Title:
CONSTRUCTION MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/034086
Kind Code:
A1
Abstract:
Provided is a construction machine in which positional displacement of a detection unit can be detected. A construction machine (1) is provided with a boom (15), an operation room (31), a distance sensor (110), a positional displacement detecting unit (121), a storage unit (124), and a position information acquiring unit (125). The distance sensor (110) has a prescribed field of view and acquires distance image data indicating a distance distribution in the surrounding environment of the operation room (31). The storage unit (124) stores initial position information about the boom (15). When the boom (15) has the initial orientation again after initial setting, the positional displacement detecting unit (121) compares comparison position information about the boom (15) acquired from the distance image data by the position information acquiring unit (125) with the initial position information about the boom (15) stored in the storage unit (124), such that positional displacement of the distance sensor (110) with respect to the operation room (31) is detected.
