Analysis of Error Sources in Video Measuring Machines — Why Measurement Data Changes Over Time
It is very common for video measuring machines to show variations in measurement results after being used in industrial environments for a period of time. In most cases, this is not caused by equipment failure, but by the gradual accumulation of multiple system-related factors during long-term operation.

Principle of Vision Measuring Machine (VMM): How Pixels Are Converted into Real Dimensions
In a Vision Measuring Machine (VMM), the camera does not capture real-world dimensions. Instead, it acquires a two-dimensional image made up of pixels. Each pixel only represents light intensity or color information and does not contain any physical unit such as millimeters or microns.
