Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of image processing technology, and in particular to a shooting method, device, system, storage medium, and computer program product. Background Art
[0002] Frame rate indicates the frequency of video frames captured by a camera. Frame rate is measured in frames per second (FPS). The higher the frame rate, the smoother the video appears to the human eye. Conversely, the lower the frame rate, the more severe the video's perceived stuttering.

[0061] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
[0062] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the corresponding data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.
[0063] Before introducing the specific embodiments of the present disclosure in detail, the application scenarios of the present disclosure are first described. The present disclosure can be applied to video shooting scenarios, wherein the frame rate is used to indicate the frequency of the pictures of the video shot by the shooting device. The unit of the frame rate is the number of frames per second (FPS). The higher the frame rate used by the shooting device when shooting the video, the smoother the video is perceived by the human eye. Conversely, the lower the frame rate used by the shooting device when shooting the video, the more serious the video freeze phenomenon perceived by the human eye.
[0064] At present, under normal circumstances, shooting equipment will use a fixed frame rate to shoot the target and collect video. However, during the shooting process, if a high frame rate is used to shoot a target object with a slower movement speed, more redundant images will be collected, increasing the power consumption of the shooting equipment. Alternatively, if a low frame rate is used to shoot a target object with high-speed movement, it will not be possible to fully capture the target's motion information, resulting in the target's movement in the collected video being unsmooth.
[0065] In related technologies, cameras can re-encode captured video to generate videos at different frame rates. However, the lower frame rate used by cameras results in the loss of motion information, which cannot be compensated for through subsequent encoding, resulting in the continued presence of choppy video.
[0066] To overcome the technical problems existing in the above-mentioned related technologies, the present disclosure provides a shooting method, device, system, storage medium, and computer program product. These methods, while shooting a target object at a preset frame rate, obtain the target object's motion parameters; determine a target frame rate corresponding to the motion parameters; adjust the preset frame rate to the target frame rate, and shoot at the target frame rate. This method improves the clarity of video capture and ensures smooth video capture by obtaining the target object's motion parameters and then determining the corresponding target frame rate based on the motion parameters.
[0067] The present disclosure is described below with reference to specific embodiments.
[0068] Figure 1 FIG. 1 is a flow chart showing a shooting method according to an exemplary embodiment. Figure 1 As shown, the method is used in a terminal, which may include a mobile phone, a tablet computer, a laptop computer, a virtual reality (VR) device, an augmented reality (AR) device, a mixed reality (MR) device, an extended reality (ER), a vehicle-mounted camera device, etc. The method includes the following steps.
[0069] In step S11 , when a target object is photographed at a preset frame rate, motion parameters of the target object are obtained.
[0070] The frame rate is used to indicate the frequency at which a shooting device shoots video images.
[0071] In this step, the terminal may capture the target object using a preset frame rate. The preset frame rate may be a user-preset frame rate that is neither too high to affect the power consumption of the terminal's camera nor too low to fully capture the target's motion information. Accordingly, a relatively intermediate frame rate value is selected. The terminal may then obtain the motion parameters of the captured target object while capturing the target object using the preset frame rate.
[0072] In step S12, a target frame rate corresponding to the motion parameter is determined.
[0073] The motion parameter may be used to indicate the speed of the target object's motion.
[0074] In this step, after obtaining the motion parameter, the terminal can first determine the specific value of the motion parameter, and then determine the speed of the target object's movement based on the value of the motion parameter. When it is determined that the target object is moving faster, the corresponding preset frame rate with a higher value can be used as the target frame rate, or when it is determined that the target object is moving slower, the corresponding preset frame rate with a smaller value can be used as the target frame rate.
[0075] In step S13, the preset frame rate is adjusted to the target frame rate, and shooting is performed according to the target frame rate.
[0076] The above technical solution obtains the target object's motion parameters while shooting it at a preset frame rate; determines the target frame rate corresponding to the motion parameters; adjusts the preset frame rate to the target frame rate, and shoots at the target frame rate. This improves the clarity of video capture and ensures smooth video recording by obtaining the target object's motion parameters and then determining the target frame rate based on the motion parameters.
[0077] In some embodiments, the motion parameter includes the relative motion speed of the target object relative to the terminal; Figure 2 As shown, the above step S12 may include the following steps.
[0078] In step S121 , a target speed range corresponding to the relative motion speed is determined from a plurality of preset speed ranges.
[0079] In this step, a plurality of preset speed ranges may be pre-set first, and then the speed range in which the relative motion speed of the target object relative to the terminal is located is determined, and the speed range is used as the target speed range.
[0080] In step S122, the target frame rate corresponding to the target speed range is determined from a plurality of preset frame rates through a preset corresponding relationship.
[0081] The preset corresponding relationship includes a corresponding relationship between the plurality of preset speed ranges and preset frame rates.
[0082] In one possible implementation, the preset frame rate corresponding to each preset speed range can be determined in advance, wherein the correspondence between the multiple preset speed ranges and the preset frame rates can be that the larger the speed value included in the preset speed range, the larger the corresponding preset frame rate value. In this way, when shooting a target object with high-speed movement, the motion information of the target can be fully captured. In addition, the smaller the speed value included in the preset speed range, the smaller the corresponding preset frame rate value. In this way, when shooting a target object with a slower movement speed, the collection of more redundant images can be avoided, thereby reducing the power consumption of the shooting equipment.
[0083] By adopting the above technical solution, by determining the target frame rate corresponding to the target speed range from multiple preset frame rates, it is possible to achieve the technical effect of improving the clarity of video shooting and ensuring the smoothness of video shooting.
[0084] In some embodiments, the terminal includes a first camera and a second camera. When the first camera shoots the target object at a preset frame rate, the first camera can be used to obtain the motion parameters determined by the second camera.
[0085] Optionally, the asynchronous event determined by the second camera may be first acquired, and then, based on the asynchronous event output by the second camera, the motion parameter of the target object in the asynchronous event may be determined, where the motion parameter is used to represent the relative motion speed between the target object and the second camera.
[0086] Optionally, the second camera comprises a dynamic vision sensor DVS event camera.
[0087] For example, the inertial data corresponding to the second camera can be first obtained; then, when the event duration corresponding to the asynchronous event is greater than or equal to a preset time threshold, the motion parameters of the target object in the asynchronous event are determined based on the event speed corresponding to the asynchronous event and the inertial data.
[0088] In some embodiments, the target frame rate may be switched to the preset frame rate in response to a motion stop instruction sent by the second camera.
[0089] By adopting the above technical solution, the motion parameters of the target object can be obtained, and then the corresponding target frame rate can be determined based on the motion parameters, which can improve the clarity of video shooting and ensure the smoothness of video shooting.
[0090] Figure 3 is a flow chart showing another shooting method according to an exemplary embodiment. Figure 3 As shown, the method is used in a terminal, and the method includes the following steps.
[0091] In step S21 , when the first camera shoots the target object at a preset frame rate, the first camera obtains the asynchronous event determined by the second camera.
[0092] In step S22, inertial data corresponding to the second camera is obtained.
[0093] In step S23 , when the event duration corresponding to the asynchronous event is greater than or equal to the preset time threshold, the motion parameters of the target object in the asynchronous event are determined according to the event speed corresponding to the asynchronous event and the inertia data.
[0094] In step S24, a target speed range corresponding to the relative motion speed is determined from a plurality of preset speed ranges.
[0095] In step S25, the target frame rate corresponding to the target speed range is determined from a plurality of preset frame rates through a preset corresponding relationship, where the preset corresponding relationship includes a corresponding relationship between the plurality of preset speed ranges and preset frame rates.
[0096] In step S26, the preset frame rate is adjusted to the target frame rate, and shooting is performed according to the target frame rate.
[0097] In step S27 , in response to the motion stop instruction sent by the second camera, the target frame rate is switched to the preset frame rate.
[0098] By acquiring the target object's motion parameters while shooting it at a preset frame rate, determining a target frame rate corresponding to the motion parameters, adjusting the preset frame rate to the target frame rate, and shooting at the target frame rate, the clarity of the video can be improved and the smoothness of the video can be ensured.
