Zusammenfassung:The invention relates to a ground point elevation determination method, device and equipment and a computer program product. In at least one embodiment of the invention, after the ground point in the point cloud is obtained, the target point for fitting the ground plane is screened out by using the elevation of the point in the local area where the ground point is located, so that local noise points are filtered out for the ground point, full noise point filtering is not needed, and the efficiency is improved; furthermore, the ground plane obtained by using target point fitting is more accurate; therefore, the elevation of the ground point is updated by utilizing the elevation of the projection point of the ground point on the fitted ground plane, so that the elevation of the ground point is more accurate, and the precision of the high-precision map is improved. 本公开涉及一种地面点高程确定方法、装置、设备及计算机程序产品。本公开的至少一个实施例中,在获取点云中的地面点后,利用地面点所在局部区域内的点的高程,筛选出用于拟合地面平面的目标点,实现针对地面点,滤除局部噪声点,无需进行全量噪声点滤除,提高效率;进而,利用目标点拟合得到的地面平面更加精确;从而,利
