A method for planning sample points for surveying and mapping, comprising obtaining a combined photographing area corresponding to a combined photographing point set, wherein the combined photographing point set comprises: a central photographing point and four peripheral photographing points, and the four peripheral photographing points are four vertices of a rectangle centered on the central photographing point; the combined photographing area is an area synthesized by photos taken at the central photographing point and the four peripheral photographing points; a relative position relationship between the central photographing point and the four peripheral photographing points meets a condition as follows: a composite photo to be obtained by photographing based on the central photographing point and the four peripheral photographing points is of a rectangular shape; each photo to be obtained based on each of the four peripheral photographing points and a photo to be obtained based on the central photographing point meet a preset photo overlap degree index, the preset photo overlap degree index is configured to characterize an overlap degree between the photo to be obtained based on each of the four peripheral photographing points and the photo to be obtained based on the central photographing point; and an overlap degree between photos to be obtained based on each two peripheral photographing points is less than the preset photo overlap degree index; determining, within an area to be surveyed and mapped, a plurality of combined photographing areas for surveying and mapping according to a shape and size of the combined photographing area corresponding to the combined photographing point set and a shape and size of the area to be surveyed and mapped, wherein the plurality of combined photographing areas for surveying and mapping are photographing areas that are independent from each other and formed by dividing the area to be surveyed and mapped according to the shape and size of the combined photographing area and the shape and size of the area to be surveyed and mapped, and a shape and size of each of the plurality of photographing areas is the same as a shape and size of the combined photographing area; determining, in each of the plurality of combined photographing areas for surveying and mapping, a plurality of photographing location points according to the relative position relationship between the central photographing point and the four peripheral photographing points, comprising: mapping the central photographing point in the combined photographing point set to an area midpoint with geographic position information and in the combined photographing area for surveying and mapping, and determining the area midpoint as a photographing location point; and mapping respectively the four peripheral photographing points to four photographing location points with geographic position information and in the combined photographing area for surveying and mapping according to the relative position relationship between the central photographing point and the four peripheral photographing points; and determining the plurality of photographing location points as the sample points for surveying and mapping by an aircraft for surveying and mapping. determining, within an area to be surveyed and mapped, a plurality of combined photographing areas for surveying and mapping according to a shape and size of the combined photographing area corresponding to the combined photographing point set and a shape and size of the area to be surveyed and mapped, wherein the plurality of combined photographing areas for surveying and mapping are photographing areas that are independent from each other and formed by dividing the area to be surveyed and mapped according to the shape and size of the combined photographing area and the shape and size of the area to be surveyed and mapped, and a shape and size of each of the plurality of photographing areas is the same as a shape and size of the combined photographing area; determining, in each of the plurality of combined photographing areas for surveying and mapping, a plurality of photographing location points according to the relative position relationship between the central photographing point and the four peripheral photographing points, comprising: mapping the central photographing point in the combined photographing point set to an area midpoint with geographic position information and in the combined photographing area for surveying and mapping, and determining the area midpoint as a photographing location point; and mapping respectively the four peripheral photographing points to four photographing location points with geographic position information and in the combined photographing area for surveying and mapping according to the relative position relationship between the central photographing point and the four peripheral photographing points; and determining the plurality of photographing location points as the sample points for surveying and mapping by an aircraft for surveying and mapping.
