Machine vision technology essentially replaces the human eye with a camera and uses image processing software to mimic the brain's function in identifying or verifying products. The system typically includes components such as a light source, lens, camera, image acquisition card, image processing software, and necessary I/O interfaces. Machine vision offers high efficiency, consistency, and accuracy, making it irreplaceable in many industrial applications where precision is crucial. As a result, it is widely used in automation engineering for tasks like product quality inspection and assembly verification.
The inspection task requires measuring the distance between four key parts of the product—A, B, C, and D—as shown in the diagram below:
The testing equipment used includes an IEEE1394 camera, a 1.4/16mm lens, a strip light, and a Nokia BL-5C 1020mAh sample battery. The setup involves precise positioning: the distance between the camera lens and the stage is approximately 19 cm, while the left strip light is placed about 7 cm high. The angle between the beam and the vertical axis is around 60°, and the vertical line of the strip aligns with the sample battery.
At a distance of 4.5 cm, the front strip light is positioned directly on the stage, at a 90° angle relative to the left strip, and approximately 4 cm away from the sample cell. Below are additional images showing the setup and results:
In terms of detection effect, the system performs well under controlled conditions. However, electronic production test equipment often integrates opto-mechatronics, requiring a seamless combination of machine vision, motion control, and data acquisition. Many domestic manufacturers lack experience in integrating these technologies effectively, leading to increased reliance on external technical support during R&D and system integration. Additionally, current suppliers of machine vision, motion control, and data acquisition systems often operate independently, making it challenging to develop comprehensive solutions for specific applications.
To address this issue, Euresys has partnered with ADLINK, a leading manufacturer of high-end industrial computers using CompactPCI and PXI technologies. This collaboration enables the delivery of fully integrated industry solutions that combine advanced machine vision, motion control, and data acquisition technologies, helping equipment manufacturers and system integrators achieve more reliable and efficient performance.
