Visual inspection grading device and method for survival rates of eggs incubated in groups

Abstract

The invention discloses a visual inspection grading device and a visual inspection grading method for survival rates of eggs incubated in groups, and relates to the technical field of egg processing grading. A machine vision technology is used for acquiring images of the incubated eggs, the images are subjected to a series of processing, and the survival rates of the incubated eggs are judged according to color characteristics of the incubated eggs. The device is structured in a way that the incubated eggs in standard egg trays of a hatchery are vertically arranged in egg holes of the standard egg trays; light sources with rubber rings are positioned under the incubated eggs; the standard egg trays of the hatchery are positioned on an egg machine conveyor belt; an industrial camera is positioned over the egg machine conveyor belt; a photoelectric sensor is positioned just under the egg machine conveyor belt, and is connected with the industrial camera through a data line; and the industrial camera is connected with a computer through a data line. The device and the method are high in efficiency and intelligence, and the labor intensity is reduced; and human eyes are replaced by a machine, so that the device and the method can be adapted to the modern automatic inspection industry, and have broad application and popularization prospects.

Description

technical field [0001] The invention relates to the technical field of egg product processing and grading, in particular to a visual detection and grading device and method for the activity of group hatching eggs. Specifically, the present invention utilizes machine vision technology to collect images of hatched eggs, and through a series of image processing, judges the viability of the hatched eggs according to the color characteristics of the hatched eggs. Background technique [0002] The viability of hatching eggs directly affects the level of hatchability, and also affects the quality of newborn chicks and their future health, viability and production capacity. The quality of hatching eggs is not only related to its simple external characteristics, such as egg shape, egg weight and egg size, but also the influence of incubation conditions on the eggs during incubation. Generally, the hatching rate can reach 85% of hatched eggs and 90% of fertilized eggs under better co...

Problems solved by technology

This method is inevitably affected by various subjective and objective factors. To a certain extent, there are problems such as one-sided detection indicators, backward technical means, low efficiency, and large labor consumption. Naturally, it is difficult to meet the needs of modern production.

In recent years, some scholars have made a lot of exploratory research in this area. However
