Map point data extraction method and device, storage medium and equipment

The embodiment of the invention discloses a map point data extraction method and device, a storage medium and equipment, and the method specifically comprises the steps: firstly obtaining a to-be-processed map point data set which comprises M pieces of map point data, and determining a distribution region corresponding to the set according to the M pieces of map point data; and dividing the distribution area into n sub-areas by using an equal division area method, and obtaining the number of map point data included in each sub-area;, determining the number m of the sub-regions with the non-zero number of the map point data, judging whether the m meets a preset condition or not; if not, updating the n by utilizing the target parameter, and dividing the distribution region again until the mmeets the preset condition; when m meets a preset condition, determining one piece of map point data from each of the m sub-regions to obtain m pieces of map point data; and sorting the m pieces of map point data according to
