Monitoring system and screen display method

The present invention relates to a screen display method of a monitoring system, and more particularly to a screen display method corresponding to a relative position of a monitoring device in a monitoring system.

Whether it is a crowded shopping mall, a bustling station, or a general home community, the use of surveillance systems has become an inevitable part of modern life. The monitoring system usually takes a continuous shot of the scene with several cameras, and receives the images continuously shot by each camera through the central control host and displays them on the screen. When the user is operating, the user can switch to the object or event to be observed according to the location where the camera is installed and the screen displayed on the screen.

Please refer to the first figure (a), which is a schematic plan view showing the relative positions of the monitoring systems formed by a plurality of cameras. The cameras 111, 113, 115, 117 in the figure are installed at different corners of the apartment, and the environment profile of the cameras 111, 113, 115, 117 for recording with the cameras 111, 113 can be seen by the apartment plan 100. , 115, 117 relative position when installed.

Please refer to FIG. 2(b), which is a schematic diagram of a screen display process applied to a monitoring system composed of a plurality of monitoring devices and control devices. The screen display method applied to the monitoring system of the present invention mainly comprises the following steps: firstly providing a correspondence established according to the relative positions of the monitoring devices in the monitoring system (step S201); and then providing the first display screen through the display device (Step S202); after sensing the user to generate a control command according to the instruction operation performed by the first display screen (step S203); the control device further establishes the position correspondence relationship and the conversion instruction operation according to the relative positions of the respective monitoring devices. The obtained control command corresponds to at least one monitoring device, and the second display screen generated by the corresponding monitoring devices is displayed on the display device (step S204).

In order to further explain the details in the flowchart, the following steps will be taken in conjunction with the steps in the schematic diagram of the flow chart to illustrate various changes in the actual application of the screen display method applied to the monitoring system proposed by the present invention.

Please refer to the third figure (a), which is a schematic diagram of the relative positions of the monitoring devices in the monitoring environment. According to step S201, the blocks representing the respective monitoring devices 311, 313, 315, and 317 in the third diagram (a) are established according to the relative positions of the respective monitoring devices 311, 313, 315, and 317 when actually installed, with respect to the monitoring device. The relative positions of the 311, 313, 315, and 317 and their corresponding relationships may be established according to the method shown in the first figure (a) according to the pre-provided monitoring plan; or by the plurality of monitoring devices 311, 313, The signal connection relationship established between 315 and 317 is matched with the relative position detection functions such as position and angle, and then the monitoring devices 311, 313, 315, and 317 are mutually opposed by signal communication methods such as Bluetooth or wireless network. The position sensing further establishes and completes a schematic diagram of the relative positions of the monitoring devices 311, 313, 315, and 317 as shown in the third figure (a) in a dynamic manner.

Please refer to the third figure (b), which is a schematic diagram of storing the relative positions and correspondences of the monitoring devices in a list. The control device in the monitoring system can store the corresponding positions of the monitoring devices 311, 313, 315, and 317 through different data storage formats. For example, if the monitoring devices are used to identify the monitoring devices 311, 313, The code of 315, 317 is used as the index of the index, and the first row in the table of the third figure (b) is marked with the relative position field of the monitoring devices 311, 313, 315, 317 in the table, and the monitoring positions are The other monitoring devices 311, 313, 315, 317 installed in the respective relative positions of 311, 313, 315, 317 are coded.

In this way, after the monitoring system provides the first display screen, according to step S203, once the control device senses that the user performs an instruction operation through an input device such as a mouse, a keyboard, a joystick, or a touch screen, such as a mouse When the corresponding control cursor moves to the top of the display screen or moves from the middle of the display screen to the right side of the display screen, the control command corresponding to the instruction operation can be further matched with the field record of the relative position to obtain the corresponding The monitored device code is switched, and the content of the display screen is switched to update the original first display screen to the monitoring screen provided by the corresponding monitoring device.

Taking the monitoring device 317 as an example, the fourth column data content of the third figure (b) is established according to the monitoring device correspondence relationship shown in the third figure (a). The upper, left and right sides of the monitoring device 317 can be seen. Monitoring devices 313, 311, 315 are provided respectively.

In this case, it is assumed that the first display screen in the monitoring system initially displays the monitoring screen acquired and generated by the monitoring device 317, and if the user operates the input device, the screen on the first display screen is operated to generate an upward screen. During the moving indication operation, the control device can know that the user wants to see the relative position in front of the monitoring device 317 (above the display screen) by the correspondence table built in the control device in FIG. 3(b). In the monitoring screen of the device 313, in step S203, a control command is generated corresponding to the user's direction, position, speed, or switching mode of the instruction operation, and in step S204, the original first display screen is displayed. The monitoring screen generated by the monitoring device 317 is switched to the second display screen, and the monitoring screen generated by the monitoring device 313 is provided in the second display screen. The same method can be applied to the left of the switching monitoring screen to the left of the monitoring device 317 (switching to the monitoring screen generated by the monitoring device 311) and switching the monitoring screen to the right of the monitoring device 317 (switching to the monitoring screen generated by the monitoring device 315) In the case of the case, of course, the other monitoring devices 311, 313, and 315 can also be analogized when the display screen is switched.

It should be noted that although the third figure (b) records the relative position between the monitoring devices in the form of a comparison table, in the implementation process of the application, the data structure can be adopted according to the system performance and the like. Recording, these do not affect the way the subsequent display device operates when providing the display.

The instruction operation performed by the user may be performed by the user manually, such as a mouse, a keyboard, a joystick, a touch screen, etc., or may be performed according to a preset condition set by the user, and then The control device converts into a control command representing different characteristics such as direction, position, speed, or switching mode of the pointing operation according to different types of indication operations.

For the possible ways of indicating the operation manually, please refer to the following description of the fourth figure (a) (b), and the fourth figure (c) is a display according to the user setting the preset condition. Examples of screen switching, in other words, various manual methods and preset conditions can be applied to the monitoring system depending on the user's operating habits or functional applications.

Please refer to the fourth figure (a), which is a schematic diagram of the pointing operation performed by the mouse on the first display screen. In the fourth figure (a), the first display screen displayed by the display device 41 is planned with four detection areas, and the configurations of the four detection areas are: corresponding to the first detection above the first display screen. The measurement area 421 corresponds to a second detection area 422 on the right side of the first display screen, a third detection area 423 corresponding to the lower side of the first display screen, and a fourth detection area 424 corresponding to the left side of the first display screen. Therefore, when the user moves the cursor in the first display screen to each detection area in the first display screen, the screen displayed by the display device 41 is switched from the first display screen to the corresponding The monitoring screen generated by the monitoring device of each detection area is used as the updated second display screen.

If the user selects to display the display screen combined by the monitoring screen, at least one monitoring device is corresponding according to the correspondence relationship and the control command, and the second display screen generated by the monitoring device is displayed. The steps may be further subdivided into the following steps: first obtaining the first monitoring picture generated by the first monitoring device; then obtaining the second monitoring picture generated by the second monitoring device; and the first monitoring picture and the second monitoring A second display screen formed by combining the screens through the image processing flow.

In order to further explain the manner in which the second display screen may be generated, it is assumed here that the original first display screen displays the monitoring screen generated by the monitoring device 317 located at the lower position in the third diagram (a), provided that the user will When the cursor displayed corresponding to the mouse moves to the first detection area 421 in the display screen, the display screen presented by the display device changes correspondingly to the monitoring screen generated by the monitoring device 313 in the upper part of the screen, and the same is known. Once the cursor corresponding to the mouse is moved to the fourth detection area and the second detection side area, the screen displayed by the display device will be correspondingly switched to be the monitoring device 315 on the right side of the screen and the monitoring device on the left side of the screen. The second display screen is a combination of the monitoring screens generated by 311.

Of course, the switching of the corresponding detection area and the display screen with respect to the mouse movement is only an example. In fact, the planning of each sensing area does not necessarily adopt the planning as in the fourth figure (a), and is not necessarily It needs to be planned in four directions: up, down, left and right, and can be changed through the operation interface to provide the upper right, lower right, upper left, lower left, and even irregularly shaped sensing areas (for example, according to the planning of each room in the monitoring environment, or It is based on different monitoring area plans based on the monitoring screen generated by different monitoring devices. In addition, the operation of the special button can be additionally configured. For example, when the user presses the right mouse button, the display screen can be switched to a similar position but the monitoring screen of the monitoring device installed on different floors (for example: installed on the first floor) The monitoring device of the stairwell is switched to the monitoring device of the stairwell on the second floor to provide a monitoring screen. All the changes can be made according to the operation mode and application of the whole monitoring system.

Please refer to the fourth figure (b), which is a schematic diagram of performing an indication operation on the first display screen by using a keyboard. Providing a corresponding sensing indication 43 on the display screen of the display device 41, for example, in the form of an On Screen Display (OSD), as shown in the fourth figure (b) in the display screen, providing the indication according to different orientations. The small directional icon allows the user to adjust the monitoring screen display displayed on the display screen by the relative position of the keys on the keyboard. Of course, similar concepts can be matched and implemented in the monitoring system through different types of input devices such as a joystick or a touch screen.

When the user views the first display screen presented by the display device and through manual operation (such as the above-mentioned operation through a mouse, a keyboard operation or other user interface operations), in addition to the basic direction corresponding operation, an additional Define a more advanced mode of operation, such as controlling the speed of screen transitions based on different indication operations. For example, providing a single click for a mouse is a slow transition, while a double click for a mouse represents a fast switching feature. For example, the joystick operation can determine the speed of the screen transition speed according to the strength of the rocker when the joystick is operated or the swing amplitude of the rocker, and the duration of the keyboard operation can correspond to the speed of the screen transition for other types of The same is true for the input device.

Please refer to the fourth figure (c), which is a schematic diagram of indicating the display screen by using a preset screen block. In addition to the reason that the input device is used as the display screen to trigger the associated data, the user can also provide an auxiliary function design with the application software when viewing the display screen, for example, in the first display screen, the user corresponds to the user. A screen block 44 is selected for monitoring the location of the object, and the corresponding screen feature is extracted from the screen block 44 in conjunction with the signal processing algorithm. The monitoring system can set the tracking function of the screen block 44 and according to the screen area. The movement of the block 44 corresponds to switching the screen content displayed by the display device.

It should be noted that the manner in which the preset conditions are provided may be implemented by using different implementation manners according to system characteristics or user requirements. Therefore, according to the example of the fourth figure (c), according to the first display screen It is set by selecting the selected picture block; or by setting a plurality of sensors used in combination with a plurality of monitoring devices, so that the monitored object is triggered by the sensor when the sensor passes through the sensor. The sensing signal is sent to the corresponding monitoring device, so that the display device switches the display screen between the monitoring screens generated by the plurality of monitoring devices, without departing from the scope of the preset conditions in the present invention.

In order to simplify the description, in each of the illustrations of the fifth figure, the use of the numbers represents the monitoring screen generated by the corresponding monitoring device number, and the display screen displayed by the display device may change due to the correspondence relationship with the monitoring device. Therefore, the digitally represents the monitoring screen acquired by each monitoring device during the switching of the display screen.

Please refer to FIG. 5(a), which is a schematic diagram showing the relative positions of the monitoring devices according to the first preferred embodiment of the present invention. The fifth diagram (a) represents that in the monitoring system, the first monitoring device 511, the second monitoring device 513, the third monitoring device 515, the fourth monitoring device 517, and the fifth monitoring device 519 are used in total, wherein the first monitoring device The 511 is placed at a central position relative to the other monitoring device, and the second monitoring device 513 is in front of the first monitoring device 511 (corresponding to the upper side of the drawing), and the fourth monitoring device 517 is behind the first monitoring device 511. (corresponding to the bottom view), the fifth monitoring device 519 and the third monitoring device 515 are respectively on the left and right sides of the fourth monitoring device 517.

Referring to FIG. 5(b), FIG. 5 is a schematic diagram of screen transition when the monitoring screen generated by the first monitoring device 511 is the first display screen according to the first preferred embodiment of the present invention. According to the illustration, when the monitoring screen generated by the first monitoring device 511 is used as the first first display screen, the display position corresponding to the relative position of the monitoring device and the relative position on the screen is displayed. When the monitoring screen generated by other monitoring devices is displayed, although different display screens may be generated in response to the user's instruction operation, a similar concept can still be applied.

According to the content of the fifth figure (b), it is first assumed that the display device presents the monitoring screen generated by the first monitoring device 511, and then, according to various types of operations of the user, as described above with the arrow keys of the keyboard, If the user's instruction operation representative moves to the top of the display screen, the display screen presents a combination of the monitoring screens generated by the first monitoring device 511 and the second monitoring device 513; if the user's instruction operation represents the display screen When moving downward, the display screen presents a combination of the monitoring screens generated by the first monitoring device 511 and the fourth monitoring device 517; if the user's pointing operation represents moving to the left of the display screen, the display screen is presented by the first The combination of the monitoring device 511 and the monitoring screen generated by the fifth monitoring device 519; if the user's pointing operation represents moving to the right of the display screen, the display screen is generated by the first monitoring device 511 and the third monitoring device 515. The combination of monitoring screens.

This method is simple for the calculation of the system and the condition. As long as the control device detects that the user's instruction operation is moved upward by the monitoring screen of the first monitoring device 511, the screen displayed by the display device is changed to the second monitoring device 513. The resulting monitoring screen.

Referring to FIG. 5(d), it is a schematic diagram of the monitoring screen generated by the first monitoring device in the first preferred embodiment of the present invention being switched to the monitoring screen generated by the second monitoring device in a progressive switching manner. Such a method is more fluent to the user, and when the display device switches to the monitoring screen corresponding to the second monitoring device 513 by the monitoring screen corresponding to the first monitoring device 511 according to the movement of the monitored object, Instead of adopting the method of direct screen switching, a monitoring screen generated by the second monitoring device 513 is added to the monitoring screen generated by the first monitoring device 511, and the monitored object is getting closer and closer. The change of the monitoring area of the monitoring device 513 increases the proportion of the monitoring screen generated by the second monitoring device 513, and finally switches the screen displayed by the display device to the monitoring screen corresponding to the second monitoring device 513.

That is, during the switching of the monitoring screen, the second display screen is generated by combining the first monitoring screen generated by the first monitoring device 511 and the second monitoring screen generated by the second monitoring device 513. The adjustment of the presentation ratio of the first monitoring screen and the second monitoring screen is different, so that when the user views the monitoring screen, the display device can be presented in a relatively smooth and convenient manner.

In addition to considering the burden of the system and the smoothness of the user's operation, the screen switching modes of the two different modes as shown in FIG. 5(c)(d) are provided, and the switching of the two different modes may also be based on the user operating the input device. The mode of the time is provided. For example, if the mouse click is a slow transition and the double click is defined to quickly switch the display screen, when the user clicks on the detection area, if the mouse clicks on the detection area, In the single click mode, the screen is progressively switched in the manner of the fifth diagram (d). On the other hand, if the user uses the double click method, the display screen is switched more quickly, and the fifth screen is used. The mode of direct switching shown in Figure (c).

Please refer to the sixth figure (a), which is a schematic diagram of the relative position of the monitoring device according to the second preferred embodiment of the present invention. The sixth diagram (a) represents that in the monitoring system, the first monitoring device 611, the second monitoring device 613, the third monitoring device 615, the fourth monitoring device 617, and the fifth monitoring device 619 are used in total, and the monitoring devices are mutually The relative position between the two displays a T-shape, wherein the left and right sides of the second monitoring device 613 are respectively provided with a fifth monitoring device 619 and a third monitoring device 615, and the rear of the second monitoring device 613 (corresponding to the illustration In the lower part, the first monitoring device 611 and the fourth monitoring device 617 are sequentially disposed.

Referring to FIG. 6(b), it is a schematic diagram of a screen transition when the monitoring screen generated by the first monitoring device 611 is used as the first display screen in the second preferred embodiment of the present invention. The preferred embodiment can be used to illustrate that when the user controls the motion of detecting the screen on the display screen, the direction of the movement is not limited to the four directions of up, down, left, and right, and may be established according to the relevance of the previously set camera. More directional operations are in line with humanized intuition, and the preview display screen is not limited to displaying only two channels of pictures, and can be displayed in a multi-channel picture.

As shown in the sixth diagram (b), the display device can simultaneously display the screens of two or three channels according to the direction the user needs to monitor. First, the display device is presented with the monitoring screen generated by the first monitoring device 611. Then, according to various types of operations of the user, if the user's instruction operation represents moving to the upper left of the display screen, the display screen is presented by the first monitoring. The combination of the device 611, the second monitoring device 613 and the monitoring screen generated by the fifth monitoring device 619; if the user's instruction operation represents moving to the upper right of the display screen, the display screen is presented by the first monitoring device 611, a combination of the monitoring device 613 and the monitoring screen generated by the third monitoring device 615; if the user's pointing operation represents moving to the lower side of the display screen, the display screen is presented by the first monitoring device 611 and the fourth monitoring device 617 The combination of the generated monitoring screens.

Referring to FIG. 7(a)(b)(c)(d)(e), which is a schematic diagram of display screen switching according to a third preferred embodiment of the present invention. The user can control the transition of the monitoring screen according to the positional relationship and the demand of the monitoring device. Taking the seventh picture (a) as an example, suppose that the picture one is for taking the picture of the hall containing room one and room two, and the room one and the second room have other camera shooting, then the hall can lead to the first room and the second The two entrances of the room set the trigger conditions for specific events, so when the user is monitoring the hall screen, if the mouse or keyboard moves, move the cursor to the position shown in Figure 7 (b) and click At the same time, the picture can be converted to include both the hall picture and the first room picture (as shown in the seventh picture (c)), and gradually increase the picture ratio of the first room (such as the seventh picture (d) and the seventh picture ( e)), the user preset condition is matched with the overall space configuration diagram, and the user can manipulate the display screen in a more intuitive manner.

Please refer to FIG. 8( a ), which is a schematic diagram of a moving path of a monitored object according to a fourth preferred embodiment of the present invention. In this figure, it is assumed that there are four monitoring devices in the monitoring area for monitoring, and the moving path of the monitored object (for example, a suspicious person) first moves from the monitoring range covered by the third monitoring device 811 to the second monitoring device 813. The monitoring range is then moved to the monitoring range covered by the first monitoring device 815, and finally stays within the monitoring range covered by the fourth monitoring device 817.

Please refer to the eighth figure (b) and (c), which is a schematic diagram of the divided screen of the display device. It should be noted that the number and proportion of the display device 83 in the control center and the actually installed monitoring device may be different. For example, the eighth figure (b) is a method of providing a one-to-many monitoring screen by using a single display device 83, and In the eighth diagram (c), the display screen generated by the monitoring device is correspondingly displayed by a plurality of display devices by displaying the monitoring screen one-to-one.

Incidentally, in each of the illustrations of the eighth figure, the use of the numbers represents the monitoring screen generated by the corresponding monitoring device number, and the display screen displayed by the display device may be related to the monitoring device. As a result, the digital display represents the monitoring screen acquired by each monitoring device during the switching of the display screen.

According to the conventional technique, regardless of whether the number of display devices in the control center is equal to the number of monitoring devices, the user located in the control center is often limited by the appearance of the display device when viewing the display screen presented by the display device. The content of the display screen or the monitored object cannot be observed on the coherent/moving line due to factors such as the positional correspondence.

Please refer to the eighth figure (d) (e), which is a schematic diagram of the display system switching process performed by the monitoring system of the conventional technology using the display device. Continuing the example in which the display device and the monitoring device have a one-to-many proportional relationship with a one-to-one proportional relationship, as shown in FIG. 8(d), in the former case, the user of the control center needs to observe the monitored object. When moving (indicated by an asterisk), the monitoring screen generated by the third monitoring device 815 is first seen on the display device 83, but the monitored object is out of the monitoring range of the third monitoring device 815 and cannot be obtained from the third monitoring device. After the monitoring screen generated by 815 observes the state of the monitored object, the user needs to switch the display screen on the display device 83 to a divided screen composed of all the monitoring screens, and the user knows that the screen is monitored by dividing the screen. After the object has moved to the monitoring range corresponding to the second monitoring device 813, the display screen on the display device 83 is switched to the monitoring screen generated by the second monitoring device 813, so as to repeatedly display according to the movement of the monitored object. Switching of the screen.

In other words, if the conventional device is used to display the screen generated by the monitoring device in a one-to-many manner, according to the example of the moving path of the monitored device, the corresponding monitoring is to be performed according to the moving path of the monitored object. When the device monitors the screen, the user needs to switch the screen of the display device between the individual monitor screens and the display of the entire split screen as shown in the eighth diagram (d).

Even if the number of display devices used is in a one-to-one relationship with the number of monitoring devices, the switching process of the display screen for the display screen is still limited by the manner in which the display device presents the monitoring screen, and there is a problem that the user is not intuitive when viewing the display screen. .

As shown in FIG. 8(e), in the conventional monitoring system, the first display device 831, the second display device 832, the third display device 833, and the fourth display device 834 respectively display the first monitoring device 811, The monitoring screen generated by the second monitoring device 813, the third monitoring device 815, and the fourth monitoring device 817.

What the user initially sees is the monitoring screen generated by the third monitoring device 815 displayed by the third display device 833, but when the monitored object moves to the monitoring area corresponding to the second monitoring device 813, the user must Among the other three display devices, it is found that the monitored object has moved to the display screen of the second display device 832, and moves the gaze to the upper right corner (arrow symbol 1), thus repeatedly following the movement of the monitored object, and then The gaze moves to the monitoring screen (arrow symbol 2) generated by the first monitoring device 811 displayed by the first display device 831 in the upper left corner, and the fourth monitoring device displayed by the fourth display device 834 located at the lower right corner The monitoring screen generated by the device 817 (arrow symbol 3).

It can be found from the description of (d) and (e) of FIG. 8 that, regardless of whether the number of display devices is the same as the number of monitoring devices, the manner in which the conventional technology is used allows the user to visually search for the display screen during operation. Looking for the dynamics of the monitored objects, it is quite inconvenient in the monitoring process.

Please refer to FIG. 8(f)(g), which is a schematic diagram of a display screen switching process performed by the monitoring system according to the fifth preferred embodiment of the present invention. Here, the flow of monitoring the screen presentation is performed according to the movement of the monitoring object as shown in the eighth diagram (a), and the split screen is provided using a single display device as shown in the eighth (b) and eighth (c) drawings. The manner of using the plurality of display devices corresponding to the display screen generated by the monitoring device is explained.

In the eighth diagram (f), the monitoring system uses only one display device 83 to present the screen generated by the four monitoring devices, and the first display screen displayed by the display device 83 first displays the third correspondingly according to the position of the monitored object. The monitoring screen generated by the monitoring device 815 is moved when the monitored object moves to the position where the second monitoring device 813 is installed according to the positional correspondence relationship between the monitoring devices (ie, in the eighth figure (f) When the asterisk moves to the right side of the display screen, the display device first displays the monitoring screen generated by the second monitoring device 813 and the third monitoring device 815, and displays the second display screen, and then gradually switches to The entire monitoring screen generated by the second monitoring device 813 further generates a third display screen.

In this way, when the user views the track of the monitored object through the display device 83, the display screen generated by the display device 83 can be generated not only according to the actual movement situation of the monitored object but also corresponding to the monitoring device displayed at each relative position. The screen can also be used to guide the monitoring screen across different monitoring devices to the screen display process of the display device, which enhances the user's appearance when viewing the display screen.

The same manner can also be applied to the case where the number of monitoring devices used by the monitoring system is the same as the number of display devices, as shown in FIG. 8(g), although the display screen displayed by each display device is initially in accordance with the monitoring device. The relative position display shows that the first display device 831 displays the monitoring screen generated by the first monitoring device 811, and the second display device 832 displays the monitoring screen generated by the second monitoring device 813, and the rest analogy.

Although the relative display position adjustment of each display screen displayed by the display device can be performed only to a small extent due to the actual installation position of the display device, the entity of the display device is applied after the monitoring screen display method of the present invention is applied. The location does not cause too much hindrance or limitation to the monitoring screen display process.

For example, the display screen initially presented by the fourth display device is monitored by the fourth monitoring device 817, but when the user starts monitoring the situation in the monitoring screen generated by the third monitoring device 815, the fourth display The display screen presented by the device 834 is correspondingly switched to the monitoring screen generated by the second monitoring device 813, and the first display device 831 and the second display device 832 also change its display screen to become the fourth monitoring device 817 and the first The monitoring screen generated by the monitoring device 811.

As shown in FIG. 8(b), in all the display devices, the relative positions of the second display device 832, the third display device 833, and the fourth display device 834 substantially conform to the first monitoring device 811 and the third monitoring device. The relative position of the 815 and the second monitoring device 813, but the relative position of the fourth monitoring device 817 is not corresponding to the display device, so the first display device 831 is used to display the monitoring generated by the fourth monitoring device 817. Picture.

Of course, in the present invention, the display device can provide a display screen presented by each monitoring device according to the positional correspondence through the corresponding relationship integrated in the control device, and the control device can be combined with the function of the display device to The host computer controls the display of the screen to display, and can also additionally increase the judgment process of the related correlation control function in the control element that controls the image output of the display device. That is, the use of the control device is to provide the corresponding display screen and the corresponding effect of the monitoring device, but in actual application, it does not mean that the control device must exist in the form of a separate device to achieve the same effect, and can be regarded as the overall monitoring. The system needs to be integrated into the display device or the monitoring device.

In addition to the relative position on the display screen according to the user's operation to perform the edit display of the display screen, the present invention can also use the method of detecting the startup mode, so that the user can set the display device to pass through when the display screen is switched. What kind of preset conditions are triggered, so that the monitoring screen generated by the other monitoring devices is started to be connected, and the content of the display screen is updated on the display device.

For example, the sensing device is also provided at the monitoring device installation location. Therefore, when the sensing device detects that the event to be tested occurs, for example, the sensing device is disposed at the door edge, and once the door is pushed open, the sensing device is triggered. Therefore, the display screen displayed by the display device is automatically switched to the monitoring screen generated by the monitoring device corresponding to the sensing device.

Furthermore, in actual application, the user can also select a certain block or line in the first display screen (for example, select a monitored object wearing a red shirt), and take out according to the relevant algorithm of image processing. The characteristics of the block are used as conditions for the automatic detection of the monitoring system, that is, the feature of the monitored object is automatically detected by using the feature, so that the display device can be corresponding to the monitoring screen of the monitoring device. Through the functions provided by the software, it automatically finds the monitoring screen generated by each monitoring device during the movement of the monitored object, and switches the display screen to the monitoring screen generated by other monitoring devices in the moving process, or as In the foregoing method, the monitoring screen of the monitoring area in which different monitoring devices overlap during the moving process is superimposed or recombined and displayed.

The method of the invention is to establish the relationship between the plurality of monitoring devices (cameras) (such as the angle, position and direction of the camera) into a set of related information modules. The control device can be used in conjunction with the display device in the monitoring system according to the association information contained in the associated information module.

Using a single preview screen and matching the user's operation, it can preview the monitoring images generated by all monitoring devices, instead of being limited to the monitoring images originally generated by individual cameras, further providing users with a more intuitive and more user-friendly preview. Operating mode. Such an operation method can be used not only when displaying a single screen display, but also by using a picture of a mother-in-picture, a multi-segment picture (quad-divided picture, a six-segment picture), or the like, and the monitoring picture proposed by the present invention can be applied. Display method. It not only makes the user's operation more convenient, but also has an outstanding effect on the need to track the monitored object in real time.

In summary, the object of the present invention is to provide a user-friendly and user-friendly operation in the monitoring system, by allowing the user to view the display by integrating the corresponding relationship between the monitoring devices in the monitoring system and their positions. When the display screen is presented by the device, the monitoring screen corresponding to the single monitoring device can be presented according to the physical movement path and position of the monitored object, and the monitoring device can be generated by multiple monitoring devices through the assistance of the application. The monitoring screen is presented on the same display screen. For example, the display screens are displayed simultaneously by dividing the window in a single display screen, or the monitoring screen generated by each monitoring device is further superimposed/synthesized, thereby allowing individual Overlapping blocks between the generated monitor images provide more detailed information.
