Abstract: The disclosure discloses a magnetic stimulation method with a controllable induced field direction, and belongs to the technical field of noninvasive neural regulation. The method includes the following steps: S100, calculating currents i1j, i2j, i3j, j=1, 2, . . . n required to be made to generate a unit-direction vector electric field at a target point Pt, the same below; S200, decomposing a vector electric field E required at the target point to three fundamental vector directions to obtain electric field components E1, E2, E3; S300, calculating currents that may generate the electric field components E1, E2, E3 at the target point, I1j=E1i1j, I2j=E2i2j, I3j=E3i3j; S400, superimposing the currents of the three energization modes to obtain a resultant current Ij=I1j+I2j+I3j=E1i1j+E2i2j+E3i3j to be made of each coil of a coil group, that is, generating a required electric field E at the target point for specific directional simulation.

Abstract: A system and method for determining a dimension of a target. The method includes: determining a camera parameter, the camera parameter including at least one of a focal length, a yaw angle, a roll angle, a pitch angle, or a height of one or more cameras; acquiring a first image and a second image of an target captured by the one or more cameras; generating a first corrected image and a second corrected image by correcting the first image and the second image; determining a parallax between a pixel in the first corrected image and a corresponding pixel in the second corrected image; determining an outline of the target; and determining a dimension of the target based at least in part on the camera parameter, the parallax, and the outline of the target.
