【摘要】：隨著人們對(duì)地理環(huán)境理解力的提高和對(duì)測(cè)繪需求的急劇增長(zhǎng)，使無人機(jī)與測(cè)繪的關(guān)系越來越緊密。無人機(jī)具有高時(shí)效、高分辨率、重復(fù)使用、低成本、低損耗且風(fēng)險(xiǎn)小等諸多優(yōu)勢(shì),是傳統(tǒng)遙感監(jiān)測(cè)平臺(tái)所無法比擬的，越來越受到研究者和生產(chǎn)者的青睞。為國(guó)土資源調(diào)查、災(zāi)害防治和國(guó)民經(jīng)濟(jì)建設(shè)規(guī)劃等，提供可靠依據(jù)；在其他數(shù)據(jù)的精度、現(xiàn)勢(shì)性和完整性的評(píng)價(jià)方面都有很好的作用；而且可以根據(jù)它的信息，進(jìn)行地圖的修測(cè)更新。然而無人機(jī)空中三角測(cè)量系統(tǒng)中影像像幅小，數(shù)量多，造成工作量大，像片重疊度，航線彎曲度不規(guī)則，這些問題都成了國(guó)內(nèi)外攝影測(cè)量系統(tǒng)面對(duì)的問題，對(duì)于這些問題如何在實(shí)際生產(chǎn)中制作高質(zhì)量數(shù)字正射影像圖也有一定的研究?jī)r(jià)值。為解決無人機(jī)影像在數(shù)據(jù)處理過程中存在的問題,論文主要在以下方面展開研究1： （1）本文首先論述了無人飛行器低空遙感系統(tǒng)組成和應(yīng)用現(xiàn)狀，對(duì)無人機(jī)數(shù)據(jù)質(zhì)量進(jìn)行了探討； （2）介紹了數(shù)字?jǐn)z影測(cè)量的理論基礎(chǔ)，本文實(shí)驗(yàn)是基于德國(guó)空三加密軟件Inpho，因此對(duì)于Inpho軟件在空三加密過程中使用的各種算法進(jìn)行了介紹。 （3）對(duì)數(shù)字正射影像圖的制作流程進(jìn)行了闡述，分析了數(shù)字正射影像圖生產(chǎn)工藝中存在的問題和導(dǎo)致其成果質(zhì)量不高的原因，指出了數(shù)字正射影像圖制作流程中決定最終成果質(zhì)量的關(guān)鍵環(huán)節(jié)，通過實(shí)例具體展現(xiàn)了這些關(guān)鍵環(huán)節(jié)中可能存在的問題，并且針對(duì)這些問題給出了相應(yīng)的解決方法，，從而總結(jié)出了在實(shí)際生產(chǎn)中制作高質(zhì)量數(shù)字正射影像圖的方法和技巧。
[Abstract]:With the improvement of people's understanding of geographical environment and the rapid increase of the demand for surveying and mapping, the relationship between UAV and surveying is becoming more and more close. UAVs have high efficiency, high resolution, reuse and low cost. The advantages of low loss and low risk are unparalleled by the traditional remote sensing monitoring platform, and are more and more favored by researchers and producers. It provides reliable basis for land and resources investigation, disaster prevention and planning of national economic construction. It plays a good role in evaluating the accuracy, present situation and integrality of other data, and can update the map according to its information. However, in the aerial triangulation system of UAV, the image size is small and the number of images is large. These problems have become problems faced by photogrammetry systems both at home and abroad, which result in heavy workload, overlap of photographs and irregular curvature of routes. In order to solve the problem of UAV image processing in the process of data processing, this paper mainly studies in the following aspects: 1. The research on how to make high quality digital orthophoto image in actual production is also valuable. In order to solve the problem of UAV image in the process of data processing, this paper mainly studies in the following aspects: 1. Firstly, the composition and application status of UAV low altitude remote sensing system are discussed, and the data quality of UAV is discussed. This paper introduces the theoretical basis of digital photogrammetry. The experiment in this paper is based on the German Space-3 encryption software Inpho. so the various algorithms used by Inpho software in the process of space-triple-encryption are introduced. In this paper, the production process of digital orthophoto image is expounded, and the problems existing in the production process of digital orthophoto image are analyzed, and the reasons leading to the low quality of the digital orthophoto image are analyzed. This paper points out the key links in the process of making digital orthophoto image that determine the quality of the final result, shows the possible problems in these key links by examples, and puts forward the corresponding solutions to these problems. The methods and techniques of making high-quality digital orthophoto images in actual production are summarized.
