Description

Apparatus and method for real-time gait inspection using an infrared camera {APPARATUS AND METHOD OF REALTIME GAIT EXAMINATION USING INFRARED CAMERA}

The present invention discloses a technical idea of precisely measuring the movement of each joint of the human body when walking and converting it into a digital value to display it visually as a graph.

In various fields, technologies for analyzing the motion of the human body through the movement of joints have been developed.

For example, there is a motion capture technique for preventing spinal diseases aimed at correcting postures to correct an incorrect posture. It uses a small size and light weight MEMS-based wireless inertial sensor, which enables a short time-to-preparation time and an inexpensive motion capture system regardless of measurement location. Nevertheless, when using only the wireless inertial sensor, not only is it difficult to analyze from various points of view, but it is also difficult to collect accurate information in three dimensions.

On the other hand, researches on methods for reproducing human movements or analyzing the movements and grasping patterns have been actively conducted. However, a device capable of simultaneously inspecting each joint movement range when walking is attached to a large number of sensors on human joints. It is used only in specific institutions such as research institutes because only the complicated and difficult equipment for inspection is present.

Therefore, there is a need for a technical concept that can calculate the rate of change based on the movement of the subject during walking by quickly and easily recognizing the movement of the subject without minimizing the limitation of space and distance without attaching many sensors to the subject.
