摄像头测试软件imatest Master

详细介绍

imatest Master（企业*版）

 详细介绍
Measure device sharpness （MTF）, perceptual sharpness （SQF）, color response, noise, dynamic range, tonal response, lens flare （veiling glare）, lens distortion, lens vignetting, and sensor nonuniformity with SFR, Colorcheck, Multicharts, Stepchart, Distortion, and Light Falloff. Imatest是美国Imatest LCC公司开发的专业数码影响评测软件，涵盖了MTF、SQF、SFR 、色彩还原、杂讯、动态范围等图像指标测试，兼用于数码相机、打印机、扫描仪等进行完整测试内容。软件系统建立于*的工程数学运算平台Matalab，具有相当高的可靠性，制图内容相当有深度。
 功能描述
用途：图像质量分析、相机检测、镜头检测
应用行业：摄影、摄像、工业视觉、科研
简介：
  Imatest master是*功能的软件，即可用于检测数字相机、摄像机、工业相机拍摄的图像质量，也可用于交流检测结果。其功能包括：
·SFRplus:可以与SFRplus测试卡配合使用，检测MTF,横向色差，畸变，阶调响应和颜色还原。
·SFR: 配合测试卡，可检测相机和镜头的锐度，噪音，色差。可以在相对条件下比较不同相机的表现。比较的zui小区域可达10X10个像素。
·MTF:使用SFR的结果比较不同相机、镜头和影像系统的MTF性能。
·Stepchart:配合灰阶测试卡检测相机的阶调响应，噪音，动态范围。还可用于检测曝光的准确性，镜头眩光。
·Distortion:检测镜头的畸变，使用可打印的正方形和矩形网格计算矫正系数。
·Uniformity:检测镜头的光分散（格晕光阑），检测多种图像传感器的不均匀性，包括色彩阴影，具体的噪音分部，可见的不均匀性，灰尘污点。标识出有问题的像素。 显示选项包括叠生在图像上的轮廓线，或伪彩色的色条。
·Test Charts:可以生成图像文件用打于打印测试图。生成的测试卡包括SFR斜边图像，星形测试图，各种频率和反差的图样。可选项包括：反差，高光色彩，正弦线和条纹模式。可输出位图或 可绽放矢量图 （SVG）。
·Print:打印检测，可以检测打印机、纸张、墨水的质量，包括色彩响应，色域，阶调响应，zui大密度，ICC描述文件和呈色意图。
 




Imatest IT

 详细介绍
用途：图像质量分析、相机检测、镜头检测 应用行业：摄影、摄像、工业视觉、科研 简介： ImatestIT软件是一套专门用于检测图像质量的控制系统，与Imatest Master联合使用。使用Imatest IT,你可以在生产线上使用与研究室中相同的检测引擎来测量图像质量。 Imatest IT是一套独立运行的DOS程序，由检测系统调用。它们与Imatest Master有相同的功能。但是他们可以自动运行，不需要使用者的介入，适合于在全自动系统中使用。此检测系统通过DS命令行与IT程序互动，输入的是图像文件和INI控制文件，输出文件XML或可读的Excel文件.CSV格式。如果需要也可以保存图表。尽管ImatestIT可以独立运行，但我们强烈建议使用者应同时安装有Imatest Master软件。 Imatest IT EXE 软件包，包括5个 DOS 可执行程序: 色彩检测（Colorcheck） 畸变（Distortion） SFR （but not SFRplus） 阶调（Stepchart） 均匀度（Uniformity）
 功能描述

Imatest IT is available in two versions: IT/DLL and IT/EXE. Both versions, described below, have the same functionality as the corresponding modules in Imatest Master, but they operate without user intervention, making them suitable for integration with automated systems. Although IT/DLL and IT/EXE operate independently of Imatest Master, it is strongly recommended that IT/DLL users have at least one Master installation on site to support the process of defining execution parameters and default settings.





 

Imatest IT/DLL is a software library designed for integration with other software systems. Imatest IT/DLL allows developers to access Imatest’s powerful analysis tools via calls to Imatest functions residing in a Dynamic Link Library （DLL）.

Imatest IT/DLL is a complete package featuring not only the module libraries, but also extensive support documentation including detailed function definitions and sample code, as well as basic example programs that interface with modules.

As shown in the diagram to the right, IT/DLL takes image files as input, returns customizable test results, and outputs detailed test result files. Imatest IT/DLL is linked to other software programs and function calls are executed to invoke desired image analysis algorithms.

Detailed instructions on using IT/DLL are available upon request.

Imatest IT/EXE is a set of standalone programs initiated by DOS calls from the test system. IT/EXE modules are represented by the blue box in the figure on the right. The test system interacts with the IT programs through files specified in the DOS command line: the primary inputs are an image file and an INI control file （created and saved by Imatest Master during setup）. The output is data files in XML or Excel-readable .CSV format. Figures can be saved if desired.

Image Sensor（IS） Edition

 详细介绍
 
Imatest’s IS Edition, which has all the features of Imatest Master, also offers the ability to load images directly from Aptina’s Demo Camera Software, DevWare, and from OmniVision’s OVTA Tool 2009. This eliminates the need to capture images separay and load them individually into Imatest, dramatically improving productivity. Using the SFRplus capability of Imatest, and the SFRplus test chart, the process of configuring image sensors with DevWare or OVTA Tool 2009 is easier and faster than ever. Imatest邀请 Aptina DevSuite的用户使用具有DevWare功能的Imatest软件。除了Imatest Master软件的全部功能之外，具有DevWare功能的Imatest软件还提供了直接从Aptina Imaging公司的相机软件Devware或者OmniVision的OVTA 2009工具软件中导入图像的功能。这样减少了分别采集图像，再置入Imatest软件的过程，*的提高了效率。 版的Imatest支持SFRplus功能，与SFRplus测试卡同时使用。在检测CMOS图像传感器时比以往更加快速。
