  • Publication number: 20240104879
    Abstract: In various examples, calibration techniques for interior depth sensors and image sensors for in-cabin monitoring systems and applications are provided. An intermediary coordinate system may be generated using calibration targets distributed within an interior space to reference 3D positions of features detected by both depth-perception and optical image sensors. Rotation-translation transforms may be determined to compute a first transform (H1) between the depth-perception sensor's 3D coordinate system and the 3D intermediary coordinate system, and a second transform (H2) between the optical image sensor's 2D coordinate system and the intermediary coordinate system. A third transform (H3) between the depth-perception sensor's 3D coordinate system and the optical image sensor's 2D coordinate system can be computed as a function of H1 and H2. The calibration targets may comprise a structural substrate that includes one or more fiducial point markers and one or more motion targets.

  • Patent number: 11574759
    Abstract: The present invention discloses a device for evaluating and demagnetizing residual magnetism quantity of a power transformer. A main circuit comprises a switching power supply the two ends of which are respectively connected with a filter capacitor and a resistor in parallel. A forward end of the switching power supply is connected with a main switch in series. A rear end of the main switch is connected with a series branch of a sixth switch and a first resistor, a series branch of a first switch and a second switch, and a series branch of a third switch and a fourth switch are connected in parallel. A driving circuit is respectively connected with driving ends of the main switch, the sixth, first, second, third and fourth switches. A control circuit is connected with the driving circuit for sending an instruction to the driving circuit.
