Method for acquiring laser meat image by double-laser triangle method

Abstract

The invention discloses a method for acquiring a laser meat image by a double-laser triangle method. The method comprises the following steps of: 1) establishing a view field; 2) storing a gradient different between a laser meat curve and a laser plane reference curve which serves as meat thickness information to be a laser image meat thickness curve, and combining multi-frame laser meat thickness curves into a laser image according to an acquisition sequence; 3) unifying two laser images acquired by a left charge coupled device (CCD) camera and a right CCD camera to be under the same coordinate; and 4)splicing the laser images acquired at left and right angles under the unified coordinate into the same laser image to form a complete meat laser image.

Description

technical field [0001] The invention belongs to the technical field of food detection, in particular to a laser meat image acquisition method based on a double laser triangulation method. Background technique [0002] There are many unsafe factors for meat food, mainly from biological, chemical, and physical pollution. Physical pollution is mainly due to the presence of foreign matter in food. At present, meat production enterprises use large-scale machinery for slaughtering and processing, and it is impossible to completely separate the foreign matter such as metal, bone, glass, etc. from the meat itself; in automation The wear and tear of machine parts during the production process may cause problems such as chipping. These metal chips not only affect the taste and quality of the product, but also contain various harmful substances such as lead and tribute; in addition, because the animals themselves eat impurities by mistake, the impurities are embedded in the animal body...

Problems solved by technology

Physical pollution is mainly due to the presence of foreign matter in food. At present, meat production enterprises use large-scale machinery for slaughtering and processing, and it is impossible to completely separate the foreign matter such as metal, bone, glass, etc. from the meat itself; in automation The wear and tear of machine parts during the production process may cause problems such as chipping. These metal chips not only affect the taste and quality of the product, but also contain various harmful substances such as lead and tribute; in addition, because the animals themselves eat impurities by mistake, the impurities are embedded in the animal body , difficult to clean up during food production

Due to the small size of debris and impurities, it is difficult to detect with the naked eye, so it is very easy to be eaten by consumers, directly threatening the health of consumers
