AI Technical Summary
Existing two-dimensional imaging raindrop spectrometers cannot accurately detect the horizontal velocity and orientation of precipitation particles. They suffer from issues such as non-horizontal installation and azimuth errors, inability to dynamically adjust thresholds, inability to detect the phase state of precipitation particles, and lack of efficient power supply and maintenance in the field.
A high-precision precipitation particle detection system is adopted, including an orthogonal high-speed line scan camera unit and a background light source. It combines a gyroscope and an electronic compass for real-time correction, uses multi-angle imaging for three-dimensional reconstruction, dynamically adjusts the light source threshold, installs a heating defrosting unit and environmental detection, and sets multiple working modes to optimize power consumption.
It achieves high-precision detection of precipitation particles, including accurate measurement of shape, size, flatness, orientation and type, improving the efficiency and lifespan of the equipment in the field and reducing power consumption.
