Abstract

The invention relates to the technical field of VR, and provides a safety prompting method based on target recognition and a device thereof, and the method specifically comprises the steps: obtaining an RGB image in a field angle region collected by a binocular camera at the current moment, and the motion data, collected by an inertial sensor, of VR equipment; according to the two RGB images and the motion data, determining a multi-dimensional vector matrix representing real scene depth information in the field angle area; according to the multi-dimensional vector matrix at the current moment and the multi-dimensional vector matrix at the previous moment, determining a difference value of the multi-dimensional vector matrixes at two adjacent moments; according to the multi-dimensional vector matrix difference value, identifying whether a target object exists in the field angle area or not; and if the target object is recognized, when the target object is located in the preset safety area of the VR equipment, giving safety prompt information, so that an experiencer of the VR equipment can avoid the target object in the safety area, and the experience safety is improved while the immersion of the experiencer is not influenced.

Description

technical field [0001] The present application relates to the field of virtual reality (Virtual Reality, VR) technology, and in particular to a safety prompt method and device based on object recognition. Background technique [0002] VR devices usually have a pre-marked safe area, such as figure 1 As shown, the user performs an immersive experience in a safe area. [0003] At present, most of the spatial positioning methods based on vision are used to identify whether the experiencer has moved out of the safe area. When it is recognized that the experiencer has left the safe area, the VR device will suspend the current human-computer interaction process, and display the real field of view through the camera of the VR device. to avoid obstacles. When the target object is in the safe area, it cannot perceive the obstacles entering the safe area, which brings safety hazards to the experiencer. Contents of the invention [0004] Embodiments of the present application provi...
