Methods and systems for determining fish catches
First Claim
1. A method for estimating a total weight of a fish catch, comprising:
- capturing images of a fish catch;
the fish catch having been received on a fishing vessel;
wherein capturing images of the fish catch comprises;
capturing a first image from a first camera; and
simultaneously capturing a second image from a second camera;
identifying fishes in the images;
applying stereo-photogrammetry to obtain characteristics of each fish from the fishes;
the first camera and the second camera being configured such that stereo-photogrammetry can be applied;
identifying, using the characteristics, for each of the fishes, a species to which a corresponding fish belongs;
determining, from the images, lengths of fishes that are a part of the fish catch;
determining, from the images, a volume occupied by the fish catch; and
estimating the total weight of the fish catch based on the lengths of fishes and the volume occupied by the fish catch.

Abstract
The present disclosure is directed towards determining, at sea, the respective weights of fish species that are part of a fish catch. By way of the present disclosure, images of a fish catch are taken using triangulation techniques involving stereo-photogrammetry. According to one embodiment, a method for estimating a total weight of a fish catch includes receiving a fish catch on a fishing vessel and capturing images of the fish catch. From the images, fishes are identified and the species to which the corresponding fishes belong are also identified. Using the images, lengths of the identified fishes as well as the total volume occupied by the fish catch are determined, which can be used to estimate the total weight of the fish catch.
