The present invention provides a camera recognition accuracy detection system. The system includes a recognized object, a host computer, a to-be-detected camera and an electric motor that are separately connected with the host computer, and a base board. The base board includes a first guide rail and a second guide rail, which are perpendicular to each other and have scales. The first guide rail is provided with a first slide block, and the second guide rail is provided with a second slide block. The to-be-detected camera is disposed on the first slide block. The first slide block and the second slide bock are each connected with the electric motor. The host computer controls a rotation speed of the electric motor so as to adjust a horizontal distance and a perpendicular distance between the to-be-detected camera and the recognized object and determine first coordinates of the to-be-detected camera after adjustment each time. The to-be-detected camera determines, according to a recognized object image collected after adjustment each time, second coordinates of the to-be-detected camera. The host computer determines, according to each corresponding first coordinates and each corresponding second coordinates, a recognition accuracy range of the to-be-detected camera, and determines whether the recognition accuracy range meets an accuracy requirement. The recognition accuracy range is detected accurately and reliably in a simple and convenient manner.
