[0002] Due to the global pandemic, people are paying close attention to the effectiveness of disinfection in various places. In particular, since people travel by vehicle every day, the effectiveness of vehicle disinfection (such as buses and coaches) is receiving even more attention.

[0003] Existing methods for testing the effectiveness of vehicle disinfection generally involve disinfection personnel signing a disinfection log form for the corresponding date after disinfection. Inspectors then verify the signature and date on the log form to confirm effective disinfection. Alternatively, disinfection personnel may photograph the disinfected vehicle and send the photos to inspectors, who then judge the effectiveness of disinfection based on the disinfection marks in the photos. However, these existing methods are problematic. Firstly, falsified information on the disinfection log form and photos can lead to incorrect assessments of disinfection effectiveness by inspectors. Secondly, since vehicle inspections are typically conducted in batches, such as convoys, each inspection is resource-intensive and time-consuming. Summary of the Invention

BRIEF DESCRIPTION OF DRAWINGS

[0051] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the following will briefly introduce the drawings needed in the embodiments. It should be understood that the following drawings only show some embodiments of the present application, and therefore should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can also be obtained without creative labor on the basis of these drawings.

[0054] Figure 3A structural schematic diagram of an electronic device is shown. DETAILED DESCRIPTION

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application and are not all the embodiments. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, every other embodiment obtained by a person skilled in the art without creative work belongs to the scope of protection of the present application.

[0056] Before the present application is proposed, the existing method for detecting the disinfection effectiveness of a vehicle generally is that a disinfection personnel signs the corresponding date on a disinfection registration table after disinfection, and then a detection personnel confirms whether the disinfection personnel completes effective disinfection by checking the signature and date on the disinfection registration table, or the disinfection personnel takes a photo of the disinfected vehicle, and then sends the photo to the detection personnel, and the detection personnel judges whether the vehicle is effectively disinfected by the disinfection trace of the vehicle in the photo. However, the two methods in the prior art have the following problems: on the one hand, the information on the disinfection registration table is fake, and the photo is fake, which leads to the detection personnel making a wrong judgment on the disinfection effectiveness of the vehicle; on the other hand, since the detection of the vehicle is in the form of a vehicle fleet for batch detection, it is more time-consuming and labor-intensive to detect each time.

[0057] Based on this, the embodiments of the present application provide a method and device for detecting the disinfection effectiveness of a vehicle, an electronic device, and a medium, which can accurately detect the disinfection effectiveness of the vehicle and save manpower and resources.

[0058] It should be noted that before applying the disclosed method for detecting the disinfection effectiveness of a vehicle, the disinfection area provided in the target vehicle needs to be disinfected in advance. Here, the disinfection area is an area expected to be sprayed with disinfectant, for example, the disinfection area can be a door handle, a seat, etc.

[0059] Here, the disinfectant used in the disinfection is configured in advance, and the disinfectant contains a fluorescent agent configured to completely disappear after a preset period of time after the fluorescent agent is sprayed. Here, complete disappearance means that the area where the fluorescent agent remains will decrease, and the color will become lighter until it completely disappears. Preferably, the fluorescent agent is configured to completely disappear at the same time as the disinfectant, i.e., the disinfectant completely disappears after the preset period of time, and the fluorescent agent completely disappears after the preset period of time.

[0060] The fluorescent agent appears after being irradiated by the irradiation device. As an example, the irradiation device can be a purple light gun.

[0061] In order to facilitate the understanding of the embodiments of the present application, first, a system for detecting the effectiveness of vehicle disinfection disclosed in the exemplary embodiments of the present application will be described in detail.

[0062] The system for detecting the effectiveness of vehicle disinfection disclosed in the exemplary embodiments of the present application comprises: a recognition device arranged on a preset detection parking space, a device for detecting the effectiveness of vehicle disinfection, at least one irradiation device arranged in each target vehicle in the target vehicle fleet, and at least one camera device. As an example, the recognition device can be a license plate camera.

[0063] The recognition device is connected to the device for detecting the effectiveness of vehicle disinfection, the device for detecting the effectiveness of vehicle disinfection is connected to each irradiation device, and the device for detecting the effectiveness of vehicle disinfection is connected to each camera device.

[0064] Here, the target vehicle fleet can be a vehicle fleet currently managed and operated in a target transportation company. As an example, the target transportation company can be a long-distance passenger transportation company, or the target transportation company can be a bus operating company. When the target transportation company is a long-distance passenger transportation company, the target vehicle fleet is a long-distance bus fleet, and when the target transportation company is a bus operating company, the target vehicle fleet is a bus fleet. It should be noted that the target transportation company is not limited to the above-mentioned transportation companies, but can also be a transportation company of other passenger vehicles or a transportation company of cargo vehicles, and the present application does not make any limitation here.

[0065] Here, the preset detection parking space is a detection parking space where any target vehicle in the target vehicle fleet needs to be disinfected before starting from the starting location. For any target vehicle, only when the detection result of the target vehicle is effective disinfection, the target vehicle can start, otherwise, the target vehicle is disinfected again.

[0066] Next, a method for detecting the effectiveness of vehicle disinfection disclosed in the exemplary embodiments of the present application will be described in detail.

[0067] Please refer toFigure 1 , Figure 1 A flowchart of a method for detecting disinfection effectiveness of a vehicle is provided for an exemplary embodiment of the present application. As shown in the figure Figure 1 The method for detecting disinfection effectiveness of a vehicle provided by the embodiments of the present application includes the following steps:

[0068] S101, obtaining license plate information of any one target vehicle in a target vehicle fleet sent by an identification device arranged at a preset detection parking space.

[0069] Specifically, when the target vehicle arrives at the preset detection parking space, the identification device identifies the license plate of the target vehicle in response to any one target vehicle in the target vehicle fleet arriving at the preset detection parking space, obtains the license plate information of the target vehicle, and sends the license plate information to the central processor.

[0070] S102, determining at least one target irradiation device and at least one target camera device arranged in the target vehicle corresponding to the license plate information based on the license plate information.

[0071] As an example, a mapping relationship table indicating the correspondence between license plate information, irradiation devices, and camera devices can be previously set in the central processor, then the irradiation devices and camera devices corresponding to the license plate information are searched in the mapping relationship table, and the irradiation devices are determined as at least one target irradiation device arranged in the target vehicle corresponding to the license plate information, and the camera devices are determined as at least one target camera device arranged in the target vehicle corresponding to the license plate information.

[0072] S103, controlling the at least one target irradiation device to irradiate a plurality of disinfection areas previously arranged in the target vehicle for a preset irradiation duration.

[0073] Here, the preset irradiation duration is set according to actual needs, for example, the preset irradiation duration can be 10S.

[0074] When the target irradiation device irradiates the plurality of disinfection areas previously arranged in the target vehicle, the fluorescent agent in the disinfection areas will appear.

[0075] S104, controlling the at least one target camera device to capture the plurality of irradiated disinfection areas at a time point that is a preset duration away from the initial time point of irradiation by the target irradiation device, to obtain at least one initial fluorescent image; wherein each initial fluorescent image includes at least one disinfection area.

[0076] Here, the preset duration is less than the preset irradiation duration. For example, when the preset irradiation duration is 10S, the preset duration can be 3S.

[0077] Here, one target irradiation device can correspond to one disinfection area, or can correspond to multiple disinfection areas, and thus, one initial fluorescent image obtained by one target irradiation device after photographing a disinfection area can include only one disinfection area, or can include multiple disinfection areas.

[0078] S105, for each initial fluorescent image, identifying a disinfection area in the initial fluorescent image by using a first image processing technology.

[0079] Here, any image processing technology in the prior art can be used for processing, and as an example, for each initial fluorescent image, the initial fluorescent image is input into a pre-trained disinfection area identification model to identify a disinfection area in the initial fluorescent image.

[0080] Here, the disinfection area identification model can be trained by the following steps:

[0081] Obtaining multiple sample images; the sample images include different disinfection areas.

[0082] Training the disinfection area identification model by using the multiple sample images.

[0083] Here, as an example, the disinfection area can be an area defined by the coordinates of the upper left corner and the coordinates of the lower right corner of the disinfection area.

[0084] S106, for each disinfection area, identifying a fluorescent agent area in the disinfection area by using a second image processing technology;

[0085] Here, any image processing technology in the prior art can be used for processing, and as an example, the disinfection area and the picture of a standard disinfection area without fluorescent agent can be compared to identify the fluorescent agent area. It should be noted that the above way of identifying the fluorescent agent area is only to teach those skilled in the art how to implement, and the embodiments of the present application are not limited thereto, and the fluorescent agent area can also be identified by other ways.

[0086] If the fluorescent agent area is identified, then in step S107, for the disinfection area, the coverage of the fluorescent agent in the disinfection area is determined based on the disinfection area and the fluorescent agent area; the coverage is proportional to the size of the area of the fluorescent agent in the disinfection area at the current time;

[0087] As an example, this step can include step S1071, step S1072 and step S1073.

[0088] S1071, determining the area of the disinfection area.

[0089] As an example, the area of the disinfection area can be determined based on the length and width of the disinfection area in this step.

[0090] S1072, determine the area of the region constituted by the fluorescent agent region, and determine the area as the remaining area of the fluorescent agent.

[0091] As an example, the shape of the fluorescent agent region can be delineated by an algorithm in this step, and then the area of the region constituted by the fluorescent agent region is determined based on the shape. The algorithm can be written according to the actual situation.

[0092] S1073, determine the ratio of the remaining area to the area of the disinfection area as the coverage of the fluorescent agent in the disinfection area.

[0093] For example, the coverage C of the fluorescent agent in the disinfection area can be determined by the following formula:

[0094]

[0095] Wherein, P is the remaining area; I is the area of the disinfection area.

[0096] S108, based on the fluorescent agent region in the disinfection area, determine the volatility of the fluorescent agent in the disinfection area in the initial fluorescent image; the volatility is inversely proportional to the color depth of the fluorescent agent in the disinfection area at the current time;

[0097] As an example, this step can include step S1081, step S1082 and step S1083.

[0098] S1081, compare the fluorescent agent region in the disinfection area with a plurality of standard pictures preset to represent the volatility of the disinfection area at different time periods, and determine the color similarity of the disinfection area and each standard picture;

[0099] Here, the plurality of standard pictures are pictures with different fluorescent agent color depths, and each standard picture corresponds to a volatility. The deeper the fluorescent agent color, the smaller the volatility of the corresponding standard picture, and the lighter the fluorescent agent color, the greater the volatility of the corresponding standard picture.

[0100] S1082, if the color similarity is greater than a preset similarity, the corresponding standard picture is taken as a target standard picture. Here, the preset similarity is set according to the actual situation.

[0101] S1083, determine the volatility corresponding to the target standard picture as the volatility of the fluorescent agent in the disinfection area in the initial fluorescent image.

[0102] Please continue to refer to Figure 1At step S109, based on the coverage and volatility of the fluorescent agent in the disinfection area, the disinfection effectiveness of the disinfection area is determined.

[0103] As an example, the step can include step S1091, step S1092 and step S1093.

[0104] S1091, based on the coverage and volatility of the fluorescent agent in the disinfection area, the ratio of the coverage and volatility is determined.

[0105] For example, based on the coverage and volatility of the fluorescent agent in the disinfection area, the ratio of the coverage and volatility S can be determined by the following formula:

[0106]

[0107] S1092, when the ratio is greater than a preset ratio, the disinfection area is determined to be effective disinfection.

[0108] S1093, when the ratio is less than or equal to a preset ratio, the disinfection area is determined to be ineffective disinfection.

[0109] Here, since the fluorescent agent is configured to completely disappear after a preset period of time after the fluorescent agent is sprayed, the greater the coverage of the fluorescent agent, the shorter the time the fluorescent agent is sprayed and thus the greater the area remaining. Or the fluorescent agent is sprayed for a long time, but because the temperature is low on the day, the fluorescent agent does not significantly reduce the area remaining due to high temperature irradiation. Regardless of which of the above cases, since the fluorescent agent is configured to completely disappear at the same time as the disinfectant, when the coverage of the fluorescent agent is large, it can be said to some extent that the coverage of the disinfectant is also large, and when the coverage of the fluorescent agent is small, it can be said to some extent that the coverage of the disinfectant is also small.

[0110] In addition, the greater the volatility of the fluorescent agent, the longer the time the fluorescent agent is sprayed and thus the color has become lighter; or the fluorescent agent is sprayed for a short time, but because the temperature is high on the day, the fluorescent agent quickly lightens the color due to high temperature irradiation. Regardless of which of the above cases, since the fluorescent agent is configured to completely disappear at the same time as the disinfectant, when the volatility of the fluorescent agent is large, it can be said to some extent that the volatility of the disinfectant is also large, and when the volatility of the fluorescent agent is small, it can be said to some extent that the volatility of the disinfectant is also small.

[0111] Therefore, the greater the coverage of the fluorescent agent and the smaller the volatility, the better the current remaining state of the disinfectant. Therefore, when the ratio is greater than a preset ratio, the disinfection area is determined to be an effective disinfection area. When the ratio is less than or equal to a preset ratio, the disinfection area is determined to be an ineffective disinfection area.

[0112] S1010, determine the disinfection effectiveness of the target vehicle based on the disinfection effectiveness of each disinfection area.

[0113] As an example, in this step, the disinfection effectiveness of the target vehicle can be determined as effective disinfection when the number of effective disinfection areas is greater than the preset number, and the disinfection effectiveness of the target vehicle can be determined as ineffective disinfection when the number of effective disinfection areas is less than or equal to the preset number.

[0114] In addition, if the fluorescent agent area is not identified, it is determined in step S1011 that the disinfection effectiveness of the target vehicle is ineffective disinfection.

[0115] Here, if the fluorescent agent area is not identified, it means that the fluorescent agent has not remained in the disinfection area, i.e., the disinfectant has not remained; or the fluorescent agent has not been sprayed from the beginning, i.e., the disinfectant has not been sprayed from the beginning. At this time, the target vehicle needs to be disinfected again.

[0116] Further, after determining the disinfection effectiveness of the target vehicle, if the disinfection effectiveness of the target vehicle is effective disinfection, a prompt indicating that the vehicle can pass is issued.

[0117] If the disinfection effectiveness of the target vehicle is ineffective disinfection, a prompt indicating that the vehicle cannot pass is issued.

[0118] The exemplary embodiments of the present application provide a method for detecting the disinfection effectiveness of a vehicle, controlling the at least one target irradiation device to irradiate a plurality of disinfection areas pre-set in the target vehicle for a preset irradiation time, controlling the at least one target camera device to capture the plurality of disinfection areas after irradiation at a time point that is a preset time from an initial time point of irradiation by the target irradiation device, to obtain at least one initial fluorescent image, identifying, for each initial fluorescent image, a disinfection area in the initial fluorescent image, identifying, for each disinfection area, a fluorescent agent area in the disinfection area, then determining, for the disinfection area, the coverage rate and volatility of the fluorescent agent, and determining the disinfection effectiveness of the target vehicle based on the coverage rate and volatility of the fluorescent agent, so that the disinfection effectiveness of the vehicle can be accurately detected, and manpower and resources are saved.
