Computer vision-based method for visually monitoring rehydration of unsalted dried sea cucumbers

Abstract

The invention discloses a computer vision-based method for automatically monitoring rehydration of unsalted dried sea cucumbers. The method comprises the following steps of: 1, rehydrating pretreated unsalted dried sea cucumbers; 2, acquiring rehydration images, recording body type data of the unsalted dried sea cucumbers in real time, and forming a unsalted dried sea cucumber rehydration geometric locus formed by body type area of the unsalted dried sea cucumbers and the rehydration time in real time; 3, performing curve fitting on the geometric locus and calculating a tangent slope of the fitted curve; and 4, judging whether the tangent slope of the fitted curve meets the rehydration standard; if the tangent slope meets the standard, finishing the rehydration; and if the tangent slope does not meet the standard, turning to the step 2. In the method, the rehydration images of the sea cucumbers are acquired by using a camera; the images are transmitted to a computer for analysis processing; and the analog curve of body type changes of the rehydrated sea cucumber is fitted so as to judge whether the sea cucumbers meet the rehydration requirements.

Description

technical field [0001] This application is a monitoring method using computer vision in the deep processing of dry sea cucumber, which is a combination of modern information processing technology and deep processing of seafood. technical background [0002] Due to the inherent characteristics of sea cucumbers, the living body cannot be preserved for a long time, so it is necessary to make the living sea cucumbers into dry sea cucumbers, and rehydrate them to obtain ingredients when they need to be eaten. In 2003, my country's sea cucumber production reached 50,000 tons, of which 80% will be made into light-dried sea cucumbers. Therefore, how to effectively rehydrate light-dried sea cucumbers is very important. [0003] At present, the rehydration of light-dried sea cucumbers in my country mainly relies on manual work, and the rehydration process of light-dried sea cucumbers takes a long time. The total time of rehydration in water at three temperatures takes about 40 hours,...

AI Technical Summary

Problems solved by technology

When rehydrating in water at 50°C, it is very difficult to judge the success of rehydration. It requires experienced workers to observe and monitor for a long time to judge the body shape changes of sea cucumbers, and the labor intensity of workers is relatively high.
