Abstract
Description
Technical Field
[0001] This disclosure relates to a monitoring device. Background Technology
[0002] As the public increasingly values the quality and safety of their living environment, surveillance devices are frequently used to reduce blind spots in various locations. Typical surveillance devices have recording (image extraction) capabilities. Currently, there are wide-angle panoramic surveillance devices that use a single lens module with a rotating base to extract images from different spaces. However, the time difference during lens module rotation can create blind spots. Therefore, there are also surveillance devices composed of multiple lens modules, such as 360-degree fisheye surveillance devices, which extract images from different spaces to directly present multiple images from different spaces, or stitch multiple images together into a single image through image processing.
[0003] Commonly known multi-lens surveillance devices are typically hemispherical or similar curved spheres, mounted high up using a top-mounted mounting system. The multiple lenses are tilted downwards and outwards to capture images from different angles. However, this structure still results in some blind spots between the multiple images captured. Furthermore, in low-light conditions, the edges of the images captured by the lens modules tend to be blurry, making it difficult to stitch them together into a complete picture, thus still creating visual blind spots. Utility Model Content
[0004] In view of the above-mentioned problems, the main objective of this disclosure is to provide a monitoring device comprising a main body, a lens module, multiple sets of infrared emitting units, a photosensitive sensor, and a controller. Through the structure of the main body and the arrangement of the multiple sets of infrared emitting units, the lens module, the photosensitive sensor, and the controller, the problem of blind spots easily generated by the structure of known monitoring devices is solved.
[0005] To achieve the above objectives, this disclosure provides a monitoring device, comprising a main body, a lens module, multiple sets of infrared emitting units, a photosensor, and a controller. The main body includes four side walls and a top surface, with the top surface connected to the four side walls. The lens module includes four lenses, each disposed on one of the four side walls. The lens module is used to monitor an environment. The multiple sets of infrared emitting units provide infrared light. The multiple sets of infrared emitting units include a first set and a second set.

[0040] To better understand the technical content of this disclosure, preferred embodiments are described below.
[0041] Figure 1This is a schematic diagram of a monitoring device according to an embodiment of the present disclosure. Figure 2 for Figure 1 A partially exploded view of the monitoring device shown. Figure 3 for Figure 1 The top view of the monitoring device shown. Figure 4 for Figure 1 The diagram shows the internal structure of the monitoring device. Please refer to it. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the monitoring device 1 in this embodiment includes a main body 10, a lens module 20, multiple infrared light-emitting units 30, a photosensor 40, and a controller 50 (e.g., ...). Figure 4 (As shown). The controller 50 is electrically connected to the lens module 20, multiple sets of infrared light-emitting units 30, and the photosensor 40. The body 10 includes four side walls 11 and a top surface 12. The top surface 12 is connected to the four side walls 11 to form a quadrilateral prism. The lens module 20 is used to monitor an environment to acquire images of that environment at various points in time. Furthermore, the lens module 20 in this embodiment includes four lenses 21, which are respectively disposed on the four side walls 11, as shown... Figure 3 As shown. In other words, each side wall 11 is equipped with a lens 21, thereby acquiring images in all directions—east, west, south, and north—which facilitates subsequent image stitching and avoids blind spots. Specifically, four lenses 21 are installed on the four side walls 11 of the quadrilateral prism to acquire an east-facing image, a west-facing image, a south-facing image, and a north-facing image, and transmit them to the controller 50. Subsequently, the controller 50 can stitch the east-facing image, west-facing image, south-facing image, and north-facing image to generate an omnidirectional image, thereby avoiding blind spots.
[0042] like Figure 2 and Figure 3 As shown, the monitoring device 1 in this embodiment includes a first group of infrared emitting units 31 and a second group of infrared emitting units 32. The first group of infrared emitting units 31 is disposed on the top surface 12 of the main body 10, as shown in the figure. Figure 3 As shown. The second group of infrared emitting units 32 is disposed on the side wall 11 of the main body 10, as shown. Figure 2 As shown. In other words, in this embodiment, the plurality of infrared light-emitting units 30 disposed on the top surface 12 are referred to as the first group of infrared light-emitting units 31, and the plurality of infrared light-emitting units 30 disposed on the side wall 11 are referred to as the second group of infrared light-emitting units 32. Figure 2As shown, the infrared light-emitting units 30 of the second group of infrared light-emitting units 32 are respectively disposed on the four side walls 11, and the infrared light-emitting units 30 are adjacent to the four lenses 21. That is, multiple infrared light-emitting units 30 are respectively disposed around the outer periphery of the lens 21. Preferably, the infrared light-emitting units 30 surround the outer periphery of the lens 21. For example, eight infrared light-emitting units 30 surround the outer periphery of the lens 21 with the lens 21 as the center. The infrared light-emitting units 30 are used to provide infrared light, which can be, for example, infrared light-emitting diodes (IR LEDs). By arranging the infrared light-emitting units 30, the function of supplementing ambient light can be achieved when the ambient light is insufficient.
[0043] like Figure 3 As shown, in this embodiment, the photosensor 40 is disposed on the body 10. Preferably, in this embodiment, the photosensor 40 is disposed on the top surface 12 of the body 10. Furthermore, the photosensor 40 is used to sense ambient light and is electrically connected to the controller 50. In this embodiment, the monitoring device 1 preferably also includes a circuit board 60, and the controller 50 is disposed on the circuit board 60, as shown below. Figure 4 As shown. In this embodiment, the lens module 20, the infrared light-emitting unit 30, and the photosensor 40 are electrically connected to the controller 50 via the circuit board 60. For example, the lens module 20, the infrared light-emitting unit 30, the photosensor 40, and the circuit board 60 are connected by a flexible circuit board, and then electrically connected to the controller 50 disposed on the circuit board 60.
[0044] The photosensor 40 is a photosensitive element used to detect ambient light, which may be, for example, but not limited to, an ambient light sensor (ALS). The photosensor 40 detects the amount of ambient light to obtain photosensitivity parameters, which are then transmitted to the controller 50. The controller 50 can activate or deactivate the infrared emitting unit 30 based on the ambient light to supplement ambient light. For example, when the photosensitivity parameters are less than or equal to a preset value, the controller 50 determines that the ambient light is insufficient and activates the infrared emitting unit 30 to emit infrared light, thus supplementing ambient light. Therefore, even in insufficient ambient light conditions, the infrared emitting unit 30 can provide supplementary lighting to obtain a clear night vision image. Conversely, when the photosensitivity parameters are greater than the preset value, the controller 50 determines that the ambient light is sufficient and deactivates the infrared emitting unit 30.
[0045] Furthermore, since the infrared light-emitting units 30 of the second group of infrared light-emitting units 32 in this embodiment are arranged around the four lenses 21, an omnidirectional supplementary lighting effect is achieved, and the problem of blind spots at the edges of the image due to insufficient light can be avoided. In addition, the infrared light-emitting units 30 of the first group of infrared light-emitting units 31 are arranged on the top surface 12 of the body 10, which further avoids the problem of shadows or blurriness in the corners of the image due to insufficient light.
[0046] Preferably, the main body 10 of this embodiment includes a first housing 13 and a second housing 14 connected to each other. The lens module 20, the infrared light-emitting unit 30, and the photosensor 40 are disposed in the first housing 13, while the controller 50 and the circuit board 60 are disposed in the second housing 14. Figure 4 As shown. Specifically, both the first housing 13 and the second housing 14 are quadrilateral prisms, forming a quadrilateral prism. The volume of the second housing 14 is larger than that of the first housing 13. Lenses 21 are respectively disposed on the four side walls 11 of the quadrilateral prism; in this embodiment, they are disposed on the four side walls 11 of the first housing 13. Infrared light-emitting units 30 are respectively disposed on the four side walls 11 and the top surface 12 of the first housing 13, and a photosensor 40 is disposed on the top surface 12 of the first housing 13. The controller 50 and the circuit board 60 are disposed inside the second housing 14. When the monitoring device 1 of this embodiment is installed, the second housing 14 can be placed on a wall or ceiling, so that the first housing 13 and the top surface 12 face the ambient space. Since the photosensor 40 is disposed on the top surface 12 of the first housing 13, facing the ambient space, it can effectively detect ambient light to obtain more accurate photosensitivity parameters.
[0047] Preferably, the body 10 of this embodiment also includes a plurality of cover plates 15, respectively disposed on the four side walls 11 and the top surface 12, for covering the infrared light-emitting unit 30. It should be noted that... Figure 3 Remove the cover plate 15 located on the top surface 12 to reveal the infrared light-emitting unit 30 and the photosensor 40 located on the top surface 12. In this embodiment, the cover plate 15 located on the side wall 11 also includes an opening 151 and a light-transmitting portion 152. The opening 151 corresponds to the lens 21 and is used to expose the lens 21. That is, the lens 21 of the lens module 20 can pass through the opening 151. The cover plate 15 covers the infrared light-emitting unit 30, but the infrared light emitted by the infrared light-emitting unit 30 can still pass through the light-transmitting portion 152 of the cover plate 15.
[0048] In addition, the body 10 of this embodiment also includes a plurality of infrared light-transmitting ink layers 16, which are located on the outer surface of the cover plate 15 on the top surface 12 and on the outer surface of the cover plate 15 on the side wall 11. In other words, the infrared light-transmitting ink layer 16 is disposed on the outer surface of the cover plate 15. In one embodiment, the infrared light-transmitting ink can be directly coated on the outer surface of the cover plate 15 to form the infrared light-transmitting ink layer 16. In one embodiment, the infrared light-transmitting ink can be coated on a film or plate first, and then the film or plate coated with the infrared light-transmitting ink can be disposed on the outer surface of the cover plate 15 to form the infrared light-transmitting ink layer 16. The infrared light-transmitting ink layer 16 located on the side wall 11 also has an opening 161, which corresponds to the position of the lens 21, so that the lens 21 can pass through the openings 151 and 161 simultaneously.
[0049] The infrared light emitted by the infrared emitting unit 30 can still pass through the cover plate 15 and the infrared light-transmitting ink layer 16, thus still achieving the aforementioned function of supplementing ambient light. Simultaneously, the infrared light-transmitting ink layer 16 can visually conceal the structure of the infrared emitting unit 30, resulting in a consistent and aesthetically pleasing appearance for the monitoring device 1. In this embodiment, both the infrared light-transmitting ink layer 16 and the cover plate 15 are quadrilaterals. In other embodiments, the shape of the infrared light-transmitting ink layer 16 may correspond only to the light-transmitting portion 152 of the cover plate 15. That is, the infrared light-transmitting ink layer 16 can also be annular; this invention is not limiting.
[0050] Because the lens 21 in this embodiment is not disposed on the top surface 12, the infrared light-transmitting ink layer 16 located on the top surface 12 may not have an opening 161. In other embodiments, the lens 21 may also be disposed on the top surface 12, and the infrared light-transmitting ink layer 16 located on the top surface 12 may correspondingly have an opening 161; this invention is not limited. It should also be noted that... Figure 3 The infrared light-transmitting ink layer 16 is also removed from the top surface 12 of the body 10 shown, thereby revealing the infrared light-emitting unit 30 and the photosensitive sensor 40 located on the top surface 12.
[0051] In summary, the monitoring device disclosed herein includes a main body, a lens module, multiple sets of infrared emitting units, a photosensor, and a controller. The photosensor is used to sense ambient light. The controller is electrically connected to the lens module, the infrared emitting units, and the photosensor. Furthermore, the controller can activate or deactivate the infrared emitting units according to the ambient light to provide supplemental lighting. The four lenses of the lens module are respectively disposed on the four side walls of the main body, thereby acquiring images in all directions (east, west, south, and north), which is beneficial for subsequent image stitching. Additionally, the infrared emitting units are disposed around the lenses, achieving omnidirectional supplemental lighting and avoiding blind spots at the edges of the image due to insufficient light.
[0052] It should be noted that the above embodiments are examples for illustrative purposes only, and the scope of the rights claimed in this disclosure should be determined by the claims, and not limited to the above embodiments.
