Paper Abstract

In this paper, we describe an effective method for fast checking the quality of digital orthoimages. In order to ensure the accuracy and precision of digital orthoimages (DOM) before putting into database, we consider metadata, coordinate data, geometry accuracy, and histogram quality of images as evaluating rules. Template matching is used in Metadata inspection. Coordinate data inspection is based on the relation between the standard file name of maps and coordinates of maps. Image matching technique is performed in geometry accuracy inspection. Image histogram quality is evaluated by the normal distributing curve characteristic. The method is tested feasible in applications for checking the quality of digital orthoimages.
