Title:
OBJECT RECOGNITION DEVICE, OBJECT RECOGNITION SYSTEM, AND OBJECT RECOGNITION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/065413
Kind Code:
A1
Abstract:
[Problem] To carry out highly precise object recognition in a stable manner while reflecting changes in an imaging environment. [Solution] An object recognition method in which an imaging unit (imaging stand) on which an object (product) is to be arranged is photographed using a camera, and an object recognition machine learning model is used to recognize an object included in the captured image, wherein the object recognition machine learning model is constructed on the basis of learned model data, which is generated by carrying out a learning process using an image obtained by combining a background-less object image and a learning-use background image in which the imaging unit is imaged in a state in which the object is not arranged thereupon, and at a prescribed timing a determination is made regarding whether an update process related to the object recognition machine learning model is required. When the update process is required the camera is made to carry out a process for reacquiring a learning-use background image in which the imaging unit is imaged in a state in which the object is not arranged thereupon, and the learning process is carried out again using, as the learning data, a learning-use object image obtained by combining the background-less object image and the reacquired learning-use background image.
