  • Publication number: 20160279809
    Abstract: An information processing apparatus having a changed region detection unit performs a process that includes repeating a cycle. The cycle includes causing a projection unit to project a pattern, that includes light and dark portions, onto target objects, causing an image capturing unit to capture an image of the target objects while the pattern is being projected by the projection unit, and causing a holding unit to hold one of the target objects based on a captured image obtained by the image capturing processing. Based on a reference boundary position corresponding to a boundary between the light and dark portions in the pattern in the captured image obtained in a previous cycle and a target boundary position in the captured image obtained in a current cycle, the changed region detection unit detects a changed region with a change between the previous cycle and the current cycle.

  • Publication number: 20150269789
    Abstract: Operation of self-propelled mining equipment in the field can be accurately recognized at a remote position of the equipment. A management center for controlling a dump truck receives signal from sensors in order to show detection data for the working status of the operation instruments and warning indication data based upon the detection data. The warning indication data and the detection data for the working status of the operation instruments are displayed on the same display. Alternatively, in place of the detection data for working status of the operation instruments, related information from a data base concerning the record of maintenance previously conducted may be displayed, or a graph of the detection data for the working status of an operation instrument of another dump truck which is operating in the same working field may be displayed.

  • Publication number: 20140351148
    Abstract: A maintenance information coordination system coordinates maintenance-related information held by a user of a machine or held by an independent maintenance service provider company of the machine. Maintenance-related information is held by a provider of the machine. A user machine inference unit of the maintenance information coordination system infers a machine identifier provided by the provider of the machine, which operates in a zone for which maintenance work information has been recorded from a provider machine information storage unit, a user information storage unit and an operation information storage unit. It further infers a mapping relation between the machine identifier assigned by the provider and an identifier of the machine assigned by its user from operation information of the machine and information in a user machine information storage unit, and a maintenance work information storage unit and stores the mapping relation into an integrated maintenance information storage unit.
