A position measurement system includes: an image data acquisition unit that acquires first image data photographed by a first camera of a first stereo camera provided at a work machine and second image data photographed by a second camera of the first stereo camera; a stereo measurement unit that executes stereo measurement on the basis of the first image data, the second image data, and parameters related to the first camera and the second camera; a first adjustment unit that changes at least a part of the parameters to adjust a stereo ratio of first disparity image data subjected to stereo measurement; and a second adjustment unit that changes at least a part of the parameters to adjust a scale of first three-dimensional data obtained from the first disparity image data.

Position measurement system, work machine, and position measurement method

A posture calculation device of working machinery includes: a measuring device configured to detect an angle speed and acceleration; a posture angle calculation unit configured to obtain a posture angle of the working machinery from the detected angle speed and the detected acceleration; a first complementary filter to which a first cutoff frequency is set and configured to decrease a noise included in the obtained posture angle to output a first posture angle; a second complementary filter to which a second cutoff frequency different from the first cutoff frequency is set and configured to decrease a noise included in the obtained posture angle to output a second posture angle; and a switching unit configured to switch between the first posture angle and the second posture angle to output the first posture angle or the second posture angle according to a state of the measuring device.

A control system comprising a position information generation unit configured to operate three modes to output position information:

Control system of work machine and work machine

A construction machine control system controls a construction machine including a traveling device, a work machine having a working tool, and a swing structure to which the work machine is attached and which is attached to the traveling device to swing with respect to the traveling device. The construction machine control system includes a position detection device that detects a first position which is a position of a partial portion of the construction machine and outputs the first position as first position information; a state detection device that detects and outputs operation information indicating an operation of the construction machine; and a processing device that calculates a second position corresponding to the position of the partial portion using the first position information and the operation information and calculates a position of at least a partial portion of the work machine using second position information.
