After processing and analysis, it identified the target object, revealed the geometric shape and size of the target object, the relationship between them, and the laws of change. It was also known as remote sensing technology. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Laser remote sensing and photogrammetery
Laser remote sensing was a technology that used lasers to detect targets. For example, laser atmospheric remote sensing was a technology and method that used lasers to detect the atmosphere. It was a type of active atmospheric remote sensing. It used the various characteristics of scattered waves to retrieve the characteristics of atmospheric fumes, spatial and temporal distribution, and measure atmospheric turbulence and average wind field. Photogrammetry was a technique that used a combination of a camera and film to measure the shape, size, and spatial position of a target. It used the image of the object to reconstruct the spatial position and three-dimensional shape of the object to obtain the spatial information of the ground or other objects. It had experienced three stages of development: simulation, analysis, and digital. The core problem was to use two-dimensional images to obtain the three-dimensional coordinates of the target. In the field of surveying, the two had different application directions. Laser remote sensing focused on using the interaction between laser and target to obtain target information, while photogrammetry focused on using images to reconstruct the space and shape of the target. At the same time, in some scenarios such as mine surveying, it was possible to combine laser radar (a device embodiment of laser remote sensing) with photogrammetry-related technology to complete the measurement task. For example, Huachi navigation used the combination of drone and airborne laser radar measurement technology to overcome the limitations of traditional measurement equipment and provide efficient and accurate measurement results. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

photography and materials
Photographs were closely related to materials. From the perspective of a photographic material, it was an optical information recording material. After receiving optical information (such as images), it could use physical or chemical methods to fix, magnify, and store the information. The photographic material usually consists of one or more layers of photographic cream coated on a carrier. According to the chemical composition, it can be divided into silver salt and non-silver salt; according to the processing method, it can be divided into conventional methods and unconventional methods; according to the color sensitivity range, it can be divided into positive film, pan-color film, infrared film, etc.; according to the use, it can be divided into microfilm, X-ray film, motion picture film, astronomical film, aerial film, holographic film, etc.; according to the requirements of the photo production process, it can be divided into negative film, positive film, intermediate film, reversal film; according to the type of film base, it can be divided into photographic dry plate, photographic film, photographic paper, etc. The main components of the silver salt photographic material were silver bromate, silver chlorideand silver iodinate, which were traditional photographic materials that were more mature and widely used. For example, the photographic cream in black-and-white photography was made up of crystallites of silver halide dispersed in gelatins. The silver halide was decomposed into silver and halo under the effect of light. Among them, the sensitivity of silver chloride-based was the lowest, silver bromide-based was medium, and silver bromide-based with silver iodinate had the highest sensitivity. The printing paper used a very slow silver chloride-based cream, and the magnifying paper contained silver bromide-based or silver chloride-based cream, and the silver halide itself was only sensitive to blue-purple light. In addition to photographic materials, photographic materials also included developing and fixing materials as well as auxiliary materials such as filter. In terms of photography learning and practice, there were also many books related to photographic materials for reference, such as Photographic and Plate Making Photographic Materials, which involved photography techniques and techniques, silver salt photographic materials and their application in plate making, and non-silver salt photographic materials and their application in plate making. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Materials for photography
Cloud intelligent remote photography
Based on context alone The cloud intelligent remote camera was a function that could remotely control a device to take photos with the help of cloud technology. In terms of principle, devices (such as smart phones, smart cameras, etc.) were connected to the Cloud Virtual Machine through the network. The user could send a photo command to the Cloud Virtual Machine using a matching application or a web-based interface. The Cloud Virtual Machine then forwards the command to the target device, and the device performs the photo operation after receiving the command. From the perspective of application scenarios, in the field of security monitoring, cloud intelligent remote photography can be used for real-time monitoring and capturing abnormal images; in the home scene, it can be used to remotely check the situation at home, such as checking the activities of pets; in some scientific research or natural observation scenes, it can prevent people from getting close to the observed object to obtain images. However, cloud intelligence remote photography also faced some challenges. For example, unstable network connection may cause delay or failure of command transmission. Security and privacy protection during data transmission also needed to be paid attention to to prevent illegal acquisition or modification of photos. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Rainfall Inversion in the Source Region of the Yellow River Using Remote Sensing
Satellite remote sensing is an important source of rainfall data in the source area of the Yellow River, which has high spatial and temporal resolution, wide coverage, and continuous spatial estimation. The researchers of the Institute of Natural Resources and Geography of the China Academy of Sciences had systematically evaluated the data accuracy of the Multi-Satellite Rainfall Joint Inversion (IMERG) product of the New Generation Global Rainfall Project (GPM) in the source area of the Yellow River. The results showed that the non-real-time data corrected by the ground station (imerg final run, or imerg-f) had higher data quality than the near-real-time satellite rainfall data (IMERG early run, or IMERG Late run, or imerg-l). In the source area of the Yellow River, all three kinds of IMERG products could better describe the spatial distribution of rainfall. The data accuracy increased with the gradual wetness of climate conditions and the increase of time scale, but the estimation of stronger and weaker rainfall events and solid rainfall in autumn and winter was still insufficient. In the past, there were also studies that used the 1993, 1995, 1997 and 1998 NOAA-Avhrr remote sensing data and the rainfall observation data of the same period to analyze the spatial distribution of rainfall and the relationship between floods. At the same time, they also analyzed the temporal variation law and spatial variation characteristics of rainfall in the source area of the Yellow River. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What do you think of the scale of photogrammetry and remote sensing technology?
In the ideal situation where the photo is horizontal and the ground is also horizontal, the scale of the aerial photo can be defined as the ratio of the line on the photo to the corresponding horizontal line on the ground like the map scale. In the ideal situation, the scale of the entire photo is the same. This was a basic concept of scale in photogrammetry and remote sensing technology. However, in reality, it may be affected by many factors, such as the tilt of the photo, terrain undulations, etc., which may cause the scale to change at different positions in the photo. The scale situation will be more complicated, and it requires a comprehensive technical means and data to accurately judge. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
