Provided are a positive electrode material coated with a mixed solid-state electrolyte and a preparation method thereof, a positive electrode plate, a solid-state battery, and an electrical-related device. The positive electrode material coated with the mixed solid-state electrolyte includes a positive electrode material and a mixed solid-state electrolyte coating the surface of the positive electrode material, and the mixed solid-state electrolyte includes an oxide solid-state electrolyte, a sulfide solid-state electrolyte, and a halide solid-state electrolyte. By designing the positive electrode material coated with the mixed solid-state electrolyte, the oxide solid-state electrolyte provides mechanical properties, the sulfide solid-state electrolyte provides ionic conductivity, and the halide solid-state electrolyte provides a stable interface. The combination of the three solid-state electrolytes can effectively improve the structural stability and conductivity of the positive electrode material, thereby improving the cycle stability of the battery.

The present invention provides a gesture tracking method and apparatus, a computer device, and a readable storage medium. The gesture tracking method includes: acquiring a vehicle cabin video data stream, and capturing images from the vehicle cabin video data stream to obtain a plurality of image frames; triggering hand detection on image frames at preset time intervals to obtain hand position information for each triggered image frame; determining, for each triggered image frame, hand position information for each non-triggered image frame based on the hand position information for the triggered image frame; matching the hand position information for each hand based on the hand position information for every two consecutive image frames to obtain a matching result of the hand position information for each hand; and determining a dynamic gesture in the vehicle cabin video data stream based on the matching result of the hand position information for each hand in every two consecutive image frames. This method reduces the computational power required for gesture tracking, thereby lowering the requirements for device computing capability, minimizing limitations, and ensuring normal gesture tracking through various devices.

The present disclosure provides a method, an apparatus, an electronic device, and a storage medium for determining camera extrinsic parameters within a vehicle. In the present disclosure, the camera extrinsic parameters are obtained through interior points, which can avoid the use of a calibration board and obtain the camera extrinsic parameters without manual intervention, which helps reduce operational requirements when determining the camera extrinsic parameters.
