Abstract
As manufacturing industries move to more flexible manufacturing systems, the demand for a more flexible automatic system increases dramatically. To deal with the particular navigation problems associated with automatic guided vehicles within such a system, a machine vision system has been developed. This vision system, which updates current vehicle position, is based on single camera, a priori knowledge about targets to be viewed, and a map of the related environment. A simple two-dimensional target has been designed to reduce the required complexity of the system for position updating. An algorithm has been developed to complete target recognition and its geometry calculation, and yield the camera position (vehicle) data. This newly developed vision system was then tested in a real industrial environment and the experimental results show that the system is reliable and robust. The accuracy on recovered position data is satisfactory for our purpose (less than five percent error on computing position data). The computing time of this vision system is less than a quarter of a second. Therefore this vision system is deemed adequate for automatic guided vehicles.
