Abstract: This application provides an intelligent light switching method and system, and a related device. One example method includes: The intelligent light switching system obtains an image, where the image comprises lamp source information; calculates an ambient light brightness value corresponding to the image; classifies, based on the lamp source information, a lamp source included in the image to obtain a classification result; and switches to a high beam or a low beam based on the ambient light brightness value corresponding to the image and the classification result.
