Abstract: The embodiments of the disclosure provide a method, apparatus, and electronic device for hand three-dimensional reconstruction. One specific implementation of the method includes: obtaining hand images acquired at at least two angles of view; determining an initial hand three-dimensional reconstruction result corresponding to each of the hand images based on a predetermined hand three-dimensional reconstruction network, wherein the hand three-dimensional reconstruction result comprises a hand three-dimensional model and a hand key point; and fusing the initial hand three-dimensional reconstruction results corresponding to the hand images acquired at the at least two angles of view to obtain a fused hand three-dimensional reconstruction result. With consistency of a plurality of angles of views, the implementation may make the fused hand three-dimensional reconstruction result more accurate.

Abstract: A method may include identifying a time window of a procedure. The method may also include obtaining operational information of the time window. The operational information may include a limit of pulse repetition frequency (PRF) acceleration and a plurality of preliminary radio frequency (RF) PRFs. The method may also include determining a plurality of updated RF PRFs by updating the plurality of preliminary RF PRFs. A rate of variation between any two adjacent updated RF PRFs may be less than or equal to the limit of PRF acceleration. The method may also include causing an RF source to generate electromagnetic waves at the plurality of updated RF PRFs in the time window.
