Description

A kind of Semen Tritici aestivi spike number measurement apparatus and using method thereof
Technical field
The present invention relates to agricultural equipment technical field, particularly relate to a kind of Semen Tritici aestivi spike number measurement apparatus And using method, it is specifically related to a kind of can raising and measures the little of wheat head recovery efficiency and accuracy Wheat head number measurement apparatus and using method thereof.
Background technology
Semen Tritici aestivi spike number refers to the wheat head number in a certain wheat planting region, is that product process surveyed by Semen Tritici aestivi One of important parameter.Meanwhile, the preferably offer important evidence that Semen Tritici aestivi spike number is new variety of wheat, Therefore it is also one of the parameter that must measure of breeding expert.
At present, there is multiple method to be used for the measurement of wheat yield, mainly include that field is manually surveyed Amount, electric capacity survey product, climatic analysis prediction and year's harvest forecast etc..But, owing to field conditions is little Wheat growth is intensive, growing way is different and enormous amount, and the hand-held one meter of long ruler of breeding expert enters Field, the Semen Tritici aestivi quantity that in the different breeding plot independent rows of measuring and calculating, one meter of long scope is comprised, And then the wheat head sum in estimation community, this method wastes time and energy, and artificial at field conditions Number fringe, count results has much relations with the density of individual's subjectivity and selected counting region Semen Tritici aestivi, Different personnel are relatively big to the measurement result deviation in same plot, are difficult to obtain accurate data.Except this Outside, breeding plot enormous amount, region quantity to be measured is many and field conditions is complicated, manually Measurement efficiency is low.And electric capacity is surveyed product, climatic analysis prediction and year's harvest forecast method and be there is subjective shadow Ring big, cost height and the effect of the little scope accurate measure in local can not be accomplished.
Along with improving constantly of the breeding level of IT application, image recognition technology is utilized to carry out field wheat Fringe counting becomes a kind of trend.Have researcher the most both at home and abroad image procossing and video to be supervised During the application of control technology monitors with plant growth, such as: by photographic head based on can be by photoimaging side Method, extracts the color of the wheat head, textural characteristics, uses image analysis method to calculate wheat head skeleton number Amount and the quantity of wheat head skeleton useful cross, carry out wheat head quantity calculating;Or pass through digital camera Shooting is required measures wheat head photo, and captured wheat head photo is used image processing method, point Analyse based on color characteristic and wheat head dividing method based on image texture characteristic, and used the wheat head Skeleton angle point quantity carries out field wheat head counting.But, above-mentioned image recognition technology existing defects, Photographic head or digital camera shooting wheat head image is used to belong to visible images image pickup method, if Use the method that the method carries out land for growing field crops wheat head counting, owing to wheat head color and leaf color are close, And visible ray is easily affected by illumination factor at outdoor images acquisition process, it is difficult to ensure Image Acquisition Stability, it is difficult to fundamentally solve the field wheat head and accurately obtain a difficult problem.In addition, also Captured wheat head image need to be carried out a series of image characteristics extraction, such as color, texture And contour feature extracts, the most also needing the technical characteristic to extracting to refine, operating procedure is many, Also be unfavorable for wheat head quantity quick, accurately obtain.

S4, by the wheat head image in graphics processing unit analytical procedure S3, to obtain measurement frame Wheat head quantity in frame;Specifically, by the wheat head in graphical analysis subelement analytical procedure S3 Image also calculates wheat head quantity, to obtain the wheat head quantity in the range of gage frame 4.
Specifically, the main bag of wheat spike number metering is carried out according to acquired thermal infrared images Include following steps, the most as shown in Figure 2:
St1, acquisition field wheat head thermal infrared images;
St2, according to the wheat head in thermal infrared images and blade and the grey value difference of background, by ash Degree stretching conversion carries out image enhaucament, the most such as to the wheat head thermal infrared images obtained in step St1 Shown in Fig. 4;Specifically, gray scale tension values is set between 0 and 255, can be greatly enhanced the wheat head With the contrast between background (all pictures in addition to the wheat head, including blade and straw); If the gray scale of the wheat head and blade is distributed mainly between a to b, arrive if its gray scale is stretched to 0 Between 255, then in artwork gray value be the pixel of P stretched after gray value P0=255 ×(P-a)/(b-a);
After St3, threshold transformation, little area removes interference information, extracts wheat head image;After strengthening Step St2 in picture carry out threshold transformation, and the image after threshold transformation is carried out little area Remove interference information, obtain wheat head image, the most as shown in Figure 5;
The wheat head image obtained in St4, extraction step St3, and its each region is carried out respectively point Analysis, according to region concavity and convexity calmodulin binding domain CaM area, carries out wheat head quantity calculating;Specifically, knot Close concavity and convexity index (Convex) and the area (Area) in each region, carry out wheat head number calculating;Wherein, The area that definition is this region of the concavity and convexity index (Convex) in region is external with this region minimum The area ratio of rectangle, Convex value is the least, shows that this region shape is irregular, can be determined as 2 or the more wheat head are sticked together and are formed.
Concavity and convexity Convex according to each region and area Area, the calculating of Semen Tritici aestivi total spike number N Method is:
If Convex > 0.7 and Area≤1.5A, this region wheat head quantity is calculated as N1;
If Convex > 0.7 and Area > 1.5A, this region wheat head quantity is calculated as N2;
If Convex≤0.7 and Area≤2.5A, this region wheat head quantity is calculated as N3;
If Convex≤0.7 and 2.5A < Area≤3.5A, this region wheat head quantity is calculated as N4;
If Convex≤0.7 and Area > 3.5A, this region wheat head quantity is calculated as N5;
Semen Tritici aestivi total spike number N=N1+2 × N2+2 × N3+3 × N4+4 × N5;
In formula, A is the average area of the single wheat head.
Specifically, in step s 2, thermal infrared measuring unit is by data wire and image procossing list Unit connects, it is possible to by wireless connections or other signal connected mode.
Embodiment two
Further, support 3 is provided with the slide rail that vertical direction is arranged, gage frame 4 is passed through Slide block moves along slide rail, can carry out along the vertical direction of support 3 realizing gage frame 4 Altitude mixture control.Preferably, for reaching preferable shooting effect, gage frame 4 is located to be measured In region at wheat canopy.Wherein, vertical direction refers to be perpendicular to the direction on ground.Wherein, Slide block can be connected with motor, is driven by motor so that slide block moves on slide rail;Certainly, In the present embodiment, the drive form only with motor also it is not only limited to.
Thus, in the present embodiment, gage frame 4 can be by itself and the slidable connection of support Realizing altitude mixture control, automaticity is high, and then is favorably improved testing precision.Especially , in the present embodiment, it is possible to by the altitude mixture control of support and gage frame 4 and support can It is slidably connected to combine and together gage frame 4 is regulated to wheat canopy, save further The adjustment time, improve testing efficiency.Other technical scheme and the technical scheme phase in embodiment one With, for avoiding repeating, do not do extra elaboration at this.
