Résumé :
|
A prototype fish monotoring system (fms-1000) was developed during 1984-1986. it was installed in a fish processing plant and tested in a commercial production environment. the system included a conveyor belt, a light table and a system of pneumatically controlled chutes or hgates used to route different species/sizes of fish onto appropriate filletting lines. fish were routed from the plant holding room to the filletting lines via the fms-1000 ; passing over the light table each was photographed by a video camera positioned over, identified by contour outline, assigned a lenght/weight category, and routed onto a filletting line. the chuting system and the computer software were modified during testing so that eventually the fms-1000 was able to adequately supply properly size-sorted fish to a filletting line system having a peak (day-shift) production rate of 125,000 1b. in a eight hour period. the system was used primarily on cod ; because the plant was in full production 16 hours a day it was very difficult to complete tests of the accuracy of the vision process in species recognition. recommendations for further improvments to the system were developed and the fms-1000 was removed from the plant to undergo modification.
