Method and device for quickly measuring cleanliness of vehicle fuel oil based on image recognition

The invention provides a method and a device for quickly determining the cleanliness of vehicle fuel oil based on image recognition. The determination method comprises the following steps: establishing a fuel oil spraying plate database, wherein cleanliness levels and color feature and texture feature images corresponding to the cleanliness levels are stored in the fuel injection plate database; acquiring a spraying plate image of the to-be-detected fuel oil and extracting color features of the spraying plate image; carrying out texture feature calculation on the injection plate image of the to-be-detected fuel oil to obtain a texture feature image of the injection plate image of the to-be-detected fuel oil; and comparing the color feature and texture feature images of the to-be-detected fuel injection plate image with color feature and texture feature images stored in a fuel injection plate database to obtain the cleanliness level of the to-be-detected fuel injection plate image.
