Problems solved by technology

[0006] However, in the above-mentioned non-stop measurement system, the image information captured by the flashlight while the measurement platform is moved relative to the imaging means is input at the measurement position, so there is a conventional method of stopping and adjusting illumination for each measurement position that cannot be applied as it is. Problems with the teaching method in standard mode

Embodiment approach 1-1

[0041] Image 6 It is a diagram showing an example of a generated partial program.

[0042] This part of the program includes three subroutine blocks (Sub QVBlock_1, Sub QVBlock_2, SubQVBlock_3). In the first sub-block (Sub QVBlock_1), setting commands such as lens magnification and illumination are described in the first two lines, followed by movement route commands indicating movement of each measuring element, strobe lighting, and image acquisition. The second and third sub-blocks (Sub QVBlock_2, SubQVBlock_3) are measurement blocks.

[0043] In order to create such a partial program, the program creation unit 36 ​​executes the following steps.

[0044] (1) Among the continuous moving route commands, the moving route command of one measuring element and the corresponding image reading command and image processing command (edge ​​detection, etc.) are produced in parallel by two subroutine blocks.

[0045] (2) The command of (1) above is generated for all route parts. Im...

Embodiment approach 1-2

[0056] In Embodiment 1-1, in order to adapt the partial program itself to the structure of non-stop measurement, in Embodiment 1-2, the partial program itself is substantially the same as the standard mode, and the processing in the partial program execution unit 38 is different from conventional ones. .

[0057] Figure 9 It is a figure which shows the partial program of this Embodiment 2.

[0058] In the partial program, an instruction to switch to the non-stop measurement mode is described at the front end, and an instruction to switch to the standard mode is described at the end. Part of the program is the same as Embodiment 1, including three subroutine blocks (Sub QVBlock_1, Sub QVBlock_2, Sub QVBlock_3), but in the first sub-block (SubQVBlock_1), there are instructions for setting measurement conditions such as lens magnification and illumination, and in the second And the third sub-block (Sub QVBlock_2, Sub QVBlock_3) describes the movement of the measurement positio...

Abstract

The invention provides an image measuring system and a method for producing and executing non-stop image measuring program. It comprises following steps: moving camera corresponding to measuring table according to table motion indication input; spotting flash lamp illumination with regular cycle, and moderating the impulse width of flash lamp illumination according to illumination moderation indication input to adjust illumination quantity for workpiece; loading information about camera position in relative to measuring table and information about flash lamp illumination impulse according to regular indication input, passing workpiece from position demonstrated by input position information, and lighting flash lamp at said position, inputting instant image information of workpiece and generating part program for image measurement.

Description

[0001] This application is based on and claims priority from Japanese Patent Application No. 2005-164602 filed on June 3, 2005, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to an image measurement system having a non-stop measurement mode and a method for making and executing a non-stop image measurement program. Instantaneous image information is obtained without stopping to perform image measurement. Background technique [0003] In the past, such as Figure 12 As shown in the figure, the CNC image measuring machine moves the measuring table relative to the imaging device such as a CCD camera, stops it at the measuring position, adjusts the amount of illumination light at the same time to obtain image information of the object to be measured, and performs measurement tool setting and edge measurement on the obtained image information. Detection and other image processing, thereby performing a meas...
