Safety guard device and method for detecting falling object

摘要

In a method for detecting a falling object using a safety guard device, a current digital image of the overhead scene is captured by an image capturing device of the safety guard device. The method detects a falling object in the current digital image, and outputs alarm messages when a falling object is detected in the current digital image and the falling object is going to hit a user of the safety guard device.

主权项

1. A computer-implemented method for detecting a falling object using a safety guard device, the method comprising:
obtaining a current digital image captured by an image capturing device of the safety guard device, and obtaining a movement direction and a movement speed of a user of the safety guard device detected by an acceleration sensor of the safety guard device; detecting a falling object in the current digital image, the current digital image comprising distance information between a lens of the image capturing device and each point in the current digital image; determining whether a detected falling object is in proximity to the user of the safety guard device according to a position of the detected falling object, the movement direction and the movement speed of the user; and outputting alarm messages by enabling one or more alarm units of the safety guard device upon the condition that the detected falling object is in proximity to the user of the safety guard device.
