METHOD AND APPARATUS FOR WORK QUALITY CONTROL
First Claim
1. A method for work quality control of a worker in work where repetitive operation is performed, the method comprising:
- an image data acquisition step of acquiring image data on the work captured;
a worker position recognition step of recognizing a position of the worker from the image data;
a prediction model construction step of acquiring a prediction model that is statistically constructed from past path data on the worker, past intermediate quality data, and past final quality data; and
an unusual worker position determining step of substituting the position of the worker recognized in the worker position recognition step into the prediction model to determine whether a position of a target worker is a usual position or an unusual position.

Abstract
A method for work quality control of a worker in work where repetitive operation is performed which includes: a model construction step of statistically constructing, from past path data of the worker, past intermediate quality data on a product to be subjected to the work, and past final quality data on the product to be subjected to the work, a prediction model that receives the path data and the intermediate quality data and outputs the final quality data; a worker position recognition step of recognizing a position of the worker from image data on the work captured; and an unusual worker position determining step of substituting the position of the worker recognized in the worker position recognition step into the model constructed in the model construction step, to determine whether the position of the target worker is a usual one or an unusual one.
