Abstract: Provided is an object measurement device for measuring the shape of an object by recognizing the object using a machine learning model, automating determination of an edge detection direction and determination of a region for performing edge processing, and performing highly accurate edge extraction in units of sub-pixels, for example. An object measurement device according to the present invention comprises: an object recognition unit that recognizes an object in an image by inputting an acquired image as input data into a trained model, and outputs a region of the object as a recognition result; an edge detection direction determination unit that determines an edge detection direction for the region of the object recognized by the object recognition unit; an edge processing region determination unit that determines an edge processing region for the region of the object recognized by the object recognition unit; and an edge detection unit that performs edge detection in the edge detection direction determined by the edge detection direction determination unit, for the edge processing region determined by the edge processing region determination unit.
