Guide display device and crane equipped with same

A guide display device of a crane, comprising:

• a data processing section configured to generate a three-dimensional map of a lifting cargo, a ground surface and a ground object and a guide frame diagram representing outlines of the lifting cargo and the ground object by using point group data acquired with a laser scanner by scanning the lifting cargo, the ground surface and the ground object from above the lifting cargo;
• and
• a data display section configured to display images of the lifting cargo, the ground surface and the ground object captured by a camera from above the lifting cargo,
• wherein the guide frame diagram generated by the data processing section is displayed in a superimposed manner on the images of the lifting cargo and the ground object captured with the camera and displayed on the data display section,
• wherein the data processing section calculates a measurement region of the camera, generates a first image by capturing the three-dimensional map in the measurement region from a perspective of the camera, and generates a second image by performing a mosaic process on an image of the camera in accordance with a granularity of the three-dimensional map, and
• wherein the data processing section performs a registration process on the first image and the second image, calculates a displacement amount of the first image and the second image, corrects an installation position of the guide frame diagram with respect to the images of the lifting cargo and the ground object based on a calculated displacement amount, and displays the images of the lifting cargo and the ground object and the guide frame diagram in a superimposed manner on the data display section.
