Isolating switch working condition discrimination method based on echo transmission efficiency

The invention relates to a disconnecting switch working condition discrimination method based on echo transmission efficiency. The method comprises the following steps: acquiring point cloud data of a target object by using a laser radar; analyzing a target object according to the point cloud data to obtain the state of the target object; obtaining the distance between the laser radar and the target object; acquiring the surface area of the target object; calculating the echo transmission efficiency of the laser radar according to the distance and the surface area; and judging whether the state of the target object is accurate or not according to the echo transmission efficiency. The laser radar is adopted to obtain the point cloud data of the disconnecting switch, feature extraction and state judgment are performed based on the point cloud data, and the method has the characteristic of keeping high-precision monitoring in a low-light environment, is not influenced by a weak-light environment, and avoids the
