Abstract
A map editing device capable of easily supplementing insufficient information and easily re-measuring an object that has changed. An image, a perspective projection map, a projection center and a projection angle are displayed in superposition. When a user manually changes the projection center and the projection angle, a perspective projection map after this change is generated and displayed. When a perspective projection map capable of obtaining insufficient information is determined, an imaging condition capable of obtaining the insufficient information can be determined based on the projection center and the projection angle at that time. The insufficient information can be easily supplemented if the arrangement is so made as to acquire images conforming with the imaging condition. The condition necessary for re-measurement can be determined.
