Abstract

The invention relates to a mushroom grader based on a computer vision technology. The mushroom grader 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 a 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

Mushroom classification machine based on computer vision technique
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 cultivating champignon country the earliest in the world, also is producing country, exported country and the country of consumption of in the world mushroom maximum.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 in vain alternate, 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.Be subjected to the impact of the environmental factors 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.Wherein spend mushroom value in vain with the sky the highest, compare with normal optical face mushroom, price can differ 5-8 doubly.
The international market to the outlet mushroom classification strict requirement is arranged, 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 Lentnus edodes big country, and mushroom classification processing belongs to labour-intensive link, relies on for a long time artificial naked eyes to carry out the rejecting of mushroom color grading and breakage, lopsided mushroom.Mushroom classification labour intensity is large, labor intensive is many, and efficient is low, and effectiveness of classification is not high, for example, the output of preceding working procedure size fractionation can reach 7500kg/ days, and the output of artificial colors, defective sorting operation only is 100-120kg for each person every day for everyone, in order to mate output, need to drop into a large amount of manpowers, and affected 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, be the major issue that mushroom processing, outlet industry need to be resolved hurrily to efficient, the automatic classification of mushroom.
Surface color, shape, defective is the key character of mushroom external sort, be difficult to analyze with traditional method, development along with Dynamic Non-Destruction Measurement, utilize the Machine Vision Detection classification technique to become the more excellent implementation method of mushroom classification, not only can be automatic for mushroom, rapid classification provides brand-new approach, solve the classification difficult problem in the mushroom processing, but also be conducive to manufacture and design the automatic classification streamline, 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 for the in real time detection of mushroom quality and classification.Use machine vision technique, there are handle bacterium bottom surface and stockless cap face two sides image to gather to mushroom, the image that gathers delivered in the computer process, and result done timely discrimination according to the mushroom criteria for classification, at last discriminant information is sent to sorting unit, thereby realizes automatic classification.
The present invention is achieved by the following technical solutions:
A kind of mushroom classification machine based on vision technique comprises frame, the mushroom feed arrangement, and the mushroom turning device, the Machine Vision Recognition device, mushroom is carried sorting equipment.
A kind of mushroom classification machine based on vision technique, described mushroom feed arrangement is the device of mushroom vibrating feed.
A kind of mushroom classification machine based on vision technique, described mushroom turning device are that mushroom turns over turnback to the turning device of another face from a face.
A kind of mushroom classification machine based on vision technique, described Computer Vision Recognition device is the mushroom IMAQ, analyzes the device of processing.
It is that mass transport and the compressed air that belt roller bearing and belt consist of blows sorting equipment that a kind of mushroom classification machine based on vision technique, described mushroom are carried sorting equipment.
The present invention adopts turning device can realize that mushroom is from simultaneously translating into another side, being convenient to utilize same camera and light source chamber to obtain mushroom has handle cap face and stockless bacterium ground plan picture, to reduce the differentia influence because of the inconsistent same mushroom image that causes of the image capture environment conditions such as camera and light source.Adopt mushroom delivering sorting device, utilize the nozzle blowing out pressurised air, can fast mushroom be delivered to corresponding hopper.
