  • Patent number: 10977825
    Abstract: [Problem] To enable three-dimensional measurement with good precision. [Solution] When three-dimensional measurement is to be performed with good precision using SLAM or the like, images of marks M1, M2, M3, M4 must be captured from various directions by a single-lens camera. In the present invention, directions of imaging by a camera are displayed as sectors C1, C2, C3, C4. For example, it is understood that whereas sectors C1 and C4 have a large central angle and imaging therein is performed from a wide range of directions, sectors C2 and C3 have a small central angle and imaging therein is performed from a narrow range of directions. A photographer seeing such a display can perform additional imaging, and images can therefore be obtained from a wide range of directions, and three-dimensional measurement can be performed with good precision.

  • Patent number: 10954701
    Abstract: A motor vehicle door lock device comprises a locking mechanism, a locking motor, an electric release mechanism, an opening lever, and an outside handle. An ECU includes an authenticating portion. When the authenticating portion authenticates a signal from a transmitter and the locking mechanism starts switching from a locking state to an unlocking state by the locking motor, ECU controls a releasing motor so that the electric release mechanism is actuated because a switch detects door-opening action of the outside handle. The locking mechanism is switched to the unlocking state without contacting the opening lever from a direction where the opening lever cannot be actuated. A locked door can be opened with the outside handle at a single action and prevents a panic.
