Embodiment 1

[0017] To monitor a scenic spot in Dianchi Lake, use a color CCD camera and an image acquisition card to obtain and store real-time patterns of the lake every hour from 7:00 a.m. to 7:00 p.m., and then use a computer image processing program to convert them into grayscale images , then calculate its one-dimensional and zero-dimensional Betty numbers, and then calculate the average value to obtain the monthly change curve of the average value, and observe the fluctuation of each average value. If it is within the controllable range, that is, the change trend is not large. , it indicates that large-scale reproduction will not occur in the area, and if the change is rapid, it indicates that the area will face the rapid reproduction of microorganisms, and measures should be taken in advance. After one month of recording and monitoring, the data obtained are as follows: image 3 shown, by image 3 It can be seen that the growth is normal and no explosive reproduction occurs.

Embodiment 2

[0019] To monitor a forest area, use a color CCD camera and an image acquisition card to obtain real-time patterns every 1 hour from 7:00 a.m. to 7:00 p.m. and store them, and then use a computer image processing program to convert them into grayscale images , and then calculate its one-dimensional and zero-dimensional Betty numbers, and then calculate their average. After one month of recording and monitoring, the data obtained are as follows: Figure 4 shown, by Figure 4 It can be seen that the abnormal growth of pests occurs explosively.

Abstract

The invention discloses a method for monitoring and preventing explosive breeding of various algae and pests. In the method, the breeding state of organisms such as the algae and the like is judged by acquiring image features. The method comprises the following steps of: (1) acquiring a color image by utilizing a camera or image acquisition equipment, inputting the image into a computer, converting a color image signal into a grey image first and then calculating a zero-directional Betty number and a one-dimensional Betty number by using a chomp method; and (2) judging whether the explosive breeding happens in the near future according to the growth of the Betty numbers. The method is simple and easy to implement, can monitor and prevent the explosive breeding of the organisms sensitively, rapidly, reliably and instantly, and provides a reliable method for monitoring and preventing the abnormal breeding of the organisms so as to protect ecological preservation areas, wetlands, national forest parks, lakes, world natural heritages and the like. The method is mainly used for organism growth monitoring and abnormality preventing in lake swamps and the ecological preservation areas.

Description

technical field [0001] The invention relates to the technical field of biological reproduction monitoring, in particular to a method for monitoring and preventing the explosive reproduction of various algae and pests. Background technique [0002] The mass reproduction of organisms will lead to various hazards. For example, if the pests in the forest area explode, the ecology of the entire forest area will be destroyed or even the forest area will be destroyed, and the algae will cause a large number of other plants in the water to die. The corpse encourages bacteria to multiply, depriving the water of oxygen and killing the fish. The experiment was designed with the method of controlled variables, and different substances were added to the same amount of river water. Finally, it was concluded that nitrogen, potassium and phosphorus were the main factors. The algae in the water body can not only cause the water body to stink and turn green and black, but also produce algal ...
