Machine Vision and Industrial Robots

May. 15, 2021

Nowadays, the requirements for automation of production lines are getting higher and higher. Industrial robots possess the characteristics of high work efficiency and repeat positioning accuracy. It has become a trend to use industrial robots to replace humans. The task of the robot vision system is to capture the image through the vision sensor and transmit the image to the processing unit. Through digital processing, based on the pixel distribution and other elements to distinguish, then control the robot's actions.

Machine vision uses machines to replace human eyes for visual image processing and analysis. It involves optical imaging, sensor technology and other technology. It has the advantages of non-contact, good real-time, and a high degree of intelligence. It has been used in industries such as automobile manufacturing, medical image analysis and processing, logistics, and intelligent transportation.

The work efficiency and quality of industrial robots often depend on the accuracy of visual recognition of target objects and the accuracy of positioning. Therefore, industrial cameras are an indispensable structure in industrial robots. The industrial camera uses optical lenses and light source for image acquisition. The industrial camera should be installed as perpendicular to the transmission equipment as possible, so as to reduce the influence of distortion caused by image tilt.

Industrial cameras are an important visual sensor in the image acquisition process. The selection of industrial cameras directly affects the stability of the visual system. The role of optical lenses is mainly to modulate the light beam and focus the light of the imaging target object. The optical components commonly used in industrial cameras include infrared filters, beam splitting prisms, and biconvex lenses.

Aberration correction depends on the quality of optical lenses, which can be measured by the size of aberrations. Common aberrations include spherical aberration, coma, astigmatism, the curvature of field, distortion, and chromatic aberration. In machine vision systems, a fixed-focus lens is generally preferred, according to the state of the target under test. Factors such as image magnification, the field of view, aperture, focal length, and angle of view are also considered.
