Document Type and Number:
WIPO Patent Application WO/2022/138224
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a travel path photographing system that suppresses the capacity crunch of a recording device and a method for controlling the travel path photographing system. For this purpose, this travel path photographing system comprises a photographing device for photographing the neighborhood of a travel path, a recording device for recording the travel path neighborhood image photographed by the photographing device, and a control unit. The control unit identifies an identification mark from the travel path neighborhood image and controls the recording of the travel path neighborhood image to the recording device, on the basis of the information acquired from the identification mark. The control unit also identifies a start indication identification mark that indicates the start of recording, and starts recording the travel path neighborhood image to the recording device. The control unit also identifies an end indication identification mark that indicates the end of recording, and finishes recording the travel path neighborhood image to the recording device.
