In this proposal, multi-camera images are converted into perspective projected images, and the positional relationship and size of the two images are adjusted. Then, we proposed a method of generating a wide-area synthetic image by correcting the deviation due to the difference in the viewpoint position of the wide-field camera and the multi-camera using a known pattern matching method, deforming the multi-camera image, and matching it. there is

However, in the above-described conventional example, since the colors and sizes of multiple images to be synthesized and the misalignment (distortion) of the field of view are only matched, there is no mention of the cameras and lenses used, and the following problems arise. there were.

When shooting a wide range of shooting areas with a plurality of camera devices and generating a composite image, many cameras may be required depending on the cameras and lenses that can be used. In such a case, cameras and lenses with the same performance may be used, but camera devices with different resolutions and optical performances may be installed together because the sensors and lenses of the cameras are different.

Currently, when synthesizing images shot with multiple cameras with different characteristics under such shooting conditions, we use the methods shown in conventional examples and monitor images to match the colors, angle of view, and focus. Visual adjustment is possible.

However, considering many other factors such as resolution (resolution and MTF), aberration, etc., it is difficult to synthesize images by aligning even the apparent image quality between multiple cameras, and it is not shown. As a result, there arises a problem that the difference in image quality occurs among the plurality of cameras, and the synthesized boundary is recognized by the viewer.

In general, in a wide ground or stadium, when using multiple imaging devices to shoot the whole image, prepare a high stand or a high pole or tower as shown in Figures 5 and 6, and then It is common to be installed in a form overlooking the ground from.

In the imaging device 100 (here, the camera A301) to be installed, when the process starts in processing step S500, the process proceeds to processing step S501, and the image quality setting unit 103 sets the required image quality when generating a composite image. Select conditions. The image quality condition represents the level of the image quality satisfaction range in consideration of many other factors such as resolution (resolution and MTF), aberration, etc. in the range of the image taken. , 3K, and 4K may be selected, or a resolvable object size may be used.

After selecting the image quality condition by the image quality setting means 103, the process proceeds to processing step S502, and the shooting parameters (depth of field, angle of view, sensor resolution, MTF, etc.) is displayed and presented on the UI multiple display means 110 provided in the imaging apparatus 100 .

Then, proceeding to processing step S503, the photographer confirms whether or not to add or delete shooting parameters from the shooting parameters presented in processing step S502. In the case of addition/deletion, the process proceeds to processing step S504, and addition/deletion of imaging parameters is performed by the imaging parameter selection unit 104. FIG.

Typical imaging parameters are listed below. Other elements may be added as imaging parameters, not limited to these.

・Focus position ・Depth of field ・Angle of view ・Sensor resolution (resolution)
・Resolution change by aperture value ・S/N ratio ・MTF
• Aberration • Brightness • Color temperature The process advances to step S505 to acquire the selected shooting parameters.

Then, the process proceeds to processing step S506, and the device information acquisition unit 102 acquires information necessary for area calculation with the selected imaging parameters. Apparatus information acquiring means 102 acquires camera information from an image sensor 107 mounted on the imaging apparatus 100, and lens information acquired from the imaging optical system 200 via lens information transmitting means 201 from lens information acquiring means 101. get. Then, the installation position information of the imaging device 100 is acquired from the image synthesizing device 300 connected to the imaging device 100 .

The camera information, lens information, and installation position information to be acquired are as follows.
Camera information: Image sensor size (horizontal, vertical), sensor pixel pitch, number of sensor pixels, permissible circle of confusion Lens information: F value, focal length, subject distance (focusing distance)
Installation position information: installation height, installation coordinates from the reference point, installation angle,

The installation position information includes installation coordinates from a reference point. This information is acquired and stored by the image synthesizer 300 for the installation position information of a plurality of cameras to be installed. It is used when requesting acquisition of installation position information from the imaging device or information acquisition of adjacent cameras.

Also, the installation coordinates are such that a reference Or (0, 0) as shown in FIG. do.

As an example, the method of calculating the installation coordinates in the form of FIG. 7 is shown, but the reference point may be any position, and any method may be used as long as the installation positions of the plurality of imaging devices to be installed can be determined. Don't ask.

Table 1 shows part of the information necessary for area calculation in the above imaging parameters.

処理ステップＳ５０７に進み、取得したカメラ情報、レンズ情報、設置位置情報から、選択した各撮影パラメータの領域を撮影領域算出手段１０５にて算出する。本実施例では、一例として、処理ステップＳ５０５にて取得した撮影パラメータが、画角、被写界深度、分解能（解像度）、ＭＴＦとして、説明する。

Proceeding to processing step S507, the shooting area calculation unit 105 calculates the area of each selected shooting parameter from the acquired camera information, lens information, and installation position information. In this embodiment, as an example, the shooting parameters acquired in processing step S505 are the angle of view, the depth of field, the resolution (resolution), and the MTF.

When calculating the area, in processing step S501, from the selected image quality conditions, criteria are provided for judging whether each shooting parameter of angle of view, depth of field, resolution (resolution), and MTF is OK/NG. The area determined as OK based on the above is the area to be obtained.

A region that satisfies the selected image quality is calculated individually for each of the acquired imaging parameters, the angle of view, the depth of field, the resolution, and the MTF.

First, the area in the angle of view is calculated using the acquired information sensor size, subject distance, focal length, and installation height. The calculation area of the angle of view is the dotted line area as shown in FIG. Basically, it is the entire shooting area, but it is calculated in order to define the usable area as the image.

Next, the area in the depth of field is calculated using the obtained information F value, subject distance, focal length, installation height, and permissible circle of confusion. The calculation area of the depth of field is the dotted line range as shown in FIG. It represents the range in which a predetermined image quality can be maintained without readjustment of the focus even if the complemented subject placed at the best focus position moves back and forth with respect to the lens position.

Next, the area in resolution (resolution) is calculated using the acquired information sensor size, subject distance, focal length, installation height, and number of sensor pixels. A resolution (resolution) calculation area is a dotted line range as shown in FIG. 10 . The resolution is "how many millimeters of the subject one pixel of the sensor corresponds to".From the selected image quality conditions, the size required to distinguish the details of the subject is obtained, and the range of subject distance that satisfies that condition is determined. It represents

Next, the area in the MTF is calculated using the acquired information F value, focal length and image height from the optical axis center. The calculation area of the MTF is the dotted line range as shown in FIG. MTF indicates the imaging performance of a lens and indicates how faithfully the contrast of an object can be reproduced as an image.The contrast and resolution of the lens that satisfy the selected image quality at the distance from the image center. represents the range of After the calculation of the area of the angle of view, depth of field, resolution (resolution), and MTF, which are the acquired imaging parameters, is completed, the process proceeds to processing step S508, where the calculated areas of the imaging parameters are superimposed, and all the elements Calculate the region that satisfies

As shown in FIG. 12, by superimposing the calculated areas (ranges) in the calculation of the angle of view, depth of field, resolution, and МTF, all the shooting parameters satisfy the selected image quality. can ask. In this embodiment, this calculated area is called a common area.

When the processing of processing step S508 ends, the processing of the area calculation subroutine ends, and the process proceeds to processing step S403.

In processing step 403, the calculation area of each imaging parameter calculated by the area calculation subroutine is saved. Then, the process proceeds to processing step S404, and stores the common region calculated by superimposing the calculation regions of all the imaging parameters calculated in processing step S508.

Next, the process proceeds to processing step S405. In processing step 405 , it is confirmed whether the calculated common area is to be displayed on the UI multiple display means 110 that is the display means provided in the imaging apparatus 100 . In the UI multiplex display means 110 provided in the imaging device 100, the light imaged on the image sensor 107 through the imaging optical system 200 is converted into a video signal and displayed as a captured video via the video output means 109.

If the calculated common area is to be displayed on the UI multiple display means 110, the process proceeds to processing step 406, and the area pattern generation means 106 displays the UI multiplex based on the common area calculated by the imaging area calculation means 105. A display pattern that can be displayed by means 110 is generated.

Proceeding to processing step S407, based on the generated display pattern, as shown in FIG. The position where the common area is displayed is calculated and displayed from the installation position of the imaging device 100 acquired from the video synthesizer 300 and the calculated position of the common area in the display range of the captured video. That is, the position information of the calculated common area is converted to the coordinate information C(x , y) to determine the absolute position from the reference point Or. Then, the range occupied by the common area is defined as coordinate data from P1 (Xa1, Y1) to Pzz (Xbzz, Yzz) as shown in FIG. 15 from the pixel information in the captured image.

Proceeding to the next processing step S408, the display pattern of the displayed common area is confirmed, and the installation position of the camera A301 is determined. In this embodiment, an example of the installation method will be shown, and the invention will be explained. The installation method is arbitrary, and is not limited to this method.

First, it is confirmed which part of the field the common area displayed on the UI multiple display means 110 of FIG. 13 covers. For example, in order to capture the entire field court with multiple cameras without any gaps, it is necessary to install the cameras in order from the corner, which is the edge of the court. Therefore, while looking at the displayed area, the installation position of the camera A301 is changed so that the common area covers the corner as shown in FIG. When the installation position is changed, the common area is calculated again according to the situation (processing step S409).

When the installation position of the camera A301 is determined, the process proceeds to processing step S410, and as shown in FIG. It is confirmed whether the UI multiplex display means 110 is to display.

Currently, the UI multiple display means 110 of the imaging apparatus 100, which is the camera A301, displays a common area that satisfies the image quality selected by the camera A301. It is necessary to determine the installation positions of the cameras B302 and C303. Therefore, if the camera installation is to be continued in processing step S410, the process proceeds to processing step S411, and if not, the processing proceeds to processing step S420.

In processing step S411, as shown in FIGS. 1 and 2, in order to have the video synthesizing device 300 connected to the camera A301, which is the imaging device 100, calculate a common area with adjacent cameras, The information of the specified camera for which the area calculation is requested is transmitted via the photographing information input/output means 112 . Here, the designated cameras are camera B302 and camera C303.

Proceeding to processing step S412, the specified photographing parameters necessary for calculating the common area are transmitted to the video synthesizing apparatus 300. FIG. These shooting parameters are the shooting parameters selected and obtained when the camera A301 calculates the area, and are the same as the shooting parameters used when the camera A301 calculates the common area.

Proceeding to processing step S413, the image synthesizing device 300 requests the camera specified in processing step S411 to calculate an area using the shooting parameters acquired in processing step S412. Assuming that the imaging device requested is the camera B302, for example, the camera B302 receives the designated imaging parameters from the video synthesizing device 300. FIG. These shooting parameters are the same angle of view, depth of field, resolving power (resolution), and MTF as the shooting parameters used for area calculation in the camera A301. The camera B302 that has received the shooting parameters performs the same processing as the area calculation subroutine in processing step S402 to calculate a common area for the camera B302.

Then, in processing step S414, the image synthesizing device 300 acquires the area information calculated by the designated camera. Here, information on the calculated common area is acquired from the camera B302. The information acquired here is the position information of the common area described in the processing step S407.

When the image synthesizer 300 completes acquiring the position information of the common area of the designated camera, the process advances to step S415, and the image synthesizer 300 sends the area information calculated by the acquired designated camera to the imaging apparatus that has received the request. Send. Here, the position information of the common area calculated by the camera B302 is transmitted to the camera A301.

Proceeding to processing step S416, the imaging device 100 that has received the positional information of the common area generates a display pattern that can be displayed on the UI multiple display means 110 based on the information.

Then, the process proceeds to processing step S417, and the display pattern is displayed on the UI multiple display means 110 of the imaging device 100 based on the display pattern. That is, as shown in FIG. 18, the common area calculated by the camera B302 is converted into a display pattern that can be superimposed and displayed on the display device of the camera A301. It will be.

Next, proceeding to processing step S418, it is confirmed whether or not to additionally display the calculation area of another adjacent camera. In addition, if it is desired to superimpose and display the common area calculated by the adjacent imaging devices on the UI multiplex display means 110, the processing returns to step S411, the camera is specified again, and the image synthesizing device 300 is requested to calculate the area. .

If there is no need for additional display, the process proceeds to processing step S419. Here, since the position information of the common area calculated by the adjacent camera C303 is required, the process returns to the processing step S411, the same processing as the camera B302 described above is performed, and the position information of the common area calculated by the camera C303 is is obtained from the video synthesizer 300 . A display pattern is generated based on the acquired information, and the display pattern is superimposed and displayed on the UI multiple display means 110 of the camera A301 as shown in FIG.

Since it is assumed that the two adjacent cameras are camera B302 and camera C303, the process advances from processing step S418 to processing step S419. In processing step S419, while confirming the area displays of camera A301, camera B302, and camera C303 displayed on the UI multiplex display means 110, the installation positions of camera B302 and camera C303, which are respective imaging devices, are determined.

As shown in FIG. 20, while checking the position of the common area of cameras B 302 and C 303 based on camera A 301 whose installation position has been determined, the installation positions are changed so that the common area of each camera can cover the field without gaps. to decide. When the installation positions of camera B302 and camera C303 are changed, the common area is calculated again according to the situation.

After the installation position of each camera is determined, the process proceeds to processing step S420, and it is confirmed whether or not the area display on the UI multiple display means 110, which is the display means, is finished. When displaying as it is, the process returns to the processing step S409. When the area display is finished, the process proceeds to processing step S421, and the area display on the UI multiple display means 110, which is the display means, is finished.

In the description of the first embodiment, the camera A301, the camera B302, and the camera C303 have been picked up and described, but a method of installing adjacent cameras based on the calculated common area has been described.

However, in order to shoot a large ground or stadium with more cameras and generate a composite image with a selected image quality or higher, the entire field is taken as a single image. , the installation position must be determined in a similar way. In that case, the processing steps S411 to S417 are repeated, the common area of each camera is confirmed on the UI multiple display means 110 which is a display device, and the common area calculated by each camera is used for the ground or stadium. Cover the whole without any gaps. After the entire coverage is completed, the video synthesizing device 300 selects the video range to be synthesized from the video acquired from each camera based on the installation position information of each camera and the position information of the common area calculated by each camera. It is possible to cut out and generate a composite video.
