What are the factors that affect the measurement speed of the image measuring instrument?1

Most friends who know image measuring instruments know that image measuring instruments can quickly measure three-dimensional geometric dimensions and form product tolerances without touching the product surface, so the efficiency is very high. So what are the factors that affect the measurement speed of image measuring instruments? 1. The choice of the measuring method of the image measuring instrument is the decisive factor. The speed of non-contact measurement is several times that of contact measurement, and the application of automatic measurement program not only eliminates human error, but also ensures higher efficiency of batch measurement. 2. The servo system of the image measuring instrument controls the mechanical movement performance of the platform. When editing the program, the joystick needs to control the platform with very small steps, because the measurement accuracy of the image measuring instrument reaches the micron level, so the control accuracy of the joystick is also a corresponding issue that needs to be considered. The acceleration expression of the start and stop of the platform movement, under the premise of ensuring the measurement accuracy, the faster the movement speed and acceleration, the better the positioning accuracy and performance of the movement. 3. The measurement software of the image measuring instrument usually completes a large amount of data analysis and calculation in the measurement background, and synchronously outputs the measurement results. If the speed of image analysis and computer processing is low, it will affect the operating speed of the image measuring instrument. 4. The more important point is that for fully automatic image measuring instruments, if the configured light source is insufficient, the imaging of some weak edges and chamfers is not clear enough, and the image analysis and software blur control are not good enough. If the wrong boundary is captured, the surveyor using the image measuring instrument must be able to see the boundary in real time. Then stop and modify this step manually, which will not only waste a lot of time, but also seriously affect the measurement accuracy and greatly reduce the measurement efficiency. 5. Product manufacturing usually contains three-dimensional parts. If the image measuring instrument can only measure two-dimensional dimensions, and the contact method is used in the height direction, the inspection efficiency will be greatly reduced. Therefore, choosing an image measuring instrument that can measure three-dimensional dimensions without contact is essential to increase the measurement speed.
