Description
Technical field
The present invention relates to a kind of machine vision device, be specifically related to a kind of corn kernel quality vision inspection apparatus.
Background technology
Agricultural and food industry and people are lived closely coupled, and applied research relevant to these means of livelihood in recent years is not
Count its number.And at agriculture field, China be Maize Production and consumption big country, gross annual output amount up to about 1.2 hundred million tons, Semen Maydis simultaneously
In addition to edible, also serve as feedstuff and the raw material of industry, the corn kernel of high-quality be improve yield in agricultural and industrial processes,
Efficiency and the guarantee of quality.Therefore, actively improve corn quality, it is thus achieved that its quality quickly detects, differentiate, classification, the most former
Reason and method, be preferably to develop China's Grain Development and the needs in commerce and trade market, is also that agricultural reproduction is the most crucial
Factor.
At present, China's existing corn quality evaluation criteria is all using unit weight, impurity and defect grain etc. as important
Discrimination standard.Detection method currently mainly is to use hand picking method to detect corn kernel quality.Hand picking method needs
Human eye stares at thickly dotted corn kernel on streamline constantly, and labor intensity is big, owing to artificial range estimation is inevitably subject to
The impact of the factors such as the vision of individual, emotion, light, with the biggest individual subjectivity, so examination criteria is difficult to unified, inspection
Survey efficiency is low, sorting difference is big, adds that site environment noise and corn kernel itself are reflective, and workman is the most tired.This detection
Method is the most time-consuming takes a lot of work, and is difficult to ensure that again detection quality, needs use machine vision technique efficient, automatic badly and realizes corn kernel
Quality detects automatically.
Another kind of main stream approach is weight test method, distinguishes qualified and substandard product by detection product weight, but
It is production line balance that corn kernel produces, and the method is easily caused flase drop and missing inspection by production line machinery vibrations interference, and cannot
Detect normal niblet and impurity, therefore, it is difficult to be widely popularized.
Machine vision is also a kind of technological means that corn kernel Quality Detection is conventional, but yet suffers from deficiency: (1) adopts
When carrying out corn kernel detection by machine vision, it is often necessary to manually put or use on hardware device fixation holes method
Realizing single grain region recognition, but manually put and take time and effort, fixation holes method also is difficult to ensure that single grain is put accurately,
If hole design is improper results even in seed breakage；(2) often extract a large amount of characteristic parameters such as area, most advanced and sophisticated point, the centre of form etc. to make
For evaluation index, but when photographic head shooting distance changes, these features can change, thus cause accuracy of detection
Reduce.
The invention have effective effect that: make sample tiling separately by jitter sources and material scraping plate, even if still there being adhesion
Situation, only need to do part dividing processing, the most just can avoid the damage that hardware device causes when separating sample.
Inquired about by Patents, be found to have following open source literature:
Patent " household cereal quality inspection device and detection method " [application number CN201310563704.5] discloses one
Planting device and the detection method using corn escaping gas to carry out Quality Detection, this device sucks detection gas by detection probe
Body, uses cascade bistable-state random resonance system to process, carries out mating to judge whether corn goes mouldy with the threshold value set.
The method is high for environmental requirement, and can not detect the corn of appearance defect.
Patent " automatic checkout system of solid grain " [application number CN201520438544.6] discloses a kind of solid seed
The automatic checkout system of grain, system includes: seed sample introduction tank, gear unit, photoswitch, rotating disk, the first motor, signals collecting
Unit and controller, the program is by the cooperation between each parts so that the full-automation to solid grain detection.The program makes
With spectral technique seed carried out information processing, and non-usage machine vision technique；Additionally, the program uses rotating disk and baffle plate to make
Seed becomes string and processes, a seed can only be processed every time, processing speed is slow, and the present invention uses machine vision,
Disposably multiple seeds can be processed, and employ jitter sources and material scraping plate so that seed tiling is the most overlapping.
Patent " a kind of grain unsound grain with secondary light source detects plate " [application number CN201520246581.7] profit
The front light that the backlight provided with mainboard and desk lamp provide, it is provided that various visual angles and omnibearing light conditions, in order at grain seed
Clearly display outward appearance and the details of grain unsound grain on grain detection plate, in grain seed detection plate, be configured with auxiliary simultaneously
Equipment and grain unsound grain collection of illustrative plates and the panel of the data of parsing, for reviewer nearby with reference to comparison.The program does not has
There is use automatic transmission mechanism, and do not use machine vision technique automatically to detect.
Summary of the invention
Present invention aim to overcome that the deficiencies in the prior art, especially solve existing corn kernel Quality Detection means and lack
Weary automatic detection device, be difficult to automatically tile the problems such as sub-material.A kind of corn kernel quality vision inspection apparatus is provided, should
Device makes sample tiling separately by jitter sources and material scraping plate, even if still there being adhesion situation, only need to do part dividing processing,
The most just the damage that hardware device causes can be avoided when separating sample, it is achieved efficient corn kernel quality detects automatically.
