Description
Technical field
The present invention relates to field of agricultural production technologies, are given birth to more particularly, to a kind of plant based on plant illumination image
Long status recognition methods.
Background technology
With the development of science and technology, agricultural production is rapidly changing traditional tillage system reform, modern industrial technology
, through gradually penetrating into agricultural production, agricultural technology gradually develops to the direction of more educated informationization for oneself.Especially with industry
Change horizontal raising, modern installations agricultural is come into being, and in global rapid emergence, and gradually forms fund, technology-intensive type
New high-tech industry, become most active one of the industry in the world today.
Modern greenhouse refers generally to carry out the greenhouse of batch production plant production, it is general have automatically controlled using environment, electronics
Technology, biotechnology, robot and new material etc. carry out plant anniversary quantity-produced system.Due to industrialized facility technology
The application of management means can be such that crop is grown under controllable environment.Therefore, greenhouse vegetable production is broken to a certain extent
The region of plant growth and space-time boundary, by the control of the factors such as humiture, illumination, soil, can reach be bordering on whole year can
The condition of farming can greatly increase crop growth period, improve the yield of unit area.
Since crop is more sensitive to environmental factor, environment-stress can directly be reacted on the plant forms of crop.
Such as:In the case of cucumber nitrogen stress, stem lignifying is hardened, yellow leaf;Plant is short and small when cucumber lacks phosphorus, and tender leaf can become smaller,
There is dark gray etc. in hair shaft.In current actual agricultural production management it is mostly be administrative staff rule of thumb, by visual method into
The stress of row crop diagnoses.
It is above-mentioned based on artificial diagnosis, although achieving certain effect on the basis of experience accumulation, automating
It is required that in relatively high modern greenhouse production, not only the efficiency of management is low for this subjective diagnostic method conjestured, but also regulated party
Subjective impact lacks objectivity, can not meet the requirement of automatic management than more serious.Therefore, in modern greenhouse production
Quickly and effectively the various information such as crop nutritional status and environmental factor are diagnosed using modern technological means, are greenhouses
One of automatically control with the important foundation of decision-making management.
As shown in Figure 1, to carry out plant growth shape using plant leaf and growth point image according to a kind of of the prior art
The system diagram of state identification, the system carry out the system diagram of growth conditions detection for plant image information.Within the system, only
By the leaf image information and growing point image information of plant, by extracting the characteristic parameter in the two, based on certain
Judge index and judgment criterion, show whether plant is health status.
The growth conditions for having existed the plants such as some crops based on computer vision technique in the prior art judge
Method, but these methods or the factor of consideration are excessively single, and processing is identified only for certain organs, or ignore outer
The growth effect to plants such as crops such as factor such as soil, illumination is connect, the visual monitoring to the true growing environment of plant is lacked,
And therefore cause the recognition accuracy to vegetative state not high.
Invention content
In order to overcome the above problem or solve the above problems at least partly, the present invention provides a kind of based on plant illumination
The plant growth state recognition methods of image, to effectively improve the identification to plant image data and environmental data,
To more accurately judge the growth conditions of each plant organ.
The present invention provides a kind of plant growth state recognition methods based on plant illumination image, including:S1 is based on sample
The growing environment soil characteristic information of the long-time consecutive variations image of plant and the sample plant, obtains the sample
The plant color texture coordinate of plant, and predict that the blade of target plant absorbs illumination based on the Lighting information of the sample plant
Image;S2 carries out data normalization processing, from the sample plant image after standardization to the plant color texture coordinate
Middle extraction plant organ, and light image is absorbed based on the blade, determine the light type of the target plant;S3 passes through
Analysis counts variation high-lighting of the organ specificity of the plant organ on room and time, and analyzes the target plant and determine
The light type of plan cluster, structure concern organ group and target plant grow light;S4 is based on the concern organ group, meter
Calculate each multidimensional Laplce feature of the sample plant about each plant organ;S5, based on each plant organ's
Multidimensional Laplce's feature, structure Laplce cluster core, are corresponding device by all multidimensional Laplce feature clusterings
Official classifies, and extracts the cluster index center of each organ classes;S6, it is corresponding described for each organ classes
Plant organ builds organ characteristics dictionary based on the cluster index center belonging to each plant organ;S7 is based on
Organ characteristic's dictionary and the corresponding multidimensional Laplce feature of the sample plant build and train plant organ's cluster
Conditional random field models obtain vegetative state identification model;S8 is planted based on target plant growth light and the target
The corresponding plant organ's multidimensional Laplce's feature of light image to be identified of object, using the vegetative state identification model, in advance
Survey the growth conditions variation tendency of the target plant.
Wherein, the step of S1 further comprises:S11 extracts the depth information of the long-time consecutive variations image
With the Lighting information of the sample plant sample is determined using the object identification method based on Naive Bayes Classifier
The plant position of plant;S12, the growing environment soil characteristic of plant position and the sample plant based on the sample plant
Information obtains the plant color texture coordinate of the sample plant;S13 simulates the sample Plant Leaf using higher order filter
The light-absorbing function of piece predicts that the blade of the target plant absorbs light image.
Wherein, the step of carrying out data normalization processing to the plant color texture coordinate described in step S2 is further
Including:The plant size, plant organ's feature and plant SOIL DISTRIBUTION of the sample plant are standardized respectively;Its
In, the step of being standardized to the plant size of the sample plant, further comprises:It chooses in the sample plant
Plant forms model meets the plant of established standards as standard size plant;Keep the corresponding plant image of the sample plant
The direction of characteristic vector is constant, is that the standard size plant pair is answered by the length adjustment of each plant characteristics of image vector
Plant characteristics of image vector length;Organ centered on the designated organ of the sample plant is chosen, plant tree is built, and
According to the length of the corresponding plant characteristics of image vector of the standard size plant, mobile each plant tree adjusts mobile arrow
Amount;The step of being standardized to plant organ's feature of the sample plant further comprises:With the designated organ
As the co-ordinate zero point in new coordinate reference space, mobile all plant trees;To the plant SOIL DISTRIBUTION of the sample plant
The step of being standardized further comprises:With the growing environment soil left margin of the sample plant to right margin vector
As original coordinate system horizontal axis, original coordinate system is determined;It is described with the growing environment Soil Interface center of the sample plant
The co-ordinate zero point in new coordinate reference space, constructs the coordinate perpendicular to the growing environment Soil Interface, as the new coordinate
With reference to the coordinate vertical pivot in space;The growing environment Soil Interface is rotated, the new coordinate reference space is projected into.
