Claim 14:
15. A method for monitoring an exhaust gas of a vehicle comprising:
determining in a preheating determination operation whether analyzing a state of an engine of a vehicle is possible on the basis of color information of an exhaust gas;
collecting image data of a rear of the vehicle in an image input operation when it is determined in the preheating determination operation that it is possible to analyze the state of the engine;
using supervised learning, analyzing, in an image analysis operation, the image data collected in the image input operation and extracting color information corresponding to an exhaust gas region included in the image data, wherein the supervised learning is trained on data comprising pairs of image data with a correct color determination; and
determining in an analysis processing operation the state of the engine of the vehicle based on the color information extracted in the image analysis operation;
wherein the analysis processing operation comprises:
determining, in a first determination operation, whether the color information corresponds to preset first color information;
analyzing, in a first analysis operation, the state of the engine of the vehicle as a normal state when it is determined in the first determination operation that the color information corresponds to the first color information; and
classifying, in a subsequent analysis operation, the color information as one of preset second color information to fourth color information when it is determined in the first determination operation that the color information does not correspond to the first color information, and providing one of previously stored first notification generation information to third notification generation information, which corresponds to the classified color information through a connected display.
