The invention discloses front and back anti-fog detection equipment, and relates to the technical field of detection equipment. The equipment comprises a camera, an angle adjustment rotating shaft, asupporting seat, a first reflection mechanism, a second reflection mechanism, and anti-fog mechanisms. The camera is disposed on the supporting seat through the angle adjustment rotating shaft, and the first reflection mechanism and the second reflection mechanism are installed at two sides of the camera, and the anti-fog mechanisms are respectively disposed on the first and second reflection mechanism. The first and second reflection mechanisms respectively comprise a primary damping rotating shaft, a worm, a secondary damping rotating shaft and a reflector, wherein one end of each worm is connected with the supporting seat through the primary damping rotating shaft, and the reflector is connected with the worm through the secondary damping rotating shaft, and is installed in front of a side of the camera. The equipment increases the detection area of a single probe, and improves the adaptability.
