A bus-based visual leveling control system based on laser guidance

Abstract

The invention belongs to the technical field of machine vision and discloses a laser-guided bus-type visual leveling control system. Each module of the system adopts the field bus communication protocol to realize information interaction, and the line laser transmitter is used to emit horizontal line laser to the vision module; the vision module takes the line laser image and calculates the elevation data of the leveling plate, and transmits it to the main station module; The inclination sensor is used to collect the inclination data of the leveling plate and transmit it to the master station module; the slave station module converts the digital control quantity transmitted by the master station module into an analog control quantity, and transmits it to the servo control module; the servo control module according to The analog control adjusts the elevation or inclination of the leveling plate. In the laser-guided bus-type visual leveling control system provided by the present invention, the field bus communication protocol is used for information interaction between each module, so that while ensuring the real-time performance of the system, the complexity and cost of the system can be reduced, and it has the advantages of High scalability.

Description

technical field [0001] The invention belongs to the technical field of machine vision, and more specifically relates to a laser-guided bus-type visual leveling control system. Background technique [0002] Machine vision is a technology that uses machines instead of human eyes to extract information from images of objective things, process them, understand them, and finally use them for actual detection and control. With the gradual maturity of machine vision technology, its application is becoming more and more extensive. [0003] In machine vision technology, the traditional computer (PC)-based software integration method mainly works around the dedicated image processing software in the PC. Generally, PCI bus, TCP / IP, USB and other communication methods are used to transmit image data to the PC. be processed in. Another communication integration method based on embedded devices encapsulates visual sensors, processors, communication and other hardware together. After ima...
