Description

Technical Field

[0001] This disclosure relates to the field of image acquisition technology, and more particularly to an imaging device. Background Technology

[0002] Fire is an unavoidable disaster in social production activities, especially in urban buildings. Due to the limited indoor space, flames can fill the entire room, and the brightness of the flames makes it impossible for firefighters to observe the specific situation inside the room.

[0003] The intense light, heat, and smoke of flames render ordinary visible light cameras ineffective, and images captured by conventional cameras are distorted by the intense firelight, resulting in information loss and hindering rescue efforts. While traditional infrared cameras can provide thermal images to some extent, their operation relies on the reflection or radiation of heat sources. However, at a fire scene, the heat emitted by the flames themselves often causes infrared camera images to be distorted or fail to accurately capture detailed information about areas covered by flames. Whether using visible light, infrared imaging technology, or other traditional methods, existing equipment cannot penetrate flames and smoke to directly obtain clear images of areas behind the fire source and those obscured by it.

[0004] Therefore, there is a need for a device that can be applied to fire scenarios and can penetrate and image through flames and smoke. Utility Model Content

Detailed Implementation

[0047] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0048] Figure 1 This is a schematic diagram of the structure of an imaging device provided in an embodiment of this disclosure; as shown below. Figure 1 As shown, the device includes: a housing, an imaging component, a display component, and a power supply component; the power supply component is used to supply power to the imaging component and the display component;

[0049] The imaging components include: a laser light source device, a lens, an image sensor, and an imaging circuit;

[0050] The display component includes: a display driving circuit and a display screen;

[0051] The imaging component, the display driving circuit, and the power supply group are disposed within the housing; the housing has a lens hole, a laser hole, and a display hole, the display hole being used to house the display screen, the lens hole being provided with glass, and the laser hole being used to house the laser emitting end of the laser source device; the laser source device is disposed on one side of the lens; the imaging circuit is electrically connected to the image sensor and the display driving circuit respectively.

[0052] It should be noted that, Figure 1 The laser aperture, display aperture, and lens aperture shown are merely examples of aperture placement and do not represent the size relationship between them. Furthermore, the placement of the laser aperture and lens aperture is only to illustrate that they are located on the same surface. Figure 1 The hole position setting does not necessarily indicate that the laser hole and the lens hole are in an up-down relationship.

[0053] Specifically, the housing is the external frame of the imaging device, which can be used to protect, support, or install the required components.

[0054] The imaging component is used to capture and process portions of an image. The display component is used to display the acquired image data to the user. The power supply component provides power to ensure that the imaging component and the display component can function properly.

[0055] Specifically, the lens aperture is an opening designed for the lens, through which light enters, is captured by the lens, and processed to form an image. A glass pane is installed within the lens aperture to prevent dust from entering; this glass is made of a high-temperature resistant material for protection. The lens aperture uses a slot design, allowing the glass to be fixed within the aperture, and it can be removed and reinstalled if needed. The laser source device is located on one side of the lens, and correspondingly, the laser aperture is located on one side of the lens aperture to ensure that the laser emitted by the laser source device can be emitted, reflected, and illuminate the area focused by the lens. The display aperture is an opening designed for the display screen, through which the display outputs the image.

[0056] Specifically, the lens can be used to focus or adjust light, including reflected laser light.

[0057] The image sensor can be used to capture light transmitted from the lens and convert it into a digital signal, which is then transmitted to the imaging circuit for processing.

[0058] The imaging circuit can be used to drive the laser source device to emit laser light; process signals from the image sensor to obtain image data; and store the image data and transmit the image data to a connected display driver circuit, etc.

[0059] The display driving circuit can be used to receive image data from the imaging circuit and control the display screen to display the image data.

[0060] Here, the lens, image sensor, imaging circuit, and display driving circuit can be of any type and circuit structure, as long as they achieve the above functions. For example, the lens can be a lens with AF (Auto Focus) and OIS (Optical Image Stabilization) functions, which is fixed in the housing by a lens holder. The image sensor can be a laser image sensor, such as a LiDAR (Light Detection and Ranging) sensor or a TOF (Time-of-Flight) sensor. The imaging circuit may include an analog-to-digital converter (ADC), memory, image signal processor (ISP), clock and synchronization circuits, etc. The display driving circuit may include a display driver IC (TFT driver chip), a voltage converter (DC-DC converter), etc. There are no limitations on the circuit structure or the types of components used.

[0061] Here, the imaging circuit and the display driving circuit are disposed on a first circuit board, which is located below or behind the lens; or, the imaging circuit is disposed on a second circuit board, and the display driving circuit is disposed on a third circuit board, with the second circuit board and the third circuit board being electrically connected; the second circuit board and the third circuit board are located below or behind the lens.

[0062] The imaging circuit and the display driving circuit can be located on the same circuit board (such as the first circuit board) or on different circuit boards (such as the second and third circuit boards). Taking the example of them being located on different circuit boards, the image sensor can also be located on the second circuit board or be electrically connected to the second circuit board. The second circuit board and the third circuit board can be placed in parallel to save space.

[0063] It should be noted that the imaging circuit is electrically connected to the image sensor and the display driving circuit, so that the image sensor captures signals and transmits the signals to the imaging circuit for processing. The processed image data is then transmitted to the display driving circuit and finally displayed to the user through the display screen.

[0064] like Figure 2 The diagram shows an imaging component and a display component. The second circuit board and the third circuit board are electrically connected. The second circuit board and the third circuit board are located behind the image sensor and are placed in parallel. An imaging circuit is arranged on the second circuit board, and a display driving circuit is arranged on the third circuit board.

[0065] This provides an application example. Assume the imaging device is powered on, and the power supply component powers the imaging and display components to ensure their proper functioning. The imaging circuit works synchronously with the laser source device. The imaging circuit drives the laser source device to emit laser light (e.g., a narrow-band pulsed laser). The laser light penetrates the flame and illuminates the surface of objects behind it (e.g., walls, floors, tables, chairs, etc.), then reflects back and penetrates the flame again to enter the lens (utilizing the laser's wavelength and energy, which are sufficient to penetrate the flame). Simultaneously, the lens captures the intense light from the flame in the scene. The laser light and the captured intense light from the flame enter the lens's optical path together. The image sensor converts the collected light (e.g., laser light, intense flame light) into electrical signals, and the imaging circuit generates image data based on these signals. Here, the timing of the laser light emission driven by the imaging circuit is synchronized with the imaging circuit's exposure time. That is, the imaging circuit can control the laser emission based on the exposure time (i.e., the length of time the lens is exposed to light) to obtain a clear image.

[0066] In some embodiments, considering that the intense light from flames can have an adverse effect on imaging, this disclosure also provides a method for filtering out the intense light from flames.

[0067] Based on this, the device further includes: a filter device;

[0068] The filtering device includes at least one filter, which is disposed in front of the lens and / or between the lens and the image sensor.

[0069] In one example, the number of the filter is one, which is positioned directly in front of the lens to filter out the light to be captured by the lens, such as... Figure 3 The diagram shows a schematic of a filter setup.

[0070] In another example, there are two filters, such as a first filter and a second filter; the first filter is positioned directly in front of the lens, and the second filter is positioned directly behind the lens (specifically, between the lens and the image sensor), as shown below. Figure 4 As shown, a schematic diagram of a multi-filter setup is provided. In this way, the light to be captured by the lens can be filtered twice by the first filter and the second filter, so as to filter out light (such as strong flame light) outside the wavelength range of the laser light source device as much as possible. Thus, the final imaging effect of the imaging device can achieve the effect of filtering out strong flame light.

[0071] It should be noted that the number of filters can also be N, where N is greater than 2. When N is greater than 2, multiple filters can be stacked and located directly in front of the lens and / or between the lens and the image sensor. Furthermore, the choice of the number N can be based on the required filtering effect and final imaging effect. For example, during product design, the filtering effect and final imaging effect can be measured to select appropriate filters and their quantity; therefore, the quantity is not limited here.

[0072] In some embodiments, the filter is a narrowband filter;

[0073] The laser emitted by the laser source device is a narrowband pulsed laser;

[0074] The center wavelength of the filter is the same as the center wavelength of the laser emitted by the laser source device.

[0075] Here, the function of a filter is to selectively allow light within a specific wavelength range to pass through while blocking other wavelengths. The term "narrow band" refers to the fact that the filter allows a very narrow range of wavelengths of light to pass through, typically limited to a specific wavelength. Therefore, it can be understood that the filter only allows light within a certain range to pass through, while other wavelengths are blocked, to ensure the accuracy and clarity of the image or light source.

[0076] The laser emitted by the laser source device is a narrowband pulsed laser, that is, its wavelength range is very narrow, which makes the laser beam highly monochromatic.

[0077] Pulsed lasers mean that lasers are not emitted continuously, but periodically in the form of pulses, which can be used in scenarios requiring high precision or short-duration laser irradiation.

[0078] Here, the center wavelength of the filter is consistent with the center wavelength of the laser emitted by the laser source device. This means that the wavelength of the filter (i.e., the wavelength through which it transmits most strongly) is perfectly matched with the wavelength emitted by the laser source, thereby ensuring that the filter can accurately transmit the light emitted by the laser without losing any important laser information or affecting the laser effect.

[0079] In this way, by selectively allowing narrowband light that matches the laser wavelength to pass through the filter, the laser beam emitted by the laser source can be ensured that it is not interfered with by unnecessary wavelength light when passing through the filter, thereby improving the accuracy and effect of the final imaging.

[0080] In some embodiments, the center wavelength of the laser is one of the following: 808nm, 905nm, 940nm, or 980nm.

[0081] Here, depending on the specific application requirements, any of the wavelengths mentioned above can be used for the laser. Of course, other wavelengths applicable to fields such as medical, communications, and laser ranging can also be used for the laser; no limitation is made here.

[0082] In some embodiments, the laser source device includes at least one laser emitter, and the number of laser holes is the same as the number of laser emitters; each laser emitter is disposed on one side of the lens.

[0083] Here, the laser emitter is a sheet-shaped laser emitter; the sheet-shaped laser emitter is a vertical cavity surface emitter (VCSEL).

[0084] In one example, the number of laser emitters is one, which is located on any side of the lens; for example, it can be located on the top, bottom, left, or right side of the lens. Figure 5 The image shows a frontal view of a laser emitter positioned to the left of the lens.

[0085] In another example, the number of laser emitters is two, assuming they are a first laser emitter and a second laser emitter; as shown... Figure 6 As shown, the first laser emitter and the second laser emitter are located on the left and right sides of the lens, respectively. Of course, they can also be located at the top and bottom, upper left, lower right, etc. of the lens.

[0086] In some embodiments, the power supply component includes a storage battery for powering the imaging component and the display component.

[0087] Here, the contact battery may include one or more batteries. The power supply component can be of any structure or form to power the imaging component and display component, and its size can be installed in the housing. There is no limitation on the specific structure used. For example, the power supply component may also include power management circuitry.

[0088] In some embodiments, the device further includes: a connection component and a portable display component;

[0089] The connection component includes at least one of the following:

[0090] An interface and connecting cable, wherein the interface is electrically connected to the imaging circuit;

[0091] A wireless transmission circuit, which is electrically connected to the imaging circuit;

[0092] The portable display component is used to receive image data transmitted by the imaging circuit through the interface and the connecting cable; and / or, to receive image data transmitted by the imaging circuit through the wireless transmission circuit.

[0093] Both wired and wireless connections are available here.

[0094] Wired connection: The portable display component can be connected to the imaging circuit via an interface and a connecting cable. That is, the imaging circuit communicates with the display component through a physical connection. The portable display component can receive image data from the imaging circuit and present the image data to the user through the portable display component.

[0095] Wireless connectivity: The portable display component can also be connected to the imaging circuit via a wireless transmission circuit, meaning that no physical cable is required. The signal is transmitted wirelessly, and the portable display component can also receive image data from the imaging circuit and present the image data to the user through the portable display component.

[0096] In some embodiments, the number of the portable display components is at least one;

[0097] The portable display component includes at least one of the following: a head-mounted display, a virtual reality helmet, a headphone display device, smart glasses, a wearable display device, and a fireproof face shield with smart glasses.

[0098] Specifically, a head-mounted display is a device similar to glasses with a built-in display screen that allows users to view content by wearing it.

[0099] Smart glasses, similar to head-mounted displays, project content in front of the user's eyes. For example... Figure 7 The diagram shows a smart glasses solution that can be connected to the imaging circuit via a connecting cable.

[0100] Considering that imaging devices can be applied to firefighters at fire scenes, portable display components can also be fireproof masks with smart glasses. These masks integrate the traditional protective functions of protective masks (using highly heat-resistant and fireproof materials to effectively isolate flames and high temperatures) with the image display technology of smart glasses (such as displaying important information in the wearer's field of vision, such as the location of the fire source, escape routes, and the location of surrounding people), enabling firefighters to better respond to fires and other emergencies in fire scenarios.

[0101] A virtual reality headset is a display device that uses augmented reality (AR) technology. When a user wears it, they can see augmented reality images superimposed on a view of the real world.

[0102] A headphone display device is a device that integrates headphone and display functions. That is, it not only provides audio functions but also has a display screen. For image data, it can describe through audio and / or present images through the display screen.

[0103] Wearable display devices such as smartwatches and smart bracelets can also be used as part of portable display components.

[0104] It should be noted that the selection of the above portable display components can be based on the needs of the application scenario.

[0105] In some embodiments, the housing may take the shape of one of the following: a handheld shape, a cube shape, a cylindrical shape, or a helmet shape.

[0106] In one example, a handheld housing with a handle is used to allow the user to easily hold the device for shooting. Furthermore, a component mounting section is located on top of the handle, housing the imaging assembly, display assembly, and power supply assembly. Alternatively, the handle section can be hollowed out, allowing components such as the power supply assembly to be housed within the handle, thus saving space in the component mounting section.

[0107] like Figure 8The diagram shows a cross-sectional view of an imaging device with a handheld housing. The handle portion of the housing 1 is hollow, housing a battery 13. Above the handle is a component mounting section, which includes a first laser emitter 3, a second laser emitter 4, a first filter 5, a second filter 7, a lens 6, an image sensor 8, an imaging circuit 9, a wireless transmission circuit 10, a display driving circuit 11, and a display screen 12. The first filter 5 and the second filter 7 are located directly in front of and behind the lens 6, respectively. The housing portion corresponding to the lens 6 has a lens aperture, which is fitted with a protective glass window 2. The display screen 12 is located on the opposite side from the lens aperture, allowing the user to view images. The imaging circuit 9, the wireless transmission circuit 10, and the display driving circuit 11 can be placed parallel to each other behind the lens 6, and are electrically connected to each other.

[0108] like Figure 9 and 10 As shown, a rear view and a side view of an imaging device with a handheld housing are provided. The housing 1 includes a handle portion 21 and a device mounting portion 22 disposed above the handle. The user can view the captured images by holding the imaging device through the display screen 12.

[0109] like Figure 11 As shown, a side view of another imaging device with a handheld housing is provided. The housing 1 includes a handle portion 21 and a device mounting portion 22 disposed above the handle. The imaging device uses two laser emitters, namely a first laser emitter 3 and a second laser emitter 4, and takes pictures in conjunction with a lens 6.

[0110] It should be understood that, in order to house the laser emitter, lens, filter, circuit board and other components, the housing 1 may also contain related mounting components. The mounting components are related to the number of each component and the required placement location, and there are no limitations on the mounting components.

[0111] In another example, a cubic shell, which can be square or rectangular, can be used, resembling a typical camera, camcorder, or monitor. This design is compact, making it easy to store and carry. This shape can be designed with mounting holes, allowing accessories to be carried or secured via these holes, thus enhancing the portability and flexibility of the imaging device.

[0112] In another example, a cylindrical (or tubular) housing is used, which can resemble the appearance of an action camera. Similar to a cubic housing, this shape can be designed with mounting holes to facilitate carrying or securing the imaging device with accessories.

[0113] In another example, a helmet-shaped shell is used; the imaging device's casing includes a dedicated helmet designed to be secured to the user's head. The top of the helmet features a mounting area, such as a device mounting section, where the imaging components, display components, and power supply components are housed. This design allows the imaging device to be securely mounted on the helmet, ensuring stability and clarity during image capture. The helmet's design also allows for easy operation and first-person perspective images, making it convenient and portable.

[0114] It should be noted that the casing of the imaging device can also be in other shapes, providing users with a convenient, fast, and flexible shooting experience.

[0115] In some embodiments, the housing is made of silicone rubber composite material; the glass is made of K9 optical glass.

[0116] Here, in order to achieve image acquisition at the fire scene, the shell is made of silicone rubber composite material because it has good high temperature resistance. It can usually be used for a long time at high temperatures without losing its elasticity. The high temperature resistance range is generally -50°C to 250°C. Of course, high-performance silicone rubber can also be used to withstand higher temperatures.

[0117] K9 optical glass is a type of glass material used in lenses, optical instruments, and display devices. K9 optical glass also has relatively good high-temperature resistance, so it is not easily deformed or damaged in environments with large temperature variations.

[0118] The imaging device disclosed herein emits a laser through a laser light source device and captures the light from the laser and the flame together through a lens. It relies on the penetrability of the laser to obtain information about objects behind the flame, and at the same time uses a filter to process the strong light of the flame itself to obtain the objects behind the flame.

[0119] At fire scenes, the intense light from flames often makes it difficult for firefighters to accurately assess the situation inside a room. However, the fire-penetrating imaging technology of this disclosed imaging device can clearly display areas obscured by flames, thereby helping firefighters make quick decisions in complex environments.

[0120] Furthermore, the imaging device uses high-temperature resistant materials, making it suitable not only for fire scenes but also for other high-temperature, high-pressure, and low-visibility environments, such as chemical accidents and natural disasters, demonstrating strong versatility and adaptability.

[0121] In one example, the imaging device provided by the device at the fire scene can provide real-time images through the flames, allowing rescue personnel to see the specific situation behind the flames. For example, in a room full of flames, the spatial layout, the location of doors and windows, the placement of items, and whether there are trapped people inside can be seen through the flames, providing real-time image judgment for fire fighting and rescue operations.

[0122] In another example, the imaging device is applied to special fire rescue equipment, which can provide real-time image data for remote visual control through flame imaging.
