Abstract
The utility model relates to a mushroom grading machine based on a technology of computer vision. The machine comprises a mushroom charging device, a turn-over device, a computer vision identification device and a mushroom conveying and sorting device. When the machine is used, mushrooms pass through the mushroom charging device and enter the turn-over device which is used for turning over the mushrooms in sequence, so that two images of stiped mushroom bottom surfaces and sessile mushroom cover surfaces of the mushrooms are acquired by a single charge-coupled device (CCD) camera in the same light environment, a computer processes the mushroom image information and makes grading judgment so as to acquire a mushroom quality detection and comprehensive grading signal; and simultaneously the grading signal is converted into the corresponding control signal to drive the corresponding nozzle to work and convey the mushrooms to the corresponding containers; and therefore, the mushroom quality is automatically detected, and the mushrooms are graded.
Description
Technical field
The present invention relates to a kind of mushroom classification machine, relate in particular to that a kind of mushroom based on computer vision technique detects in real time, automatic grader.
Background technology
Mushroom fragrance is unique, is of high nutritive value, and have the laudatory title of " mountain delicacy ", is one of modal edible mushroom.Its NATURAL DISTRIBUTION zone is in the southeast, Asia, and China is artificial in the world cultivating champignon country the earliest, also is producing country, exported country and the country of consumption of mushroom maximum in the world.In the mushroom growth process; Under suitable temperature, humidity, illumination, wind speed and temperature difference condition, epidermal cell is asynchronous with the meat cell division, and the too fast meat cell of the speed of growth bursts epidermal cell; Make cap be full of cracks form the decorative pattern of brown alternate in vain, chrysanthemum shape, thereby form flower mushroom.The flower mushroom cap is plump, fine and tender taste, and beautiful appearance, economic worth is the highest, is the treasure in the mushroom, at home and abroad on the market, is well received by consumers.Receive Effect of Environmental such as physiological property and illumination, the temperature difference; Even also there is very big difference in same batch of its surface color of mushroom that goes out canopy of same kind; According to what of the white decorative pattern in cap surface, mushroom can be divided into day spend mushroom in vain, spend mushroom in vain, camellia mushroom and four grades of light face mushroom.It is the highest wherein to spend mushroom value in vain with the sky, compares with normal optical face mushroom, and price can differ 5-8 doubly.
There is strict requirement the international market to the classification of outlet mushroom, and in order to guarantee to export the mushroom quality, high quality and favourable price by the level price, is increased economic efficiency, and must carry out classification to the mushroom raw material that color mixes.
China is mushroom big producing country, and mushroom classification processing belongs to labour-intensive link, relies on artificial naked eyes to carry out the rejecting of mushroom color grading and breakage, lopsided mushroom for a long time.Mushroom classification labour intensity is big, and labor intensive is many, and efficient is low; Effectiveness of classification is not high, and for example, the output of preceding working procedure size fractionation can reach 7500kg/ days; And the output of artificial colors, defective sorting operation is merely 100-120kg for each person every day for everyone, in order to mate output, needs to drop into great amount of manpower; And influenced by workman's subjective factor, and effectiveness of classification and uniformity are poor, and the classification quality can not get ensureing.Labourer's wage cost has determined the production cost of mushroom largely; Along with labor cost improve constantly and the international market to the more and more stricter requirement of mushroom quality, to mushroom efficient, classification is the major issue that mushroom processing, outlet industry need to be resolved hurrily automatically.
Surface color, shape, defective are the key characters of mushroom external sort, are difficult to analyze with traditional method, along with the development of Dynamic Non-Destruction Measurement; Utilize the Machine Vision Detection classification technique to become the more excellent implementation method of mushroom classification; Not only can solve the classification difficult problem in the mushroom processing, but also help manufacturing and designing automatic graded pipelining for mushroom is automatic, rapid classification provides brand-brand-new way; This is to raising labour productivity; Cut down finished cost, improve China's mushroom competitiveness in the international market, promote the sustainable development of mushroom industry and be of great practical significance.
Summary of the invention
The object of the present invention is to provide a kind of online detection and hierarchy system that is used for detection in real time of mushroom quality and classification.The utilization machine vision technique; There are handle bacterium bottom surface and stockless cap face two sides image to gather to mushroom; The image of gathering delivered in the computer handle; And result done timely discrimination according to the mushroom criteria for classification, be sent to sorting unit to discriminant information at last, thereby realize automatic classification.
The present invention realizes through following technical scheme:
