要約
(EN)

Provided is an image analysis distance information provision system, and the system includes: a computer and an imaging device. The control unit of the computer is configured to perform the following steps according to an image of an object captured by the imaging device: determining the type of the captured object; calculating the actual length of the captured object per unit length of the image of the captured object; calculating the shooting range of the image of the captured object according to the calculation result; and estimating the distance from the imaging device to the captured object according to the calculated shooting range.
