Title:
CONSTRUCTION MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/176208
Kind Code:
A1
Abstract:
Provided is a construction machine which can display various work tools, including a bucket, on a display device without causing a sense of uneasiness. A display controller modifies a first drawn figure such that a triangle having vertices of a first connection point, a second connection point, and a first monitor point in the first drawn figure is congruent with a triangle having vertices of the first connection point, the second connection point, and the first monitor point in a coordinate system on an image of the display device, thus creating a first post-modification drawn figure. The display controller positions the first post-modification drawn figure on a screen of the display device such that the positions of the first connection point, the second connection point, and the first monitor point in the first post-modification drawn image respectively coincide with the positions of the first connection point, the second connection point, and the first monitor point in the coordinate system on the image.
