Description
Technical field
The utility model is related to a kind of image collecting device, more particularly, to a kind of list for spherical fruit visual selection
Camera harvester.
Background technology
In recent years, with the development and the raising of living standards of the people of agricultural science and technology, domestic and international fruit variety is more and more,
People there has also been higher requirement to the quality of fruit, carries out quality grading and size fractionation to fruit, is to meet people to water
The main method of fruit high-quality requirement, and higher profit is obtained after fruit is classified, fruit is divided at present
That selects mainly has two kinds, and one kind is artificial separation, and another sorted using fruit sorter.
Existing artificial separation fruit labor intensity is high, and efficiency is low, and sorting grade is not fine, not only wastes substantial amounts of manpower
Material resources, and add production cost；The fruit grade that existing sorted fruits device is sorted out is not fine, fruit quality,
Size, color grade are mixed and disorderly, and separating effect is poor, and the fruit quality sub-elected is poor, undoubtedly reduces the profit of fruiterer.
Nowadays fruit surface defect detection is widely used and contained great potential with quantitative analysis tech as one kind
Fruit quality classification means known together already by people, but due to the serious restriction of reliability, real-time and quantification ability,
The popularization and application of the current technology also so succeed far away and based on fields such as size, color characteristics classifications.Existing fruit point
Select the light source in vision collecting device in irradiation such as Kiwi berry equal sphere fruit, can be sent out during its collimated light beam direct projection pericarp surface
Raw spheric reflection, causes each several part uneven illumination, or even can cause portion surface area glare, so as to cause surface defect information
It is submerged in complex background, has influence on the reliability and stability of defects detection.
Patent publication No. is that CN204892407U utility models disclose a kind of fruit sorter visual selection device, is wrapped
Camera, camera lens, curved reflector, light source, frame and control system are included, the control system is connected with camera, the camera
Above frame, the camera lens is vertically installed at below camera, and the camera lens is connected with camera, and the curved reflector is consolidated
Dingan County is provided with light hole in frame on the curved reflector, the light hole is located at the underface of camera lens, the light source
In frame, positioned at the lower section both sides of curved reflector.The utility model solves existing sorted fruits light source and irradiated
There is blind area, cause to shoot that unclear, grade is mixed and disorderly for sorting, effect is poor, but the utility model is still using parallel
Light beam is radiated at pericarp surface, because fruit is spherical or similar spherical structure, can not still solve uneven illumination and fruit table
The problem of planar defect detects poor reliability, and the utility model can only obtain the image above fruit, it is impossible to obtain under fruit
The image of side, this will certainly cause the fruit of some lower section existing defects to be treated as intact fruit, so that reduce detection can
By property.
Accordingly, it would be desirable to design a new fruit vision one camera harvester, it can effectively solve the problem that because light is uneven
It is even, be easily caused spherical fruit surface defect information and be submerged in complex background, and then have influence on defects detection reliability and
The problem of stability, and the image below fruit can not be obtained, the fruit in turn resulting in some lower section existing defects is treated as
The problem of intact fruit.
Utility model content
In view of this, the purpose of this utility model is to be regarded in view of the shortcomings of the prior art there is provided one kind for spherical fruit
Feel the one camera harvester of sorting, light problem of non-uniform can not only be solved, and can detect simultaneously below fruit
