（1）, determine take photo by plane height, vertically shoot pear tree to be identified, obtain the top view of pear tree to be identified；
（2）, determine standard a century pear tree, identical take photo by plane high perpendicular shooting standard a century pear tree, obtain standard a century pears
The top view of tree；
（3）, using convolutional neural networks, from step（1）All single pear trees to be identified are partitioned into obtained top view
Top view, from step（2）The top view of standard a century pear tree is partitioned into obtained top view；
（4）, to step（3）The top view of obtained all single pear trees draws two concentric circles respectively, wherein first concentric circles
Comprising pear tree trunk, second concentric circles includes pear tree trunk and the first side shoot；
（5）, according to shadowing method principle, in step（4）In each single pear tree top view in second concentric circles subtract the
One concentric circles, reuses binarization method, obtains class the first side shoot top view of each single pear tree, wherein to be identified
What single pear tree top view obtained is class the first side shoot top view of pear tree to be identified, is obtained from standard a century pear tree top view
It is class the first side shoot top view of standard a century pear tree；
（6）, by class the first side shoot top view of single pear tree to be identified, class the first side shoot top view with standard a century pear tree
It is compared, the pear tree to be identified that the first side shoot area is more than standard a century pear tree the first side shoot area is century-old pear tree.
Described is a kind of based on the pear tree a century age of tree method for quickly identifying taken photo by plane, it is characterised in that：The step（1）
In, according to the video memory amount of server video card, unmanned plane height is determined, vertically shoots the top view of pear tree to be identified.
Described is a kind of based on the pear tree a century age of tree method for quickly identifying taken photo by plane, it is characterised in that：Step（1）Middle vertical view
The pear tree of 20 ± 2 is included in figure.
Described is a kind of based on the pear tree a century age of tree method for quickly identifying taken photo by plane, it is characterised in that：Step（2）Determine
Standard a century pear tree, the diameter of its first side shoot is representative, i.e. the diameter of the century-old side shoot of pear tree first of the overwhelming majority all should
More than or equal to the diameter of standard a century the first side shoot of pear tree.
The present invention is not suitable for the problem of century-old age of tree of a wide range of pear tree of identification for prior art, there is provided one kind is based on
The pear tree a century age of tree method for quickly identifying taken photo by plane, its method and step clear and definite, reasonable in design and realization is convenient, for right
In the area for possessing a large amount of pear trees, the century-old pear tree therein that can quickly identify.
Compared to prior art, the present invention has advantages below：
First, based on the thought of Analog Reasoning method, the wherein super century-old age of tree can be quickly identified to a large amount of pear trees, solve existing side
Method can not quickly identify the problem of century-old age of tree of a wide range of pear tree.
Second, the data main source used can both be shot using unmanned plane, can also directly be bought from picture of taking photo by plane
Satellite photo, reduce the difficulty for obtaining data.
Brief description of the drawings
Fig. 1 is the inventive method FB(flow block).
Embodiment
As shown in figure 1, it is a kind of based on the pear tree a century age of tree method for quickly identifying taken photo by plane, comprise the following steps：
（1）, determine take photo by plane height, vertically shoot pear tree to be identified, obtain the top view of pear tree to be identified；
In this step, typically carry out shooting image using unmanned plane, unmanned plane highly, according to the video memory amount of server video card,
The height of the pear tree of 20 or so is included in a general top view, vertical shooting to be identified the pear tree of the century-old age of tree
Top view.
In this step, according to the video memory amount of server video card, unmanned plane height is determined, vertically shoots pears to be identified
The top view of tree.
The pear tree of 20 ± 2 is included in this step, in top view.
（2）, determine standard a century pear tree, identical take photo by plane high perpendicular shooting standard a century pear tree, obtain standard hundred
The top view of year pear tree；
In this step, it is desirable to determine standard a century pear tree, mainly require that the diameter of its first side shoot is representative, i.e., it is big absolutely
Partly the diameter of the century-old side shoot of pear tree first all should be greater than or the diameter equal to standard a century the first side shoot of pear tree.
（3）, using convolutional neural networks, from step（1）All single pears to be identified are partitioned into obtained top view
The top view of tree, from step（2）The top view of standard a century pear tree is partitioned into obtained top view；
In this step, training set of images is made, using Caffe frameworks, training set covers the pear tree top view for having obvious characteristic, instruction
Practice Faster RCNN models, the figure of segmentation is changed to circle, is partitioned into the top view of all pear trees.
（4）, to step（3）The top view of obtained all single pear trees draws two concentric circles respectively, wherein first same
Heart circle includes pear tree trunk, and second concentric circles includes pear tree trunk and the first side shoot；
（5）, according to shadowing method principle, in step（4）In each single pear tree top view in second concentric circles subtract the
One concentric circles, reuses binarization method, obtains class the first side shoot top view of each single pear tree, wherein to be identified
What single pear tree top view obtained is class the first side shoot top view of pear tree to be identified, is obtained from standard a century pear tree top view
It is class the first side shoot top view of standard a century pear tree；
（6）, by class the first side shoot top view of single pear tree to be identified, class the first side shoot top view with standard a century pear tree
It is compared, the pear tree to be identified that the first side shoot area is more than standard a century pear tree the first side shoot area is century-old pear tree.
