VIC-3D IR system

VIC-3D红外系统可方便地同时采集白光和红外图像,以进行热和表面应变分析。 数字图像相关技术(DIC)的应变数据现在可以与IR温度数据同步和标定。 这个完全集成的成像系统能够精确地标定两个成像系统,使温度和应变数据可以在同一个坐标系中精确显示。 该系统为交钥匙服务提供,可随时使用,包括现场安装。 温度成像功能也可以添加到任何现有的VIC-3D系统中以提高功能。 有关此产品的更多详细信息以及查看应用示例,请下载我们的VIC-3D红外系统手册

The VIC-3D IR system conveniently allows white light and IR images to be simultaneously acquired for thermal and surface strain analysis.  The digital image correlation (DIC) strain data can now be synchronized and calibrated with IR temperature data.  This fully integrated imaging system accurately calibrates the two imaging systems so temperature and strain data are accurately displayed in a common coordinate system.  The system is turn-key and ready to use right out of the box, and includes onsite installation, and one year of unlimited technical support with every purchase.   The thermal imaging capability may also be added to any existing VIC-3D system for increased functionality.  For more details about this product, and to see an application example, please download our VIC-3D IR System brochure.

 

技术概述 Technology Overview

 

VIC-3D红外系统是3D数字图像相关系统产品的新成员。 VIC-3D红外系统将红外(IR)摄像头与白光DIC摄像头集成在一起,使温度数据可以与全场应变数据一起进行精确分析。该系统通过将来自IR相机的图像与来自立体DIC系统的图像同步,然后校准所有三个相机以使得温度和应变数据处于同一坐标系中来工作。使用VIC-Snap IR软件可以简化标定过程,该软件允许用户采集同步的单张IR图像进行标定,并以恒定速率采集多张图像进行准静态测试。其成果就是易于使用的交钥匙温度/应变耦合测量系统,它利用数字图像相关技术来同时准确测量温度和应变,而无需与样品接触。温度和应变数据可以在整个区域或指定位置进行查看,分析和提取。

The VIC-3D IR System is a new addition to the 3D digital image correlation system.  The  VIC-3D IR System integrates an infrared (IR) camera with the white light DIC cameras enabling temperature data to be accurately analyzed alongside full-field strain data.  The system works by first synchronizing images from the IR camera with images from the stereo DIC system, and then calibrating all three cameras so that the thermal and strain data are in a common coordinate system.  This calibration procedure has been streamlined using the VIC-Snap IR software, which allows the user to capture synchronized single images for calibration, and multiple images at a constant rate for quasi-static testing.  The result is an easy to use turn-key thermal imaging system that utilizes the digital image correlation technology to accurately measure temperature and strain concurrently without any contact with the sample. Thermal and strain data can be viewed, analyzed, and extracted over the entire field or at precise locations.
