Vr wearable device and obstacle detecting method thereof

A virtual reality wearable device comprising:

• an environment capture module for capturing an external image;
• an image integration module electrically connected to the environment capture module for receiving the external image in real time as a real-time environment image, and integrating the external images captured around one circle into an initial environment image;
• a memory module electrically connected to the image integration module for storing the initial environment image;
• a detection module electrically connected to the image integration module and the memory module for detecting whether there is a different between the initial environment image and the real-time environment image, when there is a difference between the initial environment image and the real-time environment image, the detection module generates a notification signal;
• and
• a warning module electrically connected to the detection module for sending a warning signal according to the notification signal.
