Abstract : in this paper , presented is a computer system which will be ofvalue to the application of close - range photogrammetry to engineering 文摘:介紹了采用數(shù)字化攝影結(jié)合微機軟件解決工程問題的方法及實例。
Utilizing the rectification technology of geometric distortion in vehicle license recognition system based on image processing and close - range photogrammetry theory is important in increasing system reliability 依據(jù)圖像處理和近景攝影測量原理,把圖像幾何畸變校正技術(shù)應(yīng)用于汽車牌照識別系統(tǒng)中,將會明顯提高系統(tǒng)的識別率。
Therefore , the application field of close - range photogrammetry is widened and the quality of measurement result is improved . the accomplishment of this research is certain to prosper the progress of photogrammetry technique 由此拓寬了近景攝影測量的應(yīng)用領(lǐng)域,并提高了測量成果的質(zhì)量,這一研究成果必將推進攝影測量技術(shù)的進步。
The unionist of image collection , digitalization and measurement in the process of photogrammetry is achieved where close - range photogrammetry machine and digital photogrammetry software designed by myself are put into use 使用近景攝影測量機和自行開發(fā)的數(shù)字攝影測量軟件,實現(xiàn)了攝影測量過程中圖像采集、數(shù)字化和測量等工作的一體化。
In the information era of digital , intelligence and network , complete digital photogrammetry machine is applied to dispose of and analyze image and build measurement system of measured object ' s 3 - d model based on the close - range photogrammetry technique in this paper 在當今數(shù)字化、智能化和網(wǎng)絡(luò)化的信息時代,基于近景攝影測量技術(shù),應(yīng)用完全數(shù)字化的攝影測量機,處理和解算攝影圖像,并實現(xiàn)了建立被測量物體三維模型的測量系統(tǒng)。
As to the automatic & digital trend of photogrammetry development , the designed project of close - range photogrammetry machine is proposed , in this project , the automation degree in the process of image collection in close - range photogrammetry is improved with the use of computerized control technique and image process technique 針對攝影測量發(fā)展的自動化、數(shù)字化趨勢,提出了近景攝影測量機的研制方案,運用計算機控制技術(shù)和圖像處理技術(shù),提高了近景攝影測量中圖像獲取過程的自動化程度。
The emergence of the ordinary digital images ( which in this paper means the digital images acquired by common non - metric digital cameras ) , resolved the the problem of acquiring images quickly on the spot , and lowered the requirement for equipments and skills in photogrammetry , so that made photogrammetry a whole digital process . but all current ways to the measurement of ordinary images are based on dlt or bundles theory , which both require a lot of control points distributing properly , and are inapplicable . in order to increase the adaptability and accuracy of digital close - range photogrammetry based on common digital cameras , researches and experiments have been done on these methods in this paper , as following : 1 普通數(shù)碼影像(在本文中主要指采用普通非量測數(shù)碼相機獲得的數(shù)碼影像)的出現(xiàn),解決了現(xiàn)場快速獲取影像的問題,且降低了近景攝影測量作業(yè)對設(shè)備及技能的要求,并使攝影測量過程成為全數(shù)字流程,但現(xiàn)有的對普通數(shù)字影像的量測處理算法均是基于直接線性變換或光線束理論的,存在像控點要求多、分布要求高、不適宜應(yīng)用的缺點。
