1. A subsea computing device for subsea video object detection, the subsea computing device comprising:
a first data processor configured to execute object detection to:
receive a first image;
detect an object in the first image; and
assign a label and location to the object;
a second data processor distinct from the first data processor, the second data processor being configured to execute 3D reconstruction to:
receive a second image; and
process the second image and a third image to develop a 3D model comprising a 3D model component representing the object;
an object mapper communicatively coupled to the first data processor and the second data processor, the object mapper being configured to map the label to the 3D model component and output the label and 3D co-ordinates of the 3D model component;
a first camera communicatively coupled to the first data processor and the second data processor and arranged to provide the first and second images to the first and second data processors respectively; and,
a second camera distinct from the first camera having a different but overlapping field of view with respect to the first camera and being communicatively coupled to the second data processor to provide the third image to the second data processor.
