The phrase "thermal imager" is correct and usable in written English.
You can use this phrase to refer to a device that detects the infrared radiation emitted by objects, allowing them to be seen in darkness. For example: The firefighter used a thermal imager to locate people trapped inside a burning building.
In human body extraction module, temperature frames obtained from the thermal imager are processed with image processing techniques to obtain intact human body contours and silhouettes.
To this end, the temperature images captured from a thermal imager are binarized by Otsu's method firstly.
The process of human body extraction is depicted in Fig. 6. Figure 6a shows the temperature images captured from the thermal imager, Fig. 6b shows the Otsu's binarization results, and Fig. 6c shows the results of morphological closing operation.
For comparison, Fig. 2a shows the images obtained by a CCD camera in a dusky environment, whereas Fig. 2b shows the images obtained by a thermal imager in the same environment.
From the tower, Abbas scanned the road and peered into a thermal imager that showed a night-vision image of the cemetery, from which someone had shot at the base earlier in the day.
However, the infrared thermal imager is a two-dimensional plane imaging infrared system.
That now looks set to change as a number of efforts aim to put the technology in far more hands, by linking it to mobile phones.In late 2012, Andy Rawson decided to build his own crude thermal imager, which he attached to his phone, overlaying a thermal image with that from his phone's own camera.
To remedy this problem, a fall detection system using a thermal imager (see Fig. 1) to capture the images of human bodies is proposed in this paper.
The thermal imager with original resolution of 640×480 was first used to establish the thermal imaging system.
