What is the impact of machine vision measurement accuracy?

In recent years, the application of machine vision system has been very extensive, and the high precision, high detection efficiency and low production cost of machine vision system have been favored by enterprises. No matter how good things will also have problems, machine vision system in the use of the process, due to the influence of various factors, the measurement accuracy will be reduced, to the enterprise inconvenience.

There are many factors that affect the measurement accuracy of machine vision inspection equipment, including the brightness, uniformity and directivity of the light source will directly affect the quality and clarity of the image, affecting the measurement accuracy.

Lens resolution, distortion, lens quality, and correction all affect image sharpness and distortion, which in turn affects measurement accuracy. Parameters such as the camera's resolution, frame rate, dynamic range, noise level, and color accuracy affect the quality and stability of the image, which in turn affects the measurement accuracy. Ambient light, temperature, humidity and other factors will affect the quality and stability of the image, and directly affect the accuracy of the measurement. Different image processing algorithms will affect the measurement results, and selecting the appropriate algorithm can improve the measurement accuracy.

Correct camera calibration and system calibration are critical to measurement accuracy, and incorrect calibration and calibration can lead to measurement errors. The reflection, color, texture and other characteristics of the object surface will affect the quality and sharpness of the image, and then affect the accuracy of the measurement.

The stability and accuracy of the mechanical structure of the machine vision system will affect the measurement accuracy, and mechanical vibration or deformation will affect the accuracy of the measurement results. The resolution and magnification of the camera will affect the capture and display of details in the image, and directly affect the accuracy of the measurement.

The accuracy of data acquisition, processing and analysis is also an important factor affecting the measurement accuracy, and the error of data processing will directly affect the accuracy of the measurement results.

By optimizing the above factors, the measurement accuracy of machine vision inspection equipment is improved to ensure that it can be accurately and reliably measured and tested in various application scenarios.
