Scaffold climbing safety detection method and system

The invention is suitable for the field of climbing safety detection, and provides a scaffold climbing safety detection method and system. The method comprises the steps: obtaining a displacement signal and a real-time video image of a worker hand and foot sensor on a scaffold, and carrying out detection and recognition to obtain the joint point positions of the worker in a climbing process; comparing the coordinates of the joint points and displacement information returned by the worker hand and foot sensor with a preset threshold value, and judging whether the number of the joint points with the hand and foot displacement changes of the worker is higher than the preset threshold value or not; and if the number of the joint points of which the hands and the feet have displacement changes is higher than a threshold value, triggering an alarm notification. According to the invention, the four displacement signals are combined with the video images of the hand and foot joint points to determine the displacement
