The wearable device continues to acquire the current geographic coordinates in real time and uploads the current geographic coordinates to the server in real time, and the server further calculates the distance between the wearable device and the terminal. And when the distance reaches a second value, the wearable device uploads the generated second video file and picture to the server.
Furthermore, a plurality of thresholds corresponding to the distance between the wearable device and the mobile terminal can be preset, and corresponding video files can be uploaded when each threshold is reached. A corresponding video file is generated based on a distance node between the wearable device and the mobile terminal. For example, the preset threshold may be 100 meters and 200 meters, and a corresponding 100-meter video file and 200-meter video file may be generated according to the preset threshold, so that a guardian corresponding to the terminal may know an activity range and an environment of the wearable device user according to the video files.
Further, if the distance between the wearable device and the terminal exceeds a preset first value, the distance does not reach a second value, but exceeds a preset time length, it indicates that the user of the wearable device may stay in a certain place, play or be entangled by other suspicious people. The first camera of the wearable device continues to shoot the environment in front of the wearable device, and generates a corresponding video file according to a preset frequency. And a second camera of the wearable device continues to shoot the face image in the environment behind the wearable device in real time to generate a corresponding picture. And uploading the generated video file and the generated picture to a server according to a preset frequency. In case of accident, it is ensured that the guardian of the terminal can be provided with relevant clues and detailed video information as well as picture information of the suspicious personnel.
In one embodiment, the method further comprises: acquiring the activity duration in the environment; and before the distance between the terminal and the terminal reaches a first value or before the distance between the terminal and the terminal reaches a second value, if the acquisition duration exceeds a preset threshold, generating a third video file according to a preset frequency, and uploading the third video file to the server.
The activity duration of the wearable device in the current environment is obtained, when the distance between the wearable device and the terminal does not reach a first value or a second value and the activity duration of the current environment exceeds a preset threshold value, a third video file is generated according to a preset frequency, and therefore the wearable device can be guaranteed to continuously generate the video file within the preset frequency. Wearable equipment uploads the generated third video file to the server, and the video file generated by the wearable equipment can be a small video file with preset duration, so that the transmission time cannot be prolonged due to the fact that the video file is too large, and the transmission rate of the video file is further improved.
