Claim 10:
11. The apparatus of claim 1, wherein the instructions further cause the processor to be configured to:
slide, using the jth frame of the point cloud as the start point, a window for the ith time on the second point clouds to obtain the ith pre-grouped subgroup;
obtain an (i+1)th pre-grouped subgroup using a first step size for a first time;
re-obtain the (i+1)th pre-grouped subgroup using a second step size when the second feature information meets a preset condition and when third feature information of the (i+1)th pre-grouped subgroup does not meet the preset condition, wherein the second step size is less than the first step size;
re-obtain the (i+1)th pre-grouped subgroup using a third step size when fourth feature information of a re-obtained (i+1)th pre-grouped subgroup does not meet the preset condition, wherein the third step size is less than the second step size; and
determine that the ith pre-grouped subgroup is one of the subgroups when a quantity of times of re-obtaining the (i+1)th pre-grouped subgroup reaches a preset quantity of times or a latest step size of a latest re-obtained (i+1)th pre-grouped subgroup is less than or equal to a preset step size, and when latest feature information of the latest re-obtained (i+1)th pre-grouped subgroup does not meet the preset condition.
