摘要:
利用红外热成像系统可以将物体的热分布转化成可视图像,并在监视器上以灰度级的形式显示出来,进而得到被测物体的温度分布场。由于人眼对彩色的分辨能力高于黑白图像,所以对红外热图像进行伪彩色编码更利于人眼识别和获取图像中的有用信息。基于FPGA和ADV7127,提出了一种伪彩显示方法,对来自红外热像仪输出的数字图像按照PAL制标准进行视频编码,并对数据进行彩虹编码或者重金属编码等处理,经过AD转换将编码后的数字图像转化为彩色PAL制模拟信号并由电视机进行显示。所实现的红外图像伪彩显示设计具有低功耗,灵活性强,便于系统小型化等特点。
Abstract:
The thermal distribution of objects can be transformed into the visual pictures by the infrared thermal imaging system and displayed on the monitor in grey level or pseudo-color, thus the temperature distribution of objects can be obtained. As the resolving power of the human eye to color image is higher than to monochrome image. Pseudo-color-coded infrared thermal image is more conducive to human eye to identify and obtain useful information in the image. According to the thermal imaging principle of temperature measurement and the characteristics of infrared images, the pseudo-color coding of infrared image is studied in this paper. The pseudo-color coding is based on FPGA and ADV7127 and the standard of the video coding must fit with the PAL system. After processing of Rainbow coding or heavy metals coding, the coding image with color will be showed on the monitor. The infrared thermal imaging pseudo-color system designed in the paper has low power consumption, more flexibility, system miniaturization characteristics.
