Description

Rape transplants field operation quality on-line monitoring system and its monitoring method
Technical field
The present invention relates to a kind of rapes to transplant field operation quality on-line monitoring system, is adopted based on image The rape transplanting operation quality real-time monitoring system and method for collection processing.Especially suitable for the rape transplanting under the handling situations of crop field The real time on-line monitoring of operation quality belongs to farmland management apparatus field.
Background technique
China's winter rape planting site is mainly rice cultivation before winter rape plantation mainly in middle and lower reach of Yangtze River Plain, Rice-rape or rice-rice-rape rotation system are generallyd use, since harvest implantation time is nervous, using live streaming Mode will will lead to growth of rape period deficiency, therefore middle and lower reach of Yangtze River Plain mostly uses the mode of transplanting to carry out, rape transplanting Mode can shorten the turnaround time, ensure that reasonable crop rotation, to realizing that stable yields and high yield have great significance.Current Rape-transplanting machine in, lack operation quality monitoring, need manually uninterruptedly to be observed, influence mentioning for equipment operating efficiency Height, increases manual labor's intensity, and operation quality cannot be guaranteed.Therefore rape transplanting operation quality real time monitoring has important Meaning.
Has the quality-monitoring patent disclosure for being predominantly directed to rice transplanting at present, since paddy-field-working error is small, not Consider influence of the image calibration to calculated result.But during field transplanting rape, rape planting density is big, and nonirrigated farmland is smooth It is poor to spend, and height injustice problem in field is affected to calculating in quality monitoring process, cannot be according to equipment during actual job Working condition is recorded and is counted in real time, and being uneven for field influences spacing in the rows and plant number during transplanting.By upper The influence for stating factor causes spacing in the rows calculating error larger using the image processing method of no calibration, influences planting quality statistics essence Degree.
The quality monitoring of rape transplanting at this stage is not directed to big substantially to judge rice shoot whether there is or not based on before planting seedling taking The operation quality when operation of field monitors problem on-line.Due to practical farm work situation difference, system is monitored after the cultivation of other crops System not can be used directly transplants in rape.
Summary of the invention
In view of the deficienciess of the prior art, it is an object of the present invention to provide a kind of oil highly reliable, calibration accuracy is high Dish transplants field operation quality on-line monitoring system.
To achieve the goals above, the present invention is to realize by the following technical solutions: rape transplants farm work matter On-line monitoring system is measured, including transplantation device and the feeler mechanism for being installed on transplantation device rear, it is characterised in that: further include moving Monitoring system is planted, the transplanting monitoring system includes the range sensor for being connected to transplantation device rear baffle side, is located at transplanting Adjustable support on the crossbeam of device tail portion and the outer case being fixedly installed on the adjustable support;It is set in the outer case There are camera, industrial personal computer and calibration sensor;The range sensor for monitor in feeler mechanism connecting rod to baffle side it Between horizontal distance;The calibration sensor is for measuring height of the industrial camera apart from ground.
When transplantation device preparation work, feeler mechanism controls its whereabouts, and connecting rod reduces to distance between rear baffle side, When distance is less than closure nodal value, distance sensor signal is transmitted to industrial personal computer, and industrial personal computer controls camera and calibration sensor The closure of circuit;When distance is greater than disconnected node value, distance sensor signal is transmitted to industrial personal computer, industrial personal computer control camera, The power supply for calibrating sensor disconnects;Work as camera, when calibration sensor is in running order, the image of shooting is carried out in industrial personal computer Processing, constantly calculates and feeds back to operator;When calculated value is less than setting index, alarm signal can be issued in real time and reminds operation Person.
The invention further relates to a kind of monitoring methods of rape transplanting field operation quality on-line monitoring system, it is characterised in that Including the following steps:
The foundation of the first step, calibration data base
1.1) select range for L1, the apparent ruler of scale, which is used as, demarcates object, and ruler is fixed on ground;
1.2) camera is fixed on the adjustable bracket of height, by the adjusting of support height, drives calibration sensing The height change of device;
1.3) since apart from ground 50cm height, stop to 250cm, every 1cm shoots a photo, shoots 200 altogether Photo;
1.4) picture is printed, and measures the length L that the ruler of scale is fixed on pictureX’
1.5) repeatedly shooting, takes the average value of measurement as LX
1.6) using apart from ground level as abscissa,For ordinate, scatter plot is established, the functional image being fitted;
Image processing step after second step, rape transplanting
2.1) laplacian spectral radius is carried out to the image after rape transplanting, improves the contrast of image;
2.2) binary segmentation is carried out to image based on Otsu method;
2.3) image is corroded using M radius different circular structural elements, utilizes the different pros of N number of side length The structural element of shape expands image M1, and selecting the least combination in abnormal communication domain is optimal expansion structure element;
2.4) bianry image progress is first corroded using optimal corrosion expansion structure element and is expanded afterwards, obtain image A;
2.5) according to fractional spins, the profile and area of image A is obtained, mass center is calculated;
2.6) successively photo is registrated, calculates the Euclidean distance X between adjacent connected domain mass center;
Third step, industrial personal computer calculate aligning step
3.1) functional image obtained according to calibration sensing data, industrial personal computer obtain actual height pair by interpolation calculation The error coefficient K answered;
3.2) comprehensive distance Y, Y=K × X is calculated in industrial personal computer, and as Y>=300mm, as leakage is carried, as Y<300mm When, as normally transplanting state, record Plug seedling number M, leakage carry number M0
3.3) spacing in the rows Y is exported, load rate P is leaked,
3.4) as P >=8%, start to trigger alarm condition, operator's transplanter is reminded to break down.
Beneficial effects of the present invention: the present invention solves rape transplanting operation quality monitoring problem, can be made according to equipment Industry state realizes monitoring results automation;Based on image processing techniques, on-line monitoring, real-time feedback information are realized;Utilize height Sensor real time calibration is spent, spacing in the rows is reduced and calculates error.In rape transplanting experiment, show to calculate data ratio by calibrating installation Without the data of calibration, error reduces 5%, while counting without human assistance, reduces human cost and improves effect Rate and accuracy.The present invention can judge equipment job state and realize rape planting hole number under the handling situations of crop field, while energy Automatically the data of the planting qualities information such as acquisition seeding row spacing, leakage cultivation, lodging are, it can be achieved that rape transplants the view that height is different in the process Angle calibration.Sampling visual angle real time correction, solving the not gentle equipment in ground highland in rape transplanting operation process, spring etc. is led up and down The spacing in the rows of cause calculates the problems such as inaccuracy.
