Problems solved by technology

[0002] With the continuous improvement of people's living standards, people's awareness of environmental protection is also constantly strengthened. The existing river pollution factors are mainly the discharge of domestic sewage and industrial wastewater. At the same time, the discarding of domestic garbage will directly lead to the pollution of river water. , when the domestic garbage in the existing river has accumulated to a certain amount, it will be cleaned up. However, the river has already been polluted at this time. Therefore, timely detection of river floating objects and timely treatment can reduce For the further pollution of rivers and rivers by domestic garbage, most of the existing detections use artificial observation to observe the number of floating objects on the water surface of the river, but the observation is not only labor-intensive, but also the detection accuracy is not high, and there are human subjective judgments. Therefore, people urgently need a water surface floating debris pollution evaluation system and its method based on big data to solve the above problems

Abstract

The invention belongs to the technical field of big data and water environment and discloses a big data-based water surface floating object pollution evaluation system and method. The water surface floating object pollution evaluation system and method based on big data. The method is scientific and reasonable, safe and convenient use. According to the system and method, river channel water surface images are collected through a camera; a riverway water body model is established by utilizing a model establishing unit; an intelligent identification unit is used for scanning and calculating themodel; the position of a river channel water surface floating object is judged by utilizing a formula; the difference value of two adjacent coordinate points is calculated, so that the measurement precision of the floating object can be effectively improved; and a reference surface unit is used, and therefore, the length of the floating object can be accurately measured, the judgment of the numberof floating objects on a water surface can be facilitated; and the timely knowing of the pollution degree of the floating objects on the water surface of a river channel can be facilitated, the floating objects of the river channel water body about to be severely polluted can be timely salvaged, the further pollution of the river channel water body can be effectively prevented, and the improvement of water environment pollution can be facilitated.
