I. Understanding the QCT 1128 Standard: The "Quality Benchmark" for Vehicle Cameras
The QCT 1128 standard is a national industry standard specifically formulated for the image performance and reliability of automotive cameras (such as forward-view, surround-view, rear-view, and electronic mirror cameras). It stipulates a series of key performance indicators that vehicle cameras must meet before installation. The standard aims to ensure that these cameras can provide clear, accurate, and stable images under various complex road and lighting conditions, serving as a reliable data source for ADAS (e.g., Lane Departure Warning, Automatic Emergency Braking) and driver's field-of-view extension systems.
II. Comprehensive Coverage of Test Items Required by the Standard
Our solution enables comprehensive image quality evaluation of vehicle cameras. The core test items cover:
Basic Performance: Frame Rate, Effective Pixels, Field of View (FOV)
Clarity & Detail Rendering: MTF (Modulation Transfer Function)
Photoelectric Performance: Signal-to-Noise Ratio (SNR), Dynamic Range, Maximum Luminance, Minimum Illumination, Automatic Gain Control
Color Performance: Color Reproduction Accuracy, White Balance Performance
Optical Defects: Lens Flare, Ghosting (Ghost Images), Geometric Distortion
Timing & Latency: Exposure Time, System Startup Time, Latency Testing
