Palm contour extraction method and apparatus, and control instruction generation method and apparatus

A computer device, comprising a memory and one or more processors, the memory having computer-readable instructions stored therein, and the computer-readable instructions, when executed by the one or more processors, causing the computer device to perform a palm contour extraction method including:

• obtaining bone point positions and bone point types of palm bone points in a target palm image;
• dividing the palm bone points into a plurality of palm bone point sets based on their corresponding bone point positions and the bone point types, each palm bone point set having a corresponding geometry processing type;
• generating a plurality of palm contour auxiliary lines respectively corresponding to the plurality of palm bone point sets based on the bone point positions of the plurality of palm bone point sets, each palm contour auxiliary line matching a geometry processing type of a corresponding palm bone point set;
• determining a plurality of palm contour points from the plurality of palm contour auxiliary lines based on their respective geometry processing types;
• and
• generating a palm contour corresponding to the target palm image based on the plurality of palm contour points.
