Abstract
Provided are an exhaust gas monitoring system and method for allowing a driver to monitor a state of an exhaust gas discharged from a vehicle during driving without getting out of the vehicle, thus improving convenience, and improving driving safety by diagnosing a state of an engine.
Claims17
An exhaust gas monitoring system comprising:
- an initial determiner configured to determine whether analyzing a state of an engine of a vehicle is possible on the basis of color information of an exhaust gas;
- an image collector configured to perform an operation to collect image data of a rear of the vehicle;
- an image analyzer configured to analyze the image data and output color information corresponding to an exhaust gas region included in the image data;
- and
- an analysis processor configured to analyze the state of the engine of the vehicle to produce an analysis result based on an analysis of the color information from the image analyzer,
- wherein the image collector collects the image data of the rear of the vehicle only when the initial determiner determines analyzing the state of the engine is possible based on the color information of the exhaust gas;
- wherein the analysis processor comprises:
- a first determiner configured to determine whether the color information from the image analyzer corresponds to preset first color information on the basis of the analysis result;
- a second determiner configured to receive information related to a current state of the engine and determine whether the current state corresponds to a regeneration mode when the first determiner determines that the color information from the image analyzer does not correspond to the first color information;
- and
- a first processor configured to process the state of the engine as a normal state when the second determiner determines that the current state corresponds to the regeneration mode.

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
- receiving, in a second determination operation, information related to a current state of the engine of the vehicle and determining whether the current state corresponds to a regeneration mode when it is determined in the first determination operation that the color information does not correspond 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.
