WORK MACHINE MEASUREMENT SYSTEM, WORK MACHINE, AND MEASURING METHOD FOR WORK MACHINE

A work machine measurement system includes an image acquisition unit that acquires an image of a work target captured, while a swinging body of a work machine is swinging, by an image capturing device mounted on the swinging body, a three-dimensional position calculation unit that calculates a three-dimensional position of the work target based on the image, a swing data acquisition unit that acquires swing data about the swinging body, a determination unit that determines whether or not the swing data satisfies a predefined swinging condition and an output unit that outputs a swinging instruction signal based on a result of the determination by the determination unit.
