Patent Document 1: JP-A-5-334572

  However, although it is possible to distribute video to a remote point in real time, it is necessary to provide a video device and a video distribution device for each event, so that it is expensive to construct a remote point distribution system was there.

  Moreover, even if video equipment and a video distribution device are obtained at a low price, there is a problem that it takes time to construct the system because the system must be manually constructed for each event venue.

  Therefore, it is desirable that even if the event venue is changed, the contents of the event can be taken and broadcast immediately and at no cost.

  Further, a tracking camera 20 (dome camera) is fixed to the lower surface of the top plate 10, and a wide-angle camera 21 is fixed to the lower surface of the top plate 11 behind the top plate 10.

  FIG. 2 is a top view of the apparatus. FIG. 3 is a front view. FIG. 4 is a side view.

  As shown in FIGS. 2, 3, and 4, the tracking camera 20 is fixed under the top plate 10, and the wide-angle camera 21 has a field of view in a certain direction by a camera support bracket 23 under the back top plate 11. So that it is fixed. The wide-angle camera 21 is preferably attached so that the tracking camera 20 is not viewed.

  The interval between the top plate 10 and the top plate 11 is set to have an interval of about several centimeters.

  Further, a bracket 25 is provided on the top surface of the top plate 10, and the tracking camera 20 can be fixed by the bracket 25 and can be moved to the left and right. That is, the tracking camera 20 can be moved left and right.

(Configuration of each part)
The tracking camera 20 (dome camera) has a dome-like outer shape and includes a camera unit (not shown) inside, and a drive unit for panning and tilting the camera unit is built in the base, and the back side of the top plate 10 It is fixed with a bracket 25.

  That is, both cameras are provided on the ceiling or the like in a predetermined positional relationship so as not to capture each other's images.

  The tracking camera 20 and the wide-angle camera 21 are connected to the automatic tracking device 17 and controlled by the camera controller 14.

  The tracking image obtained by the automatic tracking device 17 and the image of the wide-angle camera 21 are stored in the image storage device 16 and are transmitted to the server 18 (with a monitor and an operation board) to be sent to an external terminal via the Internet 27. 28.

  Next, the configuration of the automatic tracking device 17 will be described. FIG. 5 is a schematic configuration diagram of the automatic tracking device 17 of the present embodiment.

As shown in FIG. 5, the automatic tracking device 17 detects a moving object (student, teacher,..., Etc .: also referred to as a target) of a wide-area image captured by the wide-angle camera 21 with a motion detection unit 30. The video detected by the motion detection unit 30 is cut out and recognized as a target, and the tracking camera control unit 32 outputs a zoom-in video and a zoom-out video while tracking based on the tracking position information of the target.

  The motion detector 30 converts the photoelectrically converted output signal of the wide-angle camera 21 into a digital image signal, stores it in the first frame memory, and stores the image stored in the second frame memory (for the previous image). The pixel value (for example, luminance) of each pixel is calculated for each pixel, and a pixel having a large difference (absolute value) is set to “1” and a small pixel is set to “0” (this is the motion detection image and this embodiment). (Referred to in the form). For the above-described motion detection, a motion detection area, a mask area, and the like are set in advance, and a target is detected in the motion detection area.

  The target tracking unit 31 cuts out an “island (connected region)” of a pixel having a value “1” from the motion detection image, and recognizes this as a new target when the cut-out target exists in a preset sense area. . Then, a symbol code for the cut target (symbol code including coordinates estimated to be present: tracking position information) is generated (tracking). When it is recognized as a new target, a zoom-in signal having a predetermined zoom ratio is generated and output. However, just before the system is started, only one target is detected. Thereafter, when multiple targets are detected, a symbol code (also referred to as tracking position information) is output to the multiple target range tracking setting unit.

  When the target stops moving, the target tracking stop signal (including the symbol code) is output to zoom in.

  As shown in FIG. 6, the multiple target range tracking setting unit 33, for example, in the order of the second target and the third target instead of the first target in the sense area (for example, when three are detected), Tracking position information is determined on a straight line connecting the gravity center positions of the image areas of the second and third targets, and the tracking position information is output to the tracking camera control unit 32.

  As shown in FIG. 6, in addition to the first target (teacher), for example, symbol codes (two) indicating the second target (student) and the third target (student) are input from the target tracking unit 31 to the sense area. Then, the second target and the third target corresponding to this symbol code are allocated. That is, the first target (teacher) is excluded.

  Then, the center of gravity of the second target and the third target is determined, the distances (L1, L2) from both ends of the sense area to the center of the second target and the third target are obtained, and the sense area length L to L1, A horizontal range is determined by subtracting L2 and adding a predetermined length m. Then, a range Gi of a predetermined height h is obtained, and the center (center portion) of this range is set as the tracking position. That is, the tracking point of the range Gi is determined on a straight line connecting the centroids of the second and third targets.

  The target tracking unit 31 outputs tracking information including the range Gi and the tracking point (coordinate position) to the tracking camera control unit 32. Further, when one target is detected and the target stops moving, a target tracking stop signal (including a symbol code) is output.

  The tracking camera control unit 32 stores the tilt angle, pan angle, zoom ratio, and the like of the tracking camera 20 and controls the tilt angle and pan angle based on the tracking information each time the tracking information is input, so that the target is The zoom ratio is controlled so as to be within the viewing angle of the tracking camera 2 and to capture the range Gi. In this control, each angle and speed are controlled so as to achieve a target angle.

  The video superimposing unit 33 superimposes the wide-angle camera video and / or tracking camera video from the wide-angle camera 21 and outputs the video to the image storage device 16 and the server 18.

  The server 18 has an operation unit, a monitor, and an Internet connection function, and provides the aforementioned wide-angle camera image, tracking camera image, or superimposed image to a preset member.

  Further, the server 18 stores the mode table shown in FIG. 8, and the operator displays a mode selection screen (see FIG. 7) corresponding to the mode table, and sets the conditions of the selected mode in each unit.

(Description of operation)
Since the movable mobile imaging device of the present embodiment is equipped with casters, the teacher's assistant is brought to the classroom before the start of the lesson and performs the operations described below.

  At this time, the assistant activates the wide-angle camera 21 and adjusts with the telescopic pole whether the platform side is properly viewed while looking at the monitor of the server. Further, the server and the network are connected so that video can be provided to the viewer terminal 28 at the remote location.

  FIG. 9 is a flowchart for explaining the operation of the system according to the present embodiment.

  The CPU (not shown) of the automatic tracking device 17 internally sets the memory motion detection area, the sense area, the mask area, and the matrix of the mode table selected from the server 18 when the system is turned on (S901). . The above-described CPU controls the motion detection image of each unit, target cutout, tracking, zoom-in, and zoom-out timing.

  The motion detection area, sense area, and mask area will be described with reference to FIG. In the present embodiment, it is assumed that the audiovisual mode at school is selected.

As shown in FIG. 10, each area of the audiovisual mode includes a motion detection area for detecting and tracking the movement of a moving body (student, teacher) on the platform side, and zooming in and zooming out by recognizing the target. , And a sense area for tracking, defined by the cell coordinates of the frame memory.

  Next, motion detection processing is performed (S902). The motion detection unit 30 notifies the target tracking unit 31 of motion detection when it exists in the motion detection area.

  Next, the CPU determines whether or not it is immediately after the system is turned on (S903). If it is immediately after the system is turned on, it is determined whether or not there is one moving body (S904). This is to prevent a student who enters the sense area immediately after the system is turned on from tracking and zooming in on the target (referred to as a small target) first. The sense area is a single horizontal character as a simple means for suppressing the movement of the tracking camera in the tilt direction. In other words, the target standing in front of the platform can be zoomed up and tracked.

  Next, in step S904, when the motion detection unit 30 determines that there is only one moving body, a motion detection image (an image adjacent to the previous image) is stored in the target tracking unit 31 from the first frame memory. Cut out and determine whether or not this cut-out image exists in a preset sense area. If the cut-out image exists in the sense area, this target is extracted (S905).

  Next, it is determined whether there is one extracted target (S906). If it is determined that there is one target, the center of gravity of the extracted target is determined, a symbol code (including coordinates) is generated, and the tracking camera control unit 32 Tracking consisting of a zoom-in signal with a predetermined zoom ratio for capturing the target and a pan / tilt angle and speed control signal for capturing the target as the center of the target (teacher: in this embodiment, referred to as a large target) A control signal is output to the tracking camera 20 to zoom in (S907: see FIG. 11).

  When the tracking camera 20 receives a tracking control signal, the internal drive unit controls pan and tilt. At this time, since the top plate 10 and the top plate 11 are provided apart from each other, the pan and tilt vibrations of the tracking camera 20 are not transmitted to the wide-angle camera 21. Therefore, the wide-angle camera image is stable even during tracking.

  Next, when it is determined in step S903 that it is not immediately after the system is turned on, the target tracking unit 31 cuts out the motion detection image, determines whether or not the cut out image exists in a preset sense area, If it exists in the sense area, this target is extracted (S908).

  Next, the target tracking unit 31 determines whether there are two or more targets (S909). If it is determined in step S909 that the number is not two or more, the process returns to step S902, the motion image is detected, and the moving object in the sense area is tracked while zooming in.

  If it is determined in step S909 that there are two or more targets, it is determined whether there are three or two targets (S910).

  If it is determined in step S910 that there are two targets in the sense area (teacher and one student: see FIG. 12), the tracking camera control unit 32 generates and outputs a tracking signal for removing the teacher's large target. (S914a).

  Next, the target tracking unit 31 determines the center of gravity (center) of the extracted small target, generates a symbol code (including coordinates), and the tracking camera control unit 32 sets the center of this target (student: small target) ( 6), a zoom-in signal having a predetermined zoom ratio for capturing a small target and a tracking control signal including a pan, tilt angle, and speed for capturing a small target are output to the tracking camera 20 to zoom in (S914b). ). That is, a signal for zooming in on the tracking camera control unit 32 based on the spread of the area occupied by the target is output.

  At this time, since the top plate 10 and the top plate 11 are provided apart from each other, the pan and tilt vibrations of the tracking camera 20 are not transmitted to the wide-angle camera 21. Therefore, the wide-angle camera image is stable even during tracking.

  If it is determined in step S910 that there are three targets, the large target is zoomed out (S911). Next, the multiple target range tracking setting unit 33 obtains a distance between the small targets, determines a zoom-in range based on this distance, zooms in (S912), and performs a tracking process (S913). In other words, when a student leaves the sense area, tracking is handed over to the teacher's target.

  Therefore, when the target leaves the sense area, it zooms out, but then the same image as when the camera angle is pulled is displayed on the student terminal, which is a natural state. Become. For this reason, auditors at remote locations can acquire natural images without getting sick of cameras.

  Then, when the lecture is started and multiple students approach the teacher and enter the sense area (such as report submission and role playing), the system is multiple (for example, three or more). The image is zoomed out by recognizing and transmitting a zoom-out signal to the tracking camera 2). This zoom-out operation is executed after the imaging area of the tracking camera 20 is returned to the center position. In addition, the zoom-out operation is also effective because it can be zoomed out first and then returned to the center position, returning to the preset center position while copying the target, so that the object will not be missed. .

  Furthermore, since the top plate 10 and the top plate 11 are provided apart from each other, the pan and tilt vibrations of the tracking camera 20 are not transmitted to the wide-angle camera 21. Therefore, the wide-angle camera image is stable even during tracking.

  On the other hand, this system includes casters 2a, 2b, 2c, and 2d. For this reason, it is possible to move to another classroom and deliver the contents of the lecture.

  That is, when the classroom is moved and the inside of the classroom is photographed, it is sent to the server 18 (with a monitor and an operation board) and provided to the external terminal 28 via the Internet 27.

<Embodiment 2>
FIG. 13 is a detailed configuration diagram of the system according to the second embodiment. In FIG. 13, the same components as those in FIG.

  In the system according to the second embodiment, the tracking camera control unit 32 is connected to the tracking camera 20 of the top board 10, the wide-angle camera 21 of the top board 11 is connected to the motion detection unit 30, and the telescopic poles are collected on one of the telescopic poles. The sound microphone 43 is attached. In addition, a television, a video deck, and an image storage device 16 are connected. Furthermore, a pressure sensor 46 is provided on the door or the like. The pressure sensor 46 is activated by washing in the monitoring mode, and can be monitored at night. Therefore, even if there is a room to be monitored at night other than the lecture, it can be moved and used immediately.

  In this apparatus, the wide-angle video of the wide-angle camera 21 is input to the motion detection unit 30a of the motion detection unit 30, and the motion detection unit 30 detects only the image information (cell set) that has changed. Then, it is determined whether or not this detected image exists in the motion detection area of the memory 50b. At this time, the detection is performed by avoiding the mask area of the memory 30c so as not to detect an unrelated part.

  The memory 31b stores a sense color for detecting a specific color and a sense shape for detecting whether there is a specific shape.

  When the clipping unit 31a of the target tracking unit 31 detects a moving image, the clipping unit 31a passes through the sense area, the presence / absence of a moving object, the size, position, moving direction, moving speed, and moving area of the clipped motion detection image. Whether the motion detection image has a specific color or not is stored in the buffer 50.

  In addition, the cutout unit 31 a stores, in the buffer 51, whether or not the specific shape based on the memory 31 b is detected in the buffer 51, the size and type of the specific shape.

  These are connected to the system bus and decoded by the computer 41 (CPU 41) so that control data of the tracking camera 20 can be obtained.

  The analog video signal from the tracking camera 20 is digitally converted by the A / D converter 53 and stored in the image storage device 16 (HDD, MPEG, JPEG compression) by the CPU 41.

  The audio signal from the sound collection microphone 43 is digitally converted by the A / D conversion means 54 and stored in the image storage device 16 by the CPU 41.

  On the other hand, the CPU 41 sequentially reads the data stored in the buffer memories 50 and 51 and stores the data in the buffer 56, and sends tracking control signals for controlling pan, tilt, and zoom ratio based on the position information in the buffer 56. It is generated from the camera state and output to the tracking camera control unit 32.

  The tracking camera control unit 32 reads the camera parameters in the memory 40 and outputs a control signal based on the tracking control signal to the tracking camera 20.

  At this time, since the top plate 10 and the top plate 11 are provided apart from each other, the pan and tilt vibrations of the tracking camera 20 are not transmitted to the wide-angle camera 21. Therefore, the wide-angle camera image is stable even during tracking.

  Further, in the memory 55, information for each classroom (mask range, motion detection area, sense area, specific sense color, etc.) is stored by the operation means, and these classroom information is stored in the motion detection unit 30, The target tracking unit 31 is set.

  Furthermore, the memory 55 stores video gestures and voice gestures so that zoom-in is performed when a specific gesture or voice is generated.

  Then, by calling a menu for switching the camera use mode along with the operation of various devices, it is possible to appropriately change to, for example, the audiovisual education mode, the monitoring mode, and the attendance mode. In this embodiment, the audiovisual education mode is set.

  In addition, as shown in FIG. 14A, the teacher may mark the blackboard using the LED light emitting pen.

  In such a case, the CPU 41 may obtain a red locus from the clipped image, determine the center of this locus as a target, and determine and track a range including the locus in FIGS. 14B and 14C. .

  That is, when the instructor performs an operation on the board to explain with a marker, the zoom-in operation is performed with the marker at the center, and the written one is displayed in a large size. Tracking is suppressed until a new marker is emitted to the board. In addition, since the type of gesture of the lecturer moves the arm up and down, the tracking is large and the tracking is suppressed unless the red marker moves. That is, the motion detection operation is slowed down.

  In addition, the lecturer can operate various video devices and lighting by operating icons displayed on the monitor of the server shown in FIG.

  For example, during a lecture, when a viewer icon is touch-operated in order to project a document on hand with the viewer, the screen is operated and illuminated or dimmed by the operation signal. By this operation, the setting of the mask area M described above becomes effective instead of the tracking function described above. Therefore, each terminal can view a stable image projected on the screen. Similarly, the mask area M functions dominantly during the PDP operation.

  When such video equipment is used, the tracking camera 20 is zoomed out at the camera center position and its movement is suppressed, so that it is possible to provide a natural video for the viewer, which is a preferable usage for the viewing system.

<Embodiment 3>
FIG. 16 is a schematic configuration diagram of an automatic tracking device of the mobile object imaging system according to the third embodiment. The third embodiment includes a multiple target imaging control unit 60 in addition to the configuration of each unit of the first embodiment. The multiple target imaging control unit 60 sets the range Gi for the multiple target range tracking setting unit 33 to obtain, for example, the second target (student) and the third target (student) in addition to the first target (teacher). When such a determination is made (first target (teacher)), a control signal for gradually zooming (or in steps) using the center of the range Gi as the optical axis of the tracking camera is sent to the tracking camera control unit 32 ( The zoom ratio to be pulled is determined by the range Gi).

  In addition, the multiple target imaging control unit 60 monitors the target tracking unit 31 and recognizes the teacher as a student when the teacher and a student cross. That is, the sense area target is increased. Then, a range Gi in which these targets fall is obtained, and the zoom is pulled as described above. The zoom may be pulled by changing the zoom ratio step by step.

  That is, Embodiment 3 can perform the operations shown in FIGS.

In the present embodiment, for example, a case where a plurality (1 to 5 students) of students go up to the platform while tracking a teacher will be described.

  As shown in FIG. 17A, the target tracking unit 31 tracks a teacher when the teacher is on the platform and is present in the motion detection area and the sense area. When the teacher stops, a control signal for zooming in is sent to the tracking camera control unit.

  At this time, as shown in FIG. 17A, when one student enters the motion detection area or the sense area, the teacher's tracking is stopped and the student is recognized as a new target. In other words, the target changes from teacher to student.

  Next, as shown in FIG. 17B, when the second and subsequent students enter the motion detection area and the sense area, the multi-target shooting control unit 60 determines the number of targets. For example, it is determined whether the number is 5 or less.

  When it is determined that the number of students is 5 or less, the above-described range Gi in which all of these students enter is obtained, and a control signal for gradually zooming is obtained with the center of the range Gi as the optical axis of the tracking camera. (The zoom ratio to be pulled is determined by the range Gi).

  In this embodiment, as shown in FIG. 18 (a), when three students enter, as shown in FIG. 18 (b), photographing is performed in a range Gi where three students except the teacher can enter. As shown in FIG. 18C, the zoom is pulled so that all three persons can enter.

  In addition, as shown in FIG. 19A, the teacher and the student may intersect in the sense area. In such a case, the multi-target shooting control 40 recognizes the teacher as a student (FIG. 19B).

  That is, as shown in FIG. 19B, three students are recognized in the sense area, and the zoom is gradually or step by step so that these students enter (FIGS. 19C and 19D).

  Furthermore, when 5 or more students come in (6 or 7 ...), the optical axis of the tracking camera is aligned with the center of the blackboard so that the zoom can be pulled.
