Description

technical field [0001] The invention belongs to the technical field of drone photography, and particularly relates to an infrared dual-light photography system for drones. Background technique [0002] An infrared thermal imager uses an infrared detector and an optical imaging objective to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector to obtain an infrared thermal image. The distribution field corresponds; the camera uses the linear propagation properties of light and the law of refraction and reflection of light, and uses photons as the carrier to transfer the light information of the scene at a certain moment to the photosensitive material in the form of energy through the camera lens, and finally becomes a photosensitive material. visible image. When the high-voltage equipment fails ionization discharge, different infrared radiation energy will be generated according...
