Description

Technical Field

[0001] This utility model relates to the field of shelf handling, and in particular to a camera assembly and a stealthy shelf handling vehicle. Background Technology

[0002] Hidden-type automated guided vehicles (AGVs) for rack transport are typically equipped with an upward-facing camera and a supplementary light. The racks to be transported by the AGV have QR code labels affixed to their bottoms. Once the rack is supported on the AGV, the supplementary light is activated, and then the camera photographs and identifies the QR code labels on the rack's bottom. Because the space under the racks is narrow, natural light is difficult to penetrate; therefore, the supplementary light is essential for the camera to photograph and identify the QR code labels.

[0003] Furthermore, to prevent debris from falling into the AGV and damaging its internal transmission mechanisms, the AGV is typically equipped with a transparent protective cover. Correspondingly, some of the light emitted by the supplementary lighting needs to be transmitted through the protective cover to the QR code label, where it is then reflected back through the cover to the camera. Simultaneously, another portion of the light from the supplementary lighting is reflected directly back to the camera by the protective cover. When the light reflected from the protective cover and the light reflected from the QR code label meet at the camera, it results in poor image quality, hindering proper QR code recognition and reducing the accuracy and success rate of QR code recognition. Utility Model Content

[0004] Therefore, it is necessary to provide a camera component and a hidden shelf transport vehicle to address the problem that the accuracy of QR code recognition on shelves is difficult to meet when a hidden shelf transport AGV is equipped with a protective cover.

[0005] A shooting component, comprising:

[0006] Ultraviolet light source;

[0007] Imaging sensor;

[0008] A first transmissive plate, wherein the ultraviolet light source and the imaging sensor are located on the same side of the first transmissive plate, the first transmissive plate being used to transmit ultraviolet light emitted by the ultraviolet light source to a first pattern made of ultraviolet fluorescent material, and to allow visible light emitted by the first pattern to transmit to the imaging sensor; and

[0009] An ultraviolet cut-off filter is disposed between the imaging sensor and the first transmission plate.

[0010] In one embodiment, the imaging assembly further includes a lens barrel, the imaging sensor is located inside the lens barrel, the ultraviolet cut-off filter is disposed at the end of the lens barrel, and the ultraviolet light source is located outside the lens barrel.

[0011] A stealthy shelf transport vehicle includes a vehicle body and a camera assembly mounted on the vehicle body.

[0012] In one embodiment, the vehicle body includes a tray and a movable base. The tray is mounted on the movable base and has a light-transmitting opening. The first transmissive plate is mounted at the light-transmitting opening. The ultraviolet light source, the imaging sensor, and the ultraviolet cut-off filter are mounted on the movable base and located below the light-transmitting opening.

[0013] In one embodiment, the first pattern is disposed at the bottom of the shelf, which is supported on the vehicle body.

[0014] A shooting component, comprising:

[0015] Infrared light source;

[0016] Imaging sensor;

[0017] A second transmissive plate, wherein the infrared light source and the imaging sensor are located on the same side of the second transmissive plate, the second transmissive plate is used to transmit infrared light emitted by the infrared light source to a second pattern made of infrared fluorescent material, and to allow visible light emitted by the second pattern to transmit to the imaging sensor; and

[0018] An infrared cut-off filter is disposed between the imaging sensor and the second transmission plate.

[0019] In one embodiment, the imaging assembly further includes a lens barrel, the imaging sensor is located inside the lens barrel, the infrared cut-off filter is disposed at the end of the lens barrel, and the infrared light source is located outside the lens barrel.

[0020] A stealthy rack transport vehicle includes a vehicle body and a camera assembly mounted on the vehicle body.

[0021] In one embodiment, the vehicle body includes a tray and a movable base. The tray is mounted on the movable base and has a light-transmitting opening. The second transmissive plate is mounted at the light-transmitting opening. The infrared light source, the imaging sensor, and the infrared cut-off filter are mounted on the movable base and located below the light-transmitting opening.

[0022] In one embodiment, the second pattern is disposed at the bottom of the shelf, which is supported on the vehicle body.

[0023] In a first aspect of this invention, an ultraviolet light source serves as a supplementary light source. It first generates ultraviolet light that is directed towards a first transmissive plate. Upon reaching the first transmissive plate, part of the ultraviolet light is transmitted, and part is reflected. The ultraviolet light reflected from the first transmissive plate is blocked by an ultraviolet cut-off filter between the imaging sensor and the first transmissive plate, thereby reducing or preventing the imaging sensor from receiving ultraviolet light. The ultraviolet light transmitted through the first transmissive plate then targets a first pattern. The first pattern absorbs the ultraviolet light and generates visible light. This visible light sequentially passes through the first transmissive plate and the ultraviolet cut-off filter, ultimately reaching the imaging sensor and being received by it. The imaging sensor then uses the received visible light to capture and identify the first pattern.

[0024] Therefore, the imaging component provided by this utility model has the following advantages: First, the first transmissive plate allows ultraviolet light to be transmitted to the first pattern on the one hand, and visible light emitted by the first pattern to be transmitted to the imaging sensor on the other hand, thereby allowing the imaging sensor to scan and photograph the first pattern; Second, the first transmissive plate can shield the bottom of the shelf, thereby preventing debris falling from the bottom of the shelf from entering the vehicle body; Third, when the supplementary light is reflected at the first transmissive plate and goes to the imaging sensor, it will be blocked by the ultraviolet cut-off filter, so the imaging sensor will not receive ultraviolet light or will only receive a small amount of ultraviolet light. The imaging sensor will basically only receive visible light and perform imaging, thereby reducing the impact of the supplementary light reflection behavior on the imaging sensor's imaging quality; Fourth, since the supplementary light is ultraviolet light and the imaging light is visible light, there is a difference in their wavelengths. Therefore, even if the imaging sensor receives a small amount of supplementary light, it can easily distinguish it from the imaging light, which helps the imaging sensor eliminate the interference of supplementary light on the imaging process.

[0025] In a second aspect of this invention, an infrared light source serves as a supplementary light source. It first generates infrared light that is directed towards a second transmissive plate. Upon reaching the second transmissive plate, part of the infrared light is transmitted, and part is reflected. The infrared light reflected from the second transmissive plate is blocked by an infrared cut-off filter between the imaging sensor and the second transmissive plate when it reaches the imaging sensor, thereby reducing or preventing the imaging sensor from receiving infrared light. The infrared light transmitted through the second transmissive plate then reaches a second pattern. The second pattern absorbs the infrared light and generates visible light. This visible light passes through the second transmissive plate and the infrared cut-off filter in sequence, finally reaching the imaging sensor and being received by it. The imaging sensor then uses the received visible light to capture and identify the second pattern.

[0026] Therefore, the imaging component provided by this utility model has the following advantages: First, the second transmissive plate allows infrared light to be transmitted to the second pattern on the one hand, and visible light emitted by the second pattern to be transmitted to the imaging sensor on the other hand, thereby allowing the imaging sensor to scan and photograph the second pattern; Second, the second transmissive plate can shield the bottom of the shelf, thereby preventing debris falling from the bottom of the shelf from entering the vehicle body; Third, when the supplementary light is reflected at the second transmissive plate and goes to the imaging sensor, it will be blocked by the infrared cut-off filter, so the imaging sensor will not receive infrared light or will only receive a small amount of infrared light. The imaging sensor will basically only receive visible light and perform imaging, thereby reducing the impact of the supplementary light reflection behavior on the imaging sensor's imaging quality; Fourth, since the supplementary light is infrared light and the imaging light is visible light, there is a difference in their wavelengths. Therefore, even if the imaging sensor receives a small amount of supplementary light, it can easily distinguish it from the imaging light, which helps the imaging sensor eliminate the interference of supplementary light on the imaging process.

[0039] Example 1:

[0040] like Figure 1 and Figure 2 As shown, this embodiment of a concealed shelf transport vehicle includes a vehicle body 200 and a camera component mounted on the vehicle body 200. Furthermore, in this embodiment, a first pattern 100 is provided on the bottom of the shelf 300. When the shelf 300 is supported on the vehicle body 200, the camera component can scan and photograph the first pattern 100 to obtain information about the shelf 300.

[0041] It is particularly noteworthy that the first pattern 100 in this embodiment is made of ultraviolet fluorescent material. Therefore, when the first pattern 100 absorbs ultraviolet light, it will emit visible light. The specific composition, preparation method, and material properties of the ultraviolet fluorescent material are all existing technologies and will not be described in detail in this embodiment. The first pattern 100 may be, for example, a QR code or a barcode.

[0042] Specifically, the vehicle body 200 includes a tray 201 and a movable base 202. The tray 201 is mounted on the movable base 202, and the tray 201 can be raised, lowered, and rotated on top of the movable base 202. The connection and movement relationship between the tray 201 and the movable base 202 are existing technologies and will not be described in detail in this embodiment.

[0043] The imaging assembly includes an ultraviolet light source 1, an imaging sensor 2, a first transmissive plate 3, and an ultraviolet cut-off filter 4. A light-transmitting opening is provided on the tray 201, and the first transmissive plate 3 is mounted at the opening and blocks it; in this configuration, the first transmissive plate 3 is generally horizontal. The ultraviolet light source 1, the imaging sensor 2, and the ultraviolet cut-off filter 4 are located on the same side of the first transmissive plate 3 and are mounted on the movable base 202.

[0044] More specifically, in this embodiment, the ultraviolet light source 1, the imaging sensor 2, and the ultraviolet cut-off filter 4 are located below the first transmission plate 3. In other words, the ultraviolet light source 1, the imaging sensor 2, and the ultraviolet cut-off filter 4 are also located below the light-transmitting opening. The vehicle body 200 specifically supports the shelf 300 via the pallet 201. When the shelf 300 is supported on the pallet 201, the first pattern 100 is located above the first transmission plate 3.

[0045] By using the first transmission plate 3 to block the light-transmitting opening, on the one hand, it can effectively prevent debris falling from the shelf 300 from entering the movable base 202 through the light-transmitting opening, thereby protecting the transmission mechanism inside the movable base 202. On the other hand, it can effectively prevent human hands from entering the gap between the pallet 201 and the movable base 202 through the light-transmitting opening, thereby improving safety.

[0046] In this embodiment, the first transmissive plate 3 not only allows visible light to pass through, but also has a high transmittance for ultraviolet light. The specific material of the first transmissive plate 3 is existing technology and will not be described in detail in this embodiment. The ultraviolet cut-off filter 4 can block ultraviolet light while allowing visible light to pass through. The specific structure and material of the ultraviolet cut-off filter 4 are also existing technology and will not be described in detail in this embodiment.

[0047] The ultraviolet (UV) cut-off filter 4 is specifically disposed between the imaging sensor 2 and the first transmission plate 3. Accordingly, the UV cut-off filter 4 can block ultraviolet light between the imaging sensor 2 and the first transmission plate 3, while allowing visible light to pass through. It is important to note that the UV cut-off filter 4 needs to minimize obstruction of the space between the ultraviolet light source 1 and the first transmission plate 3 to avoid blocking the ultraviolet light between them.

[0048] The specific imaging process of the imaging component for the first pattern 100 in this embodiment is as follows: The ultraviolet light source 1 acts as a supplementary light, first generating ultraviolet light that shines onto the first transmission plate 3. Upon reaching the first transmission plate 3, part of the ultraviolet light is transmitted, and part is reflected. The ultraviolet light reflected from the first transmission plate 3 is blocked by the ultraviolet cut-off filter 4 between the imaging sensor 2 and the first transmission plate 3 when it reaches the imaging sensor 2, thereby reducing or preventing the imaging sensor 2 from receiving ultraviolet light. The ultraviolet light transmitted through the first transmission plate 3 then shines onto the first pattern 100. The first pattern 100 absorbs the ultraviolet light and generates visible light. This visible light passes through the first transmission plate 3 and the ultraviolet cut-off filter 4 in sequence, finally reaching the imaging sensor 2 and being received by it. The imaging sensor 2 then uses the received visible light to capture and identify the first pattern 100.

[0049] In summary, the imaging component of this embodiment has the following advantages: First, the first transmissive plate 3 effectively improves safety by blocking the light-transmitting port and the bottom of the shelf 300; second, the reflected light from the first transmissive plate 3 is blocked by the ultraviolet cut-off filter 4 on its way to the imaging sensor 2, so the imaging sensor 2 does not receive ultraviolet light, or only receives a small amount of ultraviolet light. Therefore, the imaging sensor 2 can perform imaging almost entirely based on visible light. In other words, the negative impact of the reflection behavior of the supplementary light at the first transmissive plate 3 on the imaging quality of the imaging sensor 2 is effectively suppressed in this embodiment; in addition, since the supplementary light is ultraviolet light and the imaging light is visible light, there is a difference in their wavelengths. Therefore, even if the imaging sensor 2 receives a small amount of supplementary light, it can easily distinguish it from the imaging light, which helps the imaging sensor eliminate the interference of the supplementary light on the imaging process.

[0050] Preferably, the imaging assembly in this embodiment also includes a lens barrel 5, with the imaging sensor 2 located inside the lens barrel 5, an ultraviolet cut-off filter 4 disposed at the end of the lens barrel 5, and an ultraviolet light source 1 located outside the lens barrel 5. By blocking ultraviolet light through the lens barrel 5, the ultraviolet light source 1 can be prevented from directly shining ultraviolet light onto the imaging sensor 2.

[0051] Example 2:

[0052] like Figure 3 and Figure 4 As shown, this embodiment of a concealed shelf transport vehicle includes a vehicle body 200 and a camera component mounted on the vehicle body 200. Furthermore, in this embodiment, a second pattern 400 is provided at the bottom of the shelf 300. When the shelf 300 is supported on the vehicle body 200, the camera component can scan and photograph the second pattern 400 to obtain information about the shelf 300.

[0053] It is particularly noteworthy that the second pattern 400 in this embodiment is made of infrared fluorescent material. Therefore, when the second pattern 400 absorbs infrared light, it will emit visible light. The specific composition, preparation method, and material properties of the infrared fluorescent material are existing technologies and will not be described in detail in this embodiment. The second pattern 400 can be, for example, a QR code or a barcode.

[0054] Specifically, the vehicle body 200 includes a tray 201 and a movable base 202. The tray 201 is mounted on the movable base 202, and the tray 201 can be raised, lowered, and rotated on top of the movable base 202. The connection and movement relationship between the tray 201 and the movable base 202 are existing technologies and will not be described in detail in this embodiment.

[0055] The imaging assembly includes an infrared light source 6, an imaging sensor 2, a second transmissive plate 7, and an infrared cut-off filter 8. A light-transmitting opening is provided on the tray 201, and the second transmissive plate 7 is mounted at the opening and blocks it; in this configuration, the second transmissive plate 7 is generally horizontal. The infrared light source 6, the imaging sensor 2, and the infrared cut-off filter 8 are located on the same side of the second transmissive plate 7 and are mounted on the movable base 202.

[0056] More specifically, in this embodiment, the infrared light source 6, the imaging sensor 2, and the infrared cut-off filter 8 are located below the second transmission plate 7. In other words, the infrared light source 6, the imaging sensor 2, and the infrared cut-off filter 8 are also located below the light-transmitting opening. The vehicle body 200 specifically supports the shelf 300 via the pallet 201. When the shelf 300 is supported on the pallet 201, the second pattern 400 is located above the second transmission plate 7.

[0057] By using the second transmission plate 7 to block the light-transmitting opening, on the one hand, it can effectively prevent debris falling from the shelf 300 from entering the movable base 202 through the light-transmitting opening, thereby protecting the transmission mechanism inside the movable base 202. On the other hand, it can effectively prevent people's hands from entering the gap between the pallet 201 and the movable base 202 through the light-transmitting opening, thereby improving safety.

[0058] In this embodiment, the second transmissive plate 7 not only allows visible light to pass through, but also has high transmittance for infrared light. The specific material of the second transmissive plate 7 is existing technology and will not be described further in this embodiment. The infrared cut-off filter 8 can block infrared light while still allowing visible light to pass through. The specific structure and material of the infrared cut-off filter 8 are also existing technology and will not be described further in this embodiment.

[0059] An infrared cut-off filter 8 is specifically disposed between the imaging sensor 2 and the second transmission plate 7. Accordingly, the infrared cut-off filter 8 can block infrared light between the imaging sensor 2 and the second transmission plate 7, while allowing visible light to pass through. It is important to note that the infrared cut-off filter 8 needs to minimize obstruction of the space between the infrared light source 6 and the second transmission plate 7 to avoid blocking the infrared light between them.

[0060] The specific imaging process of the imaging component for the second pattern 400 in this embodiment is as follows: The infrared light source 6 acts as a supplementary light, first generating infrared light that is directed towards the second transmission plate 7. Upon reaching the second transmission plate 7, part of the infrared light is transmitted, and part is reflected. The infrared light reflected from the second transmission plate 7 is blocked by the infrared cut-off filter 8 between the imaging sensor 2 and the second transmission plate 7 when it reaches the imaging sensor 2, thereby reducing or preventing the imaging sensor 2 from receiving infrared light. The infrared light transmitted through the second transmission plate 7 then reaches the second pattern 400. The second pattern 400 absorbs the infrared light and generates visible light. This visible light sequentially passes through the second transmission plate 7 and the infrared cut-off filter 8, finally reaching the imaging sensor 2 and being received by it. The imaging sensor 2 then uses the received visible light to capture and identify the second pattern 400.

[0061] In summary, the imaging component of this embodiment has the following advantages: First, the second transmission plate 7 effectively improves safety by blocking the light-transmitting port and the bottom of the shelf 300; second, the reflected light from the supplementary light at the second transmission plate 7 is blocked by the infrared cut-off filter 8 on its way to the imaging sensor 2, so the imaging sensor 2 does not receive infrared light, or only receives a small amount of infrared light. Therefore, the imaging sensor 2 can perform imaging almost entirely based on visible light. In other words, the negative impact of the reflection behavior of the supplementary light at the second transmission plate 7 on the imaging quality of the imaging sensor 2 is effectively suppressed in this embodiment; in addition, since the supplementary light is infrared light and the imaging light is visible light, there is a difference in their wavelengths. Therefore, even if the imaging sensor 2 receives a small amount of supplementary light, it can easily distinguish it from the imaging light, which helps the imaging sensor eliminate the interference of the supplementary light on the imaging process.

[0062] Preferably, the imaging assembly in this embodiment also includes a lens barrel 5, with the imaging sensor 2 located inside the lens barrel 5, an infrared cut-off filter 8 disposed at the end of the lens barrel 5, and an infrared light source 6 located outside the lens barrel 5. By blocking infrared light through the lens barrel 5, the infrared light source 6 can be prevented from directly shining infrared light onto the imaging sensor 2.

[0063] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
