Environment monitoring device for operating machinery

摘要

Upper viewpoint conversion processing is performed on each image (31) captured by a plurality of cameras (30) to create an upper viewpoint image (35), display images are extracted from each upper viewpoint image (35) and each extracted display image is synthesized, and an overhead image (300) centered on an image corresponding to operating machinery is created. At this time, a region of the display image extracted from each upper viewpoint image (35) is enlarged beyond the size of a standard extraction region on the basis of the established height of the mating face Z, and each extracted display image is adjusted and synthesized in the standard extraction region. In this way, any object (obstruction) present near the boundary between display images constituting the overhead image can be reliably displayed.
