Ice flood observation system based on technology of computer vision

Abstract

The invention discloses an ice flood observation system based on the technology of computer vision. A system which consists of an observation device, data processing equipment and terminal equipment is designed, wherein the observation device and the data processing equipment are in wireless signal connection. Moreover, a data collection and processing method based on the above system is also designed, and the method comprises the steps: automatically collecting image data through a camera mechanism, and transmitting the image data to the data processing equipment through a wireless signal; carrying out the image space conversion of the image collected by the camera mechanism through the data processing equipment, thereby achieving the quantitative analysis of ice flood distribution image data of a river. The beneficial effects of the invention are that the structure is simple; the design is reasonable; the system reads the ice flood data of engineering observation points in a region from one display according to the collection time; the system is high in data reading precision, is high in timeliness, is convenient and quick, can save a large amount of observers, alleviates the labor intensity, and eliminates the personal potential safety hazards.

Description

technical field [0001] The invention relates to a water conservancy monitoring device, in particular to an ice flood observation system based on computer vision technology. Background technique [0002] In the areas along the Yellow River in northern China, it is very cold in winter, especially the people on both sides of the lower reaches of the Yellow River suffer from the flood caused by the blockage of ice. It is the unremitting pursuit of the people to control the Yellow River over the years to dredge the river and prevent ice floods. Therefore, it is necessary to conduct winter ice observation. It is one of the important means to grasp the first-hand information on changes in the ice period of the river and to prevent and control floods. Ice observations are generally carried out in three periods: the ice period, the freezing development period, and the river opening period. The personnel pay close attention to the changes of ice snow, and the staff of each observation...

[0002] In the areas along the Yellow River in northern China, it is very cold in winter, especially the people on both sides of the lower reaches of the Yellow River suffer from the flood caused by the blockage of ice. It is the unremitting pursuit of the people to control the Yellow River over the years to dredge the river and prevent ice floods. Therefore, it is necessary to conduct winter ice observation. It is one of the important means to grasp the first-hand information on changes in the ice period of the river and to prevent and control floods. Ice observations are generally carried out in three periods: the ice period, the freezing development period, and the river opening period. The personnel pay close attention to the changes of ice snow, and the staff of each observation point pay close attention to the ice ice changes of the river channel around the clock, especially the dangerous river sections such as narrow channels and bends. Observations and records of shore ice conditions and other aspects are carried out, and these tasks rely on observers to record and calculate observations based on experience and visual estimation. The sorting and reporting of the observed data on the day must be done by hand. It does not meet the requirements of modern high-speed development of electronic information technology, and this visual estimation method has large errors in observation data, takes up a lot of personnel, is inconvenient to observe in windy and snowy days, and has personnel unsafe factors, etc.
