  • Publication number: 20250019215
    Abstract: A cargo handling system includes: a first detection unit configured to detect a cargo on a pallet held by a fork of a forklift as a loaded state together with the pallet using at least one type of sensor before cargo handling work is started; a first abnormality determination unit configured to determine whether the loaded state detected by the first detection unit is abnormal; a second detection unit configured to detect a work situation using a plurality of types of sensors after the cargo handling work is started; and a second abnormality determination unit configured to determine whether the work situation detected by the second detection unit is abnormal.

  • Patent number: 10527424
    Abstract: An angle offset judging device (1) includes: an azimuth histogram generating section (126) for obtaining an appearance frequency of estimated azimuths; and an evaluating section (127) for making an evaluation of whether or not the appearance frequency thus obtained shows a tendency which is observed in a case where an azimuth is properly estimated under a binding condition concerning an advancing direction of a movement of a moving body.

  • Patent number: 7995801
    Abstract: There is provided a mobile positioning apparatus for performing map matching based on a pixel image. The mobile positioning apparatus comprises a position storage indicating a current position of a mobile body and likelihood information thereof as a nonparametric distribution; a movement vector estimation device which outputs a movement vector indicating a moving distance and a moving direction of the mobile body at a discrete time T and likelihood information thereof; an image database which holds a peripheral map of a range of movement of the mobile body as an image group of a resolution according to a moving resolution of the mobile body; and a pixel crossing determination device which performs map matching using the position information group and a the movement vector based on the peripheral map.

  • Patent number: 7222045
    Abstract: A posture angle processing apparatus includes a magnetic sensor, a gravitational acceleration sensor, a position information acquisition device, and a dip angle database device wherein a correlation of the absolute location and a geomagnetic dip angle at the corresponding point is stored. Based on the absolute location of the current point, a dip angle estimation and determination device reads the geomagnetic dip angle at the current point, calculates an angle formed by a horizontal plane and the magnetic vector, compares the angle formed by the magnetic vector and the horizontal plane with the geomagnetic dip angle of the current point, and outputs either a true signal or a false signal depending on the error between the angle and the geomagnetic dip angle.
