Abstract
An environment cognition system for construction machinery includes a first sensor installed on an upper surface of a cabin of the construction machinery to obtain shape information on a front ground, and a second senor installed on a lower surface of a boom of the construction machinery to obtain shape information data in an excavation area. The second sensor is installed in a region that does not overlap a trajectory of a circle drawn by an end of a bucket, with the arm folded as far as possible.
Claims3
An environment cognition system for construction machinery, comprising:
- a first sensor installed on an upper surface of a cabin of the construction machinery to obtain shape information on a front ground;
- and
- a second sensor installed on a lower surface of a boom of the construction machinery to obtain shape information data in an excavation area,
- wherein the second sensor is installed in a region that does not overlap a trajectory of a circle drawn by an end of a bucket, with an arm folded as far as possible,
- wherein the first and second sensors comprise a LiDAR (Light Detection And Ranging) sensor, and
- wherein in response to a thickness of the LiDAR sensor being determined, intersection points at which the trajectory crosses an installation space formed when the LiDAR sensor moves along an installation surface on which the LiDAR sensor is to be installed are determined, an interference space is obtained by finding positions of the intersection points using an equation of a secant of the circle, and an interference-free region is determined as the installation region by excluding the interference space from the installation region.
