Description

Technical Field

[0001] This application relates to the field of audio and video, and more specifically, to a video acquisition method, apparatus, and electronic device. Background Technology

[0002] In the current field of visual media, the camera is the core of the entire visual acquisition process, and its real-time setup and adjustment capabilities directly affect the output quality of media content. However, current camera adjustment methods primarily rely on manual adjustments by operators, which is not only time-consuming and labor-intensive, but also inefficient. Furthermore, adjustments to camera parameters often exhibit lag, preventing the camera settings from keeping pace with real-time changes in the target object. This results in visual content failing to accurately convey the target object's intent, thus impacting video quality. Additionally, when adjusting the camera direction using vision-following video acquisition methods, the adjustment is mainly based on the gaze signals received by sensors. However, these methods do not comprehensively consider all factors, preventing the camera from achieving real-time tracking and resulting in poor video capture quality.

[0027] First, some nouns or terms that appear in the description of the embodiments of this application shall be interpreted as follows:

[0028] A sensor is a device or apparatus that can detect and sense a specified measurand and convert it into a usable signal (usually an electrical signal) according to a certain rule. It can convert non-electrical quantities (such as temperature, pressure, light intensity, and speed) into electrical quantities (such as voltage, current, and resistance) to facilitate subsequent signal processing and analysis. Sensors are widely used in industrial automation, environmental monitoring, medical equipment, and consumer electronics.

[0029] Azimuth angle is the angle of rotation of a line of sight on a horizontal plane, usually relative to the front, and is the angle of rotation to the left or right.

[0030] The elevation angle describes the vertical rotation of the line of sight in the vertical plane, that is, the angle between the line of sight and the horizontal plane. When looking upwards, the elevation angle is positive; when looking downwards, the elevation angle is negative. In a three-dimensional coordinate system, the elevation angle can be expressed as the angle between the line segment from the line of sight to the horizontal plane and the line segment from the line of sight to the positive z-axis.

[0034] The method embodiment provided in Embodiment 1 of this application can be executed on a mobile terminal, computer terminal, or similar computing device. Figure 1 A hardware block diagram of a computer terminal (or mobile device) for implementing a video acquisition method is shown. Figure 1 As shown, the computer terminal 10 (or mobile device) may include one or more processors 102 (shown as 102a, 102b, ..., 102n in the figure) 102 (processor 102 may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.), a memory 104 for storing data, and a transmission device 106 for communication functions.

For example, computer terminal 10 may also include... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0035] It should be noted that the aforementioned one or more processors 102 and / or other data processing circuits are generally referred to herein as "data processing circuits". These data processing circuits may be embodied, in whole or in part, in software, hardware, firmware, or any other combination thereof. Furthermore, the data processing circuits may be a single, independent processing module, or may be integrated, in whole or in part, into any other element within the computer terminal 10 (or mobile device). As involved in the embodiments of this application, the data processing circuits serve as a processor control mechanism (e.g., selection of a variable resistor termination path connected to an interface).

[0036] The memory 104 can be used to store software programs and modules of application software, such as the program instructions / data storage device corresponding to the video acquisition method in this embodiment. The processor 102 executes various functional applications and data processing by running the software programs and modules stored in the memory 104, thereby realizing the above-mentioned video acquisition method.

[0038] The display can be, for example, a touchscreen liquid crystal display (LCD) that allows the user to interact with the user interface of the computer terminal 10 (or mobile device).

[0039] Under the above operating environment, this application provides an optional video acquisition method. Figure 2 This is a flowchart of a video acquisition method according to an embodiment of this application, such as... Figure 2 As shown, the method includes the following steps:

[0040] Step S202: During the video capture process using the camera, detect whether the target object is within the camera's shooting range;

[0041] Optionally, a camera can continuously monitor target objects in the scene to detect whether they are within the camera's field of view. This is fundamental for all subsequent tracking, gaze detection, and direction control. The detection result directly determines whether subsequent steps are executed. For example, if the target object is within the camera's field of view, the camera will begin acquiring the target object's gaze direction; if the target object is outside the field of view, a specific process will be triggered. Continuous detection allows for timely responses to target object movements, ensuring rapid adaptation to changes in target position, which is crucial for maintaining the continuity and quality of video recording. Accurately detecting whether the target object is within the camera's field of view ensures the accuracy of video acquisition, thereby preventing the loss of critical information due to the target being out of sight. Furthermore, real-time detection capabilities ensure that the camera can track the target object in real time. Even if the target object briefly leaves the camera's field of view, the camera can quickly adjust to recapture the target, maintaining the continuity of video recording. In addition, accurate detection and rapid response to target objects can reduce the unpleasant experience of users "losing" targets when watching videos, improving the overall viewing experience and user satisfaction. Avoiding unnecessary camera orientation adjustments helps optimize the resource utilization of the video acquisition system, such as reducing unnecessary driver movements, lowering energy consumption, and reducing camera wear.

[0042] Step S204: When the target object is within the shooting range, obtain the direction of the target object's gaze;

[0043] Optionally, when the target object is within the camera's field of view, the target object's gaze direction can be acquired. This can be achieved, but is not limited to, acquiring the target object's gaze direction through computer vision techniques and algorithms (such as face recognition and eye tracking) to identify the target object's eyes and determine its gaze direction, which includes, but is not limited to, the direction and focus of the gaze.

[0044] Optionally, the acquired gaze direction information is crucial for generating control signals. Without accurate gaze direction, subsequent camera orientation adjustments will lose their target, resulting in poor video capture quality. Real-time detection and gaze direction acquisition also ensure that the camera system can respond instantly to changes in the target object's gaze, which is especially important for vision-tracking-based video capture, maintaining consistency between the video content and the target object's gaze.

[0045] In an optional embodiment, the method further includes: acquiring the gaze signal of the target object through a sensor device when the target object is not within the shooting range; and adjusting the direction of the camera based on the gaze signal so that the target object is within the shooting range.

[0046] Optionally, adjusting the camera direction when the target object is not within the shooting range ensures normal shooting of the target object. When the target object temporarily leaves the camera's shooting range, this embodiment uses sensor devices to collect the target object's gaze signal, enabling the detection and relocation of the missing target, ensuring the continuity and integrity of video acquisition. Furthermore, when faced with uncertainty in the target's position, this embodiment can self-correct using additional sensor information, avoiding interruptions or loss during video acquisition. This ensures that even when the target object is not in the field of view, the camera direction can be automatically detected and adjusted, reducing the need for manual intervention and making video acquisition more automated.

[0047] Step S206: Based on the line of sight, generate a control signal, wherein the control signal is used to indicate at least: the direction that the camera needs to be adjusted, and the adjustment range of the direction, the direction including azimuth angle and / or pitch angle;

[0048] Optionally, after obtaining the target object's gaze direction, a control signal can be generated based on that gaze direction. The control signal is an instruction for the camera to adjust its direction, including but not limited to the direction and magnitude of adjustment required, ensuring the camera accurately points to the target object's gaze focus. Even when the target object's gaze changes rapidly, the camera's direction can be quickly adjusted to capture the target object's focus, thereby improving the accuracy and quality of video acquisition. By analyzing the target object's gaze direction, the camera's azimuth and / or pitch angle adjustment needs are intelligently determined. The generated control signal includes parameters for direction and adjustment magnitude. This process requires precise settings to ensure rapid and accurate camera adjustment while avoiding image instability caused by over-adjustment. Through fine-grained control, the camera can maintain the optimal shooting angle, avoiding video quality problems caused by incorrect angles, such as blurred targets and scene edge distortion, enhancing the video's visual appeal and usability. Automated control reduces the need for manual adjustments by the operator, maintaining automatic camera tracking even in complex shooting environments, simplifying the operation process and improving video acquisition efficiency.

[0049] Optionally, control signals can be generated to automatically adjust the camera's direction and focal length based on the target object's line of sight and a pre-defined visual range. The camera receives the control signals through a driver and adjusts them accordingly, enabling the camera to follow the target object's line of sight in real time.

[0050] In one alternative embodiment, generating a control signal based on the line-of-sight direction includes: detecting whether the camera is within a preset visual range of the target object; and generating the control signal based on the line-of-sight direction if the camera is within the preset visual range.

[0051] Optionally, before generating the control signal, it can be detected whether the camera is within the preset visual range of the target object, serving as a pre-screening step for target object gaze tracking and camera adjustment. Setting the preset visual range helps limit the camera's adjustment range, avoiding frequent malfunctions when camera adjustments are unnecessary, while ensuring more reasonable and efficient camera adjustments. Limiting the camera's adjustment range optimizes resource utilization and avoids excessive power consumption and unnecessary wear on the driver, improving the overall efficiency and economy of video shooting. When the camera is detected to be within the preset visual range of the target object, generating a precise control signal based on the target object's gaze direction demonstrates accurate capture of the target object's gaze focus and ensures that the camera can intelligently adjust to optimally follow the target's gaze.

[0052] Optionally, the preset visual range can be flexibly adjusted according to specific application scenarios. This embodiment can adapt to both indoor environments and vast outdoor spaces. For example, the preset visual range can be set to the target object's line of sight within a 120-degree radius. This ensures that the camera effectively tracks within a reasonable range, enhancing the adaptability and flexibility of the video acquisition system.

[0053] In one optional embodiment, generating a control signal based on the gaze direction includes: detecting whether the gaze direction of the target object has changed; if a change in gaze direction is detected, obtaining the magnitude of the gaze change of the target object; if the magnitude of the gaze change is greater than a preset magnitude, generating a control signal based on the changed gaze direction.

[0054] Optionally, in this embodiment, by continuously detecting changes in the target object's gaze direction, the camera can quickly respond to dynamic changes in the target object's gaze, improving the camera's intelligent adaptive capability in following the target's gaze. When the gaze change is significant, control signals are generated and the camera direction is adjusted, thereby reducing the frequency of camera adjustments and avoiding unnecessary changes. By generating a control signal based on the new gaze direction when the target object's gaze changes and the change exceeds a preset value, it can be ensured that the control signal is generated based on the most effective gaze information at present, avoiding unnecessary camera adjustments. Setting a preset amplitude also provides a decision benchmark; a new control signal is only generated when the gaze change exceeds this threshold, which helps reduce frequent camera adjustments and avoids image jitter or instability during video acquisition.

[0055] Optionally, the preset visual range can be a 120-degree visual range around the target object. If the target object is within the visual range, a control signal is generated to adjust the camera's direction and focus; otherwise, no camera adjustment is made. By setting the visual range, the camera's adjustment range can be limited, avoiding frequent malfunctions when camera adjustments are not necessary.

[0056] In an optional embodiment, when the direction includes an azimuth angle, a control signal is generated based on the line-of-sight direction, including: determining the target azimuth angle of the target object's line-of-sight direction in the horizontal direction and the target pitch angle of the target object's line-of-sight direction in the vertical direction; determining the azimuth angle difference between the target azimuth angle and the camera's azimuth angle, and the pitch angle difference between the target pitch angle and the camera's pitch angle; determining azimuth angle adjustment information for the camera based on the azimuth angle difference, wherein the azimuth angle adjustment information includes the azimuth angle adjustment direction and the azimuth angle adjustment magnitude; determining pitch angle adjustment information for the camera based on the pitch angle difference, wherein the pitch angle adjustment information includes the pitch angle adjustment direction and the pitch angle adjustment magnitude; and generating a control signal based on the azimuth angle adjustment information and / or the pitch angle adjustment information.

[0057] Optionally, the horizontal angle difference between the target object's line of sight and the horizontal reference direction, i.e., the target azimuth angle, can be calculated based on the line-of-sight estimation results. The vertical angle difference between the target object's line of sight and the vertical reference direction, i.e., the target pitch angle, can also be calculated based on the line-of-sight estimation results. By determining the horizontal (azimuth angle) and vertical (pitch angle) changes in the target object's line of sight, this embodiment can accurately calculate the azimuth and pitch angles that the camera needs to adjust, thus more accurately following the target object's line of sight. Specifically, changes in the horizontal viewing angle can be directly converted into a horizontal angle adjustment signal for the camera pan / tilt unit or rotation mechanism, thereby adjusting the camera's azimuth angle. Changes in the vertical viewing angle can be converted into a vertical angle adjustment signal for the camera pan / tilt unit or rotation mechanism, thereby adjusting the camera's pitch angle. If the target object's line of sight is downward and the pitch angle with the camera exceeds a certain angle, it is considered that the pitch angle needs to be increased by a predetermined angle; if the target object's line of sight is upward and exceeds a certain angle, it is considered that the pitch angle needs to be decreased by a predetermined angle. The vertical angle difference between the target object's line of sight and the vertical reference direction, i.e., the target azimuth angle, is calculated based on the line-of-sight estimation results. By determining the azimuth and pitch differences, quantitative data can be provided for camera adjustments. This allows the system to determine the adjustment direction and magnitude based on the actual differences, thus enabling more precise video acquisition control. Based on the calculated azimuth and pitch adjustment information, specific control signals are generated to directly guide camera orientation adjustments. For example, changes in the horizontal viewing angle can be directly converted into a horizontal angle adjustment signal for the camera's pan / tilt or rotation mechanism, thereby adjusting the camera's azimuth and ensuring that the adjustment action matches changes in the target object's line of sight.

[0058] In one optional embodiment, generating a control signal based on azimuth adjustment information and / or pitch adjustment information includes: generating a control signal based on azimuth adjustment information when the azimuth difference is greater than a preset first difference threshold and the pitch difference is less than or equal to a preset second difference threshold; or generating a control signal based on pitch adjustment information when the azimuth difference is less than or equal to the preset first difference threshold and the pitch difference is greater than the preset second difference threshold; or generating a control signal based on both azimuth adjustment information and pitch adjustment information when the azimuth difference is greater than the preset first difference threshold and the pitch difference is greater than the preset second difference threshold.

[0059] Optionally, by setting a threshold for the difference between the azimuth and pitch angles, this embodiment can achieve precise control over the camera adjustment, avoid over-responding to minor changes, thereby optimizing the use of driver resources, reducing unnecessary energy consumption and wear, and enhancing the stability and responsiveness of the camera during target object visual tracking. Especially in scenarios where the target's line of sight changes rapidly, this embodiment can make adjustments more quickly and accurately.

[0060] Optionally, the process of adjusting the pitch angle can be achieved as follows: by detecting, identifying, and locating the target object, estimating the line of sight based on the position of the feature points, comparing the horizontal direction of the line of sight with the current azimuth angle of the camera, and calculating the azimuth angle; updating the line of sight direction estimation and azimuth angle adjustment in real time and providing feedback during the adjustment process; and correcting the parameters.

[0061] By adjusting the camera's horizontal direction individually when the target's line of sight changes significantly (azimuth), or adjusting the vertical direction when the vertical direction changes significantly (pitch), or adjusting both directions simultaneously when both changes are significant, the camera's orientation can be flexibly adjusted based on changes in the target's line of sight. Furthermore, adjusting the camera's azimuth or pitch angle accordingly when the difference in azimuth or pitch angle is large can avoid unnecessary adjustments and reduce adjustment frequency. Precisely controlling the separate adjustments of the camera's azimuth and pitch angles ensures that the camera accurately follows the target's line of sight, reducing video content deviation or instability caused by improper camera adjustments, thereby improving video acquisition quality and viewing experience.

[0062] Optionally, in complex environments with varying degrees of change in the target's line of sight, the priority of adjustments can be determined. For example, in scenarios where both camera azimuth and pitch angles need to be adjusted simultaneously, the magnitude of the azimuth and pitch angle differences can be used to determine whether to adjust the camera's azimuth or pitch angle first. For instance, if the azimuth angle difference is greater than the pitch angle difference, it indicates a larger azimuth deviation, and the camera's azimuth angle can be adjusted first; if the azimuth angle difference is less than the pitch angle difference, it indicates a larger pitch deviation, and the camera's pitch angle can be adjusted first. Through these methods, high-quality and continuous video capture can be maintained regardless of rapid horizontal movement or significant vertical changes.

[0063] In one optional embodiment, a control signal is generated based on the line-of-sight direction, including: acquiring distance information between the target object and the camera; and generating the control signal based on the distance information and the line-of-sight direction, wherein the control signal further indicates the focal length that the camera needs to adjust, and the adjustment range of the focal length.

[0064] Optionally, focal length adjustment is primarily used to change the camera's field of view and focusing distance, enabling clear capture of details of the target object's gaze or maintaining the target object's appropriate size in the frame. By simultaneously processing the target object's gaze direction and distance information, camera adjustment not only includes direction but also adjusts the focal length based on the target's distance, achieving more precise video capture. By calculating the distance between the target object and the camera, the adjustment range of the camera's focal length can be automatically determined, ensuring optimal focusing regardless of the target object's distance. In addition to direction adjustment, focal length adjustment also helps optimize the clarity of video capture, especially when the target object is moving rapidly or the camera's position changes significantly, maintaining image stability and clarity. In summary, automatically adjusting the focal length based on changes in the distance between the target object and the camera, and simultaneously adjusting the camera's direction and focal length, can generate control signals for simultaneous adjustment of both camera direction and focal length. This allows for focal length adjustment while capturing the area the target object is looking at, thereby maintaining optimal image quality.

[0065] Step S208: Adjust the camera's orientation according to the control signal so that the camera can capture video along the line of sight.

[0066] Optionally, the camera can receive generated control signals containing information about the direction and magnitude of camera adjustment. These abstract instructions are translated into concrete operations, adjusting the camera's azimuth and / or pitch angles by driving the camera's steering mechanism, ensuring the camera accurately aligns with the target object's line of sight. The dynamic adjustment function is a real-time response to changes in the target object's line of sight, ensuring the camera continuously adjusts its direction to capture the target object's visual focus. Even with minor or rapid changes in the target object's line of sight, the camera adjusts promptly to stay on track. Precise direction adjustment effectively avoids problems such as image jitter and target loss caused by untimely or inaccurate camera direction adjustment during video capture, ensuring continuous and high-quality video acquisition.

[0067] Optionally, when the camera angle changes, real-time gaze feedback can be provided to the operator via a small display screen or headphones. This feedback can include information such as the camera's angle, position, and current status, allowing the operator to understand and make necessary adjustments. After video recording, post-processing can be performed, such as video editing, image quality enhancement, and adding special effects, to further optimize the viewing experience. In practical applications, the camera system can be tested and debugged multiple times based on this embodiment to ensure its accuracy and stability. This may include, but is not limited to, testing the system's performance in different scenarios and adjusting parameters to achieve optimal results.

[0068] Based on the above embodiments and optional embodiments, this application proposes an implementation method for an optional video acquisition method, the method comprising:

[0069] Step S1, visual detection and tracking of the target object, specifically includes:

[0070] S11. During the video acquisition process, computer vision technology and algorithms (such as face recognition and eye tracking algorithms) are used to detect the gaze of the target object in real time in order to identify the eyes of the target object and determine the gaze direction of the target object, including the direction of the gaze and the focus.

[0071] S12, if the target object is detected to be outside the camera's shooting range, the gaze signal of the target object is collected by the sensor; the direction of the camera is adjusted based on the gaze signal so that the target object is within the camera's shooting range, and the gaze direction of the target object is determined based on the same processing method as in step S11.

[0072] Step S2, camera orientation control, specifically includes:

[0073] Based on the target object's line of sight and a pre-defined visual range, control signals are generated to automatically adjust the camera's direction and focal length. The camera receives control signals through a driver and adjusts them accordingly, enabling the camera to follow the target object's line of sight in real time.

[0074] Specifically, the preset visual range can be a 120-degree field of view of the target object. If the camera is within the visual range and the target object's line of sight, a control signal is generated to adjust the camera's direction and focus; otherwise, no adjustment is made. By setting the visual range, the camera's adjustment range can be limited, avoiding frequent malfunctions when camera adjustments are not necessary.

[0075] Step S3, camera dynamic angle adaptation, specifically includes:

[0076] Based on changes in the target subject's line of sight and shooting requirements, the camera's tilt and angles are automatically adjusted to ensure the optimal shooting angle is always achieved. This includes the following sub-steps:

[0077] S31, Set the corresponding adjustment rules, wherein the adjustment rules are used to indicate the correspondence between the changing direction of the target object's line of sight and the changing angle of the camera's pitch.

[0078] S32, based on the target object's line of sight change information and adjustment rules, determine whether the camera's elevation and depression angles need to be adjusted. For example, if the target object's line of sight is downward and the elevation angle with the camera exceeds a certain angle, it is considered that the elevation angle needs to be increased by a predetermined angle; if the target object's line of sight is upward and exceeds a certain angle, it is considered that the elevation angle needs to be decreased by a predetermined angle.

[0079] S33, based on the judgment result, adjust the camera's elevation and depression angles by controlling the camera's driver. This process can be achieved by sending control signals to the camera, which may include parameters such as the adjusted angle value and speed.

[0080] During video recording, the camera continuously captures video. A combination of dynamic angle adaptation and gaze feedback ensures that the captured content remains consistently high-quality.

[0081] Step S4, gaze feedback, specifically includes:

[0082] When the camera angle changes, the operator receives real-time gaze feedback via a small display screen or headphones. This feedback can include information such as the camera's angle, position, and current status, allowing the operator to understand and make necessary adjustments.

[0083] Step S5, post-processing, specifically includes:

[0084] After the video is filmed, some post-processing work may be required, such as video editing, enhancing image quality, and adding special effects, to further optimize the viewing experience.

[0085] Step S6, testing and debugging, specifically includes:

[0086] In practical applications, the camera system can be tested and debugged multiple times to ensure its accuracy and stability. This can include, but is not limited to, testing the system's performance in different scenarios and adjusting parameters to achieve optimal results.

[0087] This embodiment provides a video capture method based on visual tracking. It utilizes gaze and focus locking, and defines a visual range area to adapt to visual tracking, such as capturing video within a 120-degree visual range of the subject. During video capture, dynamic angle adaptation is performed, providing gaze feedback when the camera changes angles from different elevations or downward views. This improves the effectiveness of video capture based on visual tracking.

[0088] It should be noted that in this embodiment, normal shooting of the target object can be achieved by adjusting the camera direction when the target object is not within the shooting range; by setting a visual range area, the adjustment range of the camera can be limited, avoiding frequent malfunctions of the camera when no camera adjustment is needed; by generating control signals and adjusting the camera direction when the line of sight changes significantly, the frequency of camera adjustments can be reduced, avoiding unnecessary adjustments; by adjusting the azimuth angle of the camera to achieve horizontal and vertical movement of the camera lens when the target object's line of sight changes horizontally or vertically, the lens can be aligned with the target object's current line of sight; by adjusting the azimuth angle or pitch angle accordingly when the difference in azimuth angle or pitch angle is large, unnecessary adjustments can be avoided, reducing the frequency of adjustments; by automatically adjusting the focal length according to the change in distance between the target object and the camera, and simultaneously adjusting the camera direction and focal length, generating control signals for simultaneous adjustment of the camera direction and focal length, the camera focal length can be adjusted while capturing the area being looked at by the target object, thereby maintaining optimal image quality.

[0089] It should be noted that the video acquisition method provided in this application, during the video acquisition process using a camera, detects whether the target object is within the camera's shooting range; if the target object is within the shooting range, it acquires the target object's line of sight direction; based on the line of sight direction, it generates a control signal, wherein the control signal at least indicates: the direction the camera needs to adjust, and the adjustment range of the direction, the direction including azimuth angle and / or pitch angle; and controls the camera to adjust its direction according to the control signal, so that the camera can acquire video along the line of sight direction, thus solving the problem in related technologies where cameras cannot achieve real-time tracking shooting and the video shooting effect is poor. This achieves the goal of automatically adjusting the camera direction through visual tracking during video shooting, realizing the effect of improving video shooting quality while achieving real-time tracking shooting.
