Document Type and Number:
WIPO Patent Application WO/2020/261634
Kind Code:
A1
Abstract:
The present invention comprises: a learning image cropping unit (403) which crops learning images from a captured image, said learning images being a portion corresponding to a first region and a portion corresponding to a second region different from the first region; an image sorting unit (404) which sorts on a per-parameter basis the learning images cropped by the learning image cropping unit (403); an image learning unit (406) which carries out machine learning using the learning images for each of the parameter sorting divisions sorted by the image sorting unit (404) and generates a reasoner; an automated learning management unit (409) which instructs the image learning unit (406) to execute the machine learning in accordance with either the number of learning images for each of the parameter sorting divisions sorted by the image sorting unit (404) or the elapsed time from the execution of the machine learning by the image learning unit (406); and a detection unit which detects a position of a boundary line from the captured image using the reasoner generated by the image learning unit (406).
