Measuring tube 1, its lower port be provided with lighting device and in use this lower port be suitable for entirety and enterThe water surface 2, upper port place establishes a camera head, and this camera head is suitable for taking the water in described measuring tube 1Face is as 2-1;
Video acquisition module, is connected and is suitable for collection image to be transformed to digital picture with described camera head;
With the image processing module that described video acquisition module is connected, this image processing module storesOne sample data, described the first sample data is suitable for recording the gray value of various water quality;
Be connected with described image processing module for receiving remote control signal and export water quality situationWireless communication module;
Be located at the peripheral float for this measuring tube is vertically bubbled through the water column of described measuring tube, this is floatingSon is located on described measuring tube for dish type and fixed cover, and described screw comprises that Central Symmetry is distributed in instituteState three on float; Described wireless communication module is connected with for according to described remote control signal controlMake the duty of each screw, to control in real time the spiral shell of the position of described measuring tube on the described water surfaceRevolve oar controller;
Described image processing module is suitable for described digital picture to carry out gray scale processing, to obtain described waterFace is as the gray value of 2-1, and this gray value and the first sample data are compared and drawn water quality situation.
Water quality detection principle is to utilize the corresponding gray value sample of different quality and water surface image to be detectedGray value compare, image processing module stores each gray value sample of different quality,The first sample data.
Adopt MATLAB built-in function to carry out corresponding gray value processing to described water surface image 2-1, step asUnder:
I=imread (' image.jpg '); % opens pending picture (8 gray scales)
Imshow (I); % shows this picture
C=mean2 (I); The mean value of % computed image picture element matrix
Just can calculate the gray value of described water surface image 2-1 by mean2 function.
Table 1 is the average gray value of various water quality, i.e. the first sample data:
According to general general knowledge, the water quality quality of these water samples can be arranged like this: pure water > green tea water> swimming-pool water > river > be mixed with the water of mud > by the water of dye discoloration > industrial wastewater ≈ prepared Chinese ink water, work as waterSampler body gradation of image value (brightness value) more hour, can think that its water quality is poorer, and vice versa. CauseAnd in the time of water quality detection, can be by the corresponding water quality conclusion of calculating of water body overall gray level,Can also pass through the more senior processing means such as sample extraction, neutral net, pattern-recognition, accomplish inspectionThe more water quality index of refinement such as survey turbidity.
For example, if the gray scale of the water surface image 2-1 detecting is 85, draw this water quality and riverWater quality is suitable.
