Determining measure of gaping in fish fillet item

A method of determining a measure of gaping in a fish fillet item, the method comprising the steps of:

• obtaining optical imaging data of a second area of the fish fillet item, wherein the first area and the second area are overlapping at least within an overlap area;
• determining a measure of gaping in the fish fillet item based on the
• (i) three-dimensional profile data within the overlap area, and the
• (ii) optical imaging data within the overlap area;
• obtaining three-dimensional profile data of a first area of the fish fillet item;
• wherein determining the measure of gaping in the fish fillet item comprises determining a candidate gaping area set of the fish fillet item, in which each candidate gaping area passes each of:
• a test where pass or failure is based on the three-dimensional profile data, based exclusively on the three-dimensional profile data, of the fish fillet item;
• and
• a test where pass or failure is based on the optical imaging data, based exclusively on the optical imaging data, of the fish fillet item.

A fish fillet item processing apparatus for determining a measure of gaping in a fish fillet item comprising:

• a three-dimensional profile determining device, including a camera and a line laser, for generating three-dimensional profile data of a first area of the fish fillet item;
• an optical imaging device, including a camera, for generating optical imaging data of a second area of the fish fillet item, wherein the second area is at least partially overlapping with the first area;
• and
• a processing unit, including a computer, operatively coupled to the three-dimensional profile determining device and the optical imaging device.

A non-transitory computer readable medium storing a computer program, comprising instructions which, when the program is executed by a computer, cause the computer to carry out a method comprising the steps of:

• obtaining three-dimensional profile data of a first area of a fish fillet item;
• obtaining optical imaging data of a second area of the fish fillet item, wherein the first area and the second area are overlapping at least within an overlap area;
• determining a measure of gaping in the fish fillet item based on the
• (i) three-dimensional profile data within the overlap area, and the
• (ii) optical imaging data within the overlap area,
• and/or comprising instructions to cause a fish fillet item processing apparatus for determining a measure of gaping in a fish fillet item comprising:
• a three-dimensional profile determining device, including a camera and a line laser, for generating three-dimensional profile data of a first area of the fish fillet item;
• an optical imaging device, including a camera, for generating optical imaging data of a second area of the fish fillet item, wherein the second area is at least partially overlapping with the first area;
• and
• a processing unit, including a computer, operatively coupled to the three-dimensional profile determining device and the optical imaging device;
• wherein said apparatus is arranged to execute the steps of said method.
