The invention discloses a green vision rate collection system and method for ecological environment monitoring, and the system comprises a street view collection vehicle which is a carrier for the investigation and collection of the green vision rate of a motor vehicle lane, and comprises a vehicle body and a mechanical fixing part which is used for fixing a collection device to a vehicle roof; the GNSS equipment is used for positioning the acquisition equipment and acquiring a system track; the speedometer is used for recording the walking mileage of the acquisition equipment, is used for controlling the exposure distance of the camera, and is mounted on an automobile hub; the controller is used for recording automobile distance data, receiving GNSS time serial port synchronous PPS pulses, calculating the actual moving distance in real time and sending camera trigger exposure TTL signals, the camera is fixed to the position 1.6-1.8 m away from the ground by selecting a 20 mm focal length lens and a 35 mm full-frame camera and designing a height-adjustable sliding rod mechanical structure, a clear imaging view field of the camera in the horizontal direction of 84 degrees and the vertical direction of 62 degrees is guaranteed, and the distance between the camera and the ground is adjusted. And the effect of simulating human vision is achieved. The green vision rate acquisition system for ecological environment monitoring provided by the invention has the effect of simulating human eyes to receive green information.
