A gas insulated switchgear discharge fault optical identification method is characterized by comprising the following steps: acquiring historical optical information of GIS partial discharge; converting the historical optical information into first point cloud data; establishing a GIS partial discharge optical model according to the first point cloud data; slicing the GIS partial discharge optical model based on the space coordinates, and generating a source optical irradiation graph; gIS partial discharge optical signals are collected, and a target optical irradiation graph is generated; and the target optical irradiation image is identified by registering the target optical irradiation image with all the source optical irradiation images. 一种气体绝缘设备放电故障光学识别方法，其特征在于，包括：获取GIS局部放电的历史光学信息；将所述历史光学信息转化成第一点云数据；根据所述第一点云数据建立GIS局部放电光学模型；基于空间坐标对GIS局部放电光学模型进行切片，并生成源光学辐照图；采集GIS局部放电光学信号，并生成目标光学辐照图；通过将目标光学辐照图与所有的源光学辐照图进行配准，对目标光学辐照图进行识别。
