Abstract One of the important factors that jeopardize the safe operation of the power grid is ice coating, which requires an accurate and reliable method for monitoring it. To this end, this paper is based on three-dimensional instant imaging stereo vision technology, using the three-dimensional camera equipped with LoRa module to monitor the ground wire icing. The hardware arrangement and imaging principle in the method can greatly avoid ambiguity, thereby escaping the dependence on auxiliary means such as structured light, and realize the functions of universal, real-time, long-distance and passive imaging in the field of machine vision, which can meet the needs of ice monitoring field and large field of view. The experiment proves that the method can visually observe the ice coating situation and accurately calculate the thickness of the ice coating. It has practicality and feasibility, and provides powerful technical support for the grounding wire ice monitoring work.
