Schematic of the Principle

Our line-scan camera is equipped with a line scan image sensor capable of achieving high resolution, a large field of view, and high-speed detection of ultra-high-level pixels. This technology is particularly effective in the inspection of continuous materials, such as metals, plastic, paper, and fibers.

For example, a 12 K line-scan camera, with a line pixel count of 12,288 pixels, can achieve a maximum acquisition speed of 8 kHz. This allows the camera to produce an image measuring 12,288 x 8,000 pixels in just one second, compared to a 5M camera that offers a resolution of 2592 x 1944 pixels.

System Features

1. Enhanced field of view for image acquisition

Our black-and-white line-scan camera employs advanced scanning imaging technology and can simultaneously meet the requirements of high resolution and large field of view in image acquisition. This system achieves spatial resolution that is four times higher at a lower cost compared to similar color cameras.

Larger Field of View for Image Acqusition

2. Consistent lighting for surface detection

Our system employs a linear scanning method to inspect products, enabling the adaptive detection of various curved surfaces. This approach offers a distinct advantage over conventional area-array scan cameras, which require additional image correction algorithms. Such algorithms not only escalate computational cost but also tend to introduce greater deviations in the output.

surface detection

The system can perform defect detection for cylindrical, basiconical, and regular surfaces, such those of Bluetooth speakers, lateral surfaces of beverage cups, mobile phone, and scratches on screens.

3. Advanced defect detection by multi-spectral technology

Our black-and-white line-scan cameras utilize multi-spectral synthesis technology to obtain high-fidelity color images. This technology enhances detection of color-related defects. The cameras can also operate at special wavelengths that detect defects invisible to the human eye, such as fingerprints, oil stains, and water stains.

Notes:

• Dual camera detection: Line-scan camera 1 and line-scan camera 2 inspect the upper and lower surfaces of the titanium coil, respectively.
• Stabilization and measurement: An encoder is utilized to stabilize camera operation during imaging; a laser rangefinder accurately measures the thickness of the titanium coil.
• Data processing and monitoring: All captured data are processed at an intelligent analysis terminal, with real-time monitoring enabled by the network.
