[0052] In one embodiment, Figure 2 As shown, the main controller 2 is configured with a communication module 23, and the communication module 23 is used to connect to the mobile terminal through the communication network and send the feedback reward to the verified mobile terminal.

[0053] The working principle and beneficial effects of the above technical solution are as follows: by setting up a communication module, this solution can communicate with a mobile terminal (such as a mobile phone) through the network. On this basis, it can use electronic payment methods to feedback the consumer's mobile terminal with feedback rewards for implementing empty bottle recycling behavior, avoiding the difficulty of physical payment, and can also achieve diversification of feedback reward forms, further enhancing the correct guidance of consumers' environmental protection behavior.

[0054] In one embodiment, Figure 1 and Figure 3As shown, the main controller 2 is connected to the operating unit 3, which includes an operating module 31 and a display screen 32.

[0064] In one embodiment, the delivery recognition module performs image processing on the delivery image as follows:

[0065] Sort each image frame contained in the projected image according to the order of acquisition time;

[0066] Calculate the similarity of each adjacent image frame based on the sorted pairs;

[0067] Compare the similarity of each adjacent image frame with a preset threshold, find all adjacent image frames whose similarity is less than the preset threshold, obtain the middle time point of the acquisition time points of each two adjacent image frames whose similarity is less than the preset threshold, and use the middle time point as a grouping basis to group the image frames included in the delivery image; regard the image frames in the same group as the image frames of the same delivery action, and regard the number of image frame groups as the number of delivery times;

[0068] Determine the high-definition area of ​​the captured image according to the shooting range and angle set by the digital camera;

[0069] Select a group of image frames to perform motion path analysis on the delivery action, determine the action time point closest to the center of the high-definition area in the motion path, and calculate the time division ratio of the action time point closest to the center of the high-definition area to divide the shooting period of the same group of image frames;

[0073] The working principle and beneficial effects of the above technical solution are as follows: the solution calculates the similarity of each adjacent image frame in the delivery image, adopts a preset threshold as a judgment standard, determines the intermediate time point for distinguishing the adjacent delivery actions of consumers for bottle recycling, and groups the image frames according to the delivery actions, thereby accurately calculating the number of delivery times; each group then selects a representative image frame to identify the type and number of bottles delivered in each delivery action, and combines the number of deliveries and the number of bottles in each delivery action to obtain the second type information and the second quantity information. Since each group only selects one representative image frame for image feature and recognition, the amount of data is greatly reduced and the data processing efficiency is improved. , reducing computing energy consumption; in addition, for the selection of representative image frames, by selecting a group of image frames for action path analysis of the delivery action, combined with the shooting range and angle set by the digital camera to determine the high-definition area of ​​the captured image, the action time point close to the center of the high-definition area is obtained to divide the shooting period of the same group of image frames into a time division ratio, and the time division ratio is used to select each group of representative image frames, thereby ensuring that the bottle delivered in the selected representative image frame is in the high-definition area of ​​the image, thereby improving the recognizability and recognition accuracy of the bottle; by preprocessing the representative image frames, noise interference can be eliminated and the recognition accuracy can be further improved.
