  • Publication number: 20220329742
    Abstract: A photographing apparatus for photogrammetry continuously photographs a target object performing a series of motions by synchronizing a plurality of photographing devices provided at a plurality of different viewpoints. The plurality of photographing devices include the plurality of image-capturing units that photograph the target object. Each of the plurality of photographing devices includes the plurality of primary storages each storing each image data of the target object photographed in synchronization by the plurality of image-capturing units, and the plurality of signal output units each outputting a completion signal for each of the image data when storage of each of the image data in a preceding motion of the target object into the plurality of primary storages is completed. The plurality of photographing devices perform photographing in the subsequent motion of the target object based on the completion signal of the signal output unit.

  • Patent number: 11371462
    Abstract: The control apparatus for a compression ignition type engine includes a plurality of cylinder inner pressure sensors that detect pressure in each cylinder, and a combustion control unit. The combustion control unit corrects a target fuel injection amount of each cylinder by an injector based on a deviation between a predicted combustion period that is a period from an ignition timing by an ignition plug to a predetermined mass combustion timing and that is obtained based on a preset combustion model, and an actual combustion period that is a period from the ignition timing by the ignition plug to an actual combustion timing and that is obtained based on cylinder inner pressure, such that the period from the ignition timing by the ignition plug to the predetermined mass combustion timing, which is the timing when fuel having a predetermined mass ratio combusts, is equalized in each cylinder.
