High-stability photographing device for geographic mapping

Abstract

The invention relates to the technical field of geographic mapping, and discloses a high-stability photographing device for geographic mapping. The photographing device comprises a main rod; and the top of the main rod is fixedly connected with a top frame. Through the combined action of the top frame, a clamping block, a movable rod, a rotating column and a rotating disc, a camera is controlled to be in a fixed state by rotating a rotating button, so that the situation that the camera deviates or even falls off due to improper use is avoided, the stability of the camera is improved, the geographic mapping operation is facilitated, the operation is convenient, and the camera is convenient to take. Through the combined action of a pressing ring, an arc rod, a frame rod, an eccentric disc, asleeve, a branch pipe and a support rod, diffusivity is automatically performed to carry out triangular supporting so as to improve the stability of a support; the support length is automatically adjusted according to the flatness degree of the ground, so that the camera is kept in a horizontal state, and the photographing operation is facilitated; and compared with a traditional support mode, the operation is more convenient, and the automation degree is higher.

Description

technical field [0001] The invention relates to the technical field of geographic surveying and mapping, in particular to a highly stable photographic device for geographic surveying and mapping. Background technique [0002] Geographic surveying and mapping is based on natural geographical elements or the surface, and measures, collects and draws the shape, size, spatial position and attributes of artificial facilities, etc., and usually operates in areas that are about to be developed or undergo large-scale engineering construction. Surveying and mapping engineers measure and draw topographic maps, which is conducive to decision-making, planning and design. Before the measurement, the bracket needs to be erected stably, the camera is fixed on the bracket, and the camera is stable and placed horizontally. However, in the actual operation process, it is not easy to fix the camera, and the operation is cumbersome, and because the surveying and mapping operations are generall...

AI Technical Summary

Problems solved by technology

However, in the actual operation process, it is not easy to fix the camera, and the operation is cumbersome, and because the surveying and mapping operations are generally carried out in the field, the environment is difficult, and the ground is usually uneven, requiring the staff to constantly adjust the position of the bracket with the naked eye , try to keep it stable and its placement platform is in a horizontal state, which has a large error, and the operation is cumbersome, which is not conducive to the surveying and mapping operation
