Description

Technical Field

[0001] The embodiments of the present invention relate to the field of environmental protection technology, and in particular to a method and device, medium, and terminal for monitoring the collection status of a garbage bin of a sanitation vehicle. Background Art

[0002] With the rapid development of the economy, the number of cities and their populations have increased significantly. As the scale and scope of cities continue to expand, the amount of urban domestic waste is also increasing. The collection of waste by sanitation vehicles is a key stage in waste disposal.

[0003] During the operation of sanitation vehicles, measuring the number of trash cans collected is a key parameter for evaluating the vehicle's workflow. Currently, at the site of garbage dumping operations, counting personnel manually record and tally the total number of effective dumping operations (essentially equivalent to the total number of trash cans used for effective dumping). Some methods use trash can weighing to measure the effective collection and weight of trash cans collected during a single operation. However, due to abnormalities in the actual garbage collection process, such as failed hanging bins and trash cans falling off, the accuracy of the collected trash can count is low. Manual recording is inefficient and labor-intensive. In summary, existing methods of counting the number of trash cans collected fail to strike a balance between accuracy and cost.

[0029] Compared with the prior art, the technical solution of the embodiment of the present invention has the following beneficial effects:

[0030] During the garbage dumping process, an operation signal for the garbage bin and the in-place status of the garbage bin during the garbage dumping process are obtained. The operation signal can at least determine the operation stage of the garbage bin during the garbage dumping process, and the operation stage at least includes the rising stage, the dumping stage, and the descending stage. Since the in-place status of the garbage bin can indicate whether the garbage bin is on the garbage bin carrying device, a first result can be obtained based on the in-place status of the garbage bin in each operation stage. The first result includes at least the dumping effectiveness of the garbage dumping. Determining the dumping effectiveness of the garbage dumping by the in-place status of the garbage bin in each operation stage can more realistically reflect the actual situation of the garbage bin on the garbage carrying device during the garbage dumping process and whether the actual dumping situation is normal. Therefore, updating the number of garbage bins collected based on the first result can improve the accuracy of the garbage bin number statistics. In addition, compared with manual recording methods, it saves costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] As mentioned above, manual recording is inefficient and labor-intensive. Weighing trash cans, on the other hand, allows for the effective collection of trash cans and the measurement of collected weights during a single operation. However, due to anomalies during actual collection, such as failed hanging bins or trash cans falling off, the accuracy of collected trash can counts is low. Therefore, existing methods for counting collected trash cans fail to achieve a balanced balance between accuracy and cost.

[0036] To address the above-mentioned issues, in an embodiment of the present invention, during the garbage dumping process, an operation signal for the garbage bin and the in-place status of the garbage bin during the garbage dumping process are obtained. The operation signal can at least determine the operation stage of the garbage bin during the garbage dumping process, and the operation stage can at least include the rising stage, the dumping stage, and the descending stage. Since the in-place status of the garbage bin can indicate whether the garbage bin is on the garbage bin carrying device, a first result can be obtained based on the in-place status of the garbage bin in each operation stage. The first result includes at least the dumping effectiveness of the garbage dumping. Determining the dumping effectiveness of the garbage dumping by the in-place status of the garbage bin in each operation stage can more realistically reflect the actual situation of the garbage bin on the garbage carrying device during the garbage dumping process and whether the actual dumping situation is normal. Therefore, updating the number of garbage bins collected based on the first result can improve the accuracy of the garbage bin collection statistics and save costs compared to manual recording methods.

[0037] In order to make the above-mentioned objects, features and beneficial effects of the embodiments of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] This application provides a method for monitoring the collection status of trash cans on a sanitation vehicle. This method can be used to count the number of trash cans collected by the sanitation vehicle during operation, thereby automatically counting the number of collected trash cans. The method can be executed by a terminal installed on the sanitation vehicle, a cloud platform, a cloud service, or a local device, and can be configured based on the specific application scenario.

[0039] In specific implementations, sanitation vehicles include wet garbage trucks, dry garbage trucks, food waste trucks, compressed garbage trucks, recyclable material transport trucks, etc. The sanitation vehicle is provided with a trash can dumping device (also known as a trash can lifting device), and the trash can dumping device includes a trash can carrying device. When dumping garbage, the trash can is mounted on the trash can carrying device, and the trash can carrying device drives the trash can to rise, flip, and lower, etc., so that the garbage in the trash can is dumped into the compartment of the sanitation vehicle. The compartment is usually equipped with a garbage dumping inlet, and the trash can carrying device is usually set at a corresponding position of the garbage can dumping inlet, such as below the garbage can dumping inlet or other suitable positions. In practice, the setting position of the trash can dumping device varies depending on the type of sanitation vehicle, and the specific setting position of the trash can dumping device is not limited here.

[0040] See also Figure 1 , a flowchart of a method for monitoring the state of a garbage bin collection bin of a sanitation vehicle according to an embodiment of the present invention is given, see Figure 1 The method for monitoring the status of a garbage bin collection includes the following steps:

[0041] Step 11: Obtain an operation signal for the trash can and the in-place status of the trash can during the garbage dumping process, wherein the operation signal is at least used to determine the operation stage of the trash can during the garbage dumping process, and the operation stage at least includes an ascending stage, a dumping stage, and a descending stage, and the in-place status of the trash can is used to characterize whether the trash can is on the trash can carrying device.

[0042] Step 12: obtaining a first result based on the status of the trash can in each operation stage, wherein the first result at least includes the effectiveness of the current trash dumping.

[0043] Step 13: Update the number of collection bins in the trash bin based at least on the first result.

[0044] As can be seen from the above, during the garbage dumping process, the operation signal for the garbage bin and the in-place status of the garbage bin during the garbage dumping process are obtained, and the operation signal can at least determine the operation stage of the garbage bin during the garbage dumping process, and the operation stage at least includes the rising stage, the dumping stage and the descending stage. Since the in-place status of the garbage bin can characterize whether the garbage bin is on the garbage bin carrying device, a first result can be obtained based on the in-place status of the garbage bin in each operation stage. The first result includes at least the dumping effectiveness of this garbage dumping. Determining the dumping effectiveness of the garbage dumping by the in-place status of the garbage bin in each operation stage can more realistically reflect the actual situation of the garbage bin on the garbage carrying device during the garbage dumping process and whether the actual dumping situation is normal, so that updating the number of garbage bins based on the first result can improve the accuracy of the garbage bin number statistics.

[0045] In a specific implementation, during the trash can emptying process, the trash can carrier can be controlled in response to an operation signal, thereby controlling the trash can on the carrier to empty. For example, the trash can carrier can be controlled to rise in response to an operation signal, thereby driving the trash can upward. After the trash can reaches a certain height, the trash can can be turned over in response to an operation signal. During the turning process, the bottom of the trash can can be higher than the opening of the trash can, and the trash in the trash can can be dumped out through one or more flips. After the trash is completely emptied, the trash can carrier can be controlled to descend in response to an operation signal, thereby driving the trash can downward.

[0046] The operation signal may include a lifting signal, a flipping signal, a lowering signal, etc. Among them, the lifting signal is used to control the trash can to rise. The flipping signal is used to control the trash can to flip. The lowering signal is used to control the trash can to lower.

[0047] The operational phases of a trash can during the dumping process include at least the raising phase, the dumping phase, and the lowering phase. The operational phase of a trash can can be determined in a variety of ways. For example, the phase between the raising signal and the flipping signal is the raising phase, the phase between the flipping signal and the lowering signal is the flipping phase, and the phase after the lowering signal is the lowering phase.

[0048] Furthermore, when acquiring the operation signal, the triggering time of the operation signal is acquired. Based on the triggering time of the operation signal, an operation time period corresponding to the operation phase can be determined, where the operation time period includes a start time and an end time.

[0049] Furthermore, the operational phases of the trash can during the garbage dumping process may also include the phase of pushing or moving the trash can into the effective area and the phase of mounting the trash can on the trash can carrier. The phase of pushing or moving the trash can into the effective area precedes the phase of mounting the trash can on the trash can carrier and precedes the ascending phase. After the descending phase, the operational phase may also include the phase of pushing the trash can out of the effective area.

[0050] It should be noted that in some cases, in a single garbage dumping operation, one or more of the above stages may actually be repeated, one or more of the above stages may not be experienced, or in addition to several of the above-listed stages, other stages may also be experienced.

[0051] In a typical application scenario, the operation signal includes at least a lift signal for controlling the trash can to rise. When the lift signal is detected, the presence detection function for the trash can is activated. After the presence detection function is activated, the presence status of the trash can can be collected, thereby saving resources.

[0052] In some embodiments, the presence of the trash can may be detected in a variety of ways.

[0053] For example, a pressure sensor is installed on a trash can carrier, and the pressure detected by the pressure sensor is used to determine whether the trash can is on the trash can carrier. When the value detected by the pressure sensor is greater than or equal to a set pressure threshold, the trash can is determined to be on the trash can carrier. Correspondingly, when the value detected by the pressure sensor is less than the set pressure threshold, it is determined that the trash can is not on the trash can carrier, that is, the trash can has fallen off the trash can carrier. The set pressure threshold is less than the weight of the empty trash can. The pressure sensor can be set on the trash can carrier and located at the bottom of the trash can. The pressure sensor can also be set on the rack in the trash can carrier for hanging the trash can.

[0054] For example, a distance sensor is installed on the trash can carrier to determine whether the trash can is on the trash can carrier by detecting the distance between the distance sensor and the trash can. When the detected distance is less than or equal to a set distance threshold, the trash can is determined to be on the trash can carrier. Correspondingly, when the detected distance is greater than the set distance threshold, the trash can is determined to be off the trash can carrier, i.e., it has fallen off the trash can carrier.

[0055] For another example, a trigger switch is provided on the hanger of the trash can carrying device. When the trash can is hung on the hanger, the signal fed back by the trigger switch can be used to determine whether the trash can is on the trash can carrying device.

[0056] Before step 11, the position of the sanitation vehicle may be located. When the sanitation vehicle is located to enter the working range, the collection of the operation signal for the garbage bin is started.

[0057] In a specific implementation, a positioning device may be installed on the sanitation vehicle. The positioning device may be a Global Positioning System (GPS) or a Beidou Navigation Satellite System (BDS, also known as COMPASS).

[0058] The operating range can be, for example, a pre-set garbage station or designated collection point. Each sanitation vehicle's corresponding operating range can be pre-configured and bound. For example, the vehicle's license plate can be bound to the corresponding operating range. This can further improve control accuracy, avoid false triggering of operation signals for garbage bins, prevent the collection of easily accessible information, improve the effectiveness of collected operation signals, and reduce energy consumption.

[0059] In practice, the working area range of the sanitation vehicle can be adjusted and updated to meet the work deployment needs of the sanitation vehicle.

[0060] In some embodiments, before starting to collect the operation signal for the trash can, the device for collecting the operation signal for the trash can may be in a dormant state, thereby saving energy consumption.

[0061] In some embodiments, the sanitation vehicle may be provided with operation buttons, such as an ascending operation button, a flipping operation button, and a descending operation button. When the operator triggers the ascending operation button, the trash can carrying device drives the trash can mounted thereon to ascend. When the operator triggers the flipping operation button, the trash can carrying device drives the trash can mounted thereon to flip over for garbage dumping. When the operator triggers the descending operation button, the trash can carrying device drives the trash can mounted thereon to descend. It is understandable that the operation signal is not limited to being triggered by the operation buttons provided on the sanitation vehicle. For sanitation vehicles with automatic dumping, the corresponding program can be pre-configured, and the operation signals corresponding to different stages can be configured in the program to detect the current operation stage of the trash can and generate the required operation signals based on the current operation stage.

[0062] In typical scenarios, the trash can carrier of some sanitation vehicles is usually stowed. The operator can press and hold the lowering signal to lower the carrier, preparing for the operator to place the trash can. When the operator presses and hold the lowering signal, the device collecting the trash can's operation signals enters the operating state. Once the device is in the operating state, it begins collecting operation signals.

[0063] In step 12, the effectiveness of the current garbage dumping is determined based on the status of the garbage bin in each operation phase, thereby obtaining a first result. The effectiveness of the current garbage dumping varies depending on the status of the garbage bin in each operation phase, as described in detail below.

[0064] In some embodiments, when the trash can suddenly changes from being on the trash can carrier to not being on the trash can carrier during the ascending stage, the dumping validity of this trash dumping is determined to be invalid, and the first result is obtained. At this time, the trash can falls off during the ascending stage.

[0065] Furthermore, for the scenario where the trash can falls off during the rising stage, the working status of this garbage dumping will be marked as abnormal.

[0066] In some embodiments, when the trash can is on the trash can carrier during both the ascending and dumping phases, and is not on the trash can carrier during the descending phase, the dumping validity of the current dumping is determined to be valid, and the first result is obtained. In this case, the trash can falls off during the descent phase.

[0067] Furthermore, for the scenario where the trash can falls off during the descent phase, the garbage dumping will be marked as abnormal in working status.

[0068] In some embodiments, when the trash can is in the position state of being on the trash can carrier during the ascending phase, the dumping phase, and the descending phase, the dumping validity of the current trash dumping is determined to be valid dumping, and the first result is obtained. In this case, it is a valid trash can hanging scenario.

[0069] Furthermore, for the scenario where the barrel is hung effectively, the garbage dumping will be marked as being in normal working condition.

[0070] In some embodiments, when the trash can is not on the trash can carrier during the ascending phase, the dumping phase, and the descending phase, the dumping validity of the current trash dumping is determined to be invalid, and the first result is obtained. In this case, the trash can is in an empty (no trash can) state.

[0071] Furthermore, for the empty (no bucket) scenario, the garbage dumping will be marked as normal working status.

[0072] In some embodiments, when the trash can's in-position state during the rising phase is on the trash can carrier, and its in-position state during the dumping phase suddenly changes from on the trash can carrier to not on the trash can carrier, the dumping validity of this trash dumping is determined to be valid pending, and the first result is obtained. In this case, the trash can falls off during the flipping phase. The in-position state during the dumping phase suddenly changes from on the trash can carrier to not on the trash can carrier, that is, the trash can falls off during the flipping process. At this time, the dumping status of the trash in the trash can is unknown. The trash may have been dumped completely, only a portion of the trash may have been dumped, or no trash may have been dumped at all. For cases where the dumping validity is valid pending, the amount of trash dumped can be further determined by other means.

[0073] Furthermore, for the scenario where the trash can falls off during the flipping stage, the garbage dumping will be marked as abnormal working status.

[0074] In some specific implementations of step 13, if the dumping validity in the first result indicates that the garbage dumping is valid, the number of the garbage bins is updated to increase by 1 based on the original number of the garbage bins.

[0075] In some other specific implementations of step 13, see Figure 2 , step 13 may specifically include the following steps:

[0076] Step 131: If the dumping validity in the first result indicates that the current garbage dumping is invalid or pending, a first dumping video of the current garbage dumping is obtained.

[0077] Step 132: perform identification analysis on the first dumping video to obtain a second result, which at least includes the dumping effectiveness of this garbage dumping.

[0078] Step 133: Update the number of collection bins in the trash bin based on at least the first result and the second result.

[0079] In a specific implementation of step 133, if the dumping validity in the first result and the second result are the same and both are invalid dumping, the number of bins in the trash can is updated to maintain the original number of bins. That is, when the dumping is invalid, the number of bins in the trash can remains the original number of bins.

[0080] In some embodiments, if the dumping validity in the first result is different from the dumping validity in the second result, the working status of this garbage dumping is marked as abnormal, that is, the working status label is marked as abnormal, and the information of the working status abnormality marking is at least included in the video information of the first dumping video.

[0081] Because the method of judging the effectiveness of garbage dumping based on the status of the garbage bin in each operational stage requires less computing power and energy consumption, and has higher accuracy, compared to relying on video recognition and analysis throughout the process, when the dumping effectiveness in the first result indicates that the garbage dumping was invalid or pending, a first dumping video of the garbage dumping is obtained, and the garbage dumping effectiveness is further judged based on the dumping effectiveness in the first result obtained based on the status of the garbage bin in each operational stage and the dumping effectiveness in the second result obtained based on the first dumping video. This can improve the accuracy of the garbage dumping effectiveness judgment while saving computing power and energy consumption.

[0082] Furthermore, the first video showing an abnormal working state can be output. For example, the first video showing an abnormal working state can be output to a designated location for manual review by back-end personnel. This allows back-end personnel to quickly locate the dumping video corresponding to the trash can that showed an abnormal working state during the dumping process, eliminating the need to screen each video one by one from a large amount of videos, thereby improving review efficiency.

[0083] In another specific implementation of step 133, if the dumping validity in the first result is different from the dumping validity in the second result, a second dumping video of this garbage dumping is obtained, and the first dumping video and the second dumping video are respectively captured by two different image acquisition devices, and the installation positions of the two image acquisition devices are different; the second dumping video is identified and analyzed to obtain a third result, and the third result at least includes the dumping validity of this garbage dumping; if the dumping validity in the third result is the same as the dumping validity of the first result or one of the second results, the number of collection bins of the garbage bin is updated based on the third result.

[0084] In some embodiments, the image capture device may be a camera. Two different image capture devices are installed at different locations on the sanitation vehicle to capture video of the trash can being emptied from different angles. At least one image capture device can capture the entire process of the trash can being emptied. The other image capture device can capture the entire process of the trash can being emptied, or can capture at least the final image of the dumping process.

[0085] When the sanitation vehicle can simultaneously empty two or more trash cans, the two image capture devices must be installed in positions that allow them to simultaneously capture the emptying videos of all the trash cans. It is understood that corresponding image capture devices can also be configured for trash cans placed in different positions to capture the emptying videos.

[0086] In some non-limiting embodiments, when two image capture devices are installed in positions sufficient to simultaneously capture videos of all trash cans being dumped, one image capture device can be configured as a primary image capture device and the other as a secondary image capture device. The video captured by the primary image capture device serves as the first dumping video, and the video captured by the secondary image capture device serves as the second dumping video.

[0087] When the main image acquisition device fails, the auxiliary image acquisition device is switched to the main image acquisition device.

[0088] In some embodiments, the first dumping video begins to be collected when a lifting signal is detected and the trash can in-place status indicates that the trash can is on the trash can carrying device. The first dumping video ends its collection after a lowering signal is detected and the trash can in-place status indicates that the trash can has left the trash can carrying device. In this way, the first dumping video that can be collected can contain key information in the garbage dumping process (information on the rising stage and / or the falling stage), meeting the needs of counting the number of trash cans in garbage dumping without recording too much redundant information, reducing the size of the first dumping video, and reducing the computing power required for recognition and analysis, thereby improving recognition and analysis efficiency.

[0089] In some embodiments, after dumping, the worker drags the trash can off the trash can support device (such as a rack). The trash can's in-place state indicates that the trash can has been detached from the trash can support device, completing the first dumping video acquisition process. A complete first dumping video and its video information are generated, and other information is recorded, such as one or more of the following: the work location, the number of bins per trip, the time information, and the work status. The work location, the number of bins per trip, the time information, and the work status can be stored separately or included with the video information of the first dumping video. The data storage and transmission module transmits and stores the first dumping video, its video information, and other information, completing a single garbage dumping cycle.

[0090] In some embodiments, the operation time of the operation signal for the trash can is obtained, and the operation time is used as the video information of the first dumping video. The video information can be displayed in the form of a timeline, and the operation signal is marked at the corresponding time position on the timeline. When the first dumping video is played, the timeline can be displayed. For example, the raising signal of the trash can is marked at time point A on the timeline, the flipping signal is marked at time point B, and the lowering signal is marked at time point C. This makes it easier for backstage personnel to quickly locate the various dumping stages of the trash can dumping process.

[0091] The video information of the first dumping video also includes: location information and / or working status information, wherein the working status information is used to indicate whether each operation node in the entire garbage dumping process is normal. When an abnormality occurs in the dumping process, it can be determined that the working status information is abnormal.

[0092] Reference Figure 3 In the specific implementation of step 132, step 132 specifically includes the following steps:

[0093] Step 1321 , performing target detection on each frame image in the first dumping video to obtain detection information of a target object, where the target object is a designated part of the trash can.

[0094] In a specific implementation, a YOLO model can be used to detect targets in each frame of the first dumping video. After training, the YOLO model outputs the image in the ONNX format. It is understandable that other image processing models can also be used for target detection, and examples are not given here one by one.

[0095] In some embodiments, the target object detection information includes at least the target object's category, area, center, and dimensions. The target object's center can be represented by center coordinates, and the target object's dimensions can include its width and height. The target object can be a trash can's opening, body, lid, or wheels. The target object category can include the opening, body, lid, or wheels.

[0096] Based on the type of garbage in the garbage bin and / or the current time, the confidence of each category of target objects in target detection is determined; based on the confidence of each category of target objects, target detection is performed on each frame image to obtain detection information of the target object.

[0097] For example, the type corresponding to the target object with the highest confidence is used as the category of the target object.

[0098] The quality of the first dumping video may be affected by various factors, such as weather and garbage type. For example, videos collected during the day are generally of better quality, while videos collected at night or in inclement weather (fog, haze, etc.) are of relatively poor quality. For the same type of target object, different confidence levels can be configured for daytime, nighttime, and inclement weather. The daytime confidence level can be higher than the confidence levels corresponding to nighttime and inclement weather to improve the accuracy of target object recognition. Relatively low confidence levels are configured for nighttime and inclement weather to facilitate target object recognition and reduce the probability of non-recognition. Furthermore, for sanitation vehicles transporting wet garbage, the target object confidence level can be lowered to facilitate recognition and reduce the probability of non-recognition.

[0099] In some non-limiting embodiments, before performing target detection on each frame of the first dumping video, data preprocessing may be performed on each frame of the first dumping video. The data preprocessing may include operations such as noise removal, contrast adjustment, brightness adjustment, and image normalization.

[0100] For example, the image initialization module is configured with one or more data preprocessing operations, such as noise removal, contrast adjustment, brightness adjustment, and image normalization. Each frame of the first dumped video is passed through the image initialization module for data preprocessing, resulting in a processed, normalized image. This data preprocessing can reduce the impact of noise, contrast, brightness, and other factors on image recognition and analysis results, thereby improving the accuracy of image recognition and analysis.

[0101] Step 1322 : Track the target object and determine the operation stage of the trash can according to changes in the detection information of the target object during the target tracking process.

[0102] In a specific implementation of step 1322, during the target tracking process, the center position change information of the target object and the size change information of the target object are obtained based on the detection information of the target object; the corresponding operation stage determination rule is obtained according to the category of the target object; and based on the obtained operation stage determination rule, the center position change information of the target object and the size change information of the target object, the operation stage of the trash can is determined.

[0103] The operation phase determination rules include an ascending phase determination rule and a descending phase determination rule.

[0104] The ascending stage determination rule includes: the center position continues to rise and the size of the target object continues to increase. If the center position change information of the target object meets the requirement of the center position continues to rise and the size change information of the target object meets the requirement of the size of the target object continues to increase, then the trash can is determined to be in the ascending stage.

[0105] The descending stage determination rule includes: the center position continues to descend and the size of the target object continues to decrease. If the center position change information of the target object meets the requirement of the center position continuing to descend and the size change information of the target object meets the requirement of the size of the target object continuing to decrease, then the trash can is determined to be in the descending stage.

[0106] Step 1323: Count the number of trash bins in each operation phase and obtain the second result.

[0107] In some embodiments, the number of first collection bins of the trash can appearing in the ascending phase is counted; and the number of second collection bins of the trash can appearing in the descending phase is counted.

[0108] If the first number of buckets is greater than the second number of buckets, it is determined that a bucket dropped during the descent phase of the trash can, and the second number of buckets is updated to be the same as the first number of buckets, obtaining a second result. In the second result, the effectiveness of this garbage dumping is considered to be effective dumping. Since the bucket dropped at the extreme end of the descent, the garbage dumping has already been completed at this point, so the effectiveness of the garbage dumping is determined to be effective dumping. In this way, it is possible to avoid missing statistics on the number of buckets collected by the trash can, further improving the accuracy of the statistics on the number of buckets collected by the trash can. The second number of buckets can be updated to be the same as the first number of buckets when the trash can rises next time, or it can be updated after the second result is obtained.

[0109] If the first number of collection bins is less than the second number of collection bins, the second result is obtained, and the effectiveness of this garbage dumping in the second result is effective dumping. In the case of bad weather such as night, fog and haze, or the garbage in the garbage bin is affected by the garbage in the garbage bin, which causes the garbage bin to be successfully identified during the rising stage, but the garbage bin is identified after the garbage in the garbage bin is dumped, even if the first number of collection bins is less than the second number of collection bins, the effectiveness of this garbage dumping is considered to be effective dumping, which can avoid missing statistics on the number of garbage bins and further improve the statistical accuracy of the number of garbage bins. Furthermore, the first number of collection bins can be updated to be the same as the second number of collection bins.

[0110] If the first number of bins is equal to the second number of bins, and both indicate no trash can is present, the second result indicates that the effectiveness of this trash dump is invalid. In this case, no trash can was identified during either the ascending or descending phases, so the effectiveness of this trash dump is invalid.

[0111] When counting the number of first collection bins in the rising phase of the trash can, after determining that the trash can is in the rising phase, the number of first collection bins in the rising phase is counted. If the trash can is determined to be in the rising phase multiple times, counting of the trash can in the rising phase is terminated. If a trash can falls off the trash can carrier and is remounted on the trash can carrier for continued dumping, the above counting method can be used to avoid duplicate counting of the trash can, thereby improving the accuracy of the number of collection bins.

[0112] In some non-limiting embodiments, if the category of the target object identified during the descent phase is the body of the trash can or the mouth of the trash can, the effectiveness of this garbage dumping is determined to be effective dumping.

[0113] Before step 1322, it is determined that the target object is within the valid area based on the area of ​​the target object. In this way, interference from other objects (such as boxes and trash cans passing by) can be avoided.
