Problems solved by technology

[0004] 1. Most of the measuring devices can carry out multi-angle photogrammetry in the horizontal direction, but not oblique photogrammetry. At the same time, the overall height of the device is inconvenient to adjust and the accuracy of angle modification is low;
[0005] 2. The position of the photogrammetry end is relatively fixed and it is difficult to adjust the measurement range of a single photogrammetry end, and the angle adjustment of the photogrammetry end cannot be adjusted in the vertical direction

Embodiment Construction

[0030] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but the present invention can be implemented in many different ways that are predetermined and covered by the claims.

[0031] Such as Figure 1 to Figure 6 As shown, a quick modification device based on oblique photogrammetry includes a major mechanism 1 and a minor mechanism 2. The major mechanism 1 is set on the existing ground, and the upper end of the major mechanism 1 is provided with a minor mechanism 2.

[0032]The main repair mechanism 1 includes a seat plate 10, a bottom block 11, a hollow rod 12, a level 13, a built-in rod 14, a buckle 15, a No. 1 bolt 16, a No. 1 ear plate pair 17, a support plate 18 and an insertion rod 19. A bottom block 11 is installed on the middle part of the upper end surface of the seat plate 10, and the upper middle part of the bottom block 11 is rotatably connected with the lower end of the hollow rod 12. The fro...

Abstract

The invention relates to a rapid modification device based on oblique photogrammetry, wherein the device comprises a main repair mechanism and an auxiliary repair mechanism; the main repair mechanism is arranged on the existing ground, and the auxiliary repair mechanism is arranged at the upper end of the main repair mechanism. The design concept of multi-control is adopted for rapid modification of oblique photogrammetry, the main repair mechanism not only can realize photogrammetry at different heights, but also can realize photogrammetry within a certain inclination angle range as a whole, the inclination angle of the main repair mechanism is fast and accurate to return and adjust, and the auxiliary repair mechanism can meet the requirement of photogrammetry of a single camera main piece at a certain inclination angle. Therefore, multi-angle photogrammetry in different directions can be realized, and meanwhile, correction and return of the rotation angle of a camera shooting main part can be quickly and accurately carried out.

Description

technical field [0001] The invention relates to the field of photogrammetry instruments, in particular to a quick modification device based on tilt photogrammetry. Background technique [0002] Photography refers to the process of using some special equipment for image recording. Generally, we use mechanical cameras or digital cameras for photography. Sometimes photography is also called photography, which is the process of exposing the photosensitive medium through the light emitted or reflected by the object. , photogrammetry refers to the technology of measuring the shape, size and spatial position of the target object by using the combination of camera and film. [0003] The main task of photogrammetry is to measure topographic maps of various scales, establish topographic databases, provide basic spatial data for various geographic information systems, land information systems and various projects, and serve non-topographic fields, such as industrial In the fields of c...
