Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0055] At present, with the development of camera hardware technology, some camera manufacturers have launched a variety of sports cameras, whose shooting components can be separated from the control terminal and shoot independently. However, when shooting separately, existing sports cameras can only mechanically use a single preset link to transmit image data, and cannot adjust the image transmission link and the transmitted image in real time according to the specific situation of the transmission link, resulting in poor image transmission rate and transmission image quality, making it difficult for users to adjust the camera in real time according to the transmitted image, resulting in poor shooting effect.

[0056] Based on this, the present application proposes an image transmission method, device, equipment and computer-readable storage medium to solve the technical problem in the prior art that the shooting equipment cannot adjust the image transmission link and the transmitted image in real time according to the specific situation of the transmission link to ensure transmission efficiency and transmission image quality.

[0057] like Figure 1 As shown, Figure 1 The following is a scene diagram of the image transmission method of the embodiment of the present application. In the embodiment of the present invention, the image transmission scene is applied to a shooting system, which at least includes a shooting component 100 (an image transmission device is integrated in the shooting component 100) and a preset control terminal 200, wherein the shooting component 100 is an intelligent terminal that can execute shooting or video recording instructions and communicate with the preset control terminal 200 through a specified transmission link. The shooting component 100 can be a shooting device with a shooting function such as a camera, a panoramic camera, a sports camera, a SLR camera, a gimbal, a smart phone, a smart tablet, etc. The preset control terminal 200 can be an intelligent control terminal that can interact with the shooting component through a wired transmission link or a wireless transmission link. The preset control terminal 200 can be a control terminal such as a charging box, a smart remote control, a smart phone, a smart tablet, a smart wearable device, a smart watch, a smart headset, a smart glasses, etc. corresponding to the shooting component. Optionally, the preset control terminal 200 can be a control terminal that can be combined with the shooting component 100 for shooting, and can also be a mobile terminal such as a mobile phone, a tablet computer, and a wearable smart device that is installed with a control application corresponding to the shooting component and uses the control application to access the shooting component. Optionally, the control terminal may be a charging component of the shooting component or a detachably connected remote control terminal.

[0058] Specifically, the shooting component 100 can establish a communication connection with each preset control terminal 200 through a target transmission link, and drive the preset control terminal 200 to display a preview image of the image stream acquired by the shooting component 100 during the shooting process.

[0059] Understandably, Figure 1The shooting system in the image transmission method scenario shown, the devices included in the shooting system do not constitute a limitation on the embodiments of the present invention, that is, the number of devices and types of devices included in the image transmission method scenario, or the number of devices and types of devices included in each device do not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be regarded as equivalent replacements or derivatives of the technical solution claimed to be protected in the embodiments of the present invention.

[0060] The shooting component 100 in the embodiment of the present invention is mainly used for: obtaining the image stream captured by the shooting component; obtaining the connection status between the shooting component and a preset control end, and determining the target control end; obtaining the target transmission link corresponding to the target control end, processing the image stream according to the link parameters of the target transmission link, and sending the processed image stream to the target control end.

[0061] The embodiments of the present application provide an image transmission method, device, shooting component and computer-readable storage medium, which are described in detail below.

[0062] It can be understood by those skilled in the art that Figure 1 The application environment shown in is only one of the application scenarios related to the present application solution and does not constitute a limitation on the application scenario of the present application solution. Other application environments may also include Figure 1 More or less than shown, or image transmission network connection relationship, such as Figure 1 Only one shooting component is shown. It can be understood that the scenario of the image transmission method can also include one or more shooting components and control terminals, which are not specifically limited here. The shooting component 100 can also include a memory for storing image streams and other data.

[0063] It should be noted that Figure 1 The scene diagram of the image transmission method shown is only an example. The scene of the image transmission method described in the embodiment of the present invention is to more clearly illustrate the technical solution of the embodiment of the present invention, and does not constitute a limitation on the technical solution provided by the embodiment of the present invention.

[0064] like Figure 2 As shown, Figure 2 This is a flow chart of an embodiment of the image transmission method in the embodiment of the present application. The image transmission method includes the following steps 201 to 203:

[0065] 201. Acquire an image stream collected by a shooting component;

[0066] Specifically, during operation, the shooting component can respond to the user's shooting instructions and perform corresponding shooting operations according to the user's shooting instructions, thereby recording or shooting the target scene to obtain an image stream captured by the shooting component.

[0067] Specifically, the shooting instruction also includes shooting mode parameters, and the shooting component can select the corresponding shooting mode for shooting according to the shooting mode parameters, and adjust the shooting parameters of the shooting component during the shooting process, and after the shooting mode is determined and the shooting parameters are set, the target scene is recorded or photographed by responding to the shutter to obtain a captured image stream. Optionally, in a specific embodiment, the shooting component is preset with shooting modes such as normal shooting mode, HDR shooting mode, normal video mode, slow motion video mode, continuous shooting mode and time-lapse shooting mode. The shooting parameters include setting parameters such as exposure compensation, white balance and ISO sensitivity.

[0068] Optionally, the shooting mode and shooting parameters can be automatically set by the shooting component or customized by the user.

[0069] Specifically, after receiving a shooting instruction or a video recording instruction, the shooting component jumps to the shooting interface corresponding to the shooting instruction or the video recording instruction and the shooting mode, and performs a shooting operation for the target scene according to the shooting rules corresponding to the shooting mode on the shooting interface to obtain a shooting image stream corresponding to the target scene. For example, if the shooting component receives a time-lapse shooting instruction and determines that the shooting mode is a time-lapse shooting mode, the shooting component jumps to the time-lapse shooting interface, and starts shooting or recording the target scene after a preset time period to obtain an image stream.

[0070] Optionally, after acquiring the captured image stream, the shooting component can also beautify the image stream through a preset image processing algorithm, that is, identify the image information in the image stream through a preset image processing algorithm, and adjust the image information to achieve an image beautification effect, thereby obtaining the image stream collected by the shooting component. Optionally, the beautification operation may include image processing operations such as AI beauty, filter adjustment, brightness adjustment, contrast adjustment, sharpening operation, image ratio adjustment, and resolution adjustment.

[0071] Optionally, the image stream captured by the shooting component may also be images or videos transmitted from other terminals to the shooting component or images or videos transmitted from other terminals to the shooting component, and images or videos generated after image processing by the shooting component.

[0072] 202. Acquire the connection status between the shooting component and a preset control terminal, and determine a target control terminal;

[0073] Specifically, after acquiring the image stream, the shooting component also acquires the connection status between the shooting component and the preset control terminal.

[0074] Specifically, the shooting component is preset with a connection device form. When the preset control terminal and the shooting component are in a connection state, the shooting component associates the terminal identifier and the connection link of the preset control terminal and stores them in the connection device form. The shooting component determines the connection state between the shooting component and each preset control terminal by reading the terminal identifier and the connection link in the connection device form. Optionally, the connection state includes a connected state and a disconnected state.

[0075] Optionally, in other embodiments, the shooting component further sets a corresponding device connection indicator light for each preset control terminal, and the device connection indicator light is used to characterize the connection status of each preset control terminal. For example, when different preset control terminals are in a connected state with the shooting component, the device connection indicator light corresponding to the preset control terminal is displayed in a first display mode; when the preset control terminal and the shooting component are in an unconnected state, the device connection indicator light corresponding to the preset control terminal is displayed in a second display mode. Among them, the first display mode can be a display mode in which a specified color is always on, for example, the first display mode is a green light that is always on. The second display mode can be a display mode in which a specified color flashes or goes out, for example, the second display mode can be a red light that flashes. The shooting component can customize the first display mode and the second display mode according to the actual application scenario, and this embodiment does not specifically limit this.

[0076] Specifically, after obtaining the connection status of each preset control terminal, the shooting component also determines the target control terminal according to the connection status of each preset control terminal. The target control terminal is a control terminal that has the control authority of the shooting component, can control the shooting component to perform corresponding operations, and preview the image stream of the shooting component.

[0077] The shooting component sets the corresponding connection priority for each preset control terminal in advance, and determines the target control terminal among the preset control terminals in the connected state through the connection priority. That is, the shooting component traverses the connection priority among the preset control terminals in the connected state, and sets the preset control terminal with the highest connection priority as the target control terminal. Among them, the connection priority is a priority parameter that characterizes the control priority between the preset control terminal and the shooting component. The priorities of different categories of preset control terminals are different. In a specific embodiment, the connection priority of the mobile terminal is higher than the connection priority of the control terminal, that is, when the mobile terminal and the control terminal are both connected to the shooting component, the mobile terminal is the target control terminal.

[0078] Optionally, in other embodiments, the shooting component can also obtain the power information and / or signal information of each preset control terminal, and filter the target control terminal among the preset control terminals in the connected state according to the power information and / or signal information. For example, filter the preset control terminal with the highest power among the preset control terminals in the connected state as the target control terminal. Or filter the preset control terminal with a better signal among the preset control terminals in the connected state as the target control terminal.

[0079] Optionally, in one embodiment, if the shooting component detects that the connection status with the mobile terminal is disconnected, the shooting component obtains the connection status of each control terminal and sets the control terminal whose connection status with the shooting component is connected as the target control terminal of the shooting component.

[0080] Optionally, if the connection state between the shooting component and the mobile terminal is a connected state, the shooting component sets the mobile terminal as a target control terminal of the shooting component.

[0081] 203. Acquire a target transmission link corresponding to the target control end, process the image stream according to link parameters of the target transmission link, and send the processed image stream to the target control end.

[0082] Specifically, after determining the target control end of the shooting component, the shooting component obtains the target transmission link corresponding to the target control end, processes the image stream according to the link parameters of the target transmission link, and sends the processed image stream to the target control end for preview display.

[0083] Optionally, in one embodiment, if the target control terminal is a mobile terminal, the shooting component selects the wireless transmission link associated with the mobile terminal as the target transmission link corresponding to the target control terminal. The image stream is transmitted through the target transmission link. To save power consumption, after determining the target control terminal, the shooting component stops transmitting the image stream to other preset control terminals, and generates a switch preview terminal prompt page on the display interface of the preset control terminal. Optionally, the wireless transmission link includes a Bluetooth transmission link, a WiFi transmission link, and a 2.4G transmission link.

[0084] Optionally, if the shooting component determines that the target control end is a control terminal and obtains the target transmission link corresponding to the control terminal, the target transmission link corresponding to the control terminal includes a wireless transmission link and a wired transmission link. Optionally, the target transmission link includes a wireless transmission link and a wired transmission link. In a specific embodiment, the wireless transmission link includes a WIFI transmission link and a Bluetooth transmission link; the wired transmission link is a USB transmission link.

[0085] Optionally, in one embodiment, when the shooting component determines the target control end and the target transmission link of the target control end is a wireless transmission link, the shooting component also determines the target control link corresponding to the image parameters and / or preview requirements of the image stream.

[0086] Optionally, if the file size parameter in the image parameters of the image stream exceeds a preset file threshold, that is, the file of the image stream is large and the image stream cannot be transmitted using the Bluetooth transmission link, the shooting component selects the WiFi transmission link as the target transmission link corresponding to the target control end.

[0087] Optionally, if the preview requirement of the target control end is a high-definition requirement, that is, the target control end needs to display a high-definition preview image associated with the image stream on a preset display interface, the shooting component selects a WiFi transmission link as the target transmission link corresponding to the target control end.

[0088] Optionally, if the file size in the image parameters of the target control terminal does not exceed a preset file threshold, or the preview requirement of the target control terminal does not meet the low-quality preview requirement, the shooting component selects a Bluetooth transmission link to transmit the image stream.

[0089] Optionally, in a specific embodiment, after determining that the target control end is a control terminal, the shooting component also obtains the in-place state of the shooting component, and selects the target transmission link corresponding to the control terminal according to the in-place state of the shooting component. The in-place state is a connection state that indicates whether the shooting component is in a wired connection with the control terminal; the in-place state includes an integrated state and a separated state.

[0090] Specifically, when the shooting component transmits the image stream to the target control terminal based on the target transmission link, it also adjusts the image stream according to the link parameter of the target transmission link to obtain a processed image stream, and transmits the processed image stream to the target control terminal. The link parameter is a parameter that characterizes the link signal state of the target transmission link. In a specific embodiment, the link parameter includes signal strength and link bandwidth.

[0091] Optionally, the shooting component can adjust the resolution information of the image stream according to the link parameter to obtain an image stream with increased or reduced resolution. That is, during the image transmission process, the shooting component monitors the link parameters to identify the link status of the target link, and automatically increases the resolution of the image stream when the link status is good, and automatically reduces the resolution of the image stream when the link status is poor.

[0092] Optionally, the shooting component can adjust the bit rate information of the image stream according to the link parameter to obtain a processed image stream.

[0093] Optionally, the shooting component can also perform frame dropping processing on the image stream according to the link parameters to obtain a processed image stream.

[0094] Specifically, after processing the image stream through the link parameters, the shooting component transmits the processed image stream to the target control terminal based on the target transmission link, and displays a preview image corresponding to the processed image stream in the target display area of ​​the target control terminal.

[0095] In this embodiment, the shooting component obtains the image stream collected by the shooting component by responding to the image transmission request; obtains the connection status between the shooting component and the preset control terminal, determines the target control terminal; obtains the target transmission link corresponding to the target control terminal, processes the image stream according to the link parameters of the target transmission link, and sends the processed image stream to the target control terminal. By identifying the connection status between the shooting component and the preset control terminal, the corresponding transmission link is selected for image / video transmission, so as to ensure the efficiency of image transmission and the quality of transmitted images in various situations.

[0096] like Figure 3 As shown, Figure 3 This is a flow chart of an embodiment of adjusting the transmitted image stream according to the link parameters in the image transmission method provided in the embodiment of the present application. Specifically, based on the above embodiment, the image transmission method further includes: Steps 301 to 303:

[0097] 301. Identify the link state of the target transmission link according to the signal strength and the link bandwidth;

[0098] 302. Query a code rate database to obtain a target transmission code rate corresponding to the link state in the code rate database;

[0099] 303. Adjust the bit rate information of the image stream according to the target transmission bit rate to obtain a processed image stream, and send the processed image stream to the target control terminal based on the target transmission link.

[0100] Based on the above embodiments, in this embodiment, when the shooting component determines that the target transmission link between the shooting component and the target control end is a wireless transmission link, the image stream is transmitted according to the wireless transmission link, and the link parameters of the wireless transmission link are obtained in real time during the transmission process, and the transmission state of the image stream is adjusted according to the link parameters, wherein the link parameters include parameters characterizing the link signal state, such as the signal strength and link bandwidth of the wireless transmission link.

[0101] Specifically, when the target transmission link is a wireless transmission link, as the distance between the shooting component and the control terminal serving as the target control end gradually increases, the signal state of the wireless transmission link also weakens. The transmission state of the image stream is affected by the signal state of the wireless transmission link. To ensure that the image stream can be transmitted to the target control end, the shooting component collects the link parameters of the wireless transmission link in real time during the transmission process, and adjusts the transmission bit rate of the image stream according to different link parameters, or processes non-key frames of the image stream to obtain a processed image stream.

[0102] Specifically, when the shooting component uses a wireless transmission link to transmit an image stream, it obtains an initial transmission bit rate based on the current link status of the wireless transmission link, and uses the initial transmission bit rate to transmit the image stream. During the subsequent transmission process, the signal strength and link bandwidth in the wireless transmission link are collected in real time, and the link status of the target transmission link is identified based on the signal strength and link bandwidth.

[0103] Specifically, the shooting component compares the acquired signal strength with a preset signal strength threshold, and compares the acquired link bandwidth with a preset bandwidth threshold, so as to determine the link status of the target transmission link. Optionally, the signal strength threshold includes a first strength threshold and a second strength threshold; the bandwidth threshold includes a first bandwidth threshold and a second bandwidth threshold. The first strength threshold is a signal strength threshold that characterizes that the transmission link is in a weak signal state; the second strength threshold is a signal strength threshold that characterizes that the wireless transmission link is in a no-signal state and cannot meet the image transmission requirements. The first bandwidth threshold is a link bandwidth threshold that characterizes that the wireless transmission link is in a low bandwidth; the second bandwidth threshold is a minimum link bandwidth value that characterizes the image transmission requirements of the wireless transmission link.

[0104] Optionally, if the signal strength of the wireless transmission link is greater than the first strength threshold, the shooting component determines that the distance between the shooting component and the target control terminal is relatively close, and the signal state of the wireless transmission link is an excellent signal state. If the signal strength of the wireless transmission link is less than the first strength threshold and greater than the second strength threshold, the shooting component determines that the signal state of the wireless transmission link is a general signal state; if the signal strength of the wireless transmission link is less than the second strength threshold, the shooting component determines that the signal of the wireless transmission link is poor and cannot meet the image transmission requirements.

[0105] Optionally, if the link bandwidth of the wireless transmission link is greater than the first bandwidth threshold, the shooting component determines that the distance between the shooting component and the target control terminal is relatively close, and the bandwidth state of the wireless transmission link is a high bandwidth state. If the link bandwidth of the wireless transmission link is less than the first bandwidth threshold and greater than the second bandwidth threshold, the shooting component determines that the bandwidth state of the wireless transmission link is a medium bandwidth state; if the link bandwidth of the wireless transmission link is less than the second bandwidth threshold, the shooting component determines that the bandwidth of the wireless transmission link is relatively weak and does not meet the minimum bandwidth requirement, and cannot meet the image transmission requirement.

[0106] Specifically, after obtaining the target transmission bit rate corresponding to the link state, the shooting component encodes and compresses the image stream based on the preset bit rate adjustment algorithm and the target transmission bit rate, thereby adjusting any one or more of the resolution, compression parameters or frame rate of the image stream, so that the transmission bit rate of the image stream is the same or close to the target transmission bit rate, so as to generate a processed image stream, and drive the target transmission link to transmit the processed image stream to the target control end for preview display, so as to automatically increase the bit rate when the link state of the target transmission link is better, and automatically reduce the bit rate when the link state of the target transmission link is worse. Optionally, the preset bit rate adjustment algorithm can be a bit rate adjustment algorithm such as a bit rate control algorithm or an adaptive bit rate adjustment algorithm.

[0107] Optionally, if the link bandwidth in the wireless transmission link is less than a preset second bandwidth threshold, and / or the signal strength is less than a preset second strength threshold, that is, the current link state of the wireless transmission link cannot meet the minimum transmission requirement of the image stream, the shooting component stops transmitting the image stream;

[0108] After stopping transmission of the processed image stream, the shooting component also obtains the updated link bandwidth and updated signal strength in the wireless transmission link. If the updated link bandwidth is greater than the second bandwidth threshold, and / or the updated signal strength is greater than the preset second strength threshold, the processed image stream is resumed to be transmitted to the target control end according to the preset transmission bit rate, and a preview image of the processed image stream is displayed in the target display area of ​​the target control end.

[0109] In this embodiment, the shooting component obtains the link parameters of the wireless transmission link, the link parameters include signal strength and link bandwidth; adjusts the image stream according to the signal strength and the link bandwidth to obtain a processed image stream; transmits the processed image stream to the target control terminal based on the target transmission link, and displays a preview image of the processed image stream in the target display area of ​​the target control terminal. In the process of image transmission through the target link transmission, the transmission bit rate is automatically adjusted according to the link status, ensuring the stability of image transmission and improving the preview effect.

[0110] like Figure 4 As shown, Figure 4 This is a flow chart of an embodiment of adjusting an image stream according to signal strength and link bandwidth in an image transmission method provided in an embodiment of the present application. Specifically, the image transmission method further includes steps 401 to 402:

[0111] 401. If the link bandwidth in the wireless transmission link is less than a preset first bandwidth threshold, and / or the signal strength is less than a preset first strength threshold, image frame recognition is performed on the image stream to obtain a first image frame in the image stream; the first image frame is an image frame containing key image information of the image stream;

[0112] 402. Filter the second image frames in the image stream except the first image frame to obtain a processed image stream including the first image frames.

[0113] Based on the above embodiments, in this embodiment, after acquiring the link bandwidth and signal strength of the wireless transmission link, the shooting component further adjusts the image stream according to the link bandwidth and signal strength to generate a processed image stream.

[0114] Specifically, the shooting component compares the link bandwidth in the wireless transmission link with the first bandwidth threshold, and / or compares the signal strength with the preset first strength threshold, so as to determine the link state of the wireless transmission link. The first bandwidth threshold is a link bandwidth threshold that indicates that the wireless transmission link is in a low bandwidth; the first strength threshold is a signal strength threshold that indicates that the transmission link is in a weak signal state.

[0115] Optionally, if the link bandwidth in the wireless transmission link is less than the first bandwidth threshold, or the signal strength is less than the first strength threshold, the shooting component determines that the link state of the wireless transmission link is poor, and optimizes the image stream to obtain a processed image stream.

[0116] Specifically, the shooting component reads the encoding method of the image stream. If the encoding method is a target encoding method for storing the key image information of the image stream in a designated key image frame, the shooting component performs image frame recognition on the image stream to obtain a first image frame and a second image frame in the image stream, wherein the first image frame is a key image frame containing the key image information of the image stream, and the second image frame is an image frame that does not contain the key image information of the image stream.

[0117] Optionally, after determining that the link state of the wireless transmission link is poor and the image stream needs to be optimized, the shooting component extracts features from each image frame in the image stream, compares image change information in each image frame, and uses an image frame whose image change information is greater than a preset image threshold as the first image frame. Use an image frame whose image change information is less than the preset image threshold as the second image frame.

[0118] Specifically, after acquiring the first image frame and the second image frame in the image stream, the shooting component performs frame discarding processing on the image stream, that is, filters the second image frame except the first image frame in the image stream to obtain a processed image stream including the first image frame.

[0119] After acquiring the processed image stream, the shooting component transmits the processed image stream to the target control end for display based on the target transmission link.

[0120] In this embodiment, when the shooting component detects that the link bandwidth in the wireless transmission link is less than the preset second bandwidth threshold, and / or the signal strength is less than the preset second strength threshold, it stops transmitting the processed image stream; obtains the updated link bandwidth and updated signal strength in the wireless transmission link, and if the updated link bandwidth is greater than the second bandwidth threshold, and / or the updated signal strength is greater than the preset second strength threshold, it resumes transmitting the processed image stream to the target control terminal according to the preset transmission bit rate, and displays a preview image of the processed image stream in the target display area of ​​the target control terminal. It is possible to judge the link status through the link bandwidth and signal strength, and perform frame dropping processing on the image stream when the link status is poor, thereby improving the stability and efficiency of image transmission.

[0121] like Figure 5 As shown, Figure 5 A flowchart of an embodiment of selecting a target transmission link according to an in-place state in an image transmission method provided in an embodiment of the present application when the target control end is a control terminal, specifically, the image transmission method further includes steps 501 to 504:

[0122] 501. If the target control end is a control terminal, and the control terminal is detachably connected to the shooting component, read first sensor data of the shooting component and second sensor data of the control terminal;

[0123] 502. Identify the in-position status of the photographing component according to the first sensor data and the second sensor data;

[0124] 503. If the in-place state of the shooting component is an integrated state, setting a preset wired transmission link as a target transmission link of the shooting component;

[0125] 504. If the in-place state of the shooting component is a separated state, setting a preset wireless transmission link as a target transmission link of the shooting component.

[0126] Based on the above embodiments, in this embodiment, when the shooting component determines that the target control end is a control terminal, it also identifies the in-place status of the shooting component and the control terminal, and selects the target transmission link between the shooting component and the control terminal according to the in-place status.

[0127] Specifically, Figure 6 As shown, Figure 6 It is a schematic diagram of the construction of an embodiment of the combination of a shooting component and a control terminal in the embodiment of the present application, including a shooting component 101 and a control terminal 102. The control terminal 102 is provided with a mounting portion adapted to the shooting component 101, for mounting the shooting component 101, so as to realize an integrated setting of the shooting component 101 and the control terminal 102. At this time, the shooting component 101 and the control terminal 102 have the same posture and position. The shooting component 101 can also be separated from the control terminal 102 and shoot independently. When the shooting component 101 is separated from the control terminal 102, the shooting component 101 is in a separated state when shooting separately from the control terminal 102; when the shooting component 101 is located in the control terminal 102 to perform shooting, the shooting component 101 is in an integrated state when shooting. It is worth noting that Figure 6 The forms of the shooting component 101 and the control terminal 102 shown in the figure do not constitute a limitation on the shooting component 101 and the control terminal 102. The shooting component 101 may also be a square, round or other form of a camera component, and the control terminal 102 may also be a square structure, round structure or other form of a control terminal 102 component arranged corresponding to the shooting component 101. Moreover, the control terminal 102 may not be provided with a warehouse structure, but may be connected to the shooting component 101 by setting a combination component on a plane. This embodiment does not make any specific limitation on this.

[0128] Optionally, in one embodiment, the shooting system obtains first sensor data of the shooting component and second sensor data of the control terminal, and identifies the in-position state of the shooting component through the first sensor data and the second sensor data. The first sensor data is sensor data collected by a first sensor arranged in the shooting component, and the first sensor may be one or more sensors such as a gyroscope, a distance sensor, and a position sensor. The second sensor data is sensor data collected by a second sensor arranged in the control terminal. The first sensor may be one or more sensors such as a gyroscope, a distance sensor, and a position sensor.

[0129] Optionally, if the first sensor data matches the second sensor data, that is, the first sensor data is the same as the second sensor data, the shooting system determines that the in-place state of the shooting component is an integrated state, and sets the wired transmission link as the target transmission link of the image stream.

[0130] Optionally, if the first sensor data does not match the second sensor data, that is, there is sensor data in the first sensor data that is different from the second sensor data, such as different gyroscope parameters, different distance sensor parameters and exceeding a preset distance threshold, and different position sensor parameters, any one or more of the following scenarios occurs, the shooting system determines that the in-place state of the shooting component is a separated state, and sets the wireless transmission link as the target transmission link of the image stream.

[0131] Optionally, in another embodiment, the shooting system can also determine the in-place state of the shooting component by detecting the USB connection state in the shooting component and the control terminal, and obtain the target transmission link corresponding to the in-place state, that is, the USB connection link in the control terminal is provided with a target pin, and the voltage parameter of the target pin is detected and the voltage parameter is converted into an analog-to-digital format to obtain the in-place state parameter, and the in-place state parameter is compared with the preset parameter threshold value, and the in-place state of the shooting component is determined according to the comparison result. In a specific embodiment, the target pin is a pogopin pin; the in-place state parameter is a discrete digital signal obtained by converting the voltage parameter into an analog-to-digital format, which characterizes the in-place state of the shooting component.

[0132] Optionally, if the in-place status parameter is greater than or equal to the preset parameter threshold, the shooting component determines that the in-place status of the shooting component and the control terminal are an integrated state, that is, the USB connection status of the shooting component and the control terminal is in a connected state, and determines that the target transmission link between the shooting component and the control terminal is a wired transmission link.

[0133] Optionally, if the in-place state parameter is less than the preset parameter threshold, the shooting component determines that the in-place state of the shooting component and the control terminal is a separated state, that is, the USB connection state between the shooting component and the control terminal is in an unconnected state, and determines that the target transmission link between the shooting component and the control terminal is a wireless transmission link.

[0134] Optionally, the shooting component can also realize in-situ detection by one or more combinations of micro switches, voltage or current detection, Hall sensors, pressure sensors, capacitive sensors, infrared sensors and other devices.

[0135] In this embodiment, after determining that the control terminal is the target control terminal, the shooting component reads the first sensor data of the shooting component and the second sensor data of the control terminal; identifies the in-place state of the shooting component according to the first sensor data and the second sensor data; if the in-place state of the shooting component is an integrated state, sets the preset wired transmission link as the target transmission link of the shooting component; if the in-place state of the shooting component is a separated state, sets the preset wireless transmission link as the target transmission link of the shooting component. The target transmission link of the target control terminal is automatically selected by detecting the in-place state of the shooting component and the control terminal.

[0136] like Figure 7 As shown, Figure 7 This is a flow chart of an embodiment of link change in the image transmission method provided in the embodiment of the present application. Specifically, the image transmission method further includes steps 601 to 604:

[0137] 601. Read first updated sensor data of the shooting component and second updated sensor data of the control terminal;

[0138] 602. Identify the update in-place state of the shooting component according to the first update sensor data and the second update sensor data;

[0139] 603. If the update in-place state is different from the in-place state corresponding to the target transmission link, obtain an update transmission link corresponding to the update in-place state;

[0140] 604. Transmit the image stream based on the updated transmission link, and display a preview image of the image stream.

[0141] Based on the above embodiments, in this embodiment, after determining the target transmission link of the target control end, the shooting component also monitors the update status of the shooting component in real time, switches the update transmission link of the image stream through the update status, and transmits the image stream through the update transmission link.

[0142] Specifically, the shooting component reads the first update sensor data of the shooting component and the second update sensor data of the base layer, and determines the update status of the shooting component according to the first update sensor data and the second update sensor data. The first update sensor data is the current sensor data collected by the first sensor disposed in the shooting component; the second update sensor data is the current sensor data collected by the second sensor disposed in the control terminal.

[0143] Optionally, if the photographing component detects that the first update sensor data and the second update sensor data match within a preset time, that is, the first sensor data is the same as the second sensor data, then it is determined that the update in-place state of the photographing component is an integrated state.

[0144] Optionally, if the shooting component detects within a preset time that the first updated sensor data and the second updated sensor data do not match, that is, the first updated sensor data is different from the second updated sensor data, and the number of changes exceeds a preset update number threshold, then the update in-place state of the shooting component is determined to be a separated state.

[0145] Specifically, when the shooting component obtains the updated in-place state of the shooting component, if the updated in-place state is different from the in-place state corresponding to the current target transmission link, the shooting component switches the target transmission link to the updated transmission link corresponding to the updated in-place state, thereby realizing the switching of the transmission link when the in-place state of the shooting component changes.

[0146] Specifically, after acquiring the update transmission link of the shooting component, the shooting component transmits the image stream according to the update transmission link, and displays a preview image of the image stream on the target control terminal.

[0147] In this embodiment, the shooting component reads the first update sensor data of the shooting component and the second update sensor data of the control terminal; identifies the update status of the shooting component according to the first update sensor data and the second update sensor data; if the update status is different from the status corresponding to the target transmission link, obtains the update transmission link corresponding to the update status; transmits the image stream based on the update transmission link, and displays the preview image of the image stream. The real-time acquisition of the update status of the shooting component is achieved, and the transmission link is automatically switched when the update status changes, so as to improve the stability of image stream transmission.
