摘要

PROBLEM TO BE SOLVED: To provide a technique capable of easily and accurately detecting the length of an object to be measured based on a captured image. SOLUTION: A fish body length measuring system has a detection unit that detects a head and a tail, which are characteristic parts of the fish body to be measured, from a photographed image of a fish body swimming in water, and a fish body to be measured. A calculation unit that calculates the length between the head and the tail, and a display control unit that displays the photographed image showing the detected feature portion and the frame surrounding the fish body to be measured on the display device.
