摘要:AbstractAquaculture is an activity that is growing 10% a year in Brazil and still occupies less than 1% of the area reserved for fish farming, which shows the great productive potential of Brazil. With this growth, many challenges are emerging and many advances are being made. One technology they are starting to use in Brazilian fish farms is stereo cameras that can evaluate the average weight of Nile tilapia in a tank. This estimation of fish weight is based on its 3D length, but one of the most correlated information with the fish weight is its width. Thus, the objective of this work is to improve this estimation using stereo cameras by processing the cloud point of the surface of the fish. This paper shows some preliminary results that encourage further research since was obtained results similar to the methodology currently used.
