Abstract: The infrared false-color imaging detection technology has been paid attention to. With the development of the remote sensing technology in recent years, the infrared false-color imaging detection has widely been used in the detection of vegetation, ground resources and aquatic pollution. And with the development of digital technology, the traditional photographic film would phase out. The false color film has stopped production in our country. A solution of using digital camera and near-infrared filter to achieve infrared false-color imaging is proposed by analyzing the principle of infrared false-color imaging by traditional false color film, and the algorithm is verified by experiment.
