technical field [0001] The invention belongs to the technical field of structural health monitoring, and in particular relates to a panoramic multi-angle binocular vision measurement system for a power transmission tower line system. Background technique [0002] Accidents of power transmission towers collapsing under strong winds occur from time to time, posing a great threat to people's lives and property. However, since transmission towers and transmission lines are highly flexible structures, they are highly coupled under wind loads. At present, it is difficult to quantitatively analyze the vibration response and force of the tower line system, which has been a difficult problem in research and design control for a long time.

[0002] Accidents of power transmission towers collapsing under strong winds occur from time to time, posing a great threat to people's lives and property

However, since transmission towers and transmission lines are highly flexible structures, they are highly coupled under wind loads. At present, it is difficult to quantitatively analyze the vibration response and force of the tower line system, which has been a difficult problem in research and design control for a long time. Unable to propose effective measures to solve the collapse of transmission towers

[0003] Due to the limitations of the on-site environment of the transmission tower line system, the use of traditional contact sensors such as acceleration sensors, displacement sensors, laser sensors or global positioning systems, etc., has been unable to meet the requirements for dynamic displacement monitoring of the transmission tower line system, thus limiting the power transmission system.
