AI Technical Summary

Technical Problem

Conventional recognition technologies for hazardous work detection face challenges in accurately identifying dangerous work states without excessive processing time and false determinations, particularly in complex scenarios involving multiple work states, leading to high computational load.

Method used

A hazardous work detection system that determines the orientation of an object, such as a stepladder, and selects an appropriate hazardous work detection method from multiple models to efficiently identify dangerous work conditions by using machine learning or rule-based models, reducing processing time and false positives.

Benefits of technology

The system efficiently detects hazardous work conditions by optimizing processing based on object orientation, reducing computational load and improving accuracy by using object and skeletal information, thereby enhancing work safety.

Abstract

To provide a dangerous work detection system for efficiently detecting a dangerous work.SOLUTION: A dangerous work detection system detects a dangerous work for a person working with use of an object. The dangerous work detection system includes an arithmetic unit, and a memory unit for storing a program to be executed by the arithmetic unit. The arithmetic unit determines an orientation of the object in a first frame image of image data. The arithmetic unit selects one dangerous work detection method to determine a dangerous work state of the person in the first frame image corresponding to the orientation of the object from a plurality of dangerous work detection methods.SELECTED DRAWING: Figure 2
