博士 === 國立成功大學 === 交通管理(科學)學系 === 84 === The results of accident reconstruction and in-depth investigation are seriously influenced by the correctness and completeness of accident data collection at the scene. In the present, the tasks of accident investigation and data collection at the scene are performed by the policemen, always resulting in some data missing and mistaken measurements. The purpose of this research is to develop a low-cost, time-saving, high applicability, and high accuracy method for reconstructing the accident scene to solve their drawbacks of the developed methods which have been highlighted by the literature''s review. This study employs an at-scene experiment method cooperated with the computer graphical operation system thus developed to validate the adquency of a so-called pseudo-maker setting method, and its applicability was demonstrated by the case study on the actual roadway. The pseudo-marker setting method is a newly single- image photogrammetry method which is based on the geometrical theory, and combines the theory of computer graphics to reproduce the accident scene by the techniques of interactive computer graphic and digital terrain simulation. In theory, it partially solves the problems of how to determine the heights of the imaged points on single-photos. In application, the operational criteria for photographing the accident scene have thus been proposed in cooperation with the developed method to collect the accident scene data effectively. Employing the developed method to collect the accident scene data not only can preserve the correctness and completeness of accident data, but also can solve the problems generally incurred in accident investigation and data collection at the scene.
