WIPO Patent Application WO/2011/058529

Kind Code:

A3

Abstract:

The invention relates to a method and system for the real-time automatic analysis of the quality of samples of processed fish meat based on the external appearance thereof, said samples travelling on a conveyor belt such that surface defects can be detected and the fish meat can be sorted according to quality standards. The invention comprises the following steps: automatically detecting the processed fish meat samples on the conveyor belt using a tracking method; capturing periodic images of the conveyor belt in order to produce a segmentation of the captured images; analysing the captured image in order to determine the shape and colour of the processed fish meat samples; counting the processed fish meat samples; and detecting surface defects on the processed fish meat samples, such as haematomas and melanosis. The system comprises: a portable device which is positioned above a conveyor belt and which includes a closed dome-type cover insulated from the surrounding environment, positioned above the conveyor belt, and an L-shaped base structure that is used to position the cover above the conveyor belt without handling same; means for storing and processing information; image-capture means; graphical user interface means for inputting pre-defined parameters and viewing results; and lighting means for maximising the uniformity of the light intensity received by the processed fish meat samples in the entire space of the image to be captured.
