Background
The national highway construction is related to the pace of economic development and national development, the road needs to be maintained after the construction is completed, potential safety hazards caused by the quality problem of the road are avoided, regular detection and maintenance of the road are required, and the machine vision detection technology is adopted as the main technology of the current road detection, namely, the automatic detection of the road surface damage is realized through automatic acquisition of a road surface image and machine identification of a road surface picture. A complete road vision detection system comprises a light source, a lens, a camera, an image acquisition card, image processing software, a monitor, a communication input/output unit and the like. The camera and the lens determine whether the system can completely and clearly shoot images, and the image acquisition card controls the camera to take pictures and determines an interface of the camera, so that the image acquisition card is an important device for coordinating the whole system. Since the object collected by the machine vision system is in a moving state, an external monitoring device is needed to monitor the movement of the object and control the camera to collect images according to the movement of the object, and the encoder is the most widely used external monitoring device.
Encoders are a type of sensor that is used primarily to detect the speed, position, angle, distance, or count of a mechanical movement. An encoder is a device that compiles, converts, and formats signals (e.g., bitstreams) or data into a form of signals that can be communicated, transmitted, and stored. The encoder converts angular displacement or linear displacement into an electrical signal, the former becomes a code disc, and the latter is called a code ruler. The encoder can be divided into a contact type and a non-contact type according to a reading mode, wherein the contact type adopts electric brush output, and an electric brush contacts a conductive area or an insulating area to indicate that the state of the code is '1' or '0'; the non-contact receiving sensitive element is a photosensitive element or a magnetic sensitive element, the state of the code is '1' or '0' by using a transparent area and a non-transparent area when the photosensitive element is adopted, and the collected physical signal is converted into a machine code readable electric signal through binary coding of '1' and '0' for communication, transmission and storage. The encoder is mainly used as a trigger signal of a linear array camera in a motion detection process in a vision system. The encoder can be used for measuring the movement speed of an object or a camera, so that the longitudinal magnification and the transverse magnification of the camera are consistent, and the information of the object is more accurately reduced. The encoder is fixed in such a way that the shell is kept still, the axle center moves along with the outside, and in a road detection vision system, the axle center needs to be fixed with the automobile wheels and keeps concentric movement.
