Put, when taking pictures, when having certain angle preferably between sunlight and ground, it may be necessary to light compensating lamp is used, so that
The size of soil particle shows as the size of dash area in the picture;
Step 3: image processing apparatus is handled the image received and calculates garrulous soil rate;
Step 4: image processing apparatus stores and forwards garrulous soil rate.
In the step 3, the processing procedure of image of the image processing apparatus to receiving includes:
Step S1, image processing apparatus carries out discoloration processing to image, obtains step processing image, as shown in Figure 2;
Step S2, image processing apparatus adjusts the brightness and contrast of step processing image, obtains two steps processing image, such as
Shown in Fig. 3;
Step S3, image processing apparatus carries out color screening to two steps processing image, retains black in two steps processing image
Color part, three step process image is obtained, as shown in figure 4, black picture element is the shade of soil particle in four steps processing image;
Step S4, three step process image is converted into bitmap by image processing apparatus, obtains four steps processing image, and calculate four
The quantity m of black picture element in step processing image;
Step S5, four steps are handled several connected black picture elements in image and are divided into an area by image processing apparatus
Block, symbiosis symbolize the size of soil particle into multiple blocks, the size of block.The method of block division is, to any one picture
Element is judged, if the pixel is white, does not process, then its adjacent pixel is judged, if the pixel is
Black, then pixel that is adjacent and having common edge of aliging is judged that such pixel shares four, if this four pixels
In have black picture element, then the pixel and adjacent black picture element are merged into a block of cells, and to adjacent black picture element after
It is continuous to carry out foregoing judgement, until the edge of a block does not have adjacent black picture element, then the division of the block is completed, in reality
In the application process of border, for a photo, judgement is proceeded by from the pixel of the first row first row;
Step S6, image processing apparatus calculates the pixel quantity in each block, if pixel quantity is less than k, Ze Jianggai areas
Pixel in block is adjusted to white, if pixel quantity is more than or equal to k, the block is constant, and all block processes are finished
Afterwards, obtain five steps processing image, as shown in figure 5, and calculate five steps processing image in black picture element quantity n.
In the step 3, the method that image processing apparatus calculates garrulous soil rate is garrulous soil rate x=(m-n)/m, cloudy by calculating
The larger soil particle of shadow area accounts for the ratio of all soil particles, to obtain the garrulous soil rate of rotary cultivator.
Because rotary cultivator it is cultivated go out the garrulous soil rates of soil levels be essentially identical, therefore by calculating top layer hack
In approximate can draw the overall garrulous soil rate of rotary cultivator.In addition, garrulous soil rate will not generally be sent out because of rotary cultivator in the course of the work
Raw very big change, therefore the detection to garrulous soil rate is carried out without continuous, after one-time detection has been carried out, waits rotary cultivator
Second of detection is carried out again after travelling certain distance.
The method of image processing apparatus forwarding garrulous soil rate is is wirelessly transferred in the step 4, by the way that garrulous soil rate is passed in real time
Operating personnel are defeated by, the working condition of rotary cultivator can be monitored in real time, be easy to be adjusted rotary cultivator.
The utility model obtains soils particles size percent content information, and then obtain by being taken pictures to soil and photo being handled
To the garrulous soil rate of rotary cultivator.Because it is that soils particles size percent content is characterized by soil particle shade size, therefore photo needs
The shade of soil particle can be photographed, so sunlight oblique illumination is needed when taking pictures on soil, when necessary
Light compensating lamp can be increased on auxiliary head.The height of image acquisition device 7 can be adjusted flexibly, so as to the soil covered to photo
Area is adjusted, and disclosure satisfy that the use demand in different soils, when the soil erosion that photo is covered is bigger, computational efficiency
High still to sacrifice certain precision, when the soil erosion that photo is covered is smaller, precision is higher.
