The processing module 10 controls the illumination module 12 to initiate illumination, and controls the direction of the second camera module 18 toward the surrounding environment through the movable module 14, so that the second camera module 18 faces the direction to obtain the surrounding environment. image.

For convenience of description, the first camera module 16 of the present embodiment is described by, for example, a fisheye lens that acquires a panoramic image, and the second camera module 18 is, for example, a lens that zooms and acquires a partial image. Therefore, the monitoring device 1 passes through the first camera module 16 to obtain a panoramic image of a monitoring space, and passes through the second camera module 18 to obtain a partial image of a monitoring space. This embodiment does not limit the aspect of the monitoring device 1. In detail, the processing module 10 is, for example, a central processing unit, a microprocessor, a controller, or a decision logic. In practice, the processing module 10 is used to calculate or process the signals generated by the modules or the signals transmitted between the modules. This embodiment does not limit the aspect of the processing module 10.

The processing module 10 controls the movable module 14 to move or rotate according to the fixed-point patrol mode, the patrol mode or the non-tourning mode, so that the second photographic module 18 faces the surrounding environment.

Further, the cruise mode is, for example, the movable module 14 at a fast, medium speed, and slow speed. Speed or other speed cruises. Therefore, the second photographic module 18 will be in a photographic state of dynamic patrol. The fixed-point patrol mode is, for example, that the movable module 14 performs a patrol on a plurality of fixed positions, or the movable module 14 performs a patrol on a specific fixed position. In addition, the non-tracking mode is, for example, a general mode or other modes, for example, the movable module 14 is in a standby, dormant, or stationary state. This embodiment is not limited to the aspects of the point cruise mode, the cruise mode, and the non-tour mode.

For convenience of description, the light-emitting module 12 of the present embodiment is described by an infrared light emitter. In other embodiments, the light module 12 is, for example, a white light emitter, a yellow light emitter, a blue light emitter, or a green light emitter. This embodiment does not limit the aspect of the light emitting module 12. Further, the light-emitting module 12 is coupled to the processing module 10 for illuminating a surrounding environment. The light-emitting module 12 emits a light wave to the surrounding environment, and reflects the light wave through the surrounding environment, and receives the reflected light wave in the first camera module 16 , and the first camera module 16 generates a first image signal to the processing module 10 .

That is to say, the light-emitting module 12 and the first camera module 16 can be regarded as an active infrared sensor, wherein the infrared light emitter continuously emits infrared light waves to the surrounding environment, and when the first camera module 16 receives the reflected infrared rays, In the case of light waves, the first camera module 16 acquires the first image signal of the surrounding environment or object. Similarly, when the second camera module 18 receives the reflected infrared light, the second camera module 18 acquires the second image signal of the surrounding environment or object. Therefore, the first and second camera modules 16, 18 can obtain images of the surrounding environment or images of objects.

The movable module 14 is coupled to the processing module 10. In practice, the movable module 14 includes a first rotating unit and a second rotating unit. The first rotating unit rotates the axis as a rotating axis, and the first rotating unit rotates in a clockwise direction or a counterclockwise direction, so that the second photographic module 18 moves or rotates around the extending cylinder, and the second rotation The unit moves or rotates in a top view direction or a bottom view direction, causing the second photographic module 18 to perform a pitch rotation.

In other words, the movable module 14 can perform omnidirectional movement of the three-dimensional space. The movable module 14 is realized by, for example, a PTZ (Pan/Tilt) omnidirectional moving pan/tilt. That is It is said that the movable module 14 passes through the first rotating unit to perform the left/right turn movement. The movable module 14 passes through the second rotating unit to perform the up/down movement. This embodiment does not limit the aspect of the movable module 14.

The first and second camera modules 16 and 18 are coupled to the processing module 10. In practice, the first camera module 16 is used to obtain a panoramic image of the surrounding environment. The second photographic module 18 is configured to zoom and obtain a partial image of the surrounding environment, and the first photographic module 16 has a first photographic angle. The second photographic module 18 has a second photographic angle, and the first photographic angle is greater than the second photographic angle. The first camera module 16 is in a fixed position to obtain a panoramic image. The second camera module 18 is in a dynamic position, lens zoom or zoom control to obtain a partial image.

It is worth mentioning that the second camera module 18 is disposed on the movable module 14 . The second photography module 18 has functions such as lens zoom and zoom control. That is to say, the second camera module 18 transmits the lens zoom and zoom control to zoom in or out of the scene, thereby amplifying the partial image of the panoramic image. In addition, the processing module 10 controls the movable module 14 and the second camera module 18 to operate according to a specified target, thereby tracking the specified target and acquiring the image of the specified target. For example, the designated target is a basketball, and the processing module 10 controls the movable module 14 and the second photography module 18 according to the moving position of the basketball, thereby achieving the effect of tracking the basketball and obtaining images of the basketball and its surrounding environment.

The positioning module 20 is coupled to the processing module 10. In practice, the positioning module 20 has a reference origin. The movable module 14 is realized by, for example, a stepping motor, and the positioning module 20 is realized, for example, by a positioning soft body or a positioning firmware for controlling the stepping motor. Therefore, the processing module 10 controls the operation of the movable module 14 according to the reference origin and the coordinates of the stepping motor.

In other embodiments, the positioning module 20 can also be implemented by a gyroscope. The gyroscope is disposed in the second photography module 18 . Therefore, the positioning module 20 outputs a positioning signal to the processing module 10 according to the position of the second camera module 18, so that the processing module 10 obtains the position of the second camera module 18. This embodiment does not limit the aspect of the positioning module 20.

It should be noted that in other embodiments, the monitoring device 1 can also include a sensing module (not shown). The sensing module is implemented, for example, by an infrared sensor, a microwave sensor or a laser sensor. The sensing module is used to sense or detect an object. When the object is detected, the sensing module outputs a sensing signal to the processing module 10, thereby triggering the lighting module 12 to emit light or operate. Those skilled in the art will be aware of infrared light sensors, microwave sensors or laser sensors. This embodiment does not limit the aspect of the sensing module.

From this, it can be seen that when the night or the amount of light is insufficient, the general monitoring device cannot obtain images of the surrounding environment or objects. Therefore, when the processing module 10 determines that the amount of light received by the first camera module 16 is lower than a preset value, the processing module 10 activates the light-emitting module 12, and controls the movable module 14 to move in the processing module 10. Or rotating, causing the second photographic module 18 to face the surrounding environment, the processing module 10 controls the illuminating module 12 to illuminate the surrounding environment corresponding to the second photographic module, and the second photographic module 18 zooms and obtains the periphery. An image of the environment.

Further, the preset value is, for example, a light amount value that separates the amount of light during the day or night. Those skilled in the art are free to design preset values. That is to say, when the amount of light is greater than or equal to a preset value, the light-emitting module 12 is in a non-lighting state. On the other hand, when the amount of light is less than the preset value, the light-emitting module 12 is in a light-emitting state. In this embodiment, the first and second camera modules 16 and 18 can be obtained at night or the amount of light to obtain the panoramic image and the partial image. This embodiment does not limit the operational aspect of the monitoring device 1.

Next, the detailed configuration of the monitoring device 1 and its operation mode will be further explained.

2 is a perspective view of a monitoring device according to another embodiment of the present invention. Please refer to Figure 2. A monitoring device 1 further includes a base B1, an extended cylinder C1 and a cover S1. The processing module 10 and the partial movable module 14 in FIG. 1 are disposed in the accommodating portion BS of the susceptor B1.

In detail, the base B1 is, for example, the body of the monitoring device 1. The base B1 has a fixed structure (not shown) for fixed connection to a wall, ceiling or designated location. its The pedestal B1 is realized, for example, by plastic, metal, wood, and/or other materials. In practice, the outer side of the base B1 is provided with a light-emitting module 12. In other words, the light emitting module 12 is surrounded and disposed on the outer side of the base B1. This embodiment does not limit the aspect of the susceptor B1.

For convenience of explanation, the extension cylinder C1 of the present embodiment is disposed at the center of the base B1. The extension cylinder C1 is connected to the base B1. In practice, the extension cylinder C1 is, for example, a hollow cylinder. The bottom of the extension cylinder C1 is connected to the base B1, and the first photography module 16 is disposed on the top of the extension cylinder C1. That is to say, the first photography module 16 is a photographic lens fixedly disposed at the top position of the extension cylinder C1.

Next, the cover S1 is connected to the base B1, and the cover S1 has an accommodating space for accommodating the first photographic module 16, the second photographic module 18, and the movable module 14. In practice, the cover S1 is realized, for example, by plastic, glass or sapphire, wherein the cover S1 is, for example, a light-transmissive or transparent material. Therefore, the first and second camera modules 16, 18 can respectively obtain a panoramic image and a partial image of the surrounding environment. This embodiment does not limit the aspect of the cover S1.

Further, the first rotating unit 141 is realized by, for example, a turntable and a rotating mechanism thereof. Thereby, the second photographic module 18 can be rotated left and right with the turntable and its rotating mechanism. The second rotation unit 142 is realized, for example, by a support arm, a rotating shaft, and a rotating gear thereof. The support arm is connected to the turntable. Thereby, the second photographic module 18 can be pitched and rotated with the rotating shaft and its rotating gear. This embodiment does not limit the aspects of the first and second rotating units 141, 142.

For example, the processing module 10 activates the light-emitting module 12 when the processing module 10 determines that the amount of light received by the first camera module 16 is lower than a predetermined value at night or when the amount of light is insufficient. When the processing module 10 controls the movable module 14 to move or rotate, so that the second photographic module 18 faces the surrounding environment, the embodiment continuously emits infrared light waves to illuminate the surrounding environment through the illuminating module 12, and the second photographic mode Group 18 zooms and captures images of the surrounding environment.

It should be noted that the light-emitting module 12 has a plurality of hairs such as infrared emitters. In the light unit 120, these light emitting units 120 are disposed on the outer side of the susceptor B1. The processing module 10 controls, according to the position of the second camera module 18, some of the light-emitting units 120 corresponding to the position of the second camera module 18 to emit light.

For example, a 360-degree circular base B1 is provided, and an illumination unit 120 such as an infrared emitter is disposed at an outer portion of the base B1 every 30 degrees, whereby the outer portion of the base B1 is provided with 12 light emitting units 120. The processing module 10 controls the movable module 14 to move or rotate, so that the second camera module 18 performs a patrol or non-tour operation. Wherein, the second photographic module 18 is moved to a position of 270 degrees, for example, the processing module 10 can control the illuminating unit 120 at a position of 270 degrees to emit infrared light waves, or the processing module 10 can control the position of 270 degrees at plus or minus 30 degrees. The light emitting unit 120 emits infrared light waves.

That is to say, the second camera module 18 is moved or rotated to any designated position through the movable module 14 , and the light-emitting module 12 corresponding to the designated position transmits the light wave to the surrounding environment. Therefore, the second camera module 18 can zoom or zoom the lens to obtain an image of the surrounding environment. In other embodiments, the light-emitting module 12 is, for example, an "illuminator that can be moved or rotated on the outer side of the base B1" and corresponds to a designated position to emit light waves to the surrounding environment.

It is worth mentioning that in other embodiments, the light-emitting module 12 is disposed, for example, on an outer portion of the base B1, and each of the light-emitting units 120 has, for example, a plurality of light-emitting elements, such as an infrared light bulb, a yellow light bulb, and a blue light. The light emitting unit 120 is composed of a light emitting element such as a light bulb, whereby the processing module 10 controls the light emitting module 12 to emit a light beam and irradiate the light beam on the object. Therefore, the first and second camera modules 16, 18 can also acquire images of the surrounding environment or objects.

3A is a schematic perspective cross-sectional view of a monitoring device according to another embodiment of the present invention. FIG. 3B is a perspective view of the first photographic module according to another embodiment of the creation of FIG. 3A. Please refer to FIG. 3A and FIG. 3B. A first camera module 16 is illustrated in FIG. 3B.

In practice, the first camera module 16 has a fisheye unit 160 and a filter switching unit 162. The fisheye unit 160 is connected to the filter switching unit 162, and the amount of light is greater than or After the light equal to the preset value enters the fisheye unit 160, the processing module 10 controls the filter switching unit 162 to block the infrared light from entering. After the light having the light amount less than the preset value enters the fisheye unit 160, the processing module 10 controls the filtering. The light switching unit 162 allows infrared light to enter. That is to say, after the daytime light enters the fisheye unit 160, the processing module 10 controls the filter switching unit 162 to block the infrared light from entering, and after the night light enters the fisheye unit 160, the processing module 10 controls the filter switching. Unit 162 is for infrared light to enter.

Further, the filter switching unit 162 is implemented, for example, by an IR-CUT dual filter switch. The function of the filter switching unit 162 for the first camera module 16 corrects the daytime color cast problem and enhances the night brightness. Among them, the IR-CUT dual filter switch includes a filter and a power component. The filter is realized, for example, by a piece of infrared cut-off or absorption filter and a piece of fully transparent spectral filter. The power components are realized, for example, by electromagnetic, electric or other power sources. This embodiment does not limit the aspect of the filter switching unit 162.

For example, the IR-CUT dual filter switcher works when the daylight is full, the IR cut filter works, and the CCD restores true color. When the night or the amount of light is insufficient, the infrared cut-off/absorption filter is automatically removed, and the full-transmission spectral filter starts to work, so that the CCD makes full use of all the light, thereby improving the low-light performance. In addition, it can be seen that the second photographic module 18 also has a filter switching unit. In this embodiment, the first photographic module 16 determines whether the amount of light is less than a preset value.

Next, the detailed operation of the monitoring device 1 and its application will be further explained.

The processing module is, for example, in a fixed-point cruise mode, in which the fixed-point cruise mode tracks each of the children O1 ^~ O5 in turn. Of course, the five children O1 ^~ O5 can move freely in the classroom to change their position.

That is to say, each of the children O1 ^~ O5 will have a time of, for example, 5 seconds being tracked by the second photography module 18 and taking a magnified image picture. In addition, fixed-point cruise mode operation in accordance with the cruise lines were designated I, II, III, IV and V children of tracking mode O1 ^~ O5. In short, after the second photography module 18 tracks the No. 1 child O1, it will switch to track the No. 2 child O2. Similarly, after the second photography module 18 tracks the third child O3, it will switch to track the fourth child O4. After the second photography module 18 tracks the fifth child O5, it will switch to track the No. 1 child O1. This embodiment is not limited to the tracking mode and aspect of the point cruise mode.

For example, the first photography module 16 can obtain a panoramic image in the classroom. And the processing module can know the position of the No. 2 child O2 from the panoramic picture, whereby the processing module controls the movable module to move to the position corresponding to the position of the No. 2 child O2, and controls the second photography module 18 to zoom and obtain two. No. No. O2's picture. After 5 seconds, the processing module can obtain the position of the third child O3 through the panoramic picture in the classroom acquired by the first photography module 16, and the processing module controls the movable module to move to the position corresponding to the third child O3. Angle, and control the second camera module 18 to zoom and obtain the picture of the third child O3. Wherein, the first rotating unit of the movable module rotates in a clockwise direction to a position of about 120 degrees. The second rotating unit rotates in a plan view.

After 5 seconds, the processing module can know the position of the fourth child O4 through the panoramic picture in the classroom obtained by the first photography module 16, and the processing module controls the movable module to move to the position corresponding to the fourth child O4. Angle, and control the second camera module 18 to zoom and obtain the picture of the fourth child O4. Wherein, the first rotating unit of the movable module is rotated in a counterclockwise direction to a position of about 30 degrees. The second rotating unit is rotated in the upward viewing direction. Similarly, after 5 seconds, the processing module can know the position of the fifth child O5 through the panoramic picture in the classroom obtained by the first photography module 16, and the processing module controls the movable module to move to the corresponding fifth number. The angle of the position of the child O5, and control the second camera module 18 zoom and get the picture of the fifth child O5 surface. Wherein, the first rotating unit of the movable module rotates in a clockwise direction to a position of about 210 degrees. The second rotating unit rotates in a plan view.

In other embodiments, the monitoring device 1 can also be placed on a soccer field, a basketball court, or other location. The first camera module 16 is a panoramic image, and the second camera module 18 is used to zoom, track and obtain a partial image of the environment in which the football is located in the football field, or a part of the environment in which the basketball ball is located in the basketball court. image. Briefly, in this embodiment, the first camera module 16 is used to obtain a panoramic image, and the second camera module 18 is used to track and obtain a partial image of the environment in which the object is located. The object is for example an animal, a person, a ball or the like. In brief, when the object runs to any position in the surrounding environment, the second camera module 18 tracks the environment location of the object, and the partial image can complement the problem that the panoramic image is unclear or the picture is too small.

FIG. 5 is a schematic diagram of the operation of a monitoring system according to another embodiment of the present invention. Please refer to Figure 5. A monitoring system, comprising a host computer (not shown) and a plurality of monitoring devices SD1 ^~ SD10. In practice, the computer host is coupled to the network. The monitoring devices SD1 ^to SD10 are respectively coupled to the computer host, and the monitoring devices SD1 ^to SD10 are respectively disposed in a plurality of regions in a monitoring space. For convenience of description, the present embodiment is described by the planes of the two-story parking lot F1 and F2, wherein each parking lot F1 and F2 is arranged with five monitoring devices SD1 ^to SD10, as shown in FIG.

In detail, the computer host transmits a monitoring data to the monitoring devices SD1 ^to SD10, and when one of the monitoring devices SD1 ^to SD10 obtains an identification data of the object OC through the second imaging device, the processing module monitors according to the monitoring The data is compared with the identification data. When the processing module determines that the identification data belongs to the monitoring data, one of the monitoring devices SD1 ^to SD10 detects the object OC. When one of the monitoring devices SD1 ^to SD10 detects an object OC, the monitoring device SD1 ^~ SD10 detecting the object OC outputs a detection signal to the host computer, and the computer host controls according to the moving path of the object OC. The monitoring devices SD1 ^to SD10 respectively monitor the object OC.

For example, the monitoring data is, for example, the license plate information of the building occupants, and the identification data is, for example, a license plate image. Therefore, when the vehicle of the household is to enter the parking lot, the monitoring device SD1 can obtain the license plate image of the vehicle through the second photography module. The processing module will compare the license plate image according to the license plate data. When the processing module determines that the license plate image belongs to the license plate information of the building owner, the monitoring device SD1 outputs the detection signal to the host computer. Therefore, the host computer monitors the vehicles in turn according to the moving path of the vehicle to control the monitoring devices SD1 ^to SD5.

In addition, the host computer can know that the parking space of the vehicle is in the second floor parking lot F2 according to the detection signal. Therefore, when the monitoring device SD4 tracks the vehicle to the second floor parking lot F2, the second camera module of the monitoring device SD4 passes through the second rotating unit to photograph the vehicle into the hill. Next, the host computer will control the monitoring device SD6 of the second floor parking lot F2 to track and photograph the vehicle.

Thereafter, the second camera module of the monitoring device SD6 passes through the second rotating unit to take a bird's eye view from the hill. And the computer host controls the vehicles in turn according to the moving path of the vehicle to control the monitoring devices SD6 ^~ SD10. This embodiment does not limit the operation of the monitoring system.

In other embodiments, each of the monitoring devices SD1 ^to SD10 further includes an identification module (not shown), and the identification module is configured to wirelessly identify an identification chip (not shown) of the object OC, and the monitoring devices SD1 ^~ When one of the SD10 recognizes the identification chip of the object OC, the monitoring devices SD1 ^to SD10 that recognize the identification chip output an identification signal to the computer host, and the computer host controls the monitoring devices SD1 ^to SD10 according to the moving path of the object OC. Monitor the object OC.

For example, the identification module is implemented, for example, by RFID recognition technology, wi-fi recognition technology, Bluetooth communication recognition technology, or other wireless communication recognition technology. This embodiment does not limit the aspect of the identification module. Among them, the vehicles of the building occupants are equipped with identification chips for communication and identification with the identification module, and the identification chips can be realized through the building resident parking permit or bracelet or other objects. Therefore, when the resident's vehicle is to enter the parking lot, the monitoring device SD1 can wirelessly recognize the identification chip of the vehicle through the identification module. When the monitoring device SD1 recognizes the identification chip of the vehicle, the monitoring device SD1 outputs an identification signal to the computer host, and the computer host controls the monitoring devices SD1 ^to SD10 to monitor the vehicle in turn according to the moving path of the vehicle.

The monitoring device includes a processing module, a lighting module, a movable module, a first camera module and a second camera module, and the processing module is coupled to the light module. The movable module, the first photography module and the second photography module, and the monitoring methods include: In step S601, it is determined whether the amount of light received by the first camera module is lower than a preset value. In practice, there is ample light during the day. On the contrary, the night does not have a sufficient amount of light. In this embodiment, the preset value is used to distinguish the amount of light, for example, day or night. Therefore, in addition to acquiring images during the day, the monitoring device can also acquire images at night or in an environment with insufficient light.

If the determination result in step S601 is YES, then the process proceeds to step S603, and the processing module controls the light-emitting module to start lighting. Next, in step S605, the processing module controls the direction of the second camera module toward the surrounding environment through the movable module, so that the second camera module obtains the image of the surrounding environment in the direction. In other words, when the processing module controls the movable module to move or rotate, so that the second photographic module faces the surrounding environment, the processing module controls the illuminating module to illuminate the surrounding environment facing the second photographic module, and The second camera module zooms and captures images of the surrounding environment.

In step S607, the processing module controls, according to the position of the second photographic module, some of the illuminating units corresponding to the position of the second photographic module to emit light. In practice, the light-emitting module has a plurality of light-emitting units disposed on the outer side of the base. If all of these lighting units are illuminated, energy is wasted. Therefore, in this embodiment, "some of the light-emitting units corresponding to the position of the second camera module facing the surrounding environment are illuminated".

Next, in step S609, the light emitting module emits light waves to the surrounding environment and reflects the light waves through the surrounding environment. In step S611, the first photography module receives The reflected light wave, the first camera module generates a first image signal to the processing module. In step S613, the second camera module receives the reflected light wave, and the second camera module generates a second image signal to the processing module.

For example, in a 360 degree peripheral environment of a ring field, if the second camera module faces a surrounding environment of 120 degrees, the light emitting unit corresponding to 120 degrees will emit light to illuminate the surrounding environment of 120 degrees. Therefore, in the case of night or insufficient light, the illumination unit such as the infrared light emitter will emit infrared light waves to the surrounding environment, so that the first and second photography modules obtain a panoramic image or a partial image of the surrounding environment.

If the determination result in the step S601 is no, the process proceeds to a step S615, the processing module controls the illumination module to not start the illumination, and the processing module controls the movable module to move or rotate, so that the second imaging module faces the surrounding environment, and the The second camera module zooms and captures images of the surrounding environment. That is to say, the lighting module does not emit light to the surrounding environment. The processing module controls the direction of the second photographic module toward the surrounding environment through the movable module, so that the second photographic module obtains an image of the surrounding environment in the direction.

It should be noted that in other embodiments, the monitoring device also includes a positioning module and an identification module. The positioning module has a reference origin. The processing module controls the movable module to move and control the corresponding lighting module to emit light according to the coordinate system of the reference origin; or the positioning module outputs a positioning signal to the processing module according to the position of the second imaging module, so that the processing module The module obtains the position of the second photography module.

In addition, the identification module is configured to wirelessly identify an identification chip of the object. When one of the monitoring devices recognizes the identification chip of the object, the monitoring device that recognizes the identification chip outputs an identification signal to the computer host, and the computer host according to the object The moving path to control the monitoring devices to separately monitor the object. The determination process and steps of the positioning module and the identification module may also be added to the process of the monitoring method of FIG. 6. This embodiment does not limit the flow steps of the monitoring method.

In summary, the present invention is a monitoring device. When the amount of light received by the first camera module is less than a preset value, the processing module activates the operation of the light module. The processing module controls the positions corresponding to the second camera module according to the position of the second camera module Some of the light-emitting units emit light. The light-emitting module emits infrared light waves to the surrounding environment, whereby the first and second camera modules can obtain panoramic images and partial images in the case of night or insufficient light. In addition, the first photographic module acquires a panoramic image of the surrounding environment in a static manner, and the second photographic module dynamically acquires a partial image of the surrounding environment. The partial image enlarges the appearance of the surrounding environment or the object in the panoramic image, so that the partial image can complement the unclear or blurred position in the panoramic image. In this way, the creation can enhance the monitoring and security protection capabilities by tracking the specified targets and obtaining partial images and panoramic images of the environment in which the specified targets are located.

The above description is only an embodiment of the present invention, and is not intended to limit the scope of the patent of the present invention.
