内容記述タイプ Abstract
内容記述 In the past, a large accurate image scanner was used for map digitizing. The image scanner is so expensive that it is difficult to use in general. Nowadays, digital camera with 10 mega pixels can be used in many fields. In the future, such digital camera will be able to replace the image scanner. Therefore, it is important to consider an accuracy of map digitizing by using digital camera. In this study, paper map was prepared for the experiment. In the paper map, four control points and two validation points were allocated. The paper map with transparent plastic board was taken by the digital camera. Coordinates of the control points were extracted 20 times by visual interpretation. And coordinates transformation was established by two-dimensional projection transformation. Then coordinates of validation points can be calculated by the transformation. And this calculated coordinates of validation points were compared with true points. As a result, coordinate of validation points had approximately 1mm error. If distortion by the transparent plastic board is eliminated, the accuracy will be improved.
