Abstract
A seine net calibration target for an image sensor can include a given set of seine nets connected to form a polygon and another set of seine nets. Each seine net of the other set of seine nets is coupled to a vertex of the polygon at a given end and coupled to a respective one of a plurality of boats at another end. The seine net calibration target can also include a plurality of light sources arranged along a top edge of the given set of seine nets and the other set of seine nets. The plurality of light sources emits light at a predetermined wavelength.

- another set of seine nets, wherein each seine net of the other set of seine nets is coupled to a vertex of the polygon at a given end and coupled to a respective one of a plurality of boats at another end;
- and
- a plurality of light sources arranged along a top edge of the given set of seine nets and the other set of seine nets, wherein the plurality of light sources emit light at a predetermined wavelength.
A seine net calibration target for an image sensor comprising:
- a given set of seine nets connected to form a hexagon;
- and
- another set of seine nets, wherein each seine net of the other set of seine nets is coupled to a vertex of the hexagon at a given end and coupled to a respective one of a plurality of boats at another end;
- and
- a plurality of floats arranged at a top edge of the given set of seine nets and the other set of seine nets, wherein each of the plurality of floats comprises:
- a plurality of light sources that emit light at a predetermined wavelength;
- and
- a controller that controls the output of the light sources.
A seine net calibration target for an image sensor comprising:
- a given set of seine nets connected to form a polygon;
- and
- another set of seine nets, wherein each seine net of the other set of seine nets is coupled to a vertex of the polygon at a given end and coupled to a respective one of a plurality of boats at another end;
- wherein each seine net in the given set of seine nets and the other set of seine nets has a plurality of light sources arranged along a top edge of the respective seine net, wherein the plurality of light sources emit light at a predetermined wavelength or a range of wavelengths and the emitted light is sufficient to saturate at least one pixel of the image sensor.
