Description

Tracking safety lighting device TECHNICAL FIELD

[0001] The present application relates to a tracking safety lighting device, in particular, a tracking safety lighting device that senses and actively tracks lighting by optical image. BACKGROUND

[0002] In the prior art, the sensing means of a conventional safety lighting device usually selects a pyro-electric infrared detector (PIR sensor) that monitors infrared rays emitted by a moving object (e.g., a person or an animal) as the main sensing implementation means.

[0003] At the same time, a single or limited number of PIR sensors are further used in combination with at least one of a fixed lighting lamp, a warning flash light (e.g., a blue / red / white flash light), and / or an alarm, or a combination thereof, to passively generate light and / or sound deterrent means such as light and / or sound when the PIR sensor senses that a person or an animal enters the monitoring range, thereby achieving the purpose of security monitoring to deter potential intruders or intruding animals.

[0004] The prior art safety lighting device that simply uses a PIR sensor as the main sensing means cannot specifically identify the specific image situation in the monitoring range (e.g., it may not accurately distinguish between a person or an animal, and it cannot know the specific position / area of the monitored moving object in real time), and therefore another common prior art is subsequently proposed, which is mainly based on the use of a PIR sensor in combination with at least one camera component to provide image information within the monitoring range, so that the user can simultaneously implement human eye video monitoring and human eye recognition of the type of intruding object; wherein the safety lighting device with at least one camera component only provides a simple image recording function, and the camera or video recording can only be further activated based on the sensing results of the PIR sensor, and does not involve any active image recognition function.

[0005] However, whether it is the aforementioned safety lighting device with only a PIR sensor or the safety lighting device with a PIR sensor combined with at least one camera component, the prior art method cannot identify and sense any other moving objects other than a person or an animal in the first place, and therefore, the prior art method has a significant risk of failing to successfully activate the sensing lighting to implement security monitoring.

[0006] Furthermore, the deterrent means used when a person or an animal is sensed to enter the monitoring range in the above-mentioned prior art method still belongs to the nature of a more standard and passive reaction, lacking the powerful deterrent function of active tracking monitoring.

[0007] Therefore, how to further propose a security lighting device that can more accurately identify monitoring and has stronger intimidation and active tracking function on the basis of the prior art is the purpose of the present application. TECHNICAL PROBLEM

[0008] One of the purposes of the present application is to provide a tracking type security lighting device that senses and tracks lighting based on the optical image of various moving objects including human shapes. Another purpose of the present application is to provide a tracking type security lighting device that actively tracks and monitors lighting in synchronization with the movement of various moving objects including human shapes when sensing the optical image of various moving objects. TECHNICAL SOLUTION

[0009] The present application provides a tracking type security lighting device, comprising: a camera having a camera lens, the camera being used to capture an optical image of a moving object; a control and analysis unit electrically connected to the camera, used to input the optical image, and through an optical image analysis program, to obtain an image analysis information, and generate a light source tracking control signal; wherein the image analysis information at least includes a visible range of the camera, and a specific spatial position of the moving object within the visible range; and a LED tracking lighting source electrically connected to the control and analysis unit, the LED tracking lighting source generates a tracking lighting light according to the light source tracking control signal, and is used to actively and continuously track and irradiate the moving object, so that the moving object remains in an illumination area.

[0010] In an embodiment of the present application, the camera lens can be adjusted by manual or software setting automatic rotation to fine-tune the initial setting procedure of the camera lens.

[0015] In one embodiment of the present application, the LED tracking illumination source has a focusing LED lens to provide the LED tracking illumination source to irradiate the moving object in a focused light emitting mode.

[0017] In one embodiment of the present application, the control and analysis unit can drive the horizontal rotation motor and the vertical rotation motor to perform the left-right rotation in the horizontal direction and the up-down rotation in the vertical direction, respectively, so that the LED tracking illumination source can actively track the moving object with a rotation angle of nearly 360 degrees.

[0018] In one embodiment of the present application, when a plurality of moving objects appear successively at different times, the control and analysis unit takes the one that is closer to the previously detected moving object as the single target for tracking and monitoring.

[0019] In one embodiment of the present application, when there are a plurality of LED tracking illumination sources, the control and analysis unit can simultaneously control the LED tracking illumination sources to independently track different moving objects, respectively.

[0020] In one embodiment of the present application, the camera lens does not rotate with the movement of the moving object, while the LED tracking illumination source can rotate with the movement of the moving object.

[0021] In one embodiment of the present application, the camera lens and the LED tracking illumination source can both rotate together with the movement of the moving object.

[0022] In one embodiment of the present application, when the moving object appears on a side close to the center of the visual range, the control and analysis unit controls the LED tracking illumination source to rotate towards the side so that the moving object remains in the illumination area, and the camera lens will also rotate towards the side synchronously until the moving object appears near the middle position of the visual range.

[0026] In one embodiment of the present application, the focused lighting LED lamp set includes at least two focused lighting units with different vertical focal lengths for providing focused lighting in different vertical ranges by the at least two focused lighting units in turn.

[0027] In one embodiment of the present application, the tracking lighting source of LED with the at least two focused lighting units with different focal lengths is only rotated in left and right directions by the movement of the mobile object in horizontal directions, and is not rotated in up and down directions by the movement of the mobile object in vertical directions.

For the sake of brevity, the disclosures of publications, including patents, contained in this specification are hereby incorporated by reference.

[0053] The following embodiments of the present application are non-limiting and represent only various specific embodiments and features of the present application. Any person skilled in the art, upon knowing and understanding the spirit of the present application, can make any equivalent changes or designs, and the specific implementation concept of the present application is not limited to the various embodiments listed below.

[0054] Please refer to Figures 1A to 2B; Figure 1A is a perspective structural schematic diagram of a first preferred embodiment of the present application, Figure 1B is an operational concept schematic diagram of the first preferred embodiment of the present application, and Figures 2A and 2B are partial front view and partial side view structural schematic diagrams of the first preferred embodiment of the present application, respectively.

[0055] In Figure 1A, the tracking safety lighting device 1 of the first preferred embodiment of the present application is provided with a camera lens 11 (and the number is not limited) at the (near) middle of the structural body, which is used to shoot optical images of various moving objects including human forms, and further execute an optical image analysis program by a built-in controller (not shown in the figure) or an image analysis software connected to a cloud server, so as to accurately identify and generate various dynamic image analysis information of the types, object shapes, volume sizes, positions, moving trajectories, and distances between various moving objects and the tracking safety lighting device 1, etc.

[0056] Preferably, the camera lens 11 can be adjusted by a manual or automatic rotation R1 set by software, according to the actual application, to further fine-tune the shooting angle or focusing distance, aperture size, and other initial settings required by the camera lens 11 before shooting.

[0057] Preferably, the camera lens 11 can not only be used for shooting in daylight or in an environment with ambient lighting, but also can be modified to have the function of shooting in a night or low ambient lighting environment.

[0058] Preferably, the camera lens 11 can also be a camera lens that can automatically detect ambient light to actively and at any time adjust or switch various shooting modes.

[0059] Preferably, the camera lens 11 can also be a camera lens that can measure the Z-axis distance between each image point and the camera to form three-dimensional spatial information.

[0060] Preferably, the camera lens 11 can also use a wide-angle lens, and the number is not limited to one, but can also be two or more. In addition, in FIGS. 1A and 1B, the tracking safety lighting device 1 of the first preferred embodiment of the present application is provided below the structure (for example, below the camera lens 11) with a LED tracking lighting source 12 with a focusing LED lens (LED-LENS), which serves as a lighting source that can automatically track the movement of a moving object.

[0061] In other words, please refer to FIGS. 1A to 2B, the space corresponding and setting relationship between a horizontal rotation motor 13, a vertical rotation motor 14 and the LED tracking lighting source 12 with a focusing LED lens (LED-LENS) inside the tracking safety lighting device 1 of the first preferred embodiment of the present application; in addition, the specific method of the LED chip 121 in the LED tracking lighting source 12 can be implemented by using the direct packaging of LED chip (COB-LED), but the present application is not limited thereto.

[0062] In which, according to the image analysis information obtained by the cooperation of the camera lens 11 and the image analysis software, the microcontroller (MCU) (not shown in the figure) provided inside the tracking safety lighting device 1 can drive the horizontal rotation motor 13 and the vertical rotation motor 14 to perform a left-right rotation R2 in the horizontal direction and an up-down rotation R3 in the vertical direction, respectively, so that the LED tracking lighting source 12 with a focusing LED lens can actively track the movement of a moving object (for example, a person or an animal) with a rotation angle of nearly 360 degrees.

[0063] For the convenience of discussion, the following mobile object will be exemplified as a "human form" for the purpose of illustration, but the present case is not limited thereto.

[0064] Of course, the control means for driving the aforementioned horizontal rotation motor 13 and / or the vertical rotation motor 14 to rotate is not limited to the microcontroller (MCU) provided inside the tracking safety lighting device 1, but can also be a system on a chip (SoC) from an image control circuit board (not shown) inside a camera (not shown) installed with the camera lens 11, and the present case is not limited thereto. Accordingly, when the mobile object (human form) enters the sensing monitoring area, no matter where the mobile object (human form) appears, there is a tracking illumination light that actively and closely tracks and illuminates at any time, thereby forming a strong deterrent force against potential intruders.

[0065] Among them, the specific implementation of the optical image analysis program executed by the image analysis software to analyze and judge the moving direction and distance of the mobile object (human form), the preferred embodiment adopted by the present case is mainly to analyze and calculate the specific spatial position of the mobile object (human form) in the two-dimensional (or three-dimensional) field of view (FOV) of the camera lens 11, so that the LED tracking illumination source 12 rotates to the required tracking angle, but the present case is not limited thereto.

[0066] In addition, when the optical image of various mobile objects including human forms captured by the camera lens 11 appears multiple mobile objects (human forms) successively at different times, the preferred method of the present case is to take the one with a closer distance to the specific spatial position of the mobile object (human form) originally detected (i.e., the position information of the mobile object (human form) detected last time) as the only target for continuous tracking monitoring, and as the main basis for calculating the next turning angle of the LED tracking illumination source 12, and ignoring other newly appearing mobile objects (human forms).

[0067] But the present case is not limited thereto, and there can be other different implementations, for example, multiple mobile objects can also be monitored simultaneously, and different angle tracking illumination monitoring can be performed by controlling multiple LED tracking illumination sources (not shown) respectively.

[0068] In addition, the aforementioned optical image analysis program executed by the image analysis software can be implemented by an AI algorithm or a deep learning algorithm as the operation core to obtain more accurate image recognition information.

[0069] The AI algorithm or the deep learning algorithm can at least include a convolutional neural network (CNN) and / or at least include a recurrent neural network (RNN), and the present application is not limited thereto.

[0070] In addition, the relationship between the camera lens 11 and the LED tracking illumination source 12 can also have at least the following two preferred operation modes, and the present application is not limited thereto:

[0071] 1. The camera lens 11 is fixed and does not rotate, but the LED tracking illumination source 12 can be automatically tracked and rotated to a certain fixed angle according to the moving position of the moving object (human form) to perform tracking illumination (as shown in Figures 1A to 2B);

[0072] 2. The camera lens 11 and the LED tracking illumination source 12 rotate together (not shown); wherein in this mode, the moving object (human form) is placed in the middle of the visual range (FOV) as the reference, for example, when the moving object (human form) appears on the left side near the center of the visual range (FOV), the LED tracking illumination source 12 rotates to the left to perform tracking illumination on the moving object (human form), and at the same time, the camera lens 11 will also rotate to the left side synchronously until the moving object (human form) appears in the middle position near the visual range (FOV). Please refer to Figures 1A and 1B, above the structure of the first preferred embodiment of the tracking safety lighting device 1 of the present application, an LED fixed illumination source 15 can be added, which is used to provide an illumination deterrent means when a moving object (human form) is found in the sensing and monitoring area, and also serves as an environmental lighting light to enhance the image quality of the optical image of various moving objects including human form photographed by the camera lens 11, thereby improving the accuracy of subsequent optical image analysis procedures.

[0073] Preferably, the LED fixed illumination source 15 can be adjusted according to the actual application situation by manual or software setting automatic left-right rotation R4, and the present application is not limited thereto.

[0074] In addition, the structure of the tracking security lighting device of the first preferred embodiment shown in FIG. 1A and FIG. IB can have various transformation modes. For example, as shown in FIG. 1A and FIG. IB, the three components of the LED fixed lighting source 15, the camera lens 11 and the LED tracking lighting source 12 are vertically arranged. Alternatively, the tracking security lighting device 1 can be designed to rotate clockwise or counterclockwise by at least 90 degrees around the camera lens 11, so that the three components of the LED fixed lighting source 15, the camera lens 11 and the LED tracking lighting source 12 are horizontally arranged. For example, after rotating 90 degrees clockwise around the camera lens 11, the LED fixed lighting source 15 is located on the right side of the camera lens 11, and the LED tracking lighting source 12 is located on the left side of the camera lens 11.

[0075] Referring to FIG. 3, a top view of the tracking lighting monitoring concept of the first preferred embodiment is shown, in which the camera lens 11 of the tracking security lighting device 1 has a maximum monitoring distance of 9 meters, and can monitor an angle of about 180 degrees (preferably within 160 degrees). The tracking security lighting device 1 is used to monitor a moving object O (a human) in a spot light mode.

[0076] Referring to FIG. 4, a side view of the tracking lighting monitoring concept of the first preferred embodiment is shown. When the tracking security lighting device 1 is installed at a height of 2.5 meters, and the angle of the field of view (FOV) of the lens is about 50 degrees, for a moving object O (a human) with a height of 1.65 meters, only about half of the height of the human can enter the field of view (FOV) of the lens at a distance of 1 meter. The whole body of the human O can enter the field of view (FOV) of the lens only at a distance of 2 meters. If the height of the human O is greater than 1.65 meters, a higher proportion of the human can enter the field of view (FOV) of the lens at a distance of 1 meter. Referring to FIG. 5A Fig. 5C is a perspective view of the tracking safety lighting device of a second preferred embodiment of the present application, showing the structure of the tracking safety lighting device of the second preferred embodiment of the present application in three different directions, respectively; wherein the structure of the tracking safety lighting device of the second preferred embodiment of the present application is obviously different from the structure of the tracking safety lighting device of the first preferred embodiment of the present application shown in Figs. 1A and 1B; wherein one of the main differences between the two is that the structure of the tracking safety lighting device of the second preferred embodiment of the present application eliminates the LED fixed lighting source 15 of the tracking safety lighting device of the first preferred embodiment of the present application.

[0077] Preferably, the LED tracking lighting source 22 (with a lampshade 220) of the tracking safety lighting device of the second preferred embodiment of the present application can moderately increase the number of LED dies due to its larger installation space, thereby greatly improving the lighting brightness to compensate for the lack of the LED fixed lighting source.

[0078] Another difference between the structures of the tracking safety lighting devices of the first and second preferred embodiments of the present application is that Fig. 5A The lamp head (i.e., the LED tracking lighting source) of the second preferred embodiment of the present application shown in Fig. 5C is implemented in a different manner (please refer to Figs. 6A to 6C), for example, the LED tracking lighting source 22 is arranged above the camera lens 21, without being limited thereto.

[0079] In addition, the horizontal rotation motor (not shown in the figure) and the vertical rotation motor (not shown in the figure) used by the tracking safety lighting device of the second preferred embodiment of the present application can be respectively arranged in the internal space of the horizontal rotation shaft P1 and the vertical rotation shaft P2 shown in Fig. 5C, without being limited thereto.

[0080] Furthermore, the LED tracking lighting source 22 used by the tracking safety lighting device of the second preferred embodiment of the present application can be further implemented in different manners, please refer to Figs. 6A to 6C; wherein Fig. 6A is a structural concept diagram of the LED tracking lighting source 22 of the second preferred embodiment of the present application implemented in a first scheme with a diffused light emitting LED lamp group 221, Fig. 6B is a structural concept diagram of the LED tracking lighting source implemented in a second scheme with a focused light emitting LED lamp group 222, and Fig. 6C is a structural concept diagram of the LED tracking lighting source 22 of the second preferred embodiment of the present application implemented in a third scheme combining the diffused light emitting LED lamp group 221 and the focused light emitting LED lamp group 222.

[0081] Of course, for further illustrating the preferred implementation of the diffused light emitting LED lamp set 221 and / or the focused light emitting LED lamp set 222 adopted in the present case, the LED tracking illumination light source 22 shown in Figs. 6A to 6C all cancel the lamp shade 220 in Figs. 5A and 5B, so as to facilitate presenting the diffused light emitting LED lamp set 221 and / or the focused light emitting LED lamp set 222.

[0082] In detail, the LED tracking illumination light source 22 of the second preferred embodiment of the present case in Fig. 6A adopts the diffused light emitting LED lamp set 221 belonging to the first scheme, that is, adopts the diffused light emitting LED lamp set with general specifications (i.e., without focusing characteristics), so that the tracking illumination light rays thereof, when projected, will not form different focused illumination projections according to the different distances of the illumination, but will directly form an illumination mode of a diffused illumination area (FLA) in all directions.

[0083] Please also refer to Fig. 7A Fig. 7B is a top view and a side view conceptual schematic diagram of the mechanism operation of the LED tracking illumination light source 22 of the second preferred embodiment of the present case, which adopts the diffused light emitting LED lamp set 221 belonging to the first scheme, for performing tracking illumination monitoring, wherein the second preferred embodiment of the present case utilizes the arrangement of the horizontal rotation shaft P1 and the vertical rotation shaft P2 shown in Fig. 5C, so as to control the LED tracking illumination light source 22 to perform horizontal left-right rotation R5 (as shown in Fig. 7A) following the movement of the moving object (human figure), and to control the LED tracking illumination light source 22 to perform vertical up-down rotation R6 (as shown in Fig. 7B), or alternatively, to control the LED tracking illumination light source 22 to perform only one of the left-right rotation R5 and the up-down rotation R6.

[0084] For example, for the second preferred embodiment of the present case, which adopts the diffused light emitting LED lamp set 221 belonging to the first scheme, the LED tracking illumination light source 22 can be controlled to perform only horizontal rotation following the left-right movement of the moving object (human figure), but the LED tracking illumination light source 22 always forms a tracking illumination mode of a diffused illumination area FLA in a fixed downward camera illumination angle (e.g., 160 degrees) in the vertical direction.

[0085] In the second preferred embodiment of the present application, the LED tracking illumination light source 22 adopts the first scheme of the diffused light emitting LED lamp group 221 to form the diffused illumination area FLA. For a better understanding, please refer to FIG. 8A, which is a top view of the implementation concept of the LED tracking illumination light source 22 adopting the first scheme of the diffused light emitting LED lamp group 221 to form the diffused illumination area FLA, and taking the optical image of a human figure O as an example to illustrate the top view of the implementation concept of the tracking illumination monitoring. Also, please refer to FIG. 8B, which is a combined illustration of the top view and side view of the implementation concept of the LED tracking illumination light source 22 adopting the first scheme of the diffused light emitting LED lamp group 221 to form the diffused illumination area FLA, and taking the optical image of a human figure O as an example to illustrate the combined illustration of the top view and side view of the implementation concept of the tracking illumination monitoring.

[0086] On the other hand, in the second preferred embodiment of the present application, the LED tracking illumination light source 22 in FIG. 6B adopts the second scheme of the focused light emitting LED lamp group 222. Please also refer to FIG. 9A FIG. 9B is a front view and a top view of the implementation concept of the mechanism operation of the tracking illumination monitoring in the second preferred embodiment of the present application, in which the LED tracking illumination light source 22 adopts the second scheme of the focused light emitting LED lamp group 222.

[0092] In addition, in FIG. 10A, the farthest monitoring distance is changed to 9M (meters), so the focused light-emitting LED unit group 222 in the LED tracking illumination light source 22 can be divided into the focused light-emitting unit A responsible for the focused illumination of the distance of 9-6M (meters), the focused light-emitting unit B responsible for the focused illumination of the distance of 6-3M (meters), and the focused light-emitting unit C responsible for the focused illumination of the distance of 3-1M (meters).

[0093] In addition, referring to FIG. 11, which is a schematic diagram of the actual tracking image when performing tracking illumination monitoring, and taking the optical image of a human figure O as an example, it is illustrated how to use the focusing light-emitting units A responsible for different projection focal lengths to form the focusing illumination area SLA C, a schematic diagram of the actual tracking image when performing tracking illumination monitoring, so that the illumination mode of the focusing illumination area SLA formed by the focusing light-emitting LED lamp group 22 belonging to the second scheme in the second preferred embodiment of the present application can be further understood.

[0095] As can be clearly seen in FIG. 6C, the LED tracking illumination light source 22 has both the diffusing light-emitting LED lamp group 221 and the focusing light-emitting LED lamp group 222; wherein the diffusing light-emitting LED lamp group 221 can be used as basic monitoring illumination, and the focusing light-emitting LED lamp group 222 can be used for more intensive monitoring illumination in different projection focal length illumination areas.

[0096] Of course, another preferred method can also automatically select either the diffusing light-emitting LED lamp group 221 or the focusing light-emitting LED lamp group 222 for driving use according to the actual application field.
