Pose estimation is a technology that uses distance measurement data output from 3D TOF sensor B5L to estimate human skeletal points and output their coordinates using OMRON's proprietary algorithm that utilizes AI technology. From these skeletal points, it is possible to quantitatively recognize what kind of posture a person is in and to understand a person's posture, which is generally called pose estimation or skeletal estimation. As an application of pose estimation, we believe that customers can use the algorithm to analyze these skeletal points to estimate the possibility of a person falling and tumbling.
