A safety prompting method and device based on positioning of multiple body parts
By combining positioning sensors and multi-cameras, the positions of the VR device user's head, hands, and feet are located separately. Based on the relationship between these positions and the safe zone, prompts are given, which solves the problem of external threats to the safe zone where the feet are not detected in existing VR devices, and achieves more comprehensive security protection and power consumption optimization.

Abstract
The application relates to the VR technical field and provides a safety prompting method and device based on positioning of multiple body parts. A VR device acquires measurement data sent by a positioning sensor, and acquires a target depth image of a real environment collected by a multi-view camera according to a detection frame rate. Since the detection frame rate is determined according to the initial positions of the VR device and the feet in the safety area and the user posture, the accuracy of foot positioning can be improved, so as to reduce the detection power consumption of the VR device under the premise of ensuring user safety. The target positions of the upper body part and the feet are respectively positioned through the measurement data and the target depth image, the positional relationship between each body part and the safety area is acquired, safety prompting is performed when the positional relationship meets a prompting condition, the user safety is comprehensively protected, and the safety of the user is improved in the scene where the activity amplitude of the feet is large.
