The manual image measuring instrument comprises a taking device, a data acquisition device, and two-dimensional measurement software. The zoom objective plus high-resolution color camera constitutes an image-taking device, and the raster ruler and data processor constitute a data acquisition device. The image and data are measured by 2D measurement software to achieve point line arc and distance measurement. High Precision Fast Detection Instrument Instrument application field: The image-measuring instrument is built based on CCD digital images, relying on computer screen measurement technology and the powerful software capability of spatial geometry operation. After the computer is installed with extraordinary control and graphic measurement software, it becomes a measurement brain with software soul and is the main body of the entire equipment. It can quickly read the displacement value of the optical ruler and obtain the desired re…
