Abstract

The present invention provides a measurement system, a measurement method and a storage medium for performing various measurements such as a tsunami based on the captured images by simultaneously photographing the same photographing target area with a plurality of cameras installed at different locations. The measurement system uses a photographic unit that captures images of the same photographic target area simultaneously through multiple cameras set at different locations, including mechanical control based on angle feedback and image measurement control based on image photography and image processing, and integrates mechanical control and The two-stage control unit of the image measurement control, in the mechanical control, roughly adjusts the line of sight of each camera so that each camera can capture the image within the shooting target area through the mechanical control based on the angle feedback obtained by the angle sensor. In the image measurement control of a part of the shooting target, each camera takes a photo and feeds back the captured image to precisely control the line of sight of each camera.

Description

technical field [0001] The present invention relates to a measurement system, measurement method, and measurement program for performing various measurements of tsunamis and the like based on images captured by a plurality of cameras. Background technique [0002] Existing tsunami measurement (observation) methods can be roughly classified into two types: a method of observing a tsunami that has already reached the land, and a method of observing a tsunami before it reaches the land. [0003] (1) Observation method for tsunamis that have reached land [0004] To observe the height of a tsunami that has reached land, in addition to tide gauges installed by the Meteorological Bureau, tsunami observation equipment such as tsunami observation instruments and giant tsunami observation instruments are used. The Meteorological Bureau always observes the tide level using tide gauges and tsunami monitors, and publishes the observed data as tide observation data (preliminary value) a...
