Surveying and mapping instrument, surveying and mapping method and device, terminal device and storage medium

Abstract

The invention is applicable to the field of surface surveying and mapping, and provides a surveying and mapping instrument, a surveying and mapping method and device, a terminal device and a storage medium, wherein the surveying and mapping instrument comprises a camera; and a composite frame on which the camera is installed and which comprises a machine body, an inner machine body frame and an outer machine body frame, wherein the inner machine body frame is used for driving the camera to rotate in a pitching direction, and the outer machine body frame is used for driving the camera to rotatein a transverse rolling direction so as to achieve the two-dimensional scanning imaging of the ground surface. The surveying and mapping instrument can provide a working mode based on two-dimensionalscanning, so that the large-base-height-ratio inclined wide-width imaging in a single flight strip can be achieved, namely, the large-inclination, wide-width, efficient and high-precision surveying and mapping in the single flight strip are achieved by combining the flight direction revisit and the large-angle whisk-broom imaging in the direction perpendicular to the flight direction, and accordingly the aerial surveying and mapping efficiency and precision are both improved.

Description

technical field [0001] The invention belongs to the field of surface surveying and mapping, and in particular relates to a surveying and mapping instrument, a surveying and mapping method and device, terminal equipment, and a storage medium. Background technique [0002] In order to realize high-altitude long-distance large-scale high-precision surveying and mapping, a surveying and mapping camera with a long focal length is required. At present, the focal length of existing surveying and mapping cameras at home and abroad is relatively short, generally no more than 200mm, which not only cannot meet the needs of high-altitude and long-distance high-precision surveying and mapping, but also has low efficiency and accuracy. It needs to work vertically and overhead, and cannot be applied to tilt surveying and mapping. [0003] Therefore, it is necessary to improve the existing aerial surveying and mapping technology in order to improve the efficiency and accuracy of aerial sur...
