Fig. 3 shows a block diagram of the structure of the odor type determination module in the simulated odor delivery system, wherein the odor type determination module 12 comprises:
the color value determining unit 121 is configured to traverse a pixel point in the region image, acquire a color value of the pixel point, and convert the color value of the pixel point according to a preset conversion formula to obtain a characteristic value of the pixel point;
a comparison unit 122, configured to sequentially read feature values of adjacent pixels, calculate a feature value difference between adjacent pixels, and compare the feature value difference with a preset tolerance;
a marking unit 123, configured to mark the pixel point when the feature value difference is greater than the tolerance, and continue to read a next adjacent pixel point when the feature value difference is smaller than the tolerance;
a connecting unit 124, configured to generate a feature profile based on the marked pixel points, and determine a feature region according to the feature profile.
The above-mentioned content defines the process of contour recognition, and firstly, the feature transformation is performed on the region image according to the preset formula, which is performed because the region image is often an RGB image, each pixel point has three independent values, and the three independent values are very inconvenient in the operation process, so that the feature transformation is required, the feature transformation process may be a Gray scale transformation process, and then the corresponding transformation formula may be Gray (Red 0.3+ Green 0.59+ Blue 0.11).
The determination of the feature profile can then be used to reference the magic wand tool in Photoshop, which has the principle of marking the profile with tolerances.
Further, the odor type determination module further comprises:
the sorting unit is used for calculating the number of pixel points of the characteristic region and sorting the characteristic region according to the number of the pixel points;

and the first processing execution unit is used for determining the odor type according to the characteristic object.
On the premise of determining the characteristic contour, the specific identification process is a comparison process, the air parameters determine the environmental information at first, the capacity of the air parameters for determining the environmental information is generally low, and only indoor or outdoor can be distinguished; in particular, during the comparison, the elements in the library of reference images are limited, which are also relevant to the scent type of the scent releaser, and if no feature is identified, it is not considered anymore, because the scent releaser is also unable to provide the scent of the feature.
Fig. 4 shows a block diagram of the structure of a simulation time determination module in the simulated scent delivery system, wherein the simulation time determination module 13 comprises:
a scale determining unit 131 configured to read a feature, read an image size and a reference size of the feature, and determine a scale according to the image size and the reference size;

and a second processing execution unit 133, configured to read a wind direction parameter and a wind speed parameter in the air parameters, and determine the odor simulation time according to the wind speed parameter and the actual distance.
The process of determining the actual distance from the image requires a scale to be determined, the scale can be determined by the feature, and it is worth mentioning that if the feature is not present, the above process of calculating the odor simulation time is unnecessary, and no calculation is needed.
