  Application of visible light remote sensing by UAV in forest resource parameter extraction

  With the development and maturity of UAV low altitude aerial photogrammetry technology,the traditional methods and means of forest resources survey have been improved.UAV remote sensing technology has accelerated the digitization and intelligence of forest resources survey.Today,micro UAV constitutes UAV low altitude remote sensing system by carrying a variety of sensors,which can be flexibly deployed under complex conditions and perform a variety of remote sensing tasks.UAV remote sensing has the advantages of low cost,low risk and strong adaptability.It can be used as a powerful supplement to satellite remote sensing and manned aerial remote sensing.The traditional manual field investigation can only be conducted once in the sample plot,and the results can not be traced and documented.The accuracy of the results depends on the subjective behavior of the investigators,and the results can not be effectively verified.In contrast,the survey method based on UAV remote sensing can locally archive and conduct any number of surveys at any time after obtaining the survey area data,and the objectivity,accuracy and efficiency of the survey can be well guaranteed.Existing academic research shows that UAV equipped with high-resolution digital camera can accurately extract many stand factors,including forest area,tree species composition,stand number,stand canopy density and stand height.The development of UAV remote sensing technology provides the possibility to achieve the goal of information extraction of key indicators of afforestation achievements.

Application of UAV equipped with multispectral sensors in forestry resources investigation and water quality monitoring

  Compared with ordinary visible RGB three channel camera,multispectral sensor can obtain more channel and band information.Therefore,for the subject,it can show the information in different spectral bands and show more fine spectral characteristics.

  The main application directions of multispectral sensors are:

  ◆Forestry:forestry fire prevention,forestry diseases and insect pests,tree species analysis,vegetation growth;

  ◆Agriculture:crop growth assessment,agricultural pest control,commercial crop monitoring,water and soil conservation;

  ◆Water conservancy:water pollution,rich oxidation,cyanobacteria monitoring,total phosphorus and total nitrogen inversion,etc

  ◆Electric power:fast growing vegetation identification and extraction;

  ◆Environmental protection:spectral analysis of air pollution,river pollution monitoring,eutrophication monitoring of lakes and reservoirs,marine red tide and lake cyanobacteria monitoring;

  ◆Police use:Supervision of drug(opium poppy)cultivation,monitoring of drug manufacturing and environmental pollution

  ◆Military:camouflage interpretation,minefield mine location extraction.

Application of UAV oblique Photogrammetry in large-scale topographic mapping

  Oblique photogrammetry technology is a high-tech developed in the field of international surveying and mapping in recent years.It overturns the limitation that orthophoto images can only be taken from a vertical angle in the past.By carrying multiple sensors on the same flight platform and collecting images from five different angles,such as one vertical and four tilts,it introduces users into a real and intuitive world in line with human vision.Large scale topographic mapping is a mature application of UAV oblique photogrammetry technology.The main steps include field data acquisition and data processing.

  Application of UAV equipped with thermal infrared sensor in forest fire prevention

  UAV equipped with infrared thermal imaging monitoring system,combined with modern network transmission technology,can realize real-time monitoring and remote transmission of information,break the restrictions of environment,region and distance,truly realize the synchronous sharing of remote real-time information resources and late software intelligent identification and analysis,and achieve the purpose of efficiently ensuring people's life and property safety.The advantages of infrared thermal imaging monitoring technology based on UAV are also reflected in the following aspects:

  Firstly,the imaging principle of the infrared thermal imager is based on the temperature difference.As long as the measured object has a temperature difference of 0.06-0.08 centigrade,the infrared thermal imaging monitoring system can distinguish it and image it for visual display.This characteristic just meets the needs of forest fire prevention monitoring to observe the subtle temperature changes over the forest area.

  Secondly,the use of infrared thermal imaging monitoring system can truly realize all-weather monitoring,especially at night,and its observation effect is the same or even better than that in the day.

  Thirdly,compared with the traditional photography and imaging at a fixed place,the thermal imaging carried on the mobile carrier UAV can conduct fire inspection over the whole forest,so as to find the fire hazards in time,give the location of the hazards in time,and notify the relevant personnel to deal with them in time.

  Finally,in foggy weather,the infrared thermal imaging monitoring system can penetrate the dense fog and image clearly.This advantage is far more prominent than the ordinary CCD monitoring,especially suitable for the monitoring of key fire prevention areas in mountains and forests.

  Application of UAV airborne LiDAR in topographic mapping

  The laser pulse emitted by the airborne LiDAR sensor mounted on UAV can penetrate part of the forest shelter and directly obtain high-precision 3D surface terrain data.While acquiring the laser point cloud,the clear ground image is synchronously obtained through the high spatial resolution camera.Then the laser point cloud data and image data are jointly processed to obtain high-precision orthophoto map(DOM)and digital elevation model(DEM).According to DOM and laser point cloud elevation data,users can finally obtain digital topographic maps,image maps and various thematic data results with different scales such as 1:500,1:1000 and 1:2000,which greatly simplifies the workflow of photogrammetry processing and makes the processing results more accurate and reliable.

  Application of UAV and airborne LiDAR in forestry investigation
。Airborne LiDAR technology provides a new scheme for obtaining spatial information with high temporal and spatial resolution.In forest resources survey,it can directly measure the height of vegetation.Using it to obtain the vertical structure information of forest area can make up for the shortcomings of other remote sensing methods.The integration of other remote sensing technologies and airborne LiDAR technology can provide more comprehensive and accurate forest parameters.

  UAV LiDAR is suitable for forest information statistics in a small area.It is mainly used for forest resources investigation with moderate operating area(tens of square kilometers)and small topographic change.UAV LiDAR is flexible and convenient to operate,and can solve the problem of difficult road access.
