VCX-400 video dynamic brightness measurement system is an intelligent measurement device designed for dynamic brightness test needs. It integrates dual-frequency GPS + Beidou positioning module and can be used for dynamic testing of outdoor dynamic landscape lighting, dynamic billboard brightness, road and tunnel pavement brightness, etc. Ultra-high-speed dynamic measurement, up to 30 frames/second continuous acquisition, supports real-time road brightness measurement at vehicle speeds ≤60km/h.
The high dynamic range imaging technology can handle a wide range of brightness changes, avoid overexposure or underexposure, and can measure the brightness of multiple points or areas at the same time to improve measurement efficiency. In lighting design and evaluation, the brightness distribution and uniformity of street lighting can be measured. The measurement method based on high dynamic range imaging technology can be used to detect extreme brightness distribution in night road lighting scenes. It can capture and analyze brightness changes in video images in real time and is suitable for monitoring dynamic scenes.
