Description
Technical field
The utility model relates to egg processing classification technique field, relates in particular to a kind of groups incubated egg and becomes active vision detection and classification device.Specifically, the utility model is to utilize machine vision technique to gather the image of incubated egg, processes by a series of image, judges the one-tenth activity of incubated egg according to the color characteristic of incubated egg.
Background technology
The one-tenth activity of incubated egg directly has influence on the height of incubation rate, and can have influence on the quality of day old chick fowl and health status in the future, viability and production capacity.The hatching Egg―qualites is surface simple with it not only, and is as relevant in the size of egg type, egg size and egg, and in hatching process, incubation condition is also very important on the impact of kind of egg.Usually, incubation rate reaches 90% of fertile egg reaching into 85% of incubation in situation preferably; By in the hatchery, the incubation rate that minimum requirements enters incubation should be not less than 65% at present, and for fertile egg, its incubation rate should be more than 85%.And the incubation rate in actual production process is most lower than this level, and what have even pays friendly mountain lower than 65%(, 2004); This will have a strong impact on income.Moreover, the wind egg that occurs in hatching process, addled egg can breed bacteria pollute environment of hatching, thereby have a strong impact on the incubated egg of surrounding normal.Usually, planting egg all will carry out 2-3 time according to egg and reject wind egg and the work of addled egg in hatching process.Process according to egg is exactly fertility detection and the sorting of incubated egg, and purpose is the developmental state of observing the embryo, rejects wind egg, dead smart egg and addled egg, and with this foundation as the adjustment incubation condition, improves incubation rate.Therefore, the hatching of breeding eggs fertility detection is to produce the prerequisite of good poultry and the guarantee of economic benefit.
In reality hatching is produced head according to, inferior photograph and end according to often running into the embryo's of incubated egg the abnormal phenomena of mortality in three photograph egg processes, hatching early stage (head shines) embryo's lethality is approximately into 1%~3% of incubation, mid-term, (inferior photograph) embryo's lethality was approximately into 5% of incubation, later stage (end is shone) embryo's lethality is approximately into 5% of incubation, all belong to normal condition (Yu Zhihong, 2006).If surpass these scopes, the incubation condition existing problems are described.So hatching is early stage, mid-term, later stage incubated egg fertility detection no less importants all, all very important, in fact, the rejecting of middle and later periods addled egg is even more important.All be conducive to adjust and improve the environment of incubator box, more can improve hatching efficiency and hatching quality.
There is wide hatching market in China as a birds, beasts and eggs big country; Therefore the fertility detection work of incubated egg, essential.But the present fertility detection that manually carries out incubated egg according to the method for egg that also adopts of domestic most hatching enterprise.This method is subject to the impact of multiple subjectivity, objective factor unavoidably, exists to a certain extent to detect that index is unilateral, technological means falls behind, and inefficiency, the labour consumes the problems such as large, naturally is difficult to satisfy the demand of modern production.In recent years, some scholars have made the research of many explorations in this respect, yet existing research becomes active detection to study system not enough for the embryo in whole hatching stage, such as the incubated egg embryo fertility detection that has only related to early stage or mid-term not yet relates to the later stage.And the also only detection when the static state for single piece of incubated egg of research can't be applied to produce actual.Therefore, colony's incubated egg that research is applicable to the complete hatching stage of need of production becomes active online the detection and separation system, and the design one modern process unit of cover will be a very significant job.
The utility model has solved the problems referred to above exactly, makes us transfer to the hatchery to the research of the detection of incubated egg from the laboratory, is applied to production practices.
