A photogrammetric system includes a camera installed in a movable body and including a shutter unit that moves an exposed portion across an imaging surface from one side to the other side for exposure to capture an image, a measuring device configured to measure a position at which the camera captures the image, and a photogrammetry data generator configured to extract a feature point from the image captured by the camera, calculate a feature point capture position at which the feature point is captured based on a measurement result of the measuring device and a moving time of the exposed portion, and generate photogrammetry data including the feature point capture position.
