Abstract
Techniques for top view fish characteristic determination are described. A stereo camera captures a stereo (e.g., left and right) image pair of water located below the stereo camera. An image of the pair may thereafter be processed to generate a corresponding undistorted image that is processed to identify a body boundary (i.e., excluding a tail portion) of a fish therein. The body boundary may be used to estimate a fork length of the fish, and the body boundary and estimated fork length may be used to determine one or more characteristics (e.g., weight and/or overall length) of the fish. The fish characteristic(s) can be used to estimate the biomass in the water below the stereo camera.
Claims24
A system comprising:
- at least one processor;
- and
- at least one memory comprising instructions that, when executed by the at least one processor, cause the system to:
- receive image data from a stereo camera positioned above water, the image data comprising left image data and right image data associated with a same timestamp;
- determine undistorted image data from one of the left or right image data;
- determine a body boundary of a fish in the undistorted image data, the body boundary excluding a tail portion of the fish;
- determine, using the body boundary, an estimated fork length of the fish;
- and
- determine at least one characteristic of the fish using the body boundary and the estimated fork length.
A device comprising:
- at least one processor;
- and
- at least one memory comprising instructions that, when executed by the at least one processor, cause the device to:
- receive image data from a stereo camera positioned above water, the image data comprising left image data and right image data associated with a same timestamp;
- determine undistorted image data from one of the left or right image data;
- determine a body boundary of a fish in the undistorted image data, the body boundary excluding a tail portion of the fish;
- determine, using the body boundary, an estimated fork length of the fish;
- and
- determine at least one characteristic of the fish using the body boundary and the estimated fork length.

A computer-implemented method comprising:
- receiving image data from a stereo camera positioned above water, the image data comprising left image data and right image data associated with a same timestamp;
- determining undistorted image data from one of the left or right image data;
- determining a body boundary of a fish in the undistorted image data, the body boundary excluding a tail portion of the fish;
- determining, using the body boundary, an estimated fork length of the fish;
- and
- determining at least one characteristic of the fish using the body boundary and the estimated fork length.
