Description
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.
