Abstract
A crane operation assistance system includes: a scanning-type distance meter capable of measuring a distance and an angle between the distance meter and an object under a range of movement of a movable body that can hoist a container and move in a horizontal direction; and object height distribution data making means for making, based on the information measured by the distance meter, object height distribution data that is data indicating a distribution of heights of objects under the range of movement of the movable body. If a blind spot for the distance meter has occurred, the object height distribution data making means revises data of object heights in the zone of the blind spot based on data of an object height at a point that is farthest from the distance meter in a imaginary containers presence zone having an overlap with the zone of the blind spot.
