[0026] It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions.

Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0027] Example 1

[0028] like Figure 1-2 This is a schematic diagram of the structure of the present invention. The trash cans are connected to the control center of the intermodal platform system via a 4G network. Cameras and wireless internet access systems are installed at the trash can stations, and the wireless internet access system communicates with the intermodal platform system via the network. Each trash station is equipped with a location identification code. The electronic image of the location identification is displayed in the intermodal platform system. The status information of the trash can location is transmitted via network information via a flag bit.

[0029] When the automatic bucket changing system receives the garbage bin information containing location information and status information sent by the location information, it obtains the location information of the sweeper, that is, the garbage collection device, and plans the path navigation information of the sweeper for executing the bucket changing through the location information of the garbage bin and the sweeper.

[0030] The overflow detection method of the trash can is to perform weight and graphic detection in the display of trash placement. Standardized load-bearing values and capacity values are set for different trash can specifications. The load-bearing value of the trash can can be detected by a weighing sensor or a deformation sensor.

[0031] like Figure 3 As shown, in this application, a unified camera is installed at a garbage station, i.e., an environmental protection house, to first perform edge detection on the image of the garbage bin. The camera position can be fixed or adaptively adjusted. Standard graphical frame features are extracted. When the shape extracted from the edge features of the garbage bin does not exceed the boundary, the possibility of overflowing of the garbage bin is determined. A secondary determination of whether overflow is possible is then made based on a threshold value for the weight of the garbage bin. The matching feature extracts feature information at a fixed location, which is obtained through image processing matching overlap, reducing the amount of computation required.

[0032] The trash can may be provided with a panel control which implements an overflow indication signal for controlling a satisfactory state.

[0033] The trash can can also include a door opening motor, an IC card reader, a QR code scanner and a human body sensor, and a travel switch is provided for opening the box body in the trash can. The travel switch is used to record the opening data information of the cabinet door.

[0034] Optionally, while detecting the edge features of the waste bin, edge detection can be performed on the image of the waste bin to extract the shapes of the waste items in the image, thereby assisting in determining whether the bin is likely to be overflowing. The characteristic of false overflowing can be that the waste bin is supported by a rod, resulting in abnormal edge detection of the waste bin.

[0035] Exemplarily, the RGB image is grayscaled and binarized to obtain a binary image; the binary image is subjected to noise filtering and morphological processing in sequence to obtain a preprocessed image; wherein, median filtering is selected for noise filtering to remove noise so that the image contour maintains good clarity; according to the opening operation set in the morphological processing, impurities outside the contour of the garbage bin are removed, and the pores within the contour of the garbage pile are filled to prepare the image for preprocessing by the subsequent edge detection system.

[0036] After obtaining the preprocessed image, the control center performs garbage overflow detection on the preprocessed image to obtain an area image of the garbage bin with an external matrix marking the garbage bin; the preprocessed image is subjected to garbage pile detection to obtain an edge image of the garbage pile area with a minimum external matrix marking the garbage pile.

[0037] The edge detection process uses the Canny operator to obtain a clear edge image. For edge images that extend beyond the standard image area, i.e., the location information of protruding garbage piles, the minimum circumscribed matrix method is used to detect the garbage pile area in the edge image, obtaining an edge image of the garbage pile area marked with a minimum circumscribed matrix. This minimum circumscribed matrix size and location information is used for subsequent image cropping. If the edge feature information in the area does not contain irregular line segment overflow information, and the weight information is below the standard value, it is judged as a false alarm, indicating false overflow.

[0038] Optionally, the edge image detection and comparison may include extracting feature information from the first edge detection image and the second edge detection image, where the feature information is preferably line information obtained through edge detection. Specifically, the first edge detection image and the second edge detection image are compared and matched for similarities and differences, and feature information that matches or partially matches between the two images is selected as feature information of the characteristic portion; the feature information is information in the same location area. Optionally, rotational symmetry operations may be performed on the edge detection image information.

[0039] The feature information in the second edge detection image may be standard image information or different edge detection images at a preset time interval. The user can obtain abnormal features of different trash bins through the frame information in the image to determine whether the trash bin is full.

[0040] Exemplarily, and preferably, the line segments are filtered based on the line segment set in the first edge detection image to remove interfering line segments. Interfering line segments are line segments of non-target objects (i.e., non-trash can areas), such as line segments of trash in a trash can, background line segments of the target object's surroundings, etc. After removing the interfering line segments, the line segments of the target object are retained in the candidate line segment set and their position information is recorded.

[0041] In a preferred embodiment, the length distribution of line segments can be calculated during line segment filtering. The lengths of all identified line segments are counted and arranged in descending order of length. Overflow can be determined by the number of long line segments. For example, the length and width of a standard trash can have fixed edge values. When overflowing, due to the presence of garbage, the detection results in a variety of line segment feature information of varying lengths.

[0042] Preferably, a filtering threshold can be selected based on the frequency of line segment lengths. Line segments are filtered based on the selected filtering threshold. The filtering threshold can be set to line length, and line segments with lengths less than the filtering threshold can be removed based on the filtering threshold.

[0043] For example, we can remove the garbage line segments in the trash can and retain the line segments that are greater than or equal to the filtering threshold, such as the line segment at the top edge of the trash can mouth. We also set the line segments for the garbage outlet. The line segments in the candidate line segment set remove some interfering line segments, reducing the amount of subsequent data calculations.

[0044] Preferably, statistics can be performed in the form of a distribution graph, and a filtering threshold can be selected based on the line length distribution. The filtering threshold can be selected based on the length of the line segment (which can be the longest line segment, the shortest line segment, the median line, the average line segment, or the quartile).

[0045] Example 2

[0046] Based on the solution of Example 1, in the overflow detection of the garbage bin, the control center obtains data information of the travel detection switch when the garbage bin is opened. When no return information is set after the travel switch information is turned on, the acquisition of image frame information of the corresponding garbage bin is triggered.

[0047] After obtaining the preprocessed image, the control center performs garbage overflow detection on the preprocessed image to obtain an area image of the garbage bin with an external matrix marking the garbage bin; the preprocessed image is subjected to garbage pile detection to obtain an edge image of the garbage pile area with a minimum external matrix marking the garbage pile.

[0048] The edge detection process uses the Canny operator to obtain a clear edge image. For edge images that extend beyond the standard image area, i.e., for location information of protruding garbage piles, the minimum circumscribed matrix method is used to detect the garbage pile area in the edge image, obtaining an edge image of the garbage pile area marked with a minimum circumscribed matrix. This minimum circumscribed matrix size and location information is used for subsequent image cropping. If the edge feature information in the area does not contain irregular line segment overflow information and the weight information is below the standard value, a false alarm is determined as false overflow.
