Detecting Nuclear Radiation with an Uncovered CMOS Camera & a Long-Wavelength Pass Filter

In this article, we propose a method to detect nuclear radiation based on a CMOS camera and a long-wavelength pass filter. Firstly, we capture videos and gain image dataset through the camera with and without the filter individually. Then the inter-frame difference algorithm and Gaussian smoothing method are used to reduce the interference of moving objects and visible light to the images. At last, a series of thresholds were selected to test the validity of our detecting method on validation set. The experimental results present that the promoted method can effectively detect nuclear radiation.
