In recent years, the performance of PTZ (Pan-Tilt-Zoom) cameras has continued to improve in terms of zoom magnification and resolution, and the accuracy of PTZ control has advanced as well. When we aim to utilize these PTZ cameras for wide-area image data acquisition, observation and measurement based on these images, we must take into account the fact that the images are time-series data and are taken at various locations at various elevation angles and magnifications. In order to utilize the data for observation and measurement, it is essential for the data viewer to be able to easily understand when and where the various images were taken. However, a problem that is more pronounced, especially with high-magnification images, is that it is difficult for the average data viewer to determine the position in the image from the captured object.
Therefore, we studied a visualization method to display images taken by a PTZ (Pan Tilt Zoom) camera in conjunction or integrated with a 3D GIS (Geographic Information System), so that anyone can easily grasp the location captured in the image.
