AI Technical Summary

Technical Problem

Existing SPECT imaging equipment's human motion monitoring system suffers from severe dependence on specific devices, poor compatibility, and an inability to adapt to changes in patient body shape and camera installation position. This leads to inaccurate identification of occlusion states, frequent misjudgments, and an inability to meet the reliability requirements of clinical imaging.

Method used

By employing a multi-camera collaborative deployment, and through image acquisition, processing, status recognition, and motion detection modules, it dynamically identifies occlusion status based on human ROI feature parameters, achieving pure visual analysis, eliminating the communication dependence on SPECT equipment, and adapting to patient body shape and camera installation position.

Benefits of technology

It improves the accuracy of occlusion detection and motion detection, reduces motion artifacts in SPECT imaging, lowers deployment costs and adaptation difficulty, and ensures image quality.

Abstract

This application discloses a human motion monitoring system, method, device, and storage medium. In this human motion monitoring system, an image acquisition module acquires N consecutive frames of images of the patient on a diagnostic bed using multiple cameras. An image processing module extracts the Region of Interest (ROI) of the patient in each frame, determining the area features of individual frames and integrated ROIs. A state recognition module determines the occlusion state of each camera based on these features. A motion detection module dynamically determines the human motion energy value for cameras with no or partial occlusion. An alarm module combines the occlusion state with the human motion energy value to issue an alarm when preset conditions are met. This solution employs pure visual analysis, does not rely on internal SPECT equipment data, and has the advantages of flexible deployment and strong compatibility. It can effectively identify occlusion states and accurately detect patient movement, helping to reduce motion artifacts in SPECT imaging and ensuring image quality.
