rotary working platform, a high-speed image acquiring device and a motion control device. The motion control device gives out a signal to trigger the high-speed image acquiring device to acquire an image of a measured position after controlling the XY motion working platform and the high-precision servo rotary working platform to move in an interpolation manner to the measured position. Then, an upper computer processes the image to acquire needed measurement dimensions. The acquisition of images of measured positions is continuous in the process, that is to say, a moving system still moves to a next measured position during image acquiring. The system for triggering image measurement at continuous positions in motion changes a measuring manner of static image acquisition in traditional image measurement, the degree of automation is higher, and the work efficiency is improved greatly.
Description
Technical field
The invention belongs to the radiographic measurement technical field, particularly for a kind of under measured object is in moving situation, but continuous trigger radiographic measurement equipment carries out the system that assigned address is measured.
Background technology
The radiographic measurement technology is take the comprehensive measuring technique of optical, mechanical and electronic integration as the basis.The use of this technology becomes a reality extensive, contactless precision measurement, along with the continuous progress of science and technology, be accompanied by that manufacturing process becomes more meticulous and the requirement that product is measured efficient is improved constantly, again because batch production quantity is increasing, the amount of size that requires to check gets more and more, and traditional static capture metering system has not satisfied the detection measurement to the requirement of efficient.
Based on above deficiency, the present invention proposes a kind of at the volley continuous position and triggers image measuring system, and this system has been applied in the actual detection measurement, and has improved greatly the efficient of Quality Detection, save cost, remedied radiographic measurement in the low defective of practical application production capacity.
Summary of the invention
Provided by the present invention is that a kind of at the volley continuous position triggers image measuring system, technical matters to be solved is accurately to control the movement locus of XY motion workbench and high-precision servo rotary table, and can send trigger pip in the position of setting, make image capturing equipment immediately obtain the measured object image of this position, and in capture kinematic system still among the motion of next measured position point.
For realizing above-mentioned technical requirement, the present invention has adopted following technical scheme: a kind of at the volley continuous position triggers image measuring system, comprises that a marble pedestal, XY motion workbench, high-precision servo rotary table, high-speed image obtain equipment and motion control apparatus.This motion control device obtains instruction from host computer, XY motion workbench and high-precision servo rotary table are carried out closed-loop control, and after XY motion workbench and high-precision servo rotary table move to measured position point, motion control device can feed back a trigger pip to be removed to trigger image capturing equipment and carries out capture, then by host computer image is processed, obtained required measurement size.
A kind of at the volley continuous position triggers image measuring system, and its implementation comprises following essential step: measured position point all is to set take the set mechanical zero of image measuring system itself as reference point.
The present invention has improved traditional image measuring system and has necessarily required measured object and image capturing equipment to be in this restriction under the relative static conditions when detecting, and has promoted greatly measurement efficient, and has made operation simpler, quicker.
Description of drawings
Be described in further detail below in conjunction with accompanying drawing and concrete using method.

Embodiment
Please refer to Fig. 1, better embodiment when a kind of at the volley continuous position of the present invention triggers image measuring system for measurement one measured workpiece is obtained equipment 14 comprising marble pedestal 11, XY motion workbench 12, high-precision servo rotary table 13, high-speed image.
This marble pedestal 11 is placed on the horizontal table top, this XY motion workbench 12 is arranged on this marble pedestal 11 tops, this high-precision servo rotary table 13 is installed on this XY motion workbench 12, and this high-speed image obtains equipment 14 and is fixed on these marble pedestal 11 sides along the top by column.By motion control apparatus control, this XY motion workbench can carry out the interpolation linear movement along X, Y-direction simultaneously, and this high-precision servo rotary table 13 carries out the circumference motion under motion control apparatus control simultaneously.
Please refer to Fig. 2, a kind of at the volley continuous position of the present invention triggers the control method of image measuring system
May further comprise the steps:
S1: host computer links to each other with motion control apparatus, and sends instruction to motion control apparatus.
S2: motion control apparatus receives the movement instruction that host computer sends over, and control XY motion workbench and high-precision servo rotary table are according to the movement locus motion that sets.
S3:XY motion workbench and high-precision servo rotary table receive motion control apparatus and carry out moving interpolation along the direction of motion that sets, and the different measured positions of measured object are placed under the image capturing equipment.
S4: after XY motion workbench and high-precision servo rotary table moved to the measured position point of setting as reference point take mechanical zero, motion control apparatus sent trigger pip.
S5: the trigger pip triggering high-speed image that motion control apparatus sends obtains equipment and obtains the measured position dot image, by host computer image is processed, obtain required measurement size, kinematic system is still among next measured position point motion when obtaining image, then can carry out the measurement of the next position point, carry out so continuously until all location point measurement end.
