With the increasing demands of modern production and scientific research on image acquisition systems, high-speed line scan cameras , as front-end devices for digital image acquisition and transmission, largely determine the performance of the entire system through their scanning speed and quality, making them the preferred choice for cost-effective inspection solutions.
Using a line scan camera, images of continuously moving items under inspection can be captured in real time. The captured images are then transmitted to a computer for image processing via an image acquisition card. This allows for defect detection of products moving on automated production lines or in continuous motion. It also enables the localization, detection, and defect identification of moving images, with defect location markers provided for defect identification. This technology is suitable for teaching and research experiments involving continuous image acquisition, image processing, pattern recognition, and defect detection of products in continuous printing, steel strip processing, and fabric production.
The design of a high-speed line scan camera system mainly includes two parts: the camera's hardware structure and the related software for camera operation. Structurally, a line scan camera, as an image acquisition and visual information acquisition device, primarily functions to convert optical image signals into digital image signals. Generally, it consists of an optical imaging section, a photoelectric conversion section (converting analog light signals into analog electrical signals), and an A/D converter. The photoelectric conversion section is typically implemented using a solid-state image sensor.
Image acquisition based on horizontal scan line technology involves a large amount of data. To upload these large amounts of images to the computer in real time and quickly, a certain transmission rate is required for the data transmission interface. Among the current computer interfaces, the LVDS interface meets the requirements for high-speed communication and is easy to use in design.
The camera's operating modes are comprehensively considered to adapt to different working environment requirements. These modes are categorized into four types: active real-time acquisition, active non-real-time acquisition, passive real-time acquisition, and passive non-real-time acquisition.
