Crane information display system
This crane information display system is provided with a terminal device having a camera and captures an image of a crane with the camera to obtain a camera image, said crane information display system comprising: a crane detection unit that detects the orientation of the crane in the camera image; an information processing unit that identifies the position and posture of the crane in the coordinate system of the camera image; a working capacity calculation unit that calculates the working capacity of the crane on the basis of the information relating to the crane inputted to an input unit; and an image display unit that converts the working capacity of the crane into three-dimensional image information corresponding to the position and posture of the crane, overlays the image information on the camera image, and displays the same.
1. A crane information display system that is provided with a terminal device having a camera and captures an image of a crane with the camera to obtain a camera image, the crane information display system comprising:
a crane detection unit that detects the crane in the camera image based on image information of the camera image;
an information processing unit that identifies a position and a posture of the crane in a coordinate system of the camera image based on an orientation of the camera with respect to the crane identified from the crane in the camera image, a position of the camera in a real space indicated by a first satellite positioning signal reception unit mounted on the camera, and a position of the crane in a real space indicated by a second satellite positioning signal reception unit mounted on the crane;
a working capacity calculation unit that calculates a working capacity of the crane based on information relating to the crane inputted to an input unit; and
an image display unit that converts the working capacity of the crane into three-dimensional image information corresponding to the position and the posture of the crane identified by the information processing unit, overlays the image information on the camera image, and displays the overlaid image.
