1. An allergenic species broadcasting method, characterized in comprising:
training a plant recognition model by a remote server, and in response to receiving an image from a mobile device in the remote server, performing following steps by the remote server, comprising:
identifying species information and growth stage information of a plant in the image by the plant recognition model;
in response to determining that the plant belongs to one of a plurality of allergenic species, treating the plant as an allergenic species, acquiring sensitization information of the allergenic species and location information of the allergenic species, and pushing protection information to a related user according to the sensitization information of the plant and the location information of the plant;
in response to not identifying any one of the plurality of allergenic species in the image received from the mobile device at a current location within a set time period, but a historical record recording having a previously recorded allergenic plant belonging to one of the plurality of allergenic species at the current location, comprising:
obtaining the sensitization information and sensitization period information of the previously recorded allergenic plant, and pushing the protection information indicating that a previously recorded allergenic species is likely to exist at the current location to the related user during the sensitization period;
when subsequently another user arrives at the current location, guiding the another user to take a plurality of photos or panoramic photos covering a range of 360 degrees; and
after receiving the plurality of photos or panoramic photos covering the range of 360 degrees, identifying whether there are still other previously recorded allergenic plants and updating a related allergenic plant information database by the plant recognition model,
wherein training the plant recognition model by the remote server comprises following steps:
(a) obtaining a sample set comprising a predetermined number of species images annotated with a plurality of feature information;
(b) determining a plurality of species images from the sample set as a training set and determining a plurality of species images different from the training set from the sample set as a test set;
(c) training the plant recognition model using the training set;
(d) determining a model accuracy of the trained plant recognition model using the test set;
(e) adjusting at least one of the training set and the plant recognition model when the model accuracy is less than a preset accuracy, and re-performing steps (c), (d), and (e) until the model accuracy is not less than the preset accuracy, thereby terminating training of the plant recognition model.
