Abstract

The feature of the present measuring system for position and attitude in pushing-bridge construction was analyzed and the system's primary problems were specified. Directed by all the problems and on-site requirements, a kind of photoelectric measuring system composed of CCD sensors, laser collimator and inclinometer was developed based on computer visual feedback. After the system's mathematical model has been built, the hardware work station was finished. In the process of software functional modules' development, such key technologies as video acquisition, image processing and the implementation of multiple serial ports' communication were introduced. Characterized by high accuracy, real-time, simple operation, convenient maintenance and low cost, the measuring system can substitute for the past manual measuring operation. Furthermore, the system's implementation also provides new technology for the design of other large-scale construction's measuring systems.
