Title:
CONSTRUCTION MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/020950
Kind Code:
A1
Abstract:
Provided is a construction machine capable of detecting positional displacement of a detecting unit. A construction machine (1) is provided with: a vehicle body (1A); a plurality of distance sensors including a first distance sensor (111); a positional information acquiring unit (125); and a positional displacement detecting unit (121). The plurality of distance sensors are arranged in such a way that the detection regions thereof overlap partially. If a prescribed target object is disposed in an overlapping detection region in which the detection region of one distance sensor and the detection region of another distance sensor overlap, the positional displacement detecting unit (121) detects positional displacement of at least one of said one distance sensor and said other distance sensor in the vehicle body (1A) by comparing positional information of the target object acquired by the positional information acquiring unit (125) from distance image data from said one distance sensor with positional information of the target object acquired by the positional information acquiring unit (125) from distance image data from the other distance sensor.
