Low altitude photography image control point arranging method

The invention relates to the technical field of electrical power engineering survey, belongs to the field of surveying and mapping and particularly relates to a low altitude photography image control point arranging method. According to an aerial photographic regional map, a mark distribution model is established and control mark points are arranged in an aerial photographic regional network; plane control points are arranged around an aerial photographic region; the length of a photographic baseline is b; in the process of encrypting point positions under high precision, the span of the heading spacing is in the range of 6 to 8b and the span of the lateral spacing is 4b; a pair of image control points are respectively arranged at both ends of each route; vertical control points are arranged into a lock shape; the spans of the vertical control points along the lateral spacing are 4b and the spans of the vertical control points along the heading spacing is 6 to 8b; and when plane point positions are encrypted
