The invention belongs to the technical field of isolation knife switches, and particularly relates to a knife switch intelligent identification system and method based on a binocular vision technology, and the system comprises an image collection device, a signal conversion device, a calculation and analysis system, and a wireless transmission device. The image acquisition device is connected withthe signal conversion device through a wire. The signal conversion device is wirelessly connected with the calculation and analysis system through the wireless transmission device. In the system, a left high-definition night vision network camera and a right high-definition night vision network camera are arranged at a disconnecting link part. Therefore, bidirectional acquisition can be carried out on images of moving and static contacts of the knife switch. The calculation module is used for identifying the position of the identification target so as to obtain homonymous points, and a coordinate system is established by taking the homonymous point as the origin of coordinates to calculate the point distance between the coordinate points of the moving and static contacts of the knife switch, so that the point distance between the moving and static contacts can be calculated, the point distance calculation precision is improved, and the misjudgment probability caused by errors during direct measurement is reduced.
