数字图像处理在数字摄影测量技术中的应用与实践

数字图像处理在数字摄影测量技术中的应用与实践数字图像处理在数字摄影测量技术中的应用与实践 摘要：数字图像处理是指将图像信号转换成数字信号并利用计算机对其进行处理的过程。图像处理最早出现于 20 世纪 50 年代，当时的电子计算机已经进展到一定水平，人们开始利用计算机来处理图形和图像信息。数字图像处理作为一门学科大约形成于 20 世纪60 年代初期。早期的图像处理的目的是改善图像的质量，它以人为对象，以改善人的视觉效果为目的。图像处理中，输入的是质量低的图像，输出的是改善质量后的图像，常用的图像处理方法有图像增强、复原、编码、压缩等。如今，数字图像处理正与当今社会的各个方面紧紧相连，密不可分。让我们一起来认识数字图像处理技术。 关键词：基本概况及简要进展 ，常用方法， 实际应用 ，未来进展 Abstract: the digital image processing is to point to will image signal converted into digital signals and use the computer to the treatment of the process. Image processing first appeared in the 1950 s, when the electronic computer has developed to a certain level, people began to use computers to graphics processing and image information. Digital image processing as a subject about formed in the early 1960 s. The purpose of the early image processing is to improve the quality of the image, it with artificial object, to improve the visual result of the person for the purpose. The image processing, the input is the image quality is low, the output is to improve the quality of the images, common image processing method has image enhancement, recovery, coding, compression, etc. Nowadays, digital image processing is and the various aspects of society closely linked, inseparable. Let us know the digital image processing technology.
