<P>PROBLEM TO BE SOLVED: To accurately measure the amount of a work by using images photographed with cameras in an excavation site. <P>SOLUTION: The status of a bucket in which the bucket is at a predetermined angle by operation of a work machine, and the status of the inside of the bucket after removal of soil from the bucket are photographed with a plurality of cameras (steps S5, S11), an inside-bucket loaded-up capacity in excavation and an inside-bucket capacity after soil removal are respectively calculated from parallaxes from the photographed images (steps S6, S12), and the inside-bucket capacity is subtracted from the calculated inside-bucket loaded-up capacity to calculate a work amount of the bucket (step S13). By doing this way, even if soil adhering to the bucket remains in the bucket on the occasion of removing soil, a precise work amount subtracting that amount can be measured. Since the plurality of cameras are installed on the work machine, in this case, the measurement is performed in the excavation site without moving the hydraulic excavator to a measuring site for each measurement. <P>COPYRIGHT: (C)2009,JPO&INPIT |
