Abstract
An environment map generating apparatus is provided. The environment map generating apparatus includes: a storage unit, a cross-sectional image generating unit, a model processing unit, an obtaining unit and an environment map generating unit. The storage unit stores a model of an obstacle. The cross-sectional image generating unit generates a cross-sectional image of a model of an obstacle at a predetermined height from a reference plane in an environment. The model processing unit generates a cross-sectional image-appended model by superimposing the cross-sectional image onto the model of the obstacle. The obtaining unit obtains an obstacle map at the predetermined height from the reference plane in the environment. The environment map generating unit generates an environment map where the cross-sectional image-appended model is superimposed in a semitransparent state onto the corresponding obstacle in the obstacle map.
