It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the scope of this application.

When a component is referred to as "connected to" another component, it can be directly or indirectly connected to that other component.

Therefore, they should not be construed as limitations on this application. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality" means two or more, unless otherwise explicitly defined.

[0039] To illustrate the technical solutions provided in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0040] In live streaming applications for sporting events and entertainment performances, multiple cameras are often used to film the subject from different angles to better present the reality of the scene. However, because the subject may move during filming, causing its position to change, there are situations where the cameras cannot capture the subject in a timely manner.

[0041] In view of this, embodiments of this application provide a camera equipment control method, apparatus, computer program product, and camera equipment to solve the problem that the existing camera equipment control methods cannot capture the target subject in a timely manner, resulting in poor shooting effects.

[0042] It should be noted that the subject of the method in this application is a camera device, which may include, but is not limited to, any common camera device in the prior art such as a wide-angle camera or a gimbal camera.

[0043] In this embodiment of the application, in order to better capture the subject to be captured, an area including the subject can be set in the shooting screen, and the camera device can be controlled to shoot based on the area. This allows the camera device to capture the subject to be captured more easily and in a more targeted manner, thereby improving the shooting effect.

[0044] For example, as shown in Figure 1, when filming a sports event, the athlete can be the subject of the filming, the area where the athlete is located (1) can be the area to be filmed, and the camera equipment can be controlled to film the area where the athlete is located more specifically to better reflect the situation of the event.

[0045] For ease of description, the subject to be photographed in this application embodiment can be referred to as the target subject, and the area including the target subject can be referred to as the hotspot area.

[0046] In one specific implementation of this application, hotspot areas can be determined based on user settings. For example, a server can establish a communication connection with the camera device to better control and manage its shooting; the user can set the hotspot area of ​​the camera device interactively on the server's management interface. Alternatively, the user can directly set the hotspot area of ​​the camera device interactively on its display interface.

[0047] In another specific implementation of this application, hotspot areas can be determined based on the recognition results of an artificial intelligence model. Specifically, an artificial intelligence model for target recognition can be used to identify the target subject, and the area including the target subject can be determined as a hotspot area. Here, the artificial intelligence model can be any common artificial intelligence model for target recognition in the prior art, and this application does not limit it.

[0048] In another specific implementation of this application, hotspot areas can be determined by combining user settings with the recognition results of an artificial intelligence model. For example, hotspot areas of the camera device can be recommended based on the recognition results of the artificial intelligence model, and the user can confirm or adjust the recommended hotspot areas to determine the final hotspot areas.

[0049] Once the hotspot area is identified, the camera can focus and shoot based on that area; this can improve the shooting effect and the user's viewing experience.

[0050] In one specific implementation of this application, the user sets a hotspot area on the server's management interface to determine the hotspot area in the shooting frame. The server can then generate a region focus command based on the determined hotspot area and send the region focus command to the camera device so that the camera device can focus on and shoot the hotspot area. After receiving the region focus command, the camera device can parse the region focus command to obtain the set hotspot area. Then, the camera device can focus on and shoot based on the hotspot area.

[0051] In another specific implementation of this application, if the user identifies a hotspot area on the display interface of the camera device, the camera device can directly focus and shoot based on the identified hotspot area.

[0052] In this embodiment, various camera devices can be assembled into a camera system. Different camera devices can be positioned at different locations. During filming, each camera device in the system can capture images of the hotspot area. Therefore, the camera system can capture the target subject from different shooting angles, enriching the viewer's viewing experience. The number and specific locations of the camera devices in the system can be customized and contextualized according to actual needs; this embodiment does not limit this.

[0053] Specifically, if one camera device in the camera system can capture the target subject, but another camera device in the camera system is currently unable to accurately capture the target subject, the camera device capable of capturing the target subject (referred to as the first camera device) can be used to guide the other camera devices that are unable to accurately capture the target subject (referred to as the second camera device) to adjust their posture so that the second camera device can successfully capture the target subject. The camera device control method of this application embodiment will be described below from the perspectives of the first camera device and the second camera device respectively.

[0054] Please refer to Figure 2. One embodiment of a camera control method applied to a first camera device in this application can be divided into steps S201 to S204:

[0055] Step S201: Obtain depth information of the target subject.

[0056] In this embodiment of the application, since the first camera device is able to capture the target subject, the first camera device can determine the position of the target subject in the device coordinate system of the first camera device (referred to as the first projected coordinates) based on the depth information of the target subject.

[0057] Specifically, the depth information of the target subject can be the distance of the target subject relative to the first camera device. When the first camera device takes a picture of the target subject, it will focus on the target subject in order to capture the target subject more clearly; at this time, the first camera device can obtain the distance of the target subject relative to the first camera device (i.e., the depth information of the target subject).

[0058] Step S202: Determine the first projected coordinates of the target subject based on the depth information of the target subject.

[0059] When the first camera captures an image of the target subject, it can be assumed that the target subject is projected into the device coordinate system of the first camera. After obtaining the depth information of the target subject, the coordinates of the target subject in the device coordinate system of the first camera (called the first projected coordinates of the target subject) can be determined based on the intrinsic parameters of the first camera and the depth information of the target subject.

[0060] Step S203: Based on the device coordinate relationship and the first projection coordinate, determine the attitude adjustment information of the second camera device.

[0061] After determining the first projected coordinates of the target subject, the position of the target subject in the device coordinate system of the first camera device can be transformed to the device coordinate system of the second camera device according to the relationship between the first projected coordinates and the device coordinates, so as to obtain the coordinates of the target subject in the device coordinate system of the second camera device (called the second projected coordinates of the target subject), as shown in Figure 3; where the device coordinate relationship is the coordinate transformation relationship between the first camera device and the second camera device.

[0062] After determining the second projected coordinates, the posture of the second camera device can be adjusted so that it can successfully capture the target subject. Specifically, the posture adjustment information of the second camera device can be determined based on the device coordinate relationship and the first projected coordinates.

[0063] In this embodiment, before determining the posture adjustment information of the second camera device, the coordinate transformation relationship between the various camera devices in the camera system can be determined. Then, based on the first projected coordinates of the target subject, the posture adjustment information required by the other camera devices to capture the target subject can be determined.

[0064] In one specific implementation of this application, a camera device can be used to photograph a marked object at a known location in the world coordinate system. Then, the marks in the image can be identified, and the position of the marks can be associated with the corresponding position in the world coordinate system to determine the world coordinate information of the camera device. Here, a first camera device and a second camera device can be used to photograph the marked object at a known location in the world coordinate system. Then, the first camera device can identify the marks in its own captured image and associate the position of the marks with the corresponding position in the world coordinate system to determine the world coordinate information of the first camera device (referred to as first coordinate information). Similarly, the second camera device can also identify the marks in its own captured image and associate the position of the marks with the corresponding position in the world coordinate system to determine the world coordinate information of the second camera device (referred to as second coordinate information). When determining the device coordinate relationship, the first coordinate information and the second coordinate information can be obtained, and based on the first coordinate information and the second coordinate information, the relative positional relationship between the first camera device and the second camera device can be determined. Accordingly, the coordinate transformation relationship between the first camera device and the second camera device can be determined. Specifically, the world coordinate information of the camera device can be represented as (x, y, z, pitch, yaw, roll), where x, y, and z are the components of the camera device on the x-axis, y-axis, and z-axis of the world coordinate system, respectively; pitch is the pitch angle of the camera device (i.e., the angle of rotation of the camera device around the x-axis); yaw is the yaw angle of the camera device (i.e., the angle of rotation of the camera device around the y-axis); and roll is the roll angle of the camera device (i.e., the angle of rotation of the camera device around the z-axis).

[0065] In another specific implementation of this application embodiment, each camera device in the camera system can be equipped with a wireless ranging transceiver (e.g., Ultra Wide Band (UWB)) to send or receive wireless signals. Here, any three or more camera devices can be used as reference camera devices (anchor points). Each camera device can send wireless signals to the reference camera devices and receive wireless signals in response from the reference camera devices. The camera device can calculate the distance between itself and the reference camera devices based on the time difference between the wireless signals it sends and the wireless signals it receives. Then, a multilateration algorithm can be used to calculate the relative position information of the camera device in the camera system based on the distance between the camera device and at least three reference camera devices. Based on the relative position information of the first camera device and the second camera device in the camera system, the coordinate transformation relationship between the first camera device and the second camera device can be determined.

[0066] In another specific implementation of this application embodiment, each camera device in the camera system can be equipped with a laser sensor. The camera device can use the laser sensor to send laser pulses to other camera devices. After being reflected by other camera devices, the laser pulses return to the camera device that emitted the laser pulses. Based on the time difference between the emitted laser pulse and the received laser pulse, the distance between the camera device that emitted the laser pulse and the other camera devices can be calculated. Accordingly, the distance between each camera device in the camera system can be determined. Based on the distance between each camera device, the relative position information of each camera device in the camera system can be determined. Based on the relative position information of the first camera device and the second camera device, the coordinate transformation relationship between the first camera device and the second camera device can be determined.

[0067] In another specific implementation of this application embodiment, a camera device set at a higher position can be used to capture images of other camera devices in the camera system to determine the relative positions between the other camera devices and obtain the relative position information of each camera device; based on the relative position information of the first camera device and the second camera device, the coordinate transformation relationship between the first camera device and the second camera device can be determined.

[0068] After determining the device coordinate relationships, the first projected coordinates can be converted into second projected coordinates. Then, the attitude adjustment information of the second camera device can be determined based on the second projected coordinates.

[0069] In one specific implementation of this application embodiment, the difference between the content currently captured by the second camera device and the second projection coordinates can be calculated, thereby determining the posture adjustment information of the second camera device; wherein, the posture adjustment information of the second camera device may include, but is not limited to, the rotation and translation parameters of the second camera device.

[0070] Step S204: Send the attitude adjustment information to the second camera device so that the second camera device can adjust the attitude based on the attitude adjustment information.

[0071] In one specific implementation of this application embodiment, the first camera device and the second camera device can establish a communication connection through a preset communication link. After determining the posture adjustment information of the second camera device, the first camera device can send the posture adjustment information to the second camera device so that the second camera device can adjust its posture based on the posture adjustment information.

[0072] In another specific implementation of this application embodiment, the first camera device and the second camera device can establish a communication connection with the server through a preset communication link. After determining the posture adjustment information of the second camera device, the first camera device can send the posture adjustment information to the server. After receiving the posture adjustment information sent by the first camera device, the server can send the posture adjustment information to the second camera device so that the second camera device can adjust its posture based on the posture adjustment information.

[0073] The aforementioned communication link can be a communication link established based on at least one wireless communication solution, such as Wireless Local Area Networks (WLAN) (e.g., Wireless Fidelity (WiFi)), Bluetooth, Bluetooth Low Energy, Global Navigation Satellite System (GNSS), Frequency Modulation (FM), Near Field Communication (NFC), Infrared (IR), Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), and Long Term Evolution (LTE).

[0074] In addition, after the posture adjustment information of the second camera device is sent to the second camera device, the first camera device can update the device coordinate relationship and obtain the updated device coordinate relationship.

[0075] The camera device control method of this application embodiment will now be described from the perspective of the second camera device.

[0076] Please refer to Figure 4. One embodiment of a camera control method applied to a second camera device in this application may include steps S401 to S402:

[0077] Step S401: Receive attitude adjustment information.

[0078] In this embodiment of the application, the second camera device can receive the posture adjustment information of the second camera device determined by the first camera device.

[0079] In one specific implementation of this application embodiment, the second camera device can establish a communication connection with the first camera device. The first camera device can send the posture adjustment information of the second camera device to the second camera device through the communication connection, and the second camera device can receive the posture adjustment information sent by the first camera device through the communication connection.

[0080] In another specific implementation of this application embodiment, the first camera device and the second camera device can establish communication connections with the server respectively. The first camera device can send attitude adjustment information to the server. After receiving the attitude adjustment information sent by the first camera device, the server can send the attitude adjustment information to the second camera device.

[0081] Step S402: Based on the posture adjustment information, control the second camera device to perform posture adjustment.

[0082] In this embodiment of the application, after receiving the posture adjustment information, the second camera device can adjust its own posture accordingly in order to capture the target subject more accurately.

[0083] Specifically, the second camera device can analyze the posture adjustment information to determine the rotation and translation parameters of the second camera device, and can make physical adjustments to the second camera device based on the analyzed rotation and translation parameters so that the target subject is located in the field of view of the second camera device.

[0084] In addition, after the second camera device adjusts its posture based on the posture adjustment information, the coordinate transformation relationship between the first camera device and the second camera device changes. Therefore, the device coordinate relationship can be updated based on the posture adjustment information to obtain the updated device coordinate relationship.

[0085] Furthermore, to avoid monotonous playback and a single shooting perspective, during actual shooting, the playback can be switched between different camera devices based on preset switching rules. Specifically, the switching rules can be customized and contextualized according to actual needs, and this application embodiment does not limit this.

[0086] In one specific implementation of this application, the switching rule can be to switch the playback screen to the camera device whose hotspot area is located in the center of the shooting screen. For example, if the hotspot area of ​​camera device A is located in the center of camera device A, then the screen of camera device A can be used as the playback screen; subsequently, the target subject moves beyond the shooting screen of camera device A and enters the shooting screen of camera device B and is located in the center of camera device B (i.e., the hotspot area of ​​camera device B is located in the center of camera device B); therefore, the playback screen can be switched to the screen of camera device B.

[0087] In another specific implementation of this application, the switching rule can be to switch the playback screen from the output of the current camera device to the output of another camera device at specific time intervals. Here, the specific value of the specific time interval can be customized and contextualized according to actual needs, and this application does not limit it. For example, the specific time interval can be 15 seconds, that is, the playback screen is switched from the output of one camera device to the output of another camera device every 15 seconds.

[0088] Switching between different playback screens can enrich the playback content and help improve the viewer's viewing experience.

[0089] In summary, this application embodiment obtains the depth information of the target subject; based on the depth information of the target subject, determines the first projected coordinates of the target subject; wherein the first projected coordinates are the coordinates of the target subject in the device coordinate system of the first camera device; based on the device coordinate relationship and the first projected coordinates, determines the posture adjustment information of the second camera device; wherein the device coordinate relationship is the coordinate transformation relationship between the first camera device and the second camera device; and sends the posture adjustment information to the second camera device so that the second camera device can perform posture adjustment based on the posture adjustment information. In this application embodiment, when the first camera device captures the target subject, it can guide the second camera device to perform posture adjustment based on the device coordinate relationship, thereby enabling the second camera device to capture the target subject in a timely manner, which helps to improve the shooting effect.
