Description

  The present invention relates to a wearable camera system and an imaging method for imaging using a wearable camera that can be worn on, for example, a human body, worn clothes, a hat, or the like.

  In recent years, for example, in order to support the operations of police officers and guards, the introduction of wearable cameras that are used by being attached to the bodies, clothes, hats, etc. of police officers and guards has been studied.

  Here, as a prior art using a wearable camera, for example, there is a wearable surveillance camera system described in Patent Document 1. The wearable surveillance camera system disclosed in Patent Document 1 stores video and audio signals from CCD camera means and microphone means worn on the body, and date / time information signals from built-in clock means in a waist pouch attached to the body. The encoding is performed by the encoding server means, and the date / time information converted into character information is superimposed on the captured image and recorded.

  The signal processing unit 11 s 3 uses the output of the image sensor 11 s 2, and RGB (Red Green Blue) format image data or YUV (luminance (Y) / color difference (U, V)) that can be recognized by humans. A frame of data is generated, and the generated frame is output to the transmission unit 11s4.

  The transmission unit 11s4 uses the frame of the image data generated by the signal processing unit 11s3 to generate encoded data for conversion into a data format that can store and transmit the image data, and the communication I / F unit 11s5. Output to.

  The communication I / F unit 11s5 outputs (that is, a frame of image data) from the transmission unit 11s4, outputs from the microphone 11s6 (that is, audio data), or outputs from the recording switch SW1s (that is, starts / stops recording). ) Is output (transferred) to the first camera 10 via the cable CB.

  The microphone 11s6 picks up the sound around the second camera 10S (for example, the sound of the field where the police officer OF rushed) and outputs the sound data of the sound obtained by the sound collection to the communication I / F unit 11s5.

  The recording switch SW1s is a push button switch for inputting an operation instruction to start / stop recording (moving image capturing) by a pressing operation of the police officer OF. A signal related to the operation detected in the recording switch SW1s is input to the communication I / F unit 11s5. The recording start / stop operation at the recording switch SW1s is the same as the recording start / stop operation at the recording switch SW1 of the first camera 10.

  Next, description will be made regarding the addition of attribute information to video data in the first camera 10 of the present embodiment. In the wearable camera system 100, the first camera 10 is switched from the second camera 10S to the first camera 10, and the first video data is captured. The first camera 10 is switched from the first camera 10 to the second camera 10S and is captured. 2 video data, or the case where the video data accumulated by transferring the first video data and the second video data captured by both the first camera 10 and the second camera 10S to the back-end servers SV1 to SV3 is used. Suppose.

  In this case, the target video data is extracted from the stored video data based on some attribute information related to the video data, such as the type of video content, the user who took the image, the date and time, the location, etc., and played back. . If there is no attribute information in the video data, it is difficult to determine what the captured video is, and the target video data cannot be extracted. Therefore, when storing a lot of video data, add attribute information. Is required.

  In the present embodiment, classification information (Classify) indicating the type of video content is assigned as attribute information so that video data can be sorted into various types. Note that the attribute information is not limited to the classification information, and includes any information related to the recorded video data. Further, the classification information as the attribute information may have a hierarchical structure or may be categorized by a plurality of systems with different classifications.

  When the police officer OF leaves the first camera 10, the second camera 10 </ b> S, or the site captured by the first camera 10 and the second camera 10 </ b> S, and later assigns attribute information with a PC or the like in the police station, Since the police officer OF determines the type and gives the attribute information while reproducing the video data, it takes time and effort. In addition, when video data to which attribute information is not assigned is accumulated, it takes time to confirm individual video data, and much effort is required for determining the type and giving attribute information. Therefore, in the present embodiment, a configuration example is shown in which the first camera 10 can easily add attribute information immediately after recording or during recording.

  FIG. 8 is a diagram illustrating an example of the relationship between the attribute selection switch SW4 and attribute information. When the first camera 10 is used, as shown in FIG. 8, attribute information is assigned and set in correspondence with the states (contact positions) C1 to C3 of the attribute selection switch SW4. In the illustrated example, assuming that the police officer OF images the scene of the incident, a traffic accident is assigned to C1, drunk driving is assigned to C2, and overspeed is assigned to C3. In the attribute information allocation, attribute information frequently used by the police officer OF is selectively set from among a plurality of defined attribute information. The contents of the table shown in FIG. 8 (that is, information defining the relationship between the attribute selection switch SW4 and the attribute information) are stored as one piece of setting information in the EEPROM 16 of the first camera 10.

  FIG. 9 is a diagram illustrating an example of the data structure of the recording data. FIG. 10 is a diagram illustrating a first example of a recorded video list. In the first camera 10 of the present embodiment, when the recorded video data is stored in the storage unit 15, as shown in FIG. 9, meta information including attribute information related to the video data is included along with the captured video data. Generated and stored in the storage unit 15 as recorded data in which both data are associated. That is, the recording data stored in the storage unit 15 includes video data and meta information.

  When transferring the video data to the back-end servers SV1 to SV3, the first camera 10 transfers and stores the recording data including the video data and the meta information. The recorded data shown in FIG. 9 is the second video data captured by the second camera 10S when the first camera 10 is switched to the second camera 10S, and is switched from the second camera 10S to the first camera 10. If the first video data is captured by the first camera 10 when one of the first camera 10 or the second camera 10S is captured first, the other is added after the other. Includes both the first video data and the second video data captured by the first camera 10 and the second camera 10S.

  The meta information related to the video data is stored, for example, as a recorded video list shown in FIG. The meta information of the recorded video list includes event ID, time information, camera ID, user ID, recorded camera information, attribute information, and GPS information. The event ID is identification information for identifying an event to be recorded.

  In the present embodiment, the first camera 10 defines one recording operation from the start of recording to the end of recording as one event, and assigns an event ID to each recording operation event (hereinafter also referred to as a recording event). . As the event ID, a file name of video data or the like may be used. The time information is time information of each recording event, and for example, a recording start time is given. As time information, not only the recording start time but also the recording start time and recording end time, the recording start time and recording duration, the time when attribute information was given during recording, and the wearable camera used for imaging were switched You may use time, the time when the wearable camera used for imaging was added, etc.

  The camera ID is identification information for identifying each of the first camera 10 and the second camera 10S. The user ID is identification information of a police officer OF who uses the first camera 10, the second camera 10S, or both. When using the first camera 10, the second camera 10S, or both, the camera ID and the user are able to determine which individual camera was used to record the recorded video data. ID is set.

  The recorded camera information is information indicating how the first camera 10 and the second camera 10S are used and imaged by the police officer indicated by the user ID for each event ID.

  Specifically, when the event ID is “Event001”, the recording camera information is first captured by the second camera 10S, but is information indicating that the recording camera information has been switched to the first camera 10 during the same recording event. (See second → first). Therefore, when the event ID is “Event001”, the camera ID is “BWC0001” indicating the first camera 10.

  Further, when the event ID is “Event002”, the recording camera information is information indicating that the first camera 10 was first picked up, but was switched to the second camera 10S and used during the same recording event ( 1st-> 2nd reference). In this case, when the event ID is “Event001”, the camera ID is “BWC0002” indicating the second camera 10S.

  Furthermore, when the event ID is “Event003”, the recording camera information is information indicating that the first camera 10 has been captured all the time (see only the first). In this case, the camera ID is “BWC0001” indicating the first camera 10.

  Furthermore, when the event ID is “Event 004”, the recording camera information was first captured by the first camera 10, but it was changed over from the first camera 10 to the second camera 10 S during the same recording event. Information (see first camera / second camera). When the event ID is “Event004”, the attribute information “Overspeed” is added to the first video data captured by the first camera 10 on “December 2, 2014, 22:00:10”. The attribute information “Drinking driving” is given to the second video data captured by the second camera 10S at “22:10:50 on December 2, 2014”. Therefore, when the event ID is “Event004”, the camera ID is defined by both “BWC0001” indicating the first camera 10 used before switching and “BWC0002” indicating the second camera 10S used after switching. Is done.

  Even when the first camera 10 is switched to the second camera 10S or vice versa, the first camera 10 is the first video data captured by the first camera 10 or the second video data captured by the second camera 10S. It is also possible to assign different attribute information to each.

  The attribute information is classification information for identifying the type of video data. Based on the information indicating the relationship between the selection state of the attribute selection switch SW4 and the attribute information shown in FIG. 8, the attribute information addition switch SW3 by the police officer OF. And given according to the operation of the attribute selection switch SW4. The GPS information is position information indicating a place where video data is recorded. For example, current position information at the start of recording is acquired from the GPS 18 and given by the MCU 19. Each of the meta information is given by the processing of the MCU 19 at the start of recording, during recording or immediately after the end of recording, and stored in the storage unit 15 in association with the video data.

  Next, in the wearable camera system 100 of the present embodiment, one wearable camera used for 1ch recording (that is, recording using the first camera 10 or the second camera 10S) and one recorded by the wearable camera used after the switching are recorded. The operation of assigning one piece of attribute information to the recorded data will be described with reference to FIG. FIG. 11 shows an example of an operation procedure for switching one wearable camera used for 1ch recording in the wearable camera system according to the present embodiment and adding one piece of attribute information to one record data recorded by the wearable camera used after the switch. It is a flowchart to explain.

  In FIG. 11, the MCU 19 of the first camera 10 performs initial setting of the first camera 10 prior to the recording operation shown in step S12 (S11). For example, when the police officer OF is dispatched, the initial setting of the first camera 10 is performed by connecting to a PC in the police station and operating the PC to transfer various setting information (for example, camera ID and user ID). Do. As an initial setting, the MCU 19 assigns a plurality of attribute information corresponding to the assignment of a camera ID and a user ID (see FIG. 10), the activation of the attribute information assignment switch SW3 and the attribute selection switch SW4, and the selection state of the attribute selection switch SW4. (See FIG. 8).

  When the MCU 19 detects the pressing operation of the recording switch SW1 for a certain time (for example, about 1 second) by the police officer OF, the MCU 19 starts the recording operation of the image (video) captured by the imaging unit 11, and is captured by the imaging unit 11. The video data of the moving image is stored in the storage unit 15 (S12).

  Here, when the recording of the first camera 10 is not continued (S13, NO), the processing of the first camera 10 ends.

  On the other hand, when the recording of the first camera 10 is continued (S13, YES), the wearable camera for the police officer OF to capture the situation of the imaging region (for example, the site) is changed from the first camera 10 to the second camera. When switched to 10S (S14, YES), the second camera 10S starts imaging. The video data of the moving image captured by the second camera 10S is transferred to the first camera 10 via the cable CB each time the imaging by the second camera 10S is continued.

  In order to switch from the first camera 10 to the second camera 10S as the wearable camera for imaging the situation of the imaging area (for example, the site), for example, the first camera 10 being recorded by the police officer OF is connected via the cable CB. What is necessary is just to connect to the 2nd camera 10S. In addition, when the first camera 10 and the second camera 10S are already connected via the cable CB, there is no operation on the first camera 10 and the recording switch SW1s of the second camera 10S is set for a certain time. It may be pressed continuously (for example, about 1 second). In any case, in the present embodiment, the wearable camera for imaging the state of the imaging region (for example, the site) can be switched from the first camera 10 to the second camera 10S by the simple operation described above.

  On the other hand, when the police officer OF has not switched from the first camera 10 to the second camera 10S as the wearable camera for imaging the situation of the imaging area (for example, the scene) (S14, NO), the recording of the first camera 10 is performed. And the process of the first camera 10 returns to step S13. In step S12, the first camera 10 is used for recording first, and the wearable camera used for recording after switching in step S14 is the second camera 10S. It is the same. That is, in step S12, the second camera 10S may be used for recording first, and the wearable camera used for recording after switching in step S14 may be the first camera 10.

  After the recording of the second camera 10S is started, the MCU 19 detects the selection state of the attribute selection switch SW4 of the first camera 10 (S15), and determines whether or not the attribute information addition switch SW3 is input (S15).

  When there is an input from the attribute information addition switch SW3 (S16, YES), the MCU 19 reads the attribute information corresponding to the selection state of the attribute selection switch SW4 from the EEPROM 16, and the second video imaged by the second camera 10S. It is given to the data (S17). The MCU 19 outputs the meta information including the assigned attribute information to the storage unit 15 and stores the meta information in association with the stored video data after finishing the recording operation immediately before (S18). In the present embodiment, attribute information is provided for the second video data captured by the second camera 10S by the operation of the police officer OF with respect to the first camera 10 while the second camera 10S is capturing an image. The attribute information may be assigned to the second video data after the second camera 10S finishes imaging, and so on.

  The meta information includes event ID, time information (for example, time when imaging by the second camera 10S is started when the wearable camera is switched), camera ID, user ID, and recording camera information (for example, used for 1ch recording). Wearable camera information), attribute information, and GPS information (see FIG. 10). Thereby, the operation of the wearable camera system 100 of the present embodiment ends.

  In the above example, the attribute information corresponding to the state of the attribute selection switch SW4 is assigned from the attribute information previously assigned to the attribute selection switch SW4. It is also possible to give attribute information corresponding to the voice uttered.

  Thus, in the wearable camera system 100 of the present embodiment, the first camera 10 and the second camera 10S that can be worn by the user (for example, a police officer OF) are used, and the first camera 10 captures an image of the first camera 10. The first video data is stored in the storage unit 15. The second camera 10 </ b> S transmits the second video data captured by the second camera 10 </ b> S to the first camera 10 when switched from the first camera 10 to the second camera 10 </ b> S. When the first camera 10 is switched from the first camera 10 to the second camera 10S and picks up an image, the first camera 10 receives the second video data transmitted from the second camera 10S, and assigns attribute information related to the second video data. Is received, attribute information is assigned to the second video data and stored in the storage unit 15 according to the giving operation, and the first video data captured by the first camera is deleted from the storage unit.

  As a result, the wearable camera system 100 switches the image from the first camera 10 to the second camera 10S in order to accurately and extensively capture the situation of the scene where the user (for example, police officer OF) rushed in an emergency. Deletes the first video data that is no longer required by the switching, and the second video data is obtained by a simple operation on the first camera 10 alone with respect to the second video data captured by the second camera 10S used after the switching. Attribute information indicating what kind of video is. Therefore, the wearable camera system 100 can support accurate and wide-ranging imaging of the situation of the site by the user (for example, police officer OF), and further improves convenience in handling the captured video data (second video data). Can be made.

  In the wearable camera system 100 of the present embodiment, when the second camera 10S is switched from the second camera 10S to the first camera 10 and captured, the second video captured until the first camera 10 is switched. Data is transmitted to the first camera 10. When the first camera 10 is switched from the second camera 10S to the first camera 10 and captured, the first camera 10 receives the second video data transmitted from the second camera 10S and receives the second video data transmitted from the second camera 10S. When the video data is discarded and an operation for giving attribute information related to the first video data is accepted, the attribute information is given to the first video data and stored in the storage unit 15 according to the giving operation.

  As a result, the wearable camera system 100 switches from the second camera 10 </ b> S to the first camera 10 in order to accurately and extensively capture the situation at the scene where the user (for example, a police officer OF) rushed in an emergency. Discards the second video data that is no longer required by switching, and the first video data is obtained by a simple operation on the first camera 10 alone with respect to the first video data captured by the first camera 10 used after switching. Attribute information indicating what kind of video is. Therefore, the wearable camera system 100 can support accurate and wide-ranging imaging of the situation in the field for the user (for example, police officer OF), and further improves the convenience in handling the captured video data (first video data). Can be made.

  For this reason, even if the user (for example, a police officer OF) is an imaging site in an emergency, the user can switch the first camera 10 and the second camera 10S as appropriate to capture the first image used for switching after switching. The attribute information of the first video data captured by the first camera 10 or the second video data captured by the second camera 10S can be reliably given. In addition, since the first video data or the second video data captured before switching is deleted or discarded in the first camera 10, an increase in the storage capacity of the first camera 10 can be avoided. Further, when using video data stored in a server arranged in a back-end system of a police station, a user (for example, a user of the back-end system) refers to attribute information given to the video data. Therefore, it is possible to easily identify and extract which type of video data, and by using meta information including attribute information, when, where, and by what camera, what kind of content is captured Can be easily identified.

  In the present embodiment, the wearable camera used for imaging in the imaging region (for example, the field) may be switched from one to the other of the first camera 10 or the second camera 10S, or one of the wearable cameras (for example, the first camera in advance). In the state of being imaged by the camera 10), it may be added later and imaged by the other wearable camera (for example, the second camera 10S) (see FIGS. 12 and 13). FIG. 12 is a diagram illustrating a second example of the recorded video list. In the description of FIG. 12, the description of the same content as the description of FIG. 10 is omitted, and different content is described. In the recorded video list shown in FIG. 12, a portion different from the recorded video list shown in FIG. 10 is recorded camera information.

  Specifically, when the event IDs are “Event001” and “Event003”, the recording camera information is information indicating that the first camera 10 has been captured all the time (see only the first). In this case, the camera ID is “BWC0001” indicating the first camera 10.

  Further, when the event ID is “Event002”, the recording camera information is information indicating that the first camera 10 was first imaged, but the second camera 10S was added and used for imaging (first image). (See 1 camera + 2nd camera). In this case, when the event ID is “Event002”, the camera ID is “BWC0001 + BWC0002” indicating the first camera 10 and the second camera 10S.

  In addition, when the event ID is “Event004”, the recording camera information was first imaged by the first camera 10, but information indicating that the second camera 10S was added and used for imaging during the same recording event. (Refer to the first camera / first camera + second camera). When the event ID is “Event004”, the attribute information “Overspeed” is added to the first video data captured by the first camera 10 on “December 2, 2014, 22:00:10”. , The attribute information “Drinking driving” is included in the first video data captured by the first camera 10 and the second video data captured by the second camera 10S at “22:10:50 on December 2, 2014”. Is granted. Therefore, when the event ID is “Event004”, the camera ID is “BWC0001” indicating the first camera 10 used before the addition, “BWC0001” indicating the first camera 10 used after the addition, and the second camera 10S. Both “BWC0001 + BWC0002” indicating a combination with “BWC0002” indicating “BWC0002” are defined.

  Note that even when the second camera 10S is added after the first camera 10 captures the image first, or vice versa, the first camera 10 captures the first video data and the second image captured by the first camera 10. It is also possible to give different attribute information to the second video data imaged by the camera 10S.

  Next, in the wearable camera system 100 of the present embodiment, the wearable camera used for simultaneous 2ch recording (that is, recording using the first camera 10 and the second camera 10S) is switched, and two recorded data recorded simultaneously 2ch are recorded. An operation for assigning common attribute information to the apparatus will be described with reference to FIG. FIG. 13 shows an example of an operation procedure for switching to simultaneous 2ch recording in the wearable camera system 100 of the present embodiment and for assigning common attribute information to recording data recorded by each wearable camera used for simultaneous 2ch recording. It is a flowchart explaining these. In the description of FIG. 13, description of contents overlapping with the description of FIG. 11 is simplified or omitted, and different contents are described.

  In FIG. 13, after step S <b> 12 (that is, in a state where video is recorded by the first camera 10), the police officer OF adds a wearable camera for imaging the situation of the imaging area (for example, the scene). When the second camera 10S and the first camera 10 are connected via CB (S21, YES), the second camera 10S starts imaging. At this time, the first camera 10 that was first used for imaging may stop imaging according to the addition of the second camera 10S, or may continue imaging. The video data of the moving image captured by the second camera 10S is transferred to the first camera 10 via the cable CB.

  When there is an input from the attribute information addition switch SW3 (S16, YES), the MCU 19 reads the attribute information corresponding to the selection state of the attribute selection switch SW4 from the EEPROM 16, and the second camera 10S transfers to the first camera 10. Attribute information common to the first video data of the moving image captured by the first camera 10 and the second video data of the moving image captured by the second camera 10S until they are connected (in the selection state of the attribute selection switch SW4). (Corresponding attribute information) is assigned (S22).

  After step S22, the MCU 19 outputs meta information including common attribute information to the storage unit 15, and stores the meta information in association with the stored video data immediately after the recording operation (S23). The meta information includes event ID, time information (for example, the time when imaging by the second camera 10S is started when a wearable camera is added), camera ID, user ID, and recording camera information (for example, for simultaneous 2ch recording). Wearable camera information), attribute information, and GPS information (see FIG. 12). Thereby, the operation of the wearable camera system 100 of the present embodiment ends.

  As described above, in the wearable camera system 100 of the present embodiment, the first camera 10 stores the first video data captured by the first camera 10 in the storage unit 15. The second camera 10S captures the second video data captured by the second camera 10S in the first camera 10 when the first camera 10 captures the image first and when the second camera 10S starts capturing the image later. Send. The first camera 10 receives the second video data transmitted from the second camera 10S when the first camera 10 picks up the image first and the second camera 10S starts to pick up the first video. When an operation for giving attribute information related to the data and the second video data is received, common attribute information is given to the first video data and the second video data and stored in the storage unit 15 according to the giving operation.

  As a result, the wearable camera system 100 captures images using not only the first camera 10 but also the second camera 10S in order to accurately and extensively capture the situation of the scene where the user (for example, a police officer OF) rushed in an emergency. When started, the first camera 10 alone is simplified for both the first video data originally obtained by imaging and the second video data taken by the second camera 10S used for later imaging. Through common operation, common attribute information indicating what kind of video the first video data and the second video data are can be given. Therefore, the wearable camera system 100 can support accurate and wide-ranging imaging of the situation in the field by the user (for example, police officer OF), and further, when handling the captured video data (first video data and second video data). Convenience can be improved.

  Further, in the wearable camera system 100 of the present embodiment, when the second camera 10S is imaged first by the second camera 10S and imaging by the first camera 10 is started, imaging by the first camera 10 is performed. The second video data captured by the second camera 10S before the start is transmitted to the first camera 10. The first camera 10 receives the second video data transmitted from the second camera 10 </ b> S when the first camera 10 </ b> S is imaged first and the first camera 10 starts imaging, and the first camera 10 When an operation for giving attribute information related to the first video data and the second video data captured by 10 is received, common attribute information is given to the first video data and the second video data in accordance with the giving operation, and the storage unit 15. To remember.

  As a result, the wearable camera system 100 captures images using not only the second camera 10S but also the first camera 10 in order to accurately and extensively capture the situation of the scene where the user (for example, a police officer OF) rushed in an emergency. When started, the first camera 10 alone is simplified with respect to both the second video data originally obtained by imaging and the first video data taken by the first camera 10 used for later imaging. Through common operation, common attribute information indicating what kind of video the first video data and the second video data are can be given. Therefore, the wearable camera system 100 can support accurate and wide-ranging imaging of the situation in the field by the user (for example, police officer OF), and further, when handling the captured video data (first video data and second video data). Convenience can be improved.

  For this reason, a user (for example, a police officer OF) takes an image using both of the first camera 10 and the second camera 10S even from an imaging site in an emergency. Thus, the video data (for example, the first video data) captured by one camera (for example, the first camera 10) used for the original imaging and the other camera (for example, the second camera 10S) used for the subsequent imaging. ) Can be reliably attached to the attribute information common to the video data (for example, the second video data) captured. In addition, when using video data stored in a server arranged in a back-end system of a police station, a user (for example, a user of the back-end system) gives to the first video data and the second video data. By referring to the common attribute information, it is possible to easily identify and extract the type of each video data, and further, when, where, by which camera by meta information including attribute information It is possible to easily identify who captured the image and what kind of content it is.

  In addition, the wearable camera system 100 can easily assign the attribute of the video data by the first camera 10 by a simple operation of the user (for example, police officer OF). The video data can be easily identified immediately after.

  Also, the first camera 10 accepts an attribute information assignment operation related to the first video data or the second video data at the attribute information assignment switch SW3, accepts an attribute information selection state designation operation at the attribute selection switch SW4, and selects an attribute. Attribute information corresponding to the selection state of the switch SW4 is given to the first video data, the second video data, or both. Thereby, the first camera 10 gives the attribute information selected by the attribute selection switch SW4 to the first video data, the second video data, or both by the operation input of the attribute information addition switch SW3. The operation of giving attribute information can be simplified by a simple operation of the user (for example, police officer OF) on the first camera 10 alone. Therefore, the 1st camera 10 can reduce the effort at the time of attribute information provision with respect to a user (for example, police officer OF), and can identify video data simply from immediately after recording.

  In the first camera 10, different attribute information is assigned to a plurality of selection states in the attribute selection switch SW4. Accordingly, the first camera 10 can selectively determine attribute information desired by the user (for example, police officer OF) from among a plurality of attribute information by operating the attribute selection switch SW4. Appropriate attributes can be assigned to video data or both.

  In the wearable camera system 100 of the present embodiment, when the first camera 10 and the second camera 10S are connected via the cable CB, one of the first camera 10 and the second camera 10S (for example, the first camera 10S).
