Claim 11:
12. The apparatus of claim 11, wherein the instructions further cause the processor to be configured to:
determine that the (i+1)th pre-grouped subgroup is one of the subgroups when a first difference between a third quantity of frames of point clouds comprised in the re-obtained (i+1)th pre-grouped subgroup and a fourth quantity of frames of point clouds comprised in the (i+1)th pre-grouped subgroup obtained for the first time is less than or equal to a second preset quantity;
obtain an (i+2)th pre-grouped subgroup using a fourth step size when the first difference is greater than the second preset quantity, wherein a sum of the second step size and the fourth step size is less than the first step size;
obtain an (i+3)th pre-grouped subgroup using a fifth step size when fifth feature information of the (i+2)th pre-grouped subgroup meets the preset condition, wherein a sum of the second step size, the fourth step size, and the fifth step size is less than the first step size; and
determine that an (i+k)th pre-grouped subgroup is one of the subgroups when a second difference between a fifth quantity of frames of point clouds comprised in an obtained (i+k)th pre-grouped subgroup and the fourth quantity of frames of point clouds is less than or equal to the second preset quantity and when sixth feature information of the (i+k)th pre-grouped subgroup meets the preset condition, wherein k is an integer greater than or equal to 2.
