Embodiment Construction
[0031] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
[0032] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.
[0033] The first embodiment of the present invention provides a surveying and mapping instrument, which is mounted on a flying object for ground surface surveying and mapping. Such as Figure 1-3 As shown, the surveying instrument may include a camera 1 and a composit...

The present invention is applicable to the field of surface surveying and mapping, and provides surveying and mapping instruments, surveying and mapping methods and devices, terminal equipment, and storage media, wherein the surveying and mapping instruments include: a camera; a composite frame, the camera is installed on the composite frame, and the composite The frame includes a fuselage, an inner frame of the fuselage and an outer frame of the fuselage, the inner frame of the fuselage is used to drive the camera to rotate in the pitch direction, and the outer frame of the fuselage is used to drive the camera to rotate in the roll direction Rotate to realize two-dimensional scanning and imaging of the earth's surface. Among them, the surveying and mapping instrument can provide a working method based on two-dimensional scanning, so as to realize oblique wide-width imaging with a large base-height ratio in a single flight zone, that is, the combination of revisiting according to the flight direction and large-angle swing-sweep imaging in the vertical flight direction to achieve single Large inclination, wide width, high efficiency and high precision surveying and mapping within the flight zone, thus improving the efficiency and accuracy of aerial surveying and mapping.
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...
