| description | According to the rainfall detection device based on computer vision, the first differential circuit calculates a speed difference signal, the speed difference signal calculates a rate signal in unit time through the integrating circuit, when the rate signal is high or low, the rate signal goes through the integrating circuit, the integrating time is adjusted, the rate signal goes through the camera main controller, and the shooting frequency of the camera is adjusted; a speed difference signal enters a difference comparison circuit, a flow signal is calculated, enters a second difference circuit and is compared with a measuring ruler strip variation signal difference, and a low or high level corresponding to a small or large deviation value is output and is output to a compensation circuit; a flow signal is subjected to error signal adjustment and evaporation capacity signal superposition compensation, is output to a field processor when a rate signal is high, is transmitted to a far-end computer by the field |
