Contour line surveying and mapping auxiliary device

Abstract

The invention relates to a contour line surveying and mapping auxiliary device. The contour line surveying and mapping auxiliary device comprises a camera device, wherein a glass lens is arranged in the front of the camera device; a shooting imaging area is arranged behind the glass lens; the shooting imaging area is fixed in the camera device through a clamping plate; the front part of the glasslens is also provided with a heating wire; a mini fan is arranged at the inclined lower part of the heating wire; the glass lens is fixed in the camera device through fixing rings; a ventilation plateis arranged behind the shooting imaging area; a control unit and a power source are arranged on the ventilation plate; evenly distributed through holes are formed in the ventilation plate; a humiditysensor is arranged between the ventilation plate and the clamping plate; a heating pipe is arranged on the rear portion of the ventilation plate; and a connecting part is further arranged at the tailend of the outer portion of the camera device. The contour line surveying and mapping auxiliary device has the advantages of being convenient to use, high in safety performance and easy to operate.

Description

technical field [0001] The invention relates to the technical field of map surveying and mapping, in particular to an auxiliary device for contour line surveying and mapping. Background technique [0002] In the surveying and mapping work of contour lines, the data collection of topographical feature points is particularly important. The existing measurement methods mainly use UAV aerial surveys for data collection. UAV aerial surveys are flexible, efficient, fast, precise and accurate. Low cost, wide application range, short production cycle and other characteristics, it has obvious advantages in the rapid acquisition of high-resolution images in small areas and difficult-to-fly areas. However, in the surveying and mapping of contour lines, drones mainly work in mountainous areas, The environment in the environment is often relatively humid, and the temperature difference between day and night is large, so the unmanned aerial vehicle often has the phenomenon of unclear came...

[0002] In the surveying and mapping work of contour lines, the data collection of topographical feature points is particularly important. The existing measurement methods mainly use UAV aerial surveys for data collection. UAV aerial surveys are flexible, efficient, fast, precise and accurate. Low cost, wide application range, short production cycle and other characteristics, it has obvious advantages in the rapid acquisition of high-resolution images in small areas and difficult-to-fly areas. However, in the surveying and mapping of contour lines, drones mainly work in mountainous areas, The environment in the environment is often relatively humid, and the temperature difference between day and night is large, so the unmanned aerial vehicle often has the phenomenon of unclear camera during the work project. This is because the camera device is prone to liquefaction in humid areas. Water mist will cause insufficient clarity of the camera, which will lead to deviations in the recorded data. Since humid air can easily enter the camera, it will easily cause corrosion of internal components and shorten the service life of the camera device; It is very necessary to have a contour mapping auxiliary device with clear shooting and dry effect
