Posture expert is a posture intelligent management system developed by Chuangjian Technology based on artificial intelligence, cloud computing and big data technology, combining exercise biomechanics and ergonomics, and integrating intelligent detection, risk assessment, exercise prescriptions, tracking services and customer management. Enter medical training data, build a model, and dig into the organism's implicit information (muscles, bones, risks, diseases, etc.) in depth. It has nine posture judgment algorithms such as XO-shaped leg judgment algorithm, round shoulder judgment algorithm, and pelvic roll judgment algorithm. A complete center console, an open system architecture, and the world's first intelligent posture technology based on RGB cameras support a variety of third-party application scenarios.
