摘要： Provided is a cursor display method of displaying a cursor, indicating a focus point while being manipulatable to move, in a two-dimensional image in which sets of laser point cloud data distributed on a three-dimensional coordinate system are shown on the basis of a predetermined view point position. The cursor display method includes: performing arithmetic on a position on the three-dimensional coordinate system which corresponds to the focus point in the two-dimensional image; defining a predetermined plane graphic region, including the corresponding position and being orthogonal to a view point position direction, on the three-dimensional coordinate system on the basis of the corresponding position; dividing a view region, originating from the view point position passing through the plane graphic region, into segments on the basis of the plane graphic region; and performing non-display processing on sets of laser point cloud data placed in any one of the divided segments.
