About merging multi-frame lidar cloud at the same location

[Icecream-blue-sky]

When multi-frame point clouds are fused, there may be multiple point clouds in the same location, and np.configure will keep all the point clouds in the same location instead of just one.

################## concatenate all static scene segments  ########################
    lidar_pc_list = [dict['lidar_pc'] for dict in dict_list]
    lidar_pc = np.concatenate(lidar_pc_list, axis=1).T

Does this matter?
