US 11,688,196 B2 · Fish biomass, shape, and size determination

Abstract

Methods, systems, and apparatuses, including computer programs encoded on a computer-readable storage medium for estimating the shape, size, and mass of fish are described. A pair of stereo cameras may be utilized to obtain right and left images of fish in a defined area. The right and left images may be processed, enhanced, and combined. Object detection may be used to detect and track a fish in images. A pose estimator may be used to determine key points and features of the detected fish. Based on the key points, a three-dimensional (3-D) model of the fish is generated that provides an estimate of the size and shape of the fish. A regression model or neural network model can be applied to the 3-D model to determine a likely weight of the fish.

Dependent claims

A computer-implemented method comprising:

determining, by a camera system, that an image that was generated by the camera system is of a fish that is at least partially occluded;
determining, by the camera system, a respective position of each of one or more key points of the fish that are visible in the image;
determining, by the camera system, a respective position of each of one or more key points of the fish that are occluded within the image based at least on the determined respective position of each of the one or more key points of the fish that are visible in the image;
and
generating, by the camera system, a weigh estimate of the fish that is at least partially occluded based on the determined respective position of each of the one or more key points of the fish that are occluded within the image;
and
providing, by the camera system, the weight estimate of the fish for output.
