INFORMATION PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/208538
Kind Code:
A1
Abstract:
Provided is a framework for referring to previous work content during work related to a crop. A work content recording unit (101) records work content and the like that is input. On the basis of an acquired image of a crop region, an index calculation unit (103) calculates an index indicating the state of growth of a crop captured in the image. On the basis of the calculated index (NDVI) an index map generation unit (104) generates an index map showing the state of growth of a crop in a field. A growth information recording unit (105) records the generated index map and the like as growth information. A similarity calculation unit (107) calculates a value representing a degree of similarity of a change over time in the indices for a specified field (a field in which a worker is working) and another field. A work content extraction unit (106) extracts work content that has been carried out in relation to a crop region for which the degree of similarity represented by the calculated value is equal to or greater than a prescribed level.
