Abstract
The present disclosure provides a method and device for identifying a light source. The method includes as follows. M stripe sets in an image may be detected. A first energy spectrum data corresponding to each of M stripe sets may be obtained. A second energy spectrum data corresponding to each light source in a database may be obtained. The database may include K light sources, and the energy spectrum data corresponds to an identity of the light source. A correlation coefficient between the second energy spectrum data and the first energy spectrum data may be calculated to obtain M*K correlation coefficients. The identity of each stripe set corresponding to the light source in the database may be determined according to the M*K correlation coefficients. With this disclosure, the tracking of the light source emitted by a controller can be achieved.
