This indicates that image data captured in a state where v ₂ ′ and “zoom focal length” are z ₂ ′ are stored in an area where the area number of the image data storage area 116 a is “r ₂ ”.

  Next, a procedure for copying the preset position information of the existing monitoring camera apparatus 200 according to the embodiment of the present invention to the new monitoring camera apparatus 100 will be described. FIG. 4 is a flowchart showing a procedure for copying the preset position information of the existing monitoring camera device 200 to the new monitoring camera device 100.

  First, in step S <b> 10, the user requests to copy the preset position information of the existing monitoring camera device 200 to the new monitoring camera device 100 from the operation unit 304 of the personal computer device 300.

  In step S <b> 20, when the operation unit 304 of the personal computer device 300 notifies the control unit 302 of a copy request for preset position information of the existing monitoring camera device 200 to the new monitoring camera device 100, the control unit 302 of the personal computer device 300 causes the control unit 302. Then, a transmission request for preset position information is made to the existing monitoring camera device 200.

  In step S30, when the existing monitoring camera device 200 receives a transmission request for preset position information from the personal computer device 300, the control unit 204 of the existing monitoring camera device 200 reads the preset position from the preset position information table 205a of the nonvolatile memory 205. Is transmitted to the newly installed monitoring camera apparatus 100 via the communication unit 201. Further, the digital signal processing circuit (DSP) 202 of the existing monitoring camera device 200 extracts image data from the image data storage area 203 a of the memory IC 203 and transmits it to the new monitoring camera device 100 via the communication unit 201.

  In step S40, when the newly installed monitoring camera apparatus 100 receives the preset position and image data via the communication unit 117, the control unit 118 displays the preset position received via the digital signal processing circuit (DSP) 115. , Copy to the preset position information table 119a of the nonvolatile memory 119. The digital signal processing circuit (DSP) 115 copies the received image data to the image data storage area 116a of the memory IC 116a.

  Next, in step S50, the control unit 118 of the newly installed monitoring camera apparatus 100 causes the preset position registration processing unit 118a to start preset position registration processing.

  Next, preset position registration processing of the newly installed monitoring camera apparatus 100 according to the embodiment of the present invention will be described. FIG. 5 is a flowchart showing preset position registration processing of the newly installed monitoring camera apparatus 100.

  First, in step S100, the preset position registration processing unit 118a sets an initial value “1” to the index No (I) in order to extract the preset position from the preset position information table 119a of the nonvolatile memory 119.

Next, in step S110, the preset position registration processing unit 118a extracts the “horizontal orientation” of the index No (I) from the preset position information table 119a and outputs it to the horizontal rotation unit 123. When the “horizontal orientation” is input, the horizontal rotation unit 123 rotates the camera platform 103 in the “horizontal orientation”. For example, as shown in FIG. 3A, if the index No (I) is “2”, the “horizontal direction” of the index No (I) is h ₂ , so the horizontal rotation unit 123 is based on the pan head 103. It is rotated horizontally from the position to the position of h _2.

Next, in step S 120, the preset position registration processing unit 118 a extracts the “vertical direction” of the index No (I) from the preset position information table 118 a and outputs it to the vertical rotation unit 124. When the “vertical direction” is input, the vertical rotation unit 124 rotates the camera platform 103 in the “vertical direction”. For example, as shown in FIG. 3A, if the index No (I) is “2”, the “vertical direction” of the index No (I) is v ₂ , so the vertical rotation unit 124 is based on the pan head 103. rotate vertically from the position to the position of v _2.

Next, in step S130, the preset position registration processing unit 118a extracts the “zoom focal length” of the index No (I) from the preset position information table 118a, and outputs it to the zoom lens unit 111 via the camera module unit 114. When a zoom focal length is input, the zoom lens unit 111 moves the zoom lens so that the zoom focal length is reached. For example, as shown in FIG. 3A, if the index No (I) is “2”, the “zoom focal length” of the index No (I) is z ₂ , so the zoom lens unit 111 has a zoom focal length. moving the zoom lens such that z _2.

Next, in step S140, the preset position registration processing unit 118a takes out the “area number of the image data storage area” of the index No (I) from the preset position information table 119a. The preset position registration processing unit 118a also stores the image data of the real-time video signal output from the camera module unit 114 and the preset position of the existing monitoring camera device 200 stored in the image data storage area 116a of the memory IC 116 in step S140. In order to request the digital signal processing circuit 115 to determine whether or not the image data match, the extracted “area number of the image data storage area” is output to the digital signal processing circuit 115, and the digital signal processing circuit Wait for a response from 115. For example, as shown in FIG. 3A, if the index No (I) is “2”, the “image data storage area area No” of the index No (I) is r _2. R ₂ is output to.

  In step S150, the digital signal processing circuit 115 extracts image data from the real-time video signal output from the camera module unit 114. Further, the digital signal processing circuit 115 takes out the image data of the preset position of the existing monitoring camera device 200 stored in the “image data storage area No” from the image data storage area 116 a of the memory IC 116. The digital signal processing circuit 115 compares the image data of the real-time video signal with the image data of the preset position of the existing monitoring camera device 200, and outputs the comparison result to the preset position registration processing unit 118a.

  Next, in step S160, the preset position registration processing unit 118a inputs the result of comparing the image data of the real-time video signal and the image data of the preset position of the existing monitoring camera device 200 from the digital signal processing circuit 115, and they match. It is determined whether or not. When the image data of the real-time video signal and the image data of the preset position of the existing monitoring camera device 200 match (Yes in step S160), the “horizontal orientation” and “vertical orientation” of the current new surveillance camera device 100 ”And“ Zoom focal length ”are set in the preset position information table 119a, the process proceeds to step S200. If the image data of the real-time video signal and the image data of the preset position of the existing monitoring camera device 200 do not match (No in step S160), the process proceeds to step S170 for finely adjusting the horizontal direction of the camera platform 103. .

  Next, in step S170, the preset position registration processing unit 118a performs a horizontal fine adjustment with respect to the horizontal rotation unit 123 in order to match the image data of the real-time video signal with the image data of the preset position of the existing monitoring camera device 200. Make adjustments.

  Next, in step S180, the preset position registration processing unit 118a performs fine adjustment in the vertical direction with respect to the vertical rotation unit 124 in order to match the image data of the real-time video signal with the image data of the preset position of the existing monitoring camera device 200. Make adjustments.

  In step S190, the preset position registration processing unit 118a passes the camera module unit 114 and the zoom lens unit in order to match the image data of the real-time video signal with the image data of the preset position of the existing monitoring camera device 200. The zoom lens is moved with respect to 111 to finely adjust the zoom focal length.

Next, in step S200, the preset position registration processing unit 118a sets the "horizontal orientation", "vertical orientation", and "zoom focal length" of the current newly installed surveillance camera device 100 as an index of the preset position information table 119a in the nonvolatile memory 119. Set to “horizontal orientation”, “vertical orientation”, and “zoom focal length” corresponding to No (I). For example, if the index number (I) is “2”, the “horizontal orientation” of the current newly installed surveillance camera device 100 is h ₂ ′, the “vertical orientation” is v ₂ ′, and the “zoom focal length” is z ₂ ′. For example, as shown in FIG. 3 (2), h ₂ ′ in the “horizontal direction”, v ₂ ′ in the “vertical direction”, and z ₂ ′ in the “zoom focal length” in the index number “2” of the preset position information table 119a. Is set.

Next, in step S210, the preset position registration processing unit 118a stores the current image data of the newly installed monitoring camera device 100 in the image data storage area 116a of the memory IC 116 via the digital signal processing circuit (DSP) 115. The area number of the image data storage area 116a for storing the image data is the “area number of the image data storage area” output from the preset position registration processing unit 118a to the digital signal processing circuit (DSP) 115 in step S140. For example, if the index No (I) is "2", since "area of the image data storage area No" preset positions information table 119a as shown in FIG. 3 (2) is a r _2, image data is image The data is stored in the area Nor ₂ of the data storage area 116a.

  Next, in step S220, the preset position registration processing unit 118a adds “1” to the index No (I) in order to register the next preset position.

  Next, in step S230, the preset position registration processing unit 118a determines whether the index No (I) is larger than the registration number “n”. When the index number (I) is larger than the registered number “n” (Yes in step S230), all preset positions of the newly installed monitoring camera device 100 are set in the preset position information table 119a, and thus the preset position registration process is terminated. To do. Further, when the index No (I) is not larger than the registered number “n” (No in step S230), not all preset positions of the newly installed monitoring camera device 100 are registered in the preset position information table 119a. The position registration processing unit 118a returns to step S110.

  As described above, in the embodiment of the present invention, the preset positions and the image data of the horizontal direction, vertical direction, and zoom focal length of the existing monitoring camera device are copied to the new monitoring camera device, and the preset position of the existing monitoring camera device is set. In the above embodiment, the horizontal position, the vertical direction, and the zoom focal length preset position adjusted so as to match the image data of the new monitoring camera apparatus and the preset position of the new monitoring camera apparatus are registered in the new monitoring camera apparatus. In addition, it is also possible to perform preset position registration for retrograde correction for adjusting the exposure of the monitoring camera device.

  In the embodiment of the present invention, the preset position information is copied from one existing surveillance camera device to one new surveillance camera device. It is also possible to copy the preset position information to a new monitoring camera device.

In step S302, the management terminal 350 makes a transmission request for the pan head setting information to each of the existing cameras 200 to be transplanted based on the specific information, and each preset transmitted from the existing camera 200 as a response thereto. The position PTZ (pan (horizontal direction), tilt (vertical direction), zoom) and image data and image data are received to form preset position information, which is stored in the memory in the management terminal 350. Also, the pan head definition information (accuracy (minimum drive unit), turning speed, operating range, etc.) received together is stored.
The pan head setting information and the pan head definition information correspond to the PTZ service and PTZ Configuration of the PTZ service in ONVIF. The transmission request for the setting information can also be made with the GetSystemBackup command if the existing camera 250 also supports ONVIF.

Next, in step S303, the worker removes the existing camera 250 from the IP network 500 and connects the corresponding new camera 150 instead. The new camera 150 is placed on a stand (with four bolt holes opened) where the existing camera 250 was installed. In this case, the direction that serves as a reference for the absolute angle of the pan is the existing camera 250 and the new camera. Pay attention to the mounting direction so that it is equal to 150.
The new camera 150 is a non-volatile storage of unique values (SerialNumber in UUID and Device Information) that does not overlap with any other devices including existing cameras, and information on the performance and functions of its own hardware (device scope parameter). Stored in the memory 119.
After the replacement work, the worker instructs the management terminal 350 to set a new camera as necessary.

Next, in step S304, the management terminal 350 recognizes the new camera 150 in accordance with the setting instruction or by detecting a change in the camera with a periodically performed probe. The simplest method of recognition is a method in which the corresponding existing camera 250 and new camera 150 continue to use the same IP address, and the operator manually instructs the setting.
Another method is to give the management terminal 350 a list that associates the unique value of the new camera with the specific information (camera ID) of the existing camera in advance, or sets the new camera as a Scope parameter with specific information or attributes unique to the factory shipment. By giving a value, only a new camera connected to the IP network is extracted by the probe, and if possible, the existing camera 250 and the new camera 150 having the same specific information and the like are associated with each other. For example, the UUID is included in the Probe response, and the SerialNumber is included in the GetDeviceInformationResponse response. General initial settings (system clock and IP network settings, scope parameters) may be performed during or before this step.

  Next, in step S305, the management terminal 350 tries association by image matching for the new camera 150 that could not be associated in S305. First, using the AbsoluteMove command of ONVIF's PTZ service, etc., the pan / tilt of the new camera 150 can be used for the PTZ indicated by any preset position information (stored in S302) of one existing camera that could not be associated. Control to be in a state. After that, specify an arbitrary Media profile (ready-to-use-profile prepared by default) and send the get method of http to the URI acquired by GetSnapshotUriRequest, and the new camera 150 was photographed as the response Receive still images. Then, the position and magnification at which the degree of coincidence is maximized are searched for while relatively shifting or enlarging / reducing the received still image and the image data corresponding to the preset position information within a predetermined range. When the maximum matching degree is less than the predetermined value, it is determined that the new camera 150 does not correspond to the existing camera, and similar association is tried for other existing cameras that could not be associated.

  In step S306, the management terminal 350 sets a desired media profile in the new camera 150 prior to transplanting the preset position information. The media profile is defined for each setting condition such as the video size (number of pixels) and the frame rate. Thereafter, the client terminal 400 requests the video by designating the media profile. The next PTZ setting is also included in the Media profile.

  Next, in step S307, the management terminal 350 transplants the stored preset position information according to the correspondence found in S304 and S305. The management terminal 350 acquires a PTZ node token from the new camera 150 using the GetNodesRequest command of the PTZ service. The node token is a unique ID of the PTZ node, and usually one surveillance camera (head) has one PTZ node token. Next, the PTZ Configuration is acquired by the GetConfiguration command designating the node token, and the PTZ of the preset position information is converted so as to conform to the coordinate space indicated by the PTZ Configuration as necessary. Next, the imaging direction of the new camera 150 is directed to the Position by an AbsoluteMoveRequest command specifying the Media profile and Position (PTZ of preset position information). Next, the current Position is set in the new camera 150 by a SetPresetRequest command specifying Node token, Media profile, and optionally PresetToken (preset position information index No.) or PresetName. When PresetToken is specified, the existing setting of the PresetToken is overwritten. When PresetToken is not specified, a unique value newly assigned as PresetToken is returned. This operation is repeated for the number n of the index numbers. Note that one of the preset positions may be set as a home position instead of a preset. When there are a plurality of media profiles, preset position information is similarly set for each of the media profiles. In the case of a pan head camera that cannot use the AbsoluteMove command, the RelativeMoveRequest command is operated from the initial PTZ position after reset (power-on).

  In step S308, the preset position information that has been set is finely adjusted. First, the pan head of the new camera 150 is operated by a GotoPresetRequest command specifying Media profile and PresetToken. After that, as in S305, the latest image captured by the PTZ at the preset position is received by transmitting a get method of http to the URI acquired by GetSnapshotUriRequest. Then, the position and magnification at which the degree of coincidence is maximized are searched for while relatively shifting or enlarging / reducing the received image and the image data corresponding to the preset position information stored in S302 within a predetermined range. Then, according to the position and magnification, PTZ (that is, the angle of view) is finely adjusted by RelativeMoveRequest specifying Translation (relative movement amount of position). Then, the latest image is acquired again and the maximum matching degree is searched. The above operation is repeated until the difference from the previous degree of coincidence falls below a predetermined value or the number of searches reaches a predetermined upper limit.

  Finally, in step S309, the current position is overwritten by the SetPresetRequest command. The position at that time can be acquired by a GetStatusRequest command, and fine adjustment of other preset position information can be simplified using the difference from the original preset position information stored in S302.

  The processing from step S306 to S309 can be performed sequentially or in parallel on m cameras. In the above example, each preset position information itself has been modified. However, if the PTZ offset can be set in PTZ Configuration, the above difference is set in the offset, and the offset is added to the position specified in AbsoluteMoveRequest. You may do it.

  In addition to the preset position, backlight correction and the like can be reproduced by using image data that has been captured and stored in advance at the preset position. The method will be described below. Note that the image data is a captured image when the existing camera 250 is manually corrected for backlighting, and it is desirable that the date and time or the imaging conditions such as exposure and iris at that time are also stored. In addition, it is desirable that the Imaging configuration is transplanted in advance like the preset position by using the SetImagingSettingsRequest command. In ONVIF, BacklightCompensation, Brightness, ColorSaturation, Sharpness, Contrast, Exposure, Focus, Ir cut filter, Whitebalance, and WideDynamicRange are defined as setting items of Imaging configuration.

  First, in step S401, after the completion of S309, the process waits until the same time as the date and time stored in the image data. This is because the comparison is performed with the same illuminance as when the stored image data was captured. In addition to the date and time, the illuminance can be calculated back from the exposure and iris, and the exposure and iris can be obtained by GetStatusRequest of Imaging service at ONVIF.

  In step S402, the management terminal 350 receives a still image captured by the new camera 150 using GetSnapshotUri or the like, as in step S305. At almost the same time, the GetStatusRequest of Imaging service is used to obtain exposure and iris information. Then, if it is significantly different from the exposure and iris included in the image data, the subsequent processing is stopped.

In step S403, the management terminal 350 creates a luminance histogram for each of the received still image and stored image data corresponding to the preset position information.
Then, a relative position where the correlation between both shapes is maximized is obtained by ignoring a portion having a predetermined luminance (for example, 80%) or more. Instead of the maximum correlation position, a difference in the peak position of the histogram may be used. When the obtained relative position size (shift on the histogram) is a predetermined value or more, it is considered that Brightness, Contrast, Exposure, etc. do not match the existing camera 250, and these settings are readjusted.
If the relative position is less than or equal to a predetermined value, each of the histograms is divided into at least a high luminance region, a medium luminance region, and a low luminance region, and the area of the medium luminance region and low luminance region on the histogram is determined. Find the ratio. The high brightness area is not particularly used. Instead of the area ratio, the ratio of the maximum values in each region may be used.
Then, the ratio (or difference) of the ratios obtained from both histograms is obtained.

In step S404, the management terminal 350 corrects the value of BacklightCompensation according to the ratio (difference). In other words, the current BacklightCompensation is obtained by GetImagingSettingsRequest specifying the video source. For example, the value of BacklightCompensation is increased by one, and the correction is reflected on the new camera 150 by SetImagingSettingsRequest.
The operations in S403 and S404 are repeated until the ratio (difference) falls within a predetermined range or the number of corrections reaches a predetermined upper limit.
