Description

Technical Field

[0001] The utility model relates to the technical field of remote sensing mapping, in particular to an engineering surveying and mapping device based on the remote sensing mapping technology. Background Art

[0002] Remote sensing technology is a comprehensive technology that is based on the theory of electromagnetic waves and uses various sensing instruments to collect, process and finally image the electromagnetic wave information radiated and reflected by distant targets, thereby detecting and identifying various ground scenes. Remote sensing technology has been widely used in many aspects of the national economy and military, such as meteorological observation, map surveying and mapping, military reconnaissance, etc.

[0003] When conducting remote sensing mapping, since it is inconvenient to survey large mountainous sites, in order to improve the efficiency of surveying and mapping, people often use drones equipped with remote sensing mapping instruments to complete remote sensing mapping of large mountainous sites, thereby improving the efficiency of surveying and mapping.

[0004] In the prior art, when a UAV equipped with a remote sensing mapping instrument is launched to perform remote sensing mapping of a mountain site, the quality of 3D modeling will be seriously affected due to overexposure or underexposure of the image, ghosting, defocusing and noise of the image. In order to avoid such exposure problems, cloudy weather is often chosen for aerial photography. However, in cloudy weather, after the UAV is launched, the humidity in the air at high altitudes in the mountainous area will increase with the increase in altitude. When the fan in the remote sensing mapping instrument supplies air to the interior to dissipate heat for the internal electrical components, it is easy to cause moisture to enter the interior, thereby causing the remote sensing mapping instrument to become damp, increasing the difficulty of maintenance. If maintenance is not performed in time, the service life of the equipment will be reduced or even damage will be caused. At the same time, the lens is prone to fogging at high altitudes, thereby reducing the accuracy of mapping. Therefore, an engineering surveying and mapping device based on remote sensing mapping technology is proposed. Utility Model Content
