Abstract:

A non-prism laser measurement system using image control is described. The device combines imaging, non- prism laser measurement, and computer control techniques to achieve an early understanding of topography and the amount of earthworks required as well as improved work safety. Consisting of CCD cameras, non-prism laser measurement equipment, rotational positioning equipment, and a computer, it is operated interactively using a keyboard or mouse. The laser is of the lowest power class, at less than 0.16 m W output, but allows measurement at distances up to 500 m with a precision of 1 cm. The system is currently in use during site preparation work for the Anan Converter Substation of Shikoku Electric Power Company, where it is assisting in the early understanding of changes in earth volume and topographical control.
