Abstract

The present invention is to provide a system to take an image efficiently at a measurement accuracy which the user desires without changing the zoom factor of the camera. The system for calculating a distance 1 of the present invention includes an airborne imaging device 2 and a controller 3 . The control unit 40 of the airborne imaging device 2 performs the rectangular size acquisition module 41 and acquires the rectangular size of an object to be imaged that is computer analyzable. Then, the control unit 40 performs the distance calculation module 42 and calculates the distance between the object to be imaged and the imaging device based on the rectangular size acquired by the processing of the rectangular size acquisition module 41.

First claim

What is claimed is:

1. A system for calculating a distance, comprising:
an airborne imaging device; and
a computer that is communicatively connected with the airborne imaging device,
wherein the airborne imaging device comprises:
a rectangular size acquisition unit that acquires a rectangular size of an object to be imaged that is computer-analyzable;
a distance output unit that outputs a distance between the object to be imaged and the airborne imaging device; and
a weather data acquisition unit that acquires weather data during imaging,

wherein the computer comprises:
a distance calculation unit that calculates the distance based on the rectangular size; and
a transmission unit that transmits distance output information to the airborne imaging device to have the distance output unit to output the distance calculated by the distance calculation unit,

wherein the distance calculation unit calculates the distance between the object to be imaged and the airborne imaging device based on the rectangular size and the weather data.

2. The system according to claim 1 , wherein the distance calculation unit calculates the distance between the object to be imaged and the airborne imaging device based on the rectangular size and the resolution of the airborne imaging device.

3. The system according to claim 1 , wherein the airborne imaging device further comprises an illumination acquisition unit that acquires solar illumination during imaging, wherein the distance calculation unit calculates the distance between the object to be imaged and the airborne imaging device based on the rectangular size and the solar illumination.

4. A method performed by an airborne imaging device, the method comprising:
acquiring a rectangular size of an object to be imaged that is computer-analyzable;
acquiring weather data during imaging; and
calculating a distance between the object to be imaged and the airborne imaging device based on the rectangular size and the weather data.

5. A non-transitory computer-readable medium that stores a program for causing an airborne imaging device to execute:
acquiring a rectangular size of an object to be imaged that is computer-analyzable;
acquiring weather data during imaging; and
calculating a distance between the object to be imaged and the airborne imaging device based on the rectangular size and the weather data.
