Photography auxiliary tool for digital building surveying and mapping

Abstract

The invention discloses a photography auxiliary tool for digital building surveying and mapping. The photography auxiliary tool comprises a base, a groove is formed in the base, a first lead screw isarranged in the groove, and the right end of the first lead screw is rotationally connected with a power output shaft of a first motor through a coupler; and the first lead screw is provided with a threaded base in rotary fit with the first lead screw, a first connection base is fixedly connected to the threaded base, a connection rod is hinged to the first connection base, a second connection base is hinged to the other end of the connection rod and fixed to the bottom face of a tank, a rotary table is arranged on the tank, and a photography rack is arranged on the rotary table. The tool is convenient to use, accurate positioning can be achieved through control by the device, digital surveying and mapping on a building are completed by shooting the building through a photography device, the surveying and mapping work is completed, resources are saved, and the building surveying and mapping cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of photographic auxiliary tools for digital architectural surveying and mapping, in particular to a photographic auxiliary tool for digital architectural surveying and mapping. Background technique [0002] At present, the well-known architectural surveying and mapping method is the "traditional architectural surveying and mapping method", and its application range includes ancient architectural surveying and mapping, as well as modern and modern architectural surveying and mapping. "Traditional architectural surveying and mapping method" refers to the architectural surveying and mapping method in the modern sense created by the first generation of Chinese architects, Liang Sicheng and Liu Dunzhen, after Zhu Qiqian founded the "China Construction Society" in 1930. Later, it was widely used in China's architectural surveying and mapping industry and has continued to this day. [0003] One of the disadvantage...

Problems solved by technology

[0003] One of the disadvantages of the traditional architectural surveying and mapping method is that tall buildings need to build scaffolding for surveying and mapping. If scaffolding is not built, the building facade surveying and mapping of the parts of the building that the surveyor cannot directly contact will not be able to survey and map.

It takes a lot of financial and material resources to build scaffolding, which greatly increases the cost of building surveying and mapping; if the tall buildings that need to be surveyed and mapped do not have the conditions to build scaffolding, the surveying and mapping of building facade surveying and mapping will not be possible, and the degree of intelligence of the measuring instruments It is not high, which will affect the measurement accuracy. Therefore, we propose a photographic auxiliary tool for digital architectural surveying and mapping
