Abstract
Description
Technical Field
[0001] The present invention relates to a technique for determining whether a safety cabinet used, for example, in the field of regenerative medicine has been reliably wiped and disinfected, and visualizing the result of the determination.
Background Art
[0002] It is extremely important to reliably wipe and disinfect safety cabinets used in fields such as regenerative medicine. For this reason, a manual (guide) for wiping and disinfection work is prepared, and workers performing wiping and disinfection carry out the work in accordance with the manual.
[0003] However, a method for proving that wiping and disinfection have been completed reliably has not yet been established. In the field of regenerative medicine, since prevention of contamination is essential, the practice is to refrain from using the safety cabinet during the period required for cell death, resulting in poor utilization efficiency of the safety cabinet.
[0004] As a conventional technique for determining a disinfected area within a surface area, there is a technique disclosed in Patent Document 1 (International Publication WO2022 / 080352). If the technique for extracting a cold trace area disclosed in Patent Document 1 is used, by using a thermal camera and a substantial object camera (for example, a visible light camera) to acquire the temperature drop due to the heat of vaporization on the surface of an object sprayed with disinfectant, the area sprayed with disinfectant within the surface area can be extracted as a cold trace area.

Summary of the Invention
Problem to be Solved by the Invention
[0006] As described above, the technology disclosed in Patent Document 1 makes it possible to extract the area of the surface that has been exposed to disinfectant as a cold trace area.
[0007] However, if the surface area is composed of a surface that easily reflects far-infrared light, such as a stainless steel surface, it is difficult to obtain the temperature of the surface area using the technology disclosed in Patent Document 1. In other words, with the technology disclosed in Patent Document 1, when targeting surfaces such as stainless steel surfaces, it is difficult to determine the areas within the surface area that have been successfully disinfected, and as a result, it is difficult to determine the areas within the surface area that have been successfully wiped and disinfected.
[0008] This invention has been made in view of the above points, and aims to provide a technology that makes it possible to determine the area of a surface that has been successfully cleaned and disinfected, even when the target surface is a stainless steel surface or the like. [Means for solving the problem]
[0009] According to the disclosed technology, a first determination unit performs a first determination process which determines a first area within a range to be wiped and disinfected, which is composed of surfaces included in a certain space, to which disinfectant solution has been applied in amounts exceeding a predetermined first standard. A second determination unit determines that an area within the first region where pressure greater than or equal to a predetermined second criterion has been applied after the first determination is an area where wiping and disinfection was successful, A cleaning and disinfection determination device is provided, which includes a wipe-and-determination device. [Effects of the Invention]
[0010] According to the disclosed technology, even when targeting surfaces such as stainless steel surfaces, it is possible to determine the areas within the surface area that have been successfully cleaned and disinfected. [Brief explanation of the drawing]

[0012] Hereinafter, embodiments of the present invention (the present embodiment) will be described with reference to the drawings. The embodiments described below are merely examples, and the embodiments to which the present invention is applied are not limited to the following embodiments.
[0013] Hereinafter, the problem will first be described in more detail, and then the technology according to the present embodiment will be described.
[0014] (Problem) Fig. 1 shows an overview of a working chamber of a safety cabinet. The working chamber of the safety cabinet is formed of a stainless steel surface. The stainless steel surface reflects light in the far-infrared region. Therefore, when a safety cabinet is photographed by a thermal camera, the temperature of surrounding objects and air reflected by the stainless steel surface is captured, and the temperature of the stainless steel surface itself can hardly be obtained. Fig. 2 shows an image obtained by photographing the safety cabinet with the thermal camera.
[0015] Therefore, when the target is a stainless steel surface such as the working chamber of a safety cabinet, even if the technique of extracting cold trace regions described in Patent Document 1 is used, there is a problem that it is difficult to determine a successfully disinfected region in the surface region. That is, there is a problem that it is difficult to determine a successfully wiped and disinfected region in the surface region.
[0016] Hereinafter, the technology according to the present embodiment for solving the above problem will be described in detail. Specifically, the outline of the embodiments and the first to sixth embodiments will be described.
[0017] (Summary of the embodiment) The wiping and disinfecting process is carried out by applying disinfectant solution and then wiping it off. In this embodiment, the wiping and disinfecting determination device, described later, determines that areas within the area to be wiped and disinfected have been reliably wiped and disinfected if sufficient pressure has been applied after the disinfectant solution has been sufficiently applied. The wiping and disinfecting determination device displays the results of this determination, making it possible to visualize whether or not each area within the target area has been wiped and disinfected.
[0018] The disinfection determination device determines whether the disinfectant solution has been sufficiently applied by, for example, whether the temperature of the target area has dropped sufficiently after the liquid has been applied compared to before.
[0019] The wiping and disinfection determination device determines whether sufficient pressure has been applied, for example, by checking whether the pressure detected by a pressure sensor is sufficient. For this purpose, a pressure sensor is installed, for example, on the wiping part of the tool used for wiping. Furthermore, to make it easier to identify the wiping area from the image captured by the camera inside the safety cabinet, for example, a marker is colored on that area.
[0020] The technology according to this embodiment will be described in more detail below using the first to sixth embodiments.
[0021] (First Embodiment) First, the first embodiment will be described. The cleaning and disinfection of safety cabinets and the like is performed by an operator first applying disinfectant solution to the area to be cleaned and disinfected, and then wiping it with force. In order to successfully disinfect, the operator must apply a sufficient amount of disinfectant solution to remove, kill, and neutralize harmful microorganisms and cells. In addition, in order to successfully wipe, the operator must apply sufficient pressure when wiping to remove dirt.
[0022] Therefore, in this embodiment, within the area to be wiped and disinfected, the area where the disinfectant solution is sufficiently applied during the application process and sufficient pressure is applied during the wiping process is determined to be an area where the wiping and disinfection was successful. Hereafter, the area where the wiping and disinfection was successful may be referred to as the successful wiping and disinfection area.
[0023] In the first embodiment, one form of a wiping and disinfection determination device 100 is described, which determines that an area within the area to be wiped and disinfected is a successful wiping and disinfection area if the disinfectant solution is sufficiently applied during the application of the disinfectant solution and sufficient pressure is applied during the wiping process.
[0024] [Wipe-and-disinfectant determination system 10 and wipe-and-disinfectant determination device 100] Figure 3 is a diagram showing an example of the functional configuration of the wipe-and-disinfectant determination system 10 in the first embodiment. As shown in Figure 3, the wipe-and-disinfectant determination system 10 of the first embodiment includes a wipe-and-disinfectant determination device 100, a thermal camera 200, a physical object camera 300, a wiping tool 400, a display device 500, and an input device 600. The "liquid spray determination device 700" shown in Figure 3 will be described later.
[0025] As shown in Figure 3, the first embodiment of the wipe-and-disinfect determination device 100 includes a thermal image acquisition unit 110, an object image acquisition unit 120, a pressure acquisition unit 130, a first determination unit 150, and a second determination unit 160. Each of these units is realized, for example, by causing the CPU to execute one or more programs installed on a computer.
[0026] The cleaning and disinfection determination device 100 is connected to a thermal camera 200 and a physical camera 300 so that it can receive images from the thermal camera 200 and the physical camera 300. The thermal camera 200 and the physical camera 300 are installed so that they can photograph the area to be cleaned and disinfected.
[0027] In other words, the first embodiment assumes that the imaging area of the thermal camera 200 and the imaging area of the physical object camera 300 coincide or can be associated with each other. If the imaging areas of the thermal camera 200 and the physical object camera 300 do not coincide, it is sufficient to perform calibration in advance so that the correspondence between the thermal image obtained by the thermal camera 200 and the physical object image obtained by the physical object camera 300 can be determined.
[0028] Furthermore, if the work surface of the safety cabinet is to be wiped and disinfected, the thermal image acquisition unit 110 and the physical object image acquisition unit 120 may each perform affine transformations on the thermal image obtained by the thermal camera 200 and the physical object image obtained by the physical object camera 300, respectively, to obtain thermal and physical images in which the correspondence between the work surface can be understood.
[0029] Furthermore, as shown in Figure 3, the wiping tool 400 is connected to the wiping disinfection determination device 100 so that it can receive pressure information from the wiping tool 400. In addition, as shown in Figure 3, the display device 500 is connected to the wiping disinfection determination device 100 so that it can output the determination result obtained by the wiping disinfection determination device 100 to the display device 500. Furthermore, as shown in Figure 3, the input device 600 is connected to the wiping disinfection determination device 100 so that it can receive information from the input device 600.
[0030] In the following, we will first describe in detail each part of the wipe-and-disinfectant determination system 10, excluding the wipe-and-disinfectant determination device 100, and then describe in detail the wipe-and-disinfectant determination device 100.
[0031] [Stereo Camera 300] The object camera 300 is a camera for photographing physical objects. The object camera 300 captures an image of physical objects within a certain shooting range, more specifically, an object image which is an image composed of the images of physical objects present within that shooting range as seen from the object camera 300. The object image captured by the object camera 300 is input to the object image acquisition unit 120.
[0032] An example of a physical object camera 300 is a visible light camera, which can capture electromagnetic waves in the wavelength range of 400 nm to 780 nm. In this case, the physical object image may also be called a visible image.
[0033] Another example of the physical object camera 300 is a camera capable of capturing electromagnetic waves in the near-infrared wavelength range, for example, from 800 nm to 1000 nm. If the wavelength range of electromagnetic waves present in the shooting range due to illumination or the like is not included in the wavelength range of electromagnetic waves obtained by the physical object camera 300, the cleaning and disinfection judgment system 10 may be equipped with an irradiator (not shown) that emits electromagnetic waves in the wavelength range obtained by the physical object camera 300, thereby irradiating the shooting range with electromagnetic waves in the wavelength range obtained by the physical object camera 300.
[0034] A physical object is something that has a physical form. If the work surface of a safety cabinet is the area to be wiped and disinfected, then the imaging range is the work surface of the safety cabinet which is the area to be wiped and disinfected, and an example of a physical object present in the imaging range is the wiping tool 400.
[0035] [Thermal Camera 200] The thermal camera 200 captures images of heat emitted by physical objects within the same shooting range as the physical object camera 300, or more specifically, thermal images composed of images acquired from the thermal camera 200 of heat radiated by physical objects within that shooting range. The thermal images captured by the thermal camera 200 are input to the thermal image acquisition unit 110.
[0036] The Thermal Camera 200 is a camera that captures thermal radiation (far-infrared region), and can capture electromagnetic waves in the range of 8 μm to 14 μm, for example.
[0037] If the work surface of the safety cabinet is to be wiped and disinfected, then the area to be photographed is the work surface of the safety cabinet that is to be wiped and disinfected.
[0038] [Cleaning tool 400] The cleaning tool 400 is used to perform cleaning work on the surface to be cleaned. For example, when cleaning and disinfecting the work surface of a safety cabinet, the surface to be cleaned, which is the area to be cleaned and disinfected, is the work surface of the safety cabinet, which is the surface to be wiped, and the cleaning work is wiping.
[0039] Figure 4 shows an example of the configuration of the cleaning tool 400. Figure 4(a) is a side view of the cleaning tool 400, and Figure 4(b) is a top view of the cleaning tool 400. As shown in Figure 4(b), the cleaning tool 400 in this example is rectangular when viewed from above. The cleaning surface 5 and hard surface 3, which will be described later, are also rectangular when viewed from above. Figure 4(a) is a view from the long side of the rectangle. However, the configuration is the same as in Figure 4(a) when viewed from the short side of the rectangle.
[0040] As shown in Figure 4, the cleaning tool 400 consists of a cleaning component 7 and a gripping component 1. The gripping component 1 is a component for the operator to grip in order to perform the cleaning operation with the cleaning component 7. The cleaning component 7 is a component that includes a cleaning surface 5 and a hard surface 3 that supports the cleaning surface 5 and transmits the force applied by the operator to the cleaning surface 5 using the gripping component 1.
[0041] In the following explanation, the embodiments are described assuming a human operator, but a human operator is merely one example. For instance, instead of a person holding the cleaning tool, the cleaning tool could be attached to a robot or control device to perform disinfection.
[0042] Furthermore, if the cleaning tool 400 is used for cleaning the work surface of a safety cabinet, the cleaning tool 400 may be called a wiping tool, the cleaning component 7 may be called a wiping component, and the cleaning surface 5 may be called a wiping surface. Alternatively, the cleaning tool 400 may be called a cleaning tool, the cleaning component 7 may be called a cleaning component, and the cleaning surface 5 may be called a cleaning surface.
[0043] The cleaning tool 400 is equipped with a pressure sensor 4 that detects the pressure applied to the surface to be cleaned by the operator performing the cleaning work using the cleaning tool 400. The pressure sensor 4 detects the pressure applied to the surface to be cleaned by the operator performing the cleaning work via the cleaning tool 400, and may be provided between the cleaning surface 5 and the hard surface 3 as illustrated in Figure 4, or at the joint portion 6 between the cleaning component 7 and the gripping component 1, or at another part of the cleaning tool 400.
[0044] Furthermore, it is preferable that at least one of the operator-side and cleaning surface-side sides of the pressure sensor 4 be fitted with a material that has a certain degree of flexibility. If the pressure sensor 4 is fitted between the cleaning surface 5 and the hard surface 3, for example, it is preferable that a flexible material be fitted between the hard surface 3 and the pressure sensor 4.
[0045] The pressure information detected by the pressure sensor 4 is input to the pressure acquisition unit 130. For this purpose, the cleaning tool 400 is also equipped with output wiring 2 that outputs the pressure information detected by the pressure sensor 4 to the pressure acquisition unit 130.
[0046] In the example shown in Figure 4(a), the "wiping surface 5" may be a plate-shaped member of a certain thickness that has a surface that contacts the surface to be wiped during wiping. This member may be made of the "flexible material" described above. Furthermore, the "surface that contacts the surface to be wiped during wiping" may be called the wiping surface, and the plate-shaped member having this wiping surface may be provided on the lower side of the pressure sensor 4 shown in Figure 4(a).
[0047] The pressure sensor 4 in the example shown in Figure 4(a) may be, for example, a sheet, or consist of one or more pads, or may be something other than these.
[0048] In the example shown in Figure 4(a), the "hard surface 3" may be a plate-shaped member of a certain thickness that has a surface in contact with the pressure sensor 4 (or a flexible material). Alternatively, the "surface in contact with the pressure sensor 4 (or a flexible material)" may be called the hard surface, and the plate-shaped member having this hard surface may be provided on the upper side of the pressure sensor 4 shown in Figure 4(a).
[0049] In this embodiment, a pressure sensor is used as an example of a device for measuring pressure, but the device for measuring pressure is not limited to a pressure sensor. For example, pressure may be measured using a proximity sensor, an optical sensor, or a conductive cloth sensor.
[0050] [Display device 500] The display device 500 is a general-purpose device that displays the input image, such as a so-called liquid crystal display or a tablet terminal. When the cleaning and disinfection determination device 100 obtains and outputs a determination result image, the display device 500 receives the determination result image as input and displays the determination result image.
[0051] If the work surface of the safety cabinet is to be wiped and disinfected, for example, the judgment result image is an image of the work surface of the safety cabinet viewed from the front (usually from above), and is an image that allows for the visual distinction between the area that the wiped and disinfected determination device 100 determined to be a successful area and the area that the wiped and disinfected determination device 100 did not determine to be a successful area (hereinafter also referred to as the "unsuccessful area of wiped and disinfected").
[0052] [Input device 600] The input device 600 is a general-purpose device that accepts input operations from the user, such as a mouse or keyboard. When the input device 600 accepts an input operation from the user, it outputs information corresponding to that input operation to the cleaning and disinfection determination device 100. In other words, the information output by the input device 600 is input to the cleaning and disinfection determination device 100.
[0053] [Wipe-and-disinfectant detection device 100] In the wiping and disinfection determination device 100, first, the first determination unit 150 determines, by the first determination described below, the area within the imaging range, which includes the area to be wiped and disinfected, where the disinfectant solution was sufficiently applied during the application of the disinfectant solution (hereinafter also referred to as the "first area"). Furthermore, the second determination unit 160 determines, by the second determination described below, that the area within the first area where sufficient pressure was applied during the wiping operation is the area where wiping and disinfection was successful. The first and second determinations will be explained in detail below.
[0054] <First Judgment> As mentioned above, when photographing a safety cabinet with the thermal camera 200, as shown in Figure 2, the camera captures the temperature of the surrounding objects and air reflected from the stainless steel surface, and it is almost impossible to obtain the temperature of the stainless steel surface itself.
[0055] On the other hand, once the disinfectant is applied, it is possible to capture the temperature of the disinfectant with the thermal camera 200 until the disinfectant evaporates. Therefore, the first determination unit 150 in the first embodiment of the wiping disinfection determination device 100 uses the thermal image captured by the thermal camera 200 to determine that an area where the temperature drop from the time the disinfectant is applied until it evaporates is greater than or equal to a predetermined threshold is an area where the disinfectant has been sufficiently applied.
[0056] An area where the disinfectant solution has been sufficiently applied is an area where the minimum amount of disinfectant solution necessary for disinfection has been applied, or an area where the disinfectant solution has been applied in excess of or above the prescribed standard. In short, it is an area where disinfection was successful (hereinafter also referred to as the "successful disinfection area"). Below, two examples of the first determination will be explained with reference to Figures 5 and 6, describing the relevant parts and their operations.
[0057] <<First example of the first determination>> Refer to Figure 5 to explain the first example of the first determination.
[0058] S100-111: When the input device 600 receives an instruction to start the determination operation of the wiping and disinfection determination device 100, information instructing the wiping and disinfection determination device 100 to start its determination operation is output from the input device 600 and input to the wiping and disinfection determination device 100, thereby allowing the wiping and disinfection determination device 100 to receive the instruction to start its determination operation.
[0059] The user gives the instruction to start the determination operation of the wipe-and-disinfectant determination device 100, which is received by the input device 600. In other words, the user gives the instruction to start the determination operation of the wipe-and-disinfectant determination device 100 to the input device 600 before starting to spray the disinfectant solution.
[0060] S100-112: When the instruction to start the determination operation is received in S100-111, the thermal image acquisition unit 110 acquires the thermal image captured by the thermal camera 200 at that time and outputs the acquired thermal image as the background thermal image to the first determination unit 150.
[0061] Since S100-112 is performed immediately after S100-111, the spraying of the disinfectant solution will begin after S100-112.
[0062] S100-113: When the input device 600 receives a designation that the disinfectant spraying is complete, information representing that designation is output from the input device 600 and input to the wipe-and-disinfectant determination device 100, thereby the wipe-and-disinfectant determination device 100 accepts the designation that the disinfectant spraying is complete.
[0063] Furthermore, the user is responsible for designating the completion of disinfectant spraying to the input device 600. In other words, once the user has finished spraying the disinfectant, they designate the input device 600 that the disinfectant spraying is complete.
[0064] S100-114: Once the designation that the disinfectant spraying is complete is received in S100-113, the thermal image acquisition unit 110 acquires the thermal image taken at that time by the thermal camera 200 and outputs the acquired thermal image as a post-spray thermal image to the first determination unit 150.
[0065] S100-115: After S100-114, the first determination unit 150 determines that an area formed by a set of pixels where the value obtained by subtracting the pixel value of the post-spray thermal image (i.e., the temperature value after spraying the disinfectant) from the pixel value of the background thermal image (i.e., the temperature value before spraying the disinfectant) is greater than or equal to a predetermined threshold is an area where the disinfectant has been sufficiently applied. After completing S100-115, the cleaning and disinfection determination device 100 terminates the processing of the first example of the first determination.
[0066] <<Second example of the first determination>> Referring to Figure 6, a second example of the first determination will be explained.
[0067] S100-121: When the input device 600 receives an instruction to start the determination operation of the wiping and disinfection determination device 100, information instructing the wiping and disinfection determination device 100 to start its determination operation is output from the input device 600 and input to the wiping and disinfection determination device 100, thereby allowing the wiping and disinfection determination device 100 to receive the instruction to start its determination operation.
[0068] The user gives the instruction to start the determination operation of the wipe-and-disinfectant determination device 100, which is received by the input device 600. In other words, the user gives the instruction to start the determination operation of the wipe-and-disinfectant determination device 100 to the input device 600 before starting to spray the disinfectant solution.
[0069] S100-122: When the instruction to start the determination operation is received in S100-121, the thermal image acquisition unit 110 acquires the thermal image captured by the thermal camera 200 at that time and outputs the acquired thermal image as the background thermal image to the first determination unit 150.
[0070] S100-123: When the instruction to start the determination operation is received in S100-121, the object image acquisition unit 120 acquires the object image captured by the object camera 300 at that time and outputs the acquired object image as the background object image to the first determination unit 150.
[0071] Since steps S100-122 and S100-123 are performed immediately after S100-121, the spraying of the disinfectant solution will begin after steps S100-122 and S100-123.
[0072] S100-124: After the predetermined time elapsed in S100-122, or after the predetermined time elapsed in the previous S100-124, the thermal image acquisition unit 110 acquires the thermal image captured by the thermal camera 200 and outputs the acquired thermal image to the first determination unit 150.
[0073] S100-125: At the same time as S100-124, the object image acquisition unit 120 acquires an object image captured by the object camera 300 and outputs the acquired object image to the first determination unit 150.
[0074] S100-126: The first determination unit 150 controls the system to proceed to the S100-127 process if, among all pixels of the thermal image acquired in S100-124, the pixel value of the thermal image acquired in S100-124 is smaller than the pixel value of the background thermal image (i.e., pixels whose temperature has decreased since before the disinfectant was sprayed), and if the object image acquired in S100-125 is approximately equal to the background object image (i.e., the disinfectant spraying process has been completed). Otherwise, it controls the system to proceed to the S100-124 and S100-125 processes.
[0075] Furthermore, whether the object image acquired in S100-125 is approximately equal to the background object image can be determined, for example, by whether the difference between the object image acquired in S100-125 and the background object image is less than or equal to a predetermined threshold, or whether the similarity between the object image acquired in S100-125 and the background object image is greater than or equal to a threshold.
[0076] Furthermore, the condition that the proportion of pixels in the thermal image acquired in S100-124 whose pixel value is smaller than the pixel value of the background thermal image is greater than or equal to a predetermined threshold is equivalent to the disinfectant being sprayed over a wide area.
[0077] Furthermore, the condition that the object image acquired in S100-125 is approximately equal to the background object image corresponds to the fact that the sprayer and disinfection worker are no longer within the imaging range. Therefore, by determining that both of these conditions are met, it is possible to determine that the disinfectant spraying operation has been completed.
[0078] S100-127: The first determination unit 150 determines that an area formed by a set of pixels where the value obtained by subtracting the pixel value of the thermal image acquired in S100-124 and used in S100-126 (i.e., the temperature value after spraying the disinfectant) from the pixel value of the background thermal image (i.e., the temperature value before spraying the disinfectant) is greater than or equal to a predetermined threshold is an area where the disinfectant has been sufficiently applied. After completing S100-127, the cleaning and disinfection determination device 100 terminates the processing of the second example of the first determination.
[0079] The first determination unit 150 may also obtain an image (hereinafter also referred to as the "first determination result image") that distinguishes between a first region (i.e., a disinfection success region), which is a region in the shooting range where the disinfectant solution determined by the first determination has been sufficiently applied, and a region that is not the first region (i.e., a region that is not a disinfection success region, a region where disinfection was unsuccessful, a disinfection failure region).
[0080] An example of the first determination result image obtained by the first determination unit 150 is an image of the shooting range, as shown in Figure 7, in which the first region is a certain light color and the region that is not the first region is a certain dark color. For the sake of illustration, in Figure 7, the "certain light color" is shown in white and the "certain dark color" is shown in black.
[0081] The first judgment result image obtained by the first judgment unit 150 is output from the cleaning and disinfection judgment device 100, input to the display device 500, and displayed by the display device 500, making it visible.
[0082] Furthermore, the first determination unit 150 may calculate the ratio of at least one of the disinfection success area and the disinfection failure area to the area to be wiped and disinfected, and obtain this ratio as the scoring result for the disinfection work. The scoring result obtained by the first determination unit 150 may be output from the wipe-disinfection determination device 100, input to the display device 500, and displayed by the display device 500 so that it can be visually confirmed.
[0083] <Second Judgment> In the first embodiment of the wiping and disinfection determination device 100, the second determination unit 160 uses the image of the physical object captured by the physical object camera 300 and the pressure information detected by the pressure sensor 4 provided on the wiping tool 400 to determine that the area within the first region obtained in the first determination where the pressure is greater than or equal to a predetermined threshold is a successful wiping and disinfection region. Below, an example of the second determination will be described with reference to Figure 8, explaining the relevant parts and their operations.
[0084] <<Example of the second judgment>> S100-211: At the time following the first determination, the physical object image acquisition unit 120 acquires the physical object image captured by the physical object camera 300 and outputs it to the second determination unit 160.
[0085] S100-212: For the same time as S100-211, the second determination unit 160 controls the cleaning and disinfection determination device 100 to terminate its second determination if all the images of the physical object from the time of that time up to a predetermined time in the past are approximately the same, and controls the device to perform the processes of S100-213 and S100-214 otherwise. "All the images of the physical object from the time of that time up to a predetermined time in the past are approximately the same" corresponds to the case where the cleaning work is completed and the cleaning tool 400, which should have been moving during the cleaning work, is no longer included in the images of the physical object for a predetermined time.
[0086] Furthermore, whether an image of an object at a certain time (referred to as object image 1) and an image of an object at a different time (referred to as object image 2) are approximately equal can be determined by whether the difference between object image 1 and object image 2 is less than or equal to a predetermined threshold, or whether the similarity between object image 1 and object image 2 is greater than or equal to a threshold.
[0087] Alternatively, instead of all object images from the time in question up to a predetermined time prior being approximately identical, the input device 600 may be controlled to terminate the second determination of the wiping and disinfection determination device 100 when it receives an instruction to terminate the second determination of the wiping and disinfection determination device 100.
[0088] In this case, the user gives the instruction to the input device 600 to complete the second determination of the wipe-and-disinfectant determination device 100. That is, once the wipe-and-disinfectant work is completed, the user gives the input device 600 the instruction to complete the second determination of the wipe-and-disinfectant determination device 100.
[0089] S100-213: At the time when the process of S100-213 and S100-214 is controlled in S100-212, the pressure acquisition unit 130 acquires pressure information detected by the pressure sensor 4 provided on the cleaning tool 400, obtains a pressure value from the pressure information, and outputs it to the second determination unit 160.
[0090] S100-214: At the same time as S100-213 (i.e., the time at which S100-212 is controlled to perform the processes of S100-213 and S100-214), the second determination unit 160 acquires the position within the shooting range of the cleaning part 7 of the cleaning tool 400 included in the image of the physical object (hereinafter also referred to as the "cleaning position").
[0091] S100-215: For the same time as S100-213, the second determination unit 160 obtains the first region obtained by the first determination unit 150 and the pressure value obtained by the processing in S100-213. If the wiping position at that time is within the first region and the pressure value at that time is greater than or equal to a predetermined threshold, the wiping position at that time is added to the area of successful wiping and disinfection.
[0092] S100-216: For the same time as S100-213, the second determination unit 160 controls the system to perform the S100-211 process for the next time, which is a predetermined time interval after that time.
[0093] The second determination unit 160 may also obtain an image (hereinafter also referred to as the "second determination result image") in which the areas of the imaging range in which wiping and disinfection was successful and areas in which wiping and disinfection was not successful (i.e., areas in which wiping and disinfection was unsuccessful) are distinguished and made visible.
[0094] Alternatively, the second determination unit 160 may also obtain an image (hereinafter also referred to as the "first determination and second determination result image") in which the areas of the imaging range in which wiping and disinfection were successful, areas within the first area (i.e., disinfection successful area) in which wiping and disinfection were unsuccessful, and areas that are not part of the first area (i.e., disinfection unsuccessful areas) are distinguished and made visible.
[0095] As shown in Figure 9, an example of the judgment result image for the first and second judgments is an image of the shooting range in which the area where wiping and disinfection was successful is gray, the area where wiping and disinfection was unsuccessful is white, and the area where disinfection was unsuccessful is black. The judgment result image for the second judgment or the judgment result images for the first and second judgments obtained by the second judgment unit 160 is output from the wiping and disinfection judgment device 100, input to the display device 500, and displayed by the display device 500 to be made visible.
[0096] Furthermore, the second determination unit 160 may calculate the ratio of at least one of the areas where wiping and disinfection was successful, areas where wiping and disinfection was unsuccessful, and areas within the successful disinfection area where wiping and disinfection was unsuccessful, to the area to be wiped and disinfected, and obtain this ratio as the scoring result for the wiping and disinfection work. The scoring result obtained by the second determination unit 160 may be output from the wiping and disinfection determination device 100, input to the display device 500, and displayed by the display device 500 so that it can be visually confirmed.
[0097] (Second Embodiment) Next, a second embodiment will be described. In the second embodiment, a configuration that differs in part from the first embodiment of the wiping and disinfection determination device, which determines that an area within the area to be wiped and disinfected is a successful wiping and disinfection area in which sufficient disinfectant solution is applied during the application of the disinfectant solution and sufficient pressure is applied during the wiping process, will be described. Below, we will explain the similarities and differences with the first embodiment, and focus on the points that differ from the first embodiment.
[0098] [Wipe-to-disinfectant determination system 11 and wipe-to-disinfectant determination device 101] Figure 10 is a diagram showing an example of the functional configuration of the wipe-and-disinfectant determination system 11 in the second embodiment. As shown in Figure 10, the wipe-and-disinfectant determination system 11 in the second embodiment includes a wipe-and-disinfectant determination device 101, a thermal camera 200, a physical object camera 300, a wiping tool 400, a display device 500, and an input device 600.
[0099] As shown in Figure 10, the second embodiment of the wipe-and-disinfect determination device 101 includes a thermal image acquisition unit 110, an object image acquisition unit 120, a pressure acquisition unit 130, a first determination unit 150, a second determination unit 161, and a third determination unit 170.
[0100] The second embodiment of the wipe-and-disinfect determination device 101 differs from the first embodiment of the wipe-and-disinfect determination device 100 in that it includes a second determination unit 161 instead of the second determination unit 160, and also includes a third determination unit 170. The configuration and operation of the thermal image acquisition unit 110, physical object image acquisition unit 120, pressure acquisition unit 130, and first determination unit 150, which are assigned the same reference numbers as in the first embodiment, are the same as in the first embodiment.
[0101] As shown in Figure 10, the wipe-and-disinfectant determination device 101 is connected to a thermal camera 200, an object camera 300, a wiping tool 400, a display device 500, and an input device 600, similar to the wipe-and-disinfectant determination device 100. The configuration and operation of the thermal camera 200, object camera 300, wiping tool 400, display device 500, and input device 600, which are assigned the same reference numbers as in the first embodiment, are the same as in the first embodiment.
[0102] [Wipe-and-disinfectant detection device 101] The wiping and disinfection determination device 101, based on a first determination by the first determination unit 150 described in the first embodiment, determines the area within the imaging range including the area to be wiped and disinfected where sufficient disinfectant solution was applied during the disinfectant solution application process (i.e., the "first area"). Furthermore, based on a second determination by the second determination unit 161 described below, it determines the area within the imaging range including the area to be wiped and disinfected where sufficient pressure was applied during the wiping process (hereinafter also referred to as the "second area"). Furthermore, based on a third determination by the third determination unit 170 described below, it determines that the overlapping area of the first area and the second area is a successful wiping and disinfection area. The second determination, which differs from that of the first embodiment, and the third determination, which was not included in the first embodiment, will be described below.
[0103] Furthermore, the area where sufficient pressure is applied is the area where the minimum amount of pressure necessary for wiping is applied, and in short, it is the area where wiping was successful (hereinafter also referred to as the "successful wiping area").
[0104] <Second Judgment> In the second embodiment of the wiping and disinfection determination device 101, the second determination unit 161 uses the image of the physical object captured by the physical object camera 300 and the pressure information detected by the pressure sensor 4 provided on the wiping tool 400 to determine a second region, which is a region within the shooting range including the area to be wiped and disinfected, where the pressure is greater than or equal to a predetermined threshold. Below, an example of the second determination will be described with reference to Figure 11, explaining the relevant parts and their operations.
[0105] <<Example of the second judgment>> S101-221: At the time following the first determination, the physical object image acquisition unit 120 acquires the physical object image captured by the physical object camera 300 and outputs it to the second determination unit 161.
[0106] S101-222: For the same time period as S101-221, the second determination unit 161 controls the cleaning and disinfection determination device 101 to terminate its second determination if all object images from the object image at that time up to a predetermined time prior are approximately the same; otherwise, it controls the device to perform the process in S100-223.
[0107] The phrase "when all images of the physical object from the image of the physical object at the relevant time to a predetermined time prior to that time are approximately the same" corresponds to the case where the cleaning work is completed and the cleaning tool 400, which should have been moving during the cleaning work, is no longer included in the image of the physical object for a certain period of time.
[0108] Alternatively, instead of all physical object images from the time in question up to a predetermined time prior being approximately identical, the input device 600 may be controlled to terminate the second determination of the wiping and disinfecting determination device 101 when it receives an instruction from the wiping and disinfecting determination device 101 to terminate the second determination. In this case, the instruction from the user to terminate the second determination of the wiping and disinfecting determination device 101 received by the input device 600 is made by the user. That is, when the wiping work is completed, the user gives an instruction to the input device 600 to terminate the second determination of the wiping and disinfecting determination device 101.
[0109] S101-223: At the time when the process of S101-223 and S100-224 is controlled in S101-222, the pressure acquisition unit 130 acquires pressure information detected by the pressure sensor 4 provided on the cleaning tool 400, obtains a pressure value from the pressure information, and outputs it to the second determination unit 161.
[0110] S101-224: At the same time as S101-223 (i.e., the time when S101-222 is controlled to perform the processes of S101-223 and S101-224), the second determination unit 161 acquires the position within the shooting range of the cleaning part of the cleaning tool 400 included in the physical object image (i.e., the "cleaning position").
[0111] S101-225: For the same time period as S101-223, the second determination unit 161 acquires the pressure value obtained by the processing in S101-223, and if the pressure value at that time is greater than or equal to a predetermined threshold, the wiping position at that time is added to the second region.
[0112] S101-226: For the same time as S101-223, the second determination unit 161 controls the process to perform S101-221 for the next time, which is a predetermined time interval after that time.
[0113] When the cleaning and disinfection determination device 101 is controlled by S101-222 to complete the second determination for that time, the second determination unit 161 obtains the final second region by S101-225. The second determination unit 161 outputs this finally obtained second region. The second region output by the second determination unit 161 is input to the third determination unit 170.
[0114] <Third Judgment> The third determination unit 170 receives the first region obtained by the first determination unit 150 and the second region obtained by the second determination unit 150 as input. The third determination unit 170 determines that the overlapping region of the first region and the second region is the region where wiping and disinfection was successful (hereinafter also referred to as the "third region").
[0115] The third determination unit 170 may also obtain an image (hereinafter also referred to as the "third determination result image") in which the areas of the shooting range in which wiping and disinfection was successful and the areas in which wiping and disinfection was not successful (i.e., the "unsuccessful wiping and disinfection areas") are distinguished and made visible. Alternatively, the third determination unit 170 may also obtain an image (hereinafter also referred to as the "first determination and third determination result images") in which the areas of the shooting range in which wiping and disinfection was successful, the areas of the first area (i.e., the successful disinfection area) in which wiping and disinfection was not successful, and the areas that are not the first area (i.e., unsuccessful disinfection areas) are distinguished and made visible.
[0116] Examples of the judgment result images for the first and third judgments are shown in Figure 9, which is the same as the examples of the judgment result images for the first and second judgments in the first embodiment. The judgment result image for the third judgment or the judgment result images for the first and third judgments obtained by the third judgment unit 170 are output from the cleaning and disinfection judgment device 101, input to the display device 500, and displayed by the display device 500, making them visible.
[0117] Furthermore, the third determination unit 170 may calculate the ratio of at least one of the areas where wiping and disinfection was successful, areas where wiping and disinfection was unsuccessful, and areas within the successful disinfection area where wiping and disinfection was unsuccessful, to the area to be wiped and disinfected, and obtain this ratio as the scoring result for the wiping and disinfection work. The scoring result obtained by the third determination unit 170 may be output from the wiping and disinfection determination device 101, input to the display device 500, and displayed by the display device 500 so that it can be visually confirmed.
[0118] (Third embodiment) Next, as a third embodiment, we will describe a configuration in which, for the first determination, a near-infrared image captured by an InGaAs camera is used instead of a thermal image captured by a thermal camera 200. Below, we will explain the similarities and differences between the first and second embodiments, and provide a description focusing on the differences between the first and second embodiments.
[0119] [Wipe-to-disinfectant determination system 12 and wipe-to-disinfectant determination device 102] Figure 12 is a diagram showing an example of the functional configuration of the wipe-and-disinfectant determination system 12 in the third embodiment based on the first embodiment. As shown in Figure 12, the wipe-and-disinfectant determination system 12 in the third embodiment based on the first embodiment includes a wipe-and-disinfectant determination device 102, an InGaAs camera 202, a physical object camera 300, a wipe tool 400, a display device 500, and an input device 600.
[0120] The third embodiment of the wipe-and-disinfectant determination device 102 based on the first embodiment includes a near-infrared image acquisition unit 112, an object image acquisition unit 120, a pressure acquisition unit 130, a first determination unit 152, and a second determination unit 160. The difference between the wipe-and-disinfectant determination device 102 of the third embodiment based on the first embodiment and the wipe-and-disinfectant determination device 100 of the first embodiment is that it includes a near-infrared image acquisition unit 112 instead of a thermal image acquisition unit 110, and a first determination unit 152 instead of a first determination unit 150. The configuration and operation of the object image acquisition unit 120, pressure acquisition unit 130, and second determination unit 160, which are assigned the same reference numbers as in the first embodiment, are the same as in the first embodiment.
[0121] As shown in Figure 12, the cleaning and disinfection determination device 102 is connected to an InGaAs camera 202, a physical object camera 300, a cleaning tool 400, a display device 500, and an input device 600. The configuration and operation of the physical object camera 300, cleaning tool 400, display device 500, and input device 600, which are assigned the same reference numerals as in the first embodiment, are the same as in the first embodiment.
[0122] [InGaAs Camera 202] The InGaAs camera 202 is a camera that captures near-infrared light in the wavelength range of 900 nm to 1700 nm. The InGaAs camera 202 captures a near-infrared image, which is composed of images acquired from the InGaAs camera 202 side of near-infrared light in the wavelength range of 900 nm to 1700 nm, with the same shooting range as the physical object camera 300. If the work surface of the safety cabinet is the area to be wiped and disinfected, the shooting range is the work surface of the safety cabinet that is the area to be wiped and disinfected. The near-infrared image captured by the InGaAs camera 202 is input to the near-infrared image acquisition unit 112.
[0123] Furthermore, the InGaAs camera 202 may be equipped with a bandpass filter to facilitate the distinction between liquid-wetted and non-liquid regions in the near-infrared image. The passband of the bandpass filter may be, for example, 1450 ± 32 nm. In addition, to facilitate the distinction between liquid-wetted and non-liquid regions in the near-infrared image, the cleaning and disinfection determination system 12 may be equipped with an irradiator (not shown) that emits near-infrared light in the wavelength band obtained by the InGaAs camera 202 or at least the passband of the aforementioned bandpass filter, thereby irradiating the imaging range with near-infrared light in the wavelength band obtained by the InGaAs camera 202 or at least the passband of the aforementioned bandpass filter.
[0124] [Wipe-and-disinfectant detection device 102] First, the wiping and disinfection determination device 102 determines, by the first determination unit 152, the area within the imaging range that includes the area to be wiped and disinfected, where the disinfectant solution was sufficiently applied during the application process (i.e., the "first area"). Furthermore, by the second determination unit 160, as described in the first embodiment, it determines that the area within the first area where sufficient pressure was applied during the wiping process is the area where wiping and disinfection was successful. The first determination, which differs from that of the first embodiment, will be described below.
[0125] <First Judgment> In the third embodiment of the wipe-and-disinfectant determination device 102 based on the first embodiment, the first determination unit 152 identifies wet areas using near-infrared images captured by the InGaAs camera 202 within the shooting range including the area to be wiped and disinfected, and determines that the identified areas are areas where disinfectant has been sufficiently applied (i.e., "first areas").
[0126] As explained in the first embodiment, an area where the disinfectant solution has been sufficiently applied is an area where the minimum amount of disinfectant solution necessary for disinfection has been applied, or an area where the disinfectant solution has been applied in excess of or above a predetermined standard; in short, it is an area where disinfection has been successfully achieved, i.e., a disinfection success area. Below, two examples of the first determination in the third embodiment will be described with reference to Figures 13 and 14, explaining the relevant parts and their operations.
[0127] <<First example of the first determination of the third embodiment>> Refer to Figure 13 to explain the first example of the first determination.
[0128] S102-131: When the input device 600 receives an instruction to start the determination operation of the wiping and disinfection determination device 102, information instructing the wiping and disinfection determination device 102 to start its determination operation is output from the input device 600 and input to the wiping and disinfection determination device 102, thereby allowing the wiping and disinfection determination device 102 to receive the instruction to start its determination operation.
[0129] The user gives the instruction to start the determination operation of the wipe-and-disinfection determination device 102, which is received by the input device 600. In other words, the user gives the instruction to start the determination operation of the wipe-and-disinfection determination device 102 to the input device 600 before starting to spray the disinfectant solution.
[0130] S102-132: When the instruction to start the determination operation is received in S102-131, the near-infrared image acquisition unit 112 acquires the near-infrared image captured by the InGaAs camera 202 at that time and outputs the acquired near-infrared image to the first determination unit 152 as the background near-infrared image.
[0131] Since S102-132 is performed immediately after S102-131, the spraying of the disinfectant will begin after S102-132.
[0132] S102-133: When the input device 600 receives a designation that the disinfectant spraying is complete, information representing that designation is output from the input device 600 and input to the wipe-disinfection determination device 102, so that the wipe-disinfection determination device 100 receives the designation that the disinfectant spraying is complete.
[0133] Furthermore, the user is responsible for designating the completion of disinfectant spraying to the input device 600. In other words, once the user has finished spraying the disinfectant, they designate the input device 600 that the disinfectant spraying is complete.
[0134] S102-134: Once the designation that the disinfectant spraying is complete is received in S102-133, the near-infrared image acquisition unit 112 acquires the near-infrared image taken at that time by the InGaAs camera 202 and outputs the acquired near-infrared image as the post-spray near-infrared image to the first determination unit 152.
[0135] S102-135: After S102-134, the first determination unit 152 identifies sufficiently wet areas by image recognition of the difference portion of the near-infrared image after spraying from the background near-infrared image, and determines that the identified areas are areas that have been sufficiently coated with disinfectant. After completing S102-135, the cleaning and disinfection determination device 102 terminates the processing of the first example of the first determination.
[0136] <<Second example of the first determination in the third embodiment>> Referring to Figure 14, a second example of the first determination will be explained.
[0137] S102-141: When the input device 600 receives an instruction to start the determination operation of the wiping and disinfection determination device 102, information instructing the wiping and disinfection determination device 102 to start its determination operation is output from the input device 600 and input to the wiping and disinfection determination device 102, thereby allowing the wiping and disinfection determination device 102 to receive the instruction to start its determination operation.
[0138] The user gives the instruction to start the determination operation of the wipe-and-disinfection determination device 102, which is received by the input device 600. In other words, the user gives the instruction to start the determination operation of the wipe-and-disinfection determination device 102 to the input device 600 before starting to spray the disinfectant solution.
[0139] S102-142: When the instruction to start the determination operation is received in S102-141, the near-infrared image acquisition unit 112 acquires the near-infrared image captured by the InGaAs camera 202 at that time and outputs the acquired near-infrared image to the first determination unit 152 as the background near-infrared image.
[0140] S102-143: When the instruction to start the determination operation is received in S102-141, the object image acquisition unit 120 acquires the object image captured by the object camera 300 at that time and outputs the acquired object image as the background object image to the first determination unit 152.
[0141] Since steps S102-142 and S102-143 are performed immediately after S102-141, the spraying of disinfectant will begin after steps S102-142 and S102-143.
[0142] S102-144: After the predetermined time elapsed in S102-142, or after the predetermined time elapsed in the previous S100-144, the near-infrared acquisition unit 112 acquires the near-infrared image captured by the InGaAs camera 202 and outputs the acquired near-infrared image to the first determination unit 152.
[0143] S102-145: At the same time as S102-144, the object image acquisition unit 120 acquires an object image captured by the object camera 300 and outputs the acquired object image to the first determination unit 152.
[0144] S102-146: The first determination unit 152 controls the system to proceed to the S102-147 process if, among all pixels of the near-infrared image acquired in S102-144, the proportion of pixels where the pixel value of the near-infrared image acquired in S102-144 differs from the pixel value of the background near-infrared image is greater than or equal to a predetermined threshold, and the object image acquired in S102-145 is approximately equal to the background object image (i.e., the disinfectant spraying operation is completed). Otherwise, it controls the system to proceed to the S102-144 and S102-145 processes.
[0145] Furthermore, whether the object image acquired in S102-145 is approximately equal to the background object image can be determined, for example, by whether the difference between the object image acquired in S102-145 and the background object image is less than or equal to a predetermined threshold, or whether the similarity between the object image acquired in S102-145 and the background object image is greater than or equal to a threshold.
[0146] Furthermore, satisfying the condition that the proportion of pixels in the near-infrared image acquired in S102-144 whose pixel values differ from those of the background near-infrared image is greater than or equal to a predetermined threshold corresponds to the widespread dispersal of the disinfectant solution.
[0147] Furthermore, the condition that the object image acquired in S102-145 is approximately equal to the background object image corresponds to the fact that the sprayer and disinfection worker are no longer within the imaging range. Therefore, by determining that both of these conditions are met, it is possible to determine that the disinfectant spraying operation has been completed.
[0148] S102-147: The first determination unit 152 identifies sufficiently wet areas by performing image recognition on the difference portion between the near-infrared image acquired in S102-144 and used in S102-146 and the background near-infrared image, and determines that the identified areas are areas that have been sufficiently coated with disinfectant. After completing S100-147, the cleaning and disinfection determination device 102 terminates the processing of the second example of the first determination.
[0149] The first determination unit 152 may also obtain an image (hereinafter also referred to as the "first determination result image") that distinguishes between a first region (i.e., a disinfection success region) which is a region in the shooting range where the disinfectant solution determined by the first determination has been sufficiently applied, and a region that is not the first region (i.e., a region that is not a disinfection success region, a region where disinfection was unsuccessful, a disinfection failure region). An example of the first determination result image obtained by the first determination unit 152 is the same as the example of the first determination result image in the first embodiment, shown in Figure 7. The first determination result image obtained by the first determination unit 152 is output from the wiping disinfection determination device 102, input to the display device 500, and displayed by the display device 500 to make it visible.
[0150] Furthermore, the first determination unit 152 may calculate the ratio of at least one of the disinfection success area and the disinfection failure area to the area to be wiped and disinfected, and obtain this ratio as the scoring result for the disinfection work. The scoring result obtained by the first determination unit 152 may be output from the wipe-disinfection determination device 102, input to the display device 500, and displayed by the display device 500 so that it can be visually confirmed.
[0151] [Wipe-to-disinfectant determination system 13 and wipe-to-disinfectant determination device 103] Figure 15 is a diagram showing an example of the functional configuration of the wipe-and-disinfectant determination system 13 in the third embodiment based on the second embodiment. As shown in Figure 15, the wipe-and-disinfectant determination system 13 in the third embodiment based on the second embodiment includes a wipe-and-disinfectant determination device 103, an InGaAs camera 202, a physical object camera 300, a wiping tool 400, a display device 500, and an input device 600.
[0152] The third embodiment of the wipe-and-disinfect determination device 103 based on the second embodiment includes a near-infrared image acquisition unit 112, an object image acquisition unit 120, a pressure acquisition unit 130, a first determination unit 152, a second determination unit 161, and a third determination unit 170.
[0153] The third embodiment of the wipe-and-disinfectant determination device 103, based on the second embodiment, differs from the wipe-and-disinfectant determination device 101 of the second embodiment in that it includes a near-infrared image acquisition unit 112 instead of a thermal image acquisition unit 110, and a first determination unit 152 instead of a first determination unit 150. The configuration and operation of the physical object image acquisition unit 120, pressure acquisition unit 130, second determination unit 161, and third determination unit 170, which are assigned the same reference numbers as in the second embodiment, are the same as in the second embodiment. The configuration and operation of the near-infrared image acquisition unit 112 and first determination unit 152, which are assigned the same reference numbers as in the third embodiment based on the first embodiment, are the same as in the third embodiment based on the first embodiment.
[0154] As shown in Figure 15, the cleaning and disinfection determination device 103 is connected to an InGaAs camera 202, a physical object camera 300, a cleaning tool 400, a display device 500, and an input device 600.
[0155] The configuration and operation of the physical object camera 300, cleaning tool 400, display device 500, and input device 600, which are assigned the same reference numbers as in the second embodiment, are the same as in the second embodiment. The configuration and operation of the InGaAs camera 202, which is assigned the same reference numbers as in the third embodiment based on the first embodiment, are the same as in the third embodiment based on the first embodiment.
[0156] As can be seen from the first determination of the third embodiment described above and the first determination of the first embodiment, the first determination is a process of determining a first region (i.e., a disinfection success region) which is a region within a range to be wiped and disinfected, composed of surfaces included in a certain space, to which disinfectant solution has been applied in greater amounts than or equal to a predetermined first standard. As can be seen from the fact that each example of the first determination described in the first embodiment is compared with a threshold for each pixel, the aforementioned "more or equal to a predetermined first standard of disinfectant solution applied" refers, for example, to a unit area.
[0157] (Fourth Embodiment) Next, the fourth embodiment will be described. The cleaning tool 400 described in the first embodiment is equipped with output wiring that outputs pressure information detected by the pressure sensor 4 to the pressure acquisition unit 130. As a result, there is a problem that the image of the output wiring is included in the thermal image taken by the thermal camera 200, the physical image taken by the physical camera 300, and the near-infrared image taken by the InGaAs camera 202. Therefore, the cleaning tool 401 of the fourth embodiment is configured so that pressure information detected by the pressure sensor 4 is input to the pressure acquisition unit 130, but the cleaning tool is not equipped with output wiring.
[0158] The fourth embodiment of the cleaning tool 401 includes, in addition to all parts and components other than the output wiring of the cleaning tool 400 described in the first embodiment, a display unit 8 that displays information indicating the magnitude and / or size of the pressure detected by the pressure sensor 4.
[0159] The first example of the indicator unit 8 of the fourth embodiment of the cleaning tool 401 is one or more indicator lamps 81 provided on the side of the cleaning part 7 opposite to the cleaning surface (hereinafter referred to as the "top surface"), as illustrated in Figure 16. The indicator lamps 81 are, for example, LEDs. Figure 16 shows an image of the cleaning tool 401 viewed from diagonally above. Figure 16 also shows the gripping part 1 and the cleaning part 7 of the cleaning tool 401. The left side (a) of Figure 16 shows the state without pressure, and the right side (b) shows the state with pressure.
[0160] As shown in Figures 16(a) and (b), two indicator lamps 81 are provided on the upper surface of the cleaning part 7. The number of indicator lamps 81 is not limited to two; there may be one or three or more. Furthermore, the indicator lamps 81 may be provided anywhere on the cleaning part 7 as long as the light from the indicator lamps 81 is visible from outside the cleaning part 7 when they are lit.
[0161] Figure 17 shows an example of the functional configuration related to pressure display in the cleaning component 7 of the fourth embodiment. As shown in Figure 17, the cleaning component 7 of the fourth embodiment includes a pressure sensor 4, a control circuit 71, a battery 72, and an indicator lamp 81 as functions related to pressure display.
[0162] The control circuit 71 controls the indicator lamp 81 to light up when the pressure detected by the pressure sensor 4 is greater than or equal to a predetermined threshold, and to turn off the indicator lamp otherwise (hereinafter also referred to as "first display control").
[0163] Furthermore, the control circuit 71 may control the indicator lamp 81 to light up brighter the greater the pressure detected by the pressure sensor 4 (hereinafter also referred to as "second display control"). Also, if the display unit 8 is equipped with multiple indicator lamps 81, the control circuit 71 may perform the first display control on some of the multiple indicator lamps and the second display control on the remaining indicator lamps 81.
[0164] A second example of the display unit 8 of the fourth embodiment of the cleaning tool 401 is one or more pressure indicator components 82 that are visible from the top surface of the cleaning component 7, as illustrated in Figure 18. Figure 18 shows an image of the pressure indicator component 81 when viewed from the side. Also, (a) on the left side of Figure 18 shows the state without pressure, and (b) on the right side shows the state with pressure.
[0165] In the example in Figure 18, the pressure indicator component 82 is shown as being supported by the hard surface 3. In other words, Figure 18(a) shows an image of the case where there is no pressure between the cleaning surface 5 and the hard surface 3, and Figure 18(b) shows an image of the case where there is pressure between the cleaning surface 5 and the hard surface 3.
[0166] The shape of the pressure indicator component 82 is not limited to a specific shape, but may be spherical, for example. The material of the pressure indicator component 82 may be any material that changes color depending on the pressure applied to it. The cleaning tool 401 may have one or more pressure indicator components 82. Furthermore, the pressure indicator component 82 may be a rotating component.
[0167] The pressure indicator component 82 is a component such that, for example, if a pressure greater than or equal to a predetermined threshold is generated between the cleaning surface 5 and the hard surface 3, a first color (e.g., red) is visible from the top surface, and if not, a second color (e.g., gray) is visible from the top surface. In the second example, since the pressure indicator component 82 also functions as a pressure sensor, the cleaning tool 401 does not need to be equipped with a pressure sensor 4 in addition to the pressure indicator component 82.
[0168] Although the pressure indicator component 82 illustrated in Figure 18 is a rotating component, the pressure indicator component 82 may also be a component in which the first and second colors are visible from above due to expansion and contraction in response to pressure. For example, the pressure indicator component 82 may be spherical (ball-shaped) when no pressure is applied, and deform and change color when pressure is applied. The material of the pressure indicator component 82 may be rubber.
[0169] When using the cleaning tool 401 of the fourth embodiment, the pressure acquisition unit 130 of the cleaning and disinfection determination device 100-103 does not receive pressure information detected by the pressure sensor from the cleaning tool 401. Instead, the physical object image acquisition unit 120 obtains pressure information by image recognition of the display state of the display unit 8 of the cleaning tool 401 included in the input physical object image, and pressure information is input from the physical object image acquisition unit 120 to the pressure acquisition unit 130, as shown by the dotted lines in Figures 3, 10, 12, and 15.
[0170] Using the cleaning tool 401 of the fourth embodiment solves the problem of output wiring images being included in the thermal image captured by the thermal camera 200, the physical image captured by the physical camera 300, and the near-infrared image captured by the InGaAs camera 202. Furthermore, by using the cleaning tool 401 of the fourth embodiment, the worker performing the cleaning can grasp the cleaning status in real time by viewing the display unit 8, thus enabling the cleaning work to be performed more reliably.
[0171] In addition, the cleaning tool 400 of the first embodiment may be equipped with a power supply and a wireless transmitter instead of output wiring, with the wireless transmitter transmitting pressure information and the pressure acquisition unit 130 equipped with a wireless receiver, with the wireless receiver receiving the pressure information.
[0172] (Fifth embodiment) In order to perform the second determination described in the first or second embodiment, the second determination unit 160 or the second determination unit 161 needs to identify the position of the cleaning part 7 of the cleaning tool 400 within the shooting range from the image of the physical object. However, since the work surface of the safety cabinet is made of stainless steel, it can be difficult to accurately identify the position of the cleaning part 7 within the shooting range due to the effect of reflection.
[0173] Therefore, in order to accurately determine the position of the cleaning part 7 within the shooting range, the cleaning tool 402 of the fifth embodiment is equipped with a marker for determining the position of the cleaning surface 5 by shooting with the physical object camera 300.
[0174] The cleaning tool 402 of the fifth embodiment, if the physical camera 300 is a visible light camera, for example, as shown in Figure 19, is composed of a surface area 73 of a predetermined width that is substantially perpendicular to the cleaning surface 5 of the cleaning part 7 described in the first embodiment, and includes a first partial marker that is colored with a first color which has low reflection on the stainless steel surface. A color which has low reflection on the stainless steel surface is, for example, purple.
[0175] Furthermore, a plane (let's call it plane 1) and another plane (let's call it plane 2) are said to be approximately perpendicular if the angle between plane 1 and plane 2 is such that the error from 90 degrees is within α degrees. α is a predetermined threshold.
[0176] Furthermore, if the physical object camera 300 is a visible light camera, the cleaning tool 402 of the fifth embodiment may also include a second partial marker, as illustrated in Figure 19, which is located on the side of the first partial marker that is not in contact with the cleaning surface 5, and is colored in a different color from the first partial marker, and is composed of a surface area 74 that is substantially parallel to the first partial marker. It is desirable that the color of the second partial marker is not only different from the first color, but also has a large color difference from the first color.
[0177] Note that, as shown in Figure 19, the first and second partial markers being approximately parallel and tangent means that the upper edge of the rectangle of the first partial marker, which is a rectangular surface area, and the lower edge of the rectangle of the second partial marker, which is a rectangular surface area, are approximately parallel and tangent. The upper and lower edges being approximately parallel means that the angle between the upper and lower edges is such that the magnitude of the error from 0 degrees is within β degrees. β is a predetermined threshold. Furthermore, the "tangent" state of the first and second partial markers here means that the distance between the upper and lower edges is 0, or that the distance is less than or equal to the threshold.
[0178] For the second part of the marker, if the wiping surface 5 is rectangular, it is preferable that two sets of adjacent surfaces are colored with different colors. It is best to use colors with a large color difference; for example, pink and light green would be suitable.
[0179] Figure 20 shows a top view of the cleaning component 7 when the shape of the cleaning surface 5 is rectangular. The four sides of the cleaning component 7 will be called sides A, B, C, and D, as shown in Figure 20. Figure 21 shows a side view of each side in this case. As shown in Figure 21, each side is provided with a first partial marker and a second partial marker. Note that one or two of the four sides may not be provided with "either or both of the first partial marker and the second partial marker".
[0180] Furthermore, the display unit 8, such as an LED, described in the fourth embodiment, also falls under the category of a marker used to identify the position of the surface to be wiped 5 by being photographed with a camera.
[0181] (Sixth Embodiment) According to the first determination described in the first embodiment, it can be used not only to determine areas where disinfectant solution has been applied, as included in the determination of wiping and disinfecting, but also to determine areas where volatile liquids have been applied. That is, the part that performs the first determination, consisting of the thermal image acquisition unit 110 and the first determination unit 150 enclosed by a dashed line in Figure 3, or the part that performs the first determination, consisting of the thermal image acquisition unit 110, the physical object image acquisition unit 120 and the first determination unit 150 enclosed by a double dashed line in Figure 3, may be operated as the liquid spray determination device 700. The liquid spray determination device 700 may be a standalone device independent of the wiping and disinfecting determination device 100.
[0182] The liquid spraying determination device 700 includes a determination unit that determines that an area within a target range, which is composed of surfaces included in a certain space, is an area where the value obtained by subtracting the temperature after the liquid has been applied from the temperature before the liquid has been applied is greater than or equal to a predetermined threshold, is an area where the liquid spraying was successful (hereinafter also referred to as the "liquid spraying success area").
[0183] The first determination unit 150 may also obtain a determination result image, which is an image that makes it possible to distinguish between the areas in the target range where liquid spraying was successful as determined by the first determination, and areas where liquid spraying was not successful (i.e., areas that are not areas where liquid spraying was successful, areas where liquid spraying was not successful, and areas where liquid spraying was unsuccessful). The determination result image obtained by the first determination unit 150 is output from the liquid spraying determination device 700, input to the display device 500, and displayed by the display device 500, making it visible.
[0184] Furthermore, the first determination unit 150 may calculate the ratio of at least one of the liquid spraying success area and the liquid spraying failure area to the target area, and obtain this ratio as the scoring result for the liquid spraying operation. The scoring result obtained by the first determination unit 150 may be output from the liquid spraying determination device 700, input to the display device 500, and displayed by the display device 500 to be visually verifiable.
[0185] (Example hardware configuration) The devices described in this embodiment (wiping and disinfection determination devices 100-103, and liquid spray determination device 700) can all be realized, for example, by having a computer run a program. This computer may be a physical computer or a virtual machine on the cloud.
[0186] In other words, the device can be realized by using hardware resources such as the CPU and memory built into a computer to execute a program corresponding to the processing performed by the device. The program can be recorded on a computer-readable recording medium (such as portable memory), saved, and distributed. It can also be provided via a network, such as the Internet or email.
[0187] Figure 22 shows an example of the hardware configuration of the computer described above. The computer in Figure 22 has a drive device 1000, an auxiliary storage device 1002, a memory device 1003, a CPU 1004, an interface device 1005, a display device 1006, an input device 1007, an output device 1008, etc., all of which are interconnected by bus B. The computer may also be equipped with a GPU.
[0188] The program that enables processing on the computer is provided, for example, on a recording medium 1001 such as a CD-ROM or memory card. When the recording medium 1001 containing the program is set in the drive device 1000, the program is installed from the recording medium 1001 to the auxiliary storage device 1002 via the drive device 1000. However, the program does not necessarily have to be installed from the recording medium 1001; it may also be downloaded from another computer via a network. The auxiliary storage device 1002 stores the installed program as well as necessary files and data.
[0189] The memory device 1003 reads and stores a program from the auxiliary storage device 1002 when a program startup command is received. The CPU 1004 implements the functions related to the memory device 1003 according to the program stored in the memory device 1003. The interface device 1005 is used as an interface for connecting to a network, etc. The display device 1006 displays a GUI (Graphical User Interface) etc. generated by a program. The input device 1007 consists of a keyboard and mouse, buttons, or a touch panel etc., and is used to input various operation commands. The output device 1008 outputs the calculation results.
[0190] It should be noted that the devices described in this embodiment (wiping and disinfection determination devices 100-103, and liquid spray determination device 700) are not limited to those implemented by having a computer execute a program. The devices may also be implemented as hardware, for example, by incorporating such hardware into a camera and providing it as a system.
[0191] In the description of this embodiment, the morphological characteristics of the cleaning tool were acquired using a physical camera to detect parts such as markers and LEDs, thereby obtaining the position of the cleaning tool. However, the position may also be obtained by extracting the cleaning tool from the physical camera image using image processing, or by using other position acquisition methods such as laser positioning. In that case, alignment between each position acquisition method and the thermal camera image will be necessary.
[0192] (Effects of the embodiment) As described above, the technology described in this embodiment makes it possible to determine the areas of a surface that have been successfully disinfected, even when the target is a stainless steel surface such as the work area of a safety cabinet, and as a result, it also becomes possible to determine the areas of a surface that have been successfully wiped and disinfected.
