All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The flow diagrams depicted in the figures are merely illustrative and do not necessarily include all of the elements and operations/steps, nor do they necessarily have to be performed in the order depicted. For example, some operations/steps may be decomposed, combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

The embodiment of the application provides a device control method, an image display method, a device and a storage medium. The device may include an image capturing device, a display terminal, a movable platform, and the like, the storage medium is a computer-readable storage medium, the types of the image capturing device, the display terminal, and the movable platform may be flexibly set according to actual needs, and specific contents are not limited herein. For example, the image capturing device may be a camera having a shutter function (e.g., an infrared camera, or the like), the display terminal may include a terminal having a display function, such as a mobile phone or a computer, and the movable platform may include an aircraft (e.g., an unmanned aerial vehicle), a robot, a vehicle (e.g., an unmanned vehicle), or the like, on which the image capturing device is mounted.

Fig. 1 is a schematic structural diagram of an apparatus control system according to an embodiment of the present disclosure. In fig. 1, the device control system may include a mobile platform 10, a control device 20, a display terminal 30, and the like, and the mobile platform 10, the control device 20, and the display terminal 30 may be wirelessly connected for communication, which will be described in detail below.

Wherein, movable platform 10 can include cloud platform and image acquisition equipment etc. and this cloud platform can be installed on movable platform's body, and this image acquisition equipment can carry on this cloud platform to alright the angle in order to adjust the cloud platform according to actual need, so that image acquisition equipment can follow a plurality of different angles and gather the image.

Taking movable platform 10 as aircraft 10 for example, aircraft 10 may include a drone, and this drone may include a rotor type drone (e.g., a single rotor drone, a dual rotor drone, a quad rotor drone, a hexarotor drone, or an octarotor drone, etc.), a fixed wing drone, or a combination of a rotor type and a fixed wing drone, without limitation herein. Referring to fig. 1, the device control system includes an aircraft 10, a manipulation device 20, and a display terminal 30. The aircraft 10 is equipped with an image capturing device, the aircraft 10 may be further connected with a control device 20, a display terminal 30, and the like, wherein the control device 20 may include one or more remote controllers for controlling the flight of the aircraft 10 or executing corresponding actions, and acquiring corresponding motion information from the aircraft 10, where the motion information may include flight direction, flight attitude, flight altitude, flight speed, position information, and the like, and at this time, the acquired motion information, an image captured by the image capturing device, and the like may be sent to the display terminal 30, and the display terminal 30 may perform analysis, display, and the like. The control device 20 may also be configured to control an image capturing device on the aircraft 10 to perform operations such as shooting or image transmission, and the control device 20 may also be configured to control a pan-tilt head on the aircraft 10 to perform operations such as angle adjustment. The flight information and the shooting instruction of the aircraft 10 are not limited to be controlled by the control device, and in other possible scenarios, the display terminal 30 may also be used to directly control the flight of the aircraft 10 or perform corresponding actions without the control device 20, and control the image capturing device on the aircraft 10 to perform shooting or image transmission and other operations.

The aircraft 10 may also be configured to close a shutter of the image acquisition device, encode an image acquired by the image acquisition device before the shutter is closed and a preset identifier for indicating that the shutter of the image acquisition device is closed, generate a code stream, store the code stream, and the like. Alternatively, the aircraft 10 may be further configured to close a shutter of the image capturing device, and generate and store caption information corresponding to an image captured by the image capturing device, where the caption information includes a preset identifier, where the preset identifier is used to indicate that the shutter of the image capturing device is closed. Alternatively, the aircraft 10 may also transmit first indication information indicating that the shutter of the image capturing device is closed to the display terminal 30 after closing the shutter of the image capturing device.

The display terminal 30 may include a laptop, a tablet computer, or a mobile phone, and may be configured to receive an image (i.e., a picture) captured by the image capturing device sent by the aircraft 10 and display the image in a display screen. The display terminal 30 may also receive control instructions input by a user, and accordingly control the image capturing device on the aircraft 10 based on the control instructions. For example, the display terminal 30 may receive a shooting instruction and transmit the shooting instruction to the aircraft 10, and the aircraft 10 may control the image capturing apparatus to capture a captured picture according to the shooting instruction, and the like. The display terminal 30 may further receive a code stream sent by the aircraft 10 through the image acquisition device, and display an image containing a preset identifier obtained based on decoding of the code stream, so as to know that a shutter of the image acquisition device is closed based on the preset identifier. Or, the display terminal 30 may further receive, during displaying the image captured by the image capturing device, subtitle information containing a preset identifier sent by the aircraft 10 through the image capturing device, and display the subtitle information, so as to know that the shutter of the image capturing device is closed based on the subtitle information containing the preset identifier. Alternatively, the display terminal 30 may further receive first indication information sent by the aircraft 10 through the image capturing device, and output a warning message based on the first indication information, so that the user knows that the shutter of the image capturing device is closed based on the warning message.

As shown in fig. 2, taking an image capturing device as an infrared camera as an example, the infrared camera may include an infrared lens 40, an infrared temperature control module 50, a codec module 60, a storage module 70, a transceiver module 80, and the like, where the infrared lens 40 may send a captured image to the codec module 60, the infrared temperature control module 50 may monitor a temperature of a cavity of the infrared lens 40, and send a shutter closing message to the infrared lens 40 when the temperature exceeds a preset threshold (which may be flexibly set according to actual needs), so that the infrared lens 40 performs a shutter closing operation, and the infrared temperature control module 50 may send a message to the codec module 60 to inform the codec module 60 that the shutter is about to close, at this time, the codec module 60 may encode a last frame image sent by the infrared lens 40 with a preset identifier (such as a tag or a watermark) for indicating that the shutter of the infrared camera is closed, and generating a code stream and sending the code stream to the storage module 70 for storage. When the infrared temperature control module 50 monitors that the shutter of the infrared lens 40 is closed, it may notify the encoding and decoding module 60 that the shutter is closed, at this time, the encoding and decoding module 60 cancels the encoding of the preset identifier, only encodes the image sent by the infrared lens 40, generates the current code stream, and sends the current code stream to the storage module 70 for storage. Or, after the shutter is closed, the codec module 60 may directly encode the image without changing the encoding information, and at this time, the codec module 60 may generate subtitle information including a preset identifier for indicating that the shutter of the infrared camera is closed, and send the subtitle information to the storage module 70 for storage.

The transceiver module 80 may establish a connection with the display terminal 30, and after the storage module 70 stores the code stream or the subtitle information, the transceiver module 80 may obtain the code stream or the subtitle information from the storage module 70 according to actual needs, and send the code stream or the subtitle information to the display terminal 30, and the subsequent display terminal may store the code stream or the subtitle information, or display a through image or subtitle information corresponding to the code stream, and the like.

For example, if the user needs to review the images captured by the infrared camera, the display terminal 30 may download the corresponding code stream from the storage module 70 (e.g., an SD card or a memory card) and include the caption information such as the capturing time or the geographic location information, and then display the downloaded images corresponding to the code stream and display the caption information, so as to inform the user of the information such as the capturing time or the geographic location information in time for the scenes viewed by the user. For another example, the display terminal 30 may play an image corresponding to the code stream sent by the transceiver module 80 in real time, and at this time, for the scene played in real time, since the user actually knows the subtitle information (current shooting time or geographical location information, etc.), the transceiver module 80 may not need to transmit the subtitle information to the display terminal 30.

For another example, as shown in fig. 3, when detecting that the temperature of the cavity of the infrared lens 40 exceeds the preset threshold, the infrared temperature control module 50 sends first indication information indicating that the shutter of the infrared camera is closed to the application APP on the display terminal 30, so that the APP can pop up to display a reminder that the shutter of the infrared camera is closed. When the shutter is closed, the infrared temperature control module 50 may send second indication information indicating that the shutter of the infrared camera is opened to the application APP on the display terminal, so that the APP may close the reminding information displayed by the pop-up window.

It should be noted that the device structures in fig. 1 to 3 do not constitute a limitation to an application scenario of the device control method.

Referring to fig. 4, fig. 4 is a schematic flowchart illustrating an apparatus control method according to an embodiment of the present disclosure. The device control method can be applied to image acquisition equipment with a shutter function, and is used for coding an image based on a preset identifier representing that a shutter of the image acquisition equipment is closed after the shutter is closed, so that the shutter can be known to be closed through the preset identifier.

As shown in fig. 4, the device control method may include steps S101 to S104, and the like, and specifically may be as follows:

and S101, controlling to close the shutter of the image acquisition equipment when a preset shutter closing triggering condition is met.

In some embodiments, the image capture device may be an infrared camera, an ultraviolet camera, or the like having a shutter function. In order to improve the flexibility of the image acquisition equipment in use, the image acquisition equipment can open a shutter to acquire images and close the shutter to suspend image acquisition according to actual needs.

The preset shutter closing triggering condition can be flexibly set according to actual needs, and specific contents are not limited here.

In some embodiments, when the preset shutter-closing trigger condition is satisfied, before controlling to close the shutter of the image capturing apparatus, the apparatus control method may further include: when the image acquisition equipment is started, detecting the initial temperature of a preset position of the image acquisition equipment; detecting the current temperature of a preset position of the image acquisition equipment in the using process of the image acquisition equipment; and if the difference value between the initial temperature and the current temperature is greater than a preset threshold value, determining that a preset shutter closing triggering condition is met.

In order to improve the accuracy of the preset shutter closing triggering condition determination, whether the preset shutter closing triggering condition is met or not can be determined by detecting the initial temperature and the current temperature of the preset position of the image acquisition device. Specifically, when the image capturing device is turned on, the initial temperature of the preset position of the image capturing device may be detected. In the using process of the image acquisition device, the current temperature of the preset position of the image acquisition device is detected in real time or at preset time intervals, for example, the initial temperature and the current temperature of the preset position are detected by an infrared sensor of the image acquisition device based on the acquired image, or the initial temperature and the current temperature of the preset position are detected by a temperature sensor preset by the image acquisition device, and the like, wherein the preset time can be flexibly set according to actual needs, for example, the preset time can be set to 5 minutes and the like.

In order to improve the reliability of the temperature detection, in some embodiments, the preset position may be a cavity of a lens of the image acquisition device. In the working process of the image acquisition equipment, the cavity of the lens of the image acquisition equipment converges heat, so that the acquired data (such as observation and temperature measurement) of the image acquisition equipment is influenced, and therefore, in order to avoid the problem that the cavity of the lens of the image acquisition equipment is too high, so that the accuracy of temperature measurement of an external scene is influenced, whether the preset shutter-closing triggering condition is met or not can be judged by detecting the initial temperature and the current temperature of the cavity of the lens of the image acquisition equipment.

After the initial temperature and the current temperature are obtained, the initial temperature and the current temperature may be compared, for example, a difference between the initial temperature and the current temperature may be calculated, and it is determined that the difference between the initial temperature and the current temperature is greater than a preset threshold, for example, it is determined whether the temperature of the current temperature relative to the initial temperature exceeds the preset threshold, where the preset threshold may be flexibly set according to actual needs.

If the difference between the initial temperature and the current temperature is smaller than or equal to the preset threshold, the current temperature of the image acquisition equipment is maintained in a normal range, and at this time, it can be determined that the preset shutter closing triggering condition is not met, and the state of opening the shutter is maintained. If the difference value between the initial temperature and the current temperature is greater than the preset threshold value, the current temperature of the image acquisition equipment is higher, and in order to avoid the influence of the overhigh temperature of the image acquisition equipment on the accuracy of temperature measurement of an external scene, the preset shutter closing triggering condition can be determined to be met so as to close the shutter of the image acquisition equipment, so that the convenience of controlling the image acquisition equipment is improved, and the accuracy of temperature measurement is improved.

In some embodiments, when the preset shutter-closing trigger condition is satisfied, before controlling to close the shutter of the image capturing apparatus, the apparatus control method may further include: detecting the current temperature of a preset position of the image acquisition equipment; and if the current temperature is greater than the preset temperature threshold value, determining that the preset shutter closing triggering condition is met.

In order to improve the convenience of judging the preset shutter closing triggering condition, whether the preset shutter closing triggering condition is met or not can be judged by detecting the current temperature of the preset position of the image acquisition equipment. Specifically, in the using process of the image capturing device, the current temperature of the preset position of the image capturing device may be detected in real time or at preset time intervals by using a temperature sensor or a temperature detector preset at the preset position of the image capturing device, wherein the preset time may be flexibly set according to actual needs, for example, the preset time may be set to 5 minutes, and the like. In order to improve the reliability of the temperature detection, the preset position may be a cavity of a lens of the image acquisition device. In the working process of the image acquisition equipment, the cavity of the lens of the image acquisition equipment converges heat, so that the acquired data of the image acquisition equipment is influenced, and therefore, in order to avoid overhigh cavity of the lens of the image acquisition equipment, whether the preset shutter-closing triggering condition is met or not can be judged by detecting the current temperature of the cavity of the lens of the image acquisition equipment.

After the current temperature is obtained, it can be judged that the current temperature is greater than a preset temperature threshold, wherein the preset temperature threshold can be flexibly set according to actual needs. If the current temperature is less than or equal to the preset temperature threshold, the current temperature of the image acquisition equipment is maintained in a normal range, and at this time, it can be determined that the preset shutter closing triggering condition is not met, and the state of opening the shutter is maintained. If the current temperature is higher than the preset temperature threshold, the current temperature of the image acquisition device is high, and in order to avoid that the normal operation is influenced due to the overhigh temperature of the image acquisition device, the preset shutter closing triggering condition can be determined to be met so as to close the shutter of the image acquisition device.

In some embodiments, when the preset shutter-closing trigger condition is satisfied, before controlling to close the shutter of the image capturing apparatus, the apparatus control method may further include: detecting whether a shutter closing key preset by the image acquisition equipment has triggering operation or not; and if the preset shutter closing key of the image acquisition equipment has triggering operation, determining that the preset shutter closing triggering condition is met.

In order to improve the accuracy of judging the preset shutter closing triggering condition, whether the preset shutter closing triggering condition is met or not can be judged by detecting the triggering of a shutter closing button preset by the image acquisition equipment. Specifically, the image capturing device may be preset with a shutter closing key, and the setting position, type, material, size, color, and the like of the shutter closing key may be flexibly set according to actual needs, and the specific content is not limited here. For example, the shutter close key may be a virtual key or a physical key, etc.

In the using process of the image acquisition equipment, whether the trigger operation exists on the shutter closing key at the preset position of the image acquisition equipment can be detected in real time or at preset time intervals, wherein the preset time can be flexibly set according to actual needs, for example, the preset time can be set to 0.1 second or 0.05 second and the like. The trigger operation may include a pressing operation or a clicking operation, for example, when the force of pressing the shutter closing key is greater than a preset pressure threshold, it is determined that the shutter closing key has the trigger operation; or when the time for pressing the shutter closing key reaches a preset time value, determining that the trigger operation exists on the shutter closing key; or when the pressing force of the shutter closing key is greater than a preset pressure threshold value and the pressing time of the shutter closing key reaches a preset time value, determining that the trigger operation exists on the shutter closing key; and the like, wherein the preset pressure threshold value and the preset time value can be flexibly set according to actual needs.

If the shutter closing key preset by the image acquisition equipment has no triggering operation, determining that the preset shutter closing triggering condition is not met; if the trigger operation exists on the shutter closing key preset by the image acquisition equipment, the preset shutter closing trigger condition is determined to be met so as to close the shutter of the image acquisition equipment, and therefore a user can conveniently and timely close the shutter manually according to actual requirements.

It should be noted that a shutter closing key may also be provided on the control device for controlling the image capturing device, and when there is a trigger operation on the shutter closing key on the control device, the image capturing device may receive a shutter closing instruction sent by the control device, and close the shutter based on the shutter closing instruction.

In some embodiments, when the preset shutter-closing trigger condition is satisfied, before controlling to close the shutter of the image capturing apparatus, the apparatus control method may further include: detecting the starting time of the image acquisition equipment; and when the time reaches a preset time threshold value, determining that a preset shutter closing triggering condition is met.

In order to improve the flexibility of the preset close shutter trigger condition determination, whether the preset close shutter trigger condition is satisfied may be determined by detecting the time when the image capturing apparatus is turned on. Specifically, as the image capturing device is used for a longer time, the more the heat is gathered, and the temperature is higher, when the image capturing device starts to be started, a preset timer can be started to start timing, and when the timing reaches a preset time threshold, it is indicated that the image capturing device has been used for a longer time, so that the current temperature of the image capturing device may be higher, and at this time, it can be determined that a preset shutter closing triggering condition is met, so as to close the shutter of the image capturing device.

S102, acquiring an image acquired by the image acquisition equipment before the shutter is closed.

Since the image capturing device can capture an image normally before the shutter is closed, an image captured by the image capturing device before the shutter is closed can be obtained, the image may include one or more frames, and the image may be a penultimate image and/or a penultimate image captured by the image capturing device before the shutter is closed.

To improve the accuracy and timeliness of identifying that the shutter is closed, in some embodiments, the image may be the last frame of image captured by the image capture device before the shutter is closed. So that the last frame of image captured by the image capture device before the shutter is closed and the preset identification can be used for encoding to indicate that the shutter of the image capture device is closed.

S103, coding is carried out by adopting the image and a preset identifier to generate a code stream, wherein the preset identifier is used for representing that a shutter of the image acquisition equipment is closed.

After the image is obtained, the image and the preset identifier may be used for encoding to generate a code stream, for example, the last frame of image collected by the image collection device before the shutter is closed and the preset identifier may be used for encoding to generate a code stream containing the preset identifier. The preset identifier may be flexibly set according to actual needs, for example, the preset identifier may include a label or a watermark for representing that a shutter of the image capturing device is closed, and the preset identifier may be composed of letters, characters, and/or icons, and the specific content is not limited here.

It should be noted that a timestamp corresponding to the last frame of image acquired by the image acquisition device before the shutter is closed may also be acquired, and the image is encoded according to the timestamp and the preset identifier to generate a code stream, so that the image may be accurately displayed according to the timestamp in the following.

In some embodiments, the encoding is performed by using an image and a preset identifier, and generating the code stream may include: and coding the image and the label or the watermark representing the closed shutter of the image acquisition equipment by adopting an intra-frame coding or inter-frame coding mode to generate a code stream.

In order to improve the convenience and efficiency of encoding, the last frame of image acquired by the image acquisition equipment before the shutter is closed and the label or watermark representing that the shutter of the image acquisition equipment is closed can be adopted to encode through an intra-frame encoding mode or an inter-frame encoding mode, and a code stream containing the label or the watermark is generated. Of course, other encoding schemes may be used. Accordingly, in the subsequent decoding, the code stream may be decoded by a decoding method corresponding to the encoding method.

And S104, storing or transmitting the code stream.

After the code stream is obtained, the code stream may be stored in a local database of the image acquisition device, or the code stream may be sent to a server for storage, and the like. And the code stream can be sent to the display terminal, so that the display terminal stores the code stream, or the code stream is decoded to obtain an image containing the preset identifier, and the image containing the preset identifier is displayed. Therefore, an interface representing that the shutter of the image acquisition equipment is closed can be presented to a user, the shutter is clearly prompted to be closed, and the current image acquisition equipment cannot be mistakenly judged to be blocked or lose frames and the like.

In an application scene, after the image acquisition equipment works for a period of time, the lens and the cavity converge heat, so that the observation and temperature measurement of the image acquisition equipment are influenced, at the moment, the image acquisition equipment can take the measures of closing a shutter, calculating the temperature in the cavity and the like, and the subsequent temperature measurement, observation and the like can remove the influence of the part, so that the accurate temperature measurement, observation and other operations of the image acquisition equipment are realized. During the shutter is closed, the image acquisition equipment cannot acquire images, at the moment, the images acquired by the image acquisition equipment are frozen, the phenomenon of blocking or video frame loss is caused, and particularly, when the videos of the image acquisition equipment are checked in the later period, the code stream is easily mistaken to be problematic. Therefore, according to the embodiment of the application, after the shutter of the image acquisition device is closed, the last frame of image acquired by the image acquisition device before the shutter is closed can be acquired, then the last frame of image and the preset identification used for representing the closed shutter of the image acquisition device are adopted for coding, and the code stream is generated, so that the closed shutter can be known through the preset identification, the phenomenon that the shutter is blocked or lost due to the fact that the code stream is mistakenly judged to be in a problem is avoided, and the convenience and flexibility of controlling the image acquisition device are improved.

In some embodiments, after storing or transmitting the codestream, the device control method may further include: and when the shutter is closed, opening the shutter, collecting the current image, coding the current image, generating a current code stream, and storing or transmitting the current code stream.

In order to improve the accuracy of indicating the shutter state, the preset identifier can be cancelled in time after the shutter is opened, specifically, the image acquisition device can monitor whether the shutter is closed or not, and when the shutter is not closed, the last frame of image acquired by the image acquisition device and the preset identifier used for representing the closed shutter of the image acquisition device can be continuously adopted for encoding to generate a code stream; when the shutter is closed, the shutter of the image acquisition device is opened at the moment, the image acquisition device can acquire a current image, then the current image can be encoded through an intra-frame encoding mode or an inter-frame encoding mode and other encoding modes to generate a current code stream, the current code stream does not contain a preset identifier, and at the moment, the current code stream can be stored in a local database of the image acquisition device or sent to a server for storage and the like. And/or, the current code stream may be sent to the display terminal, so that the display terminal stores the current code stream, or the current code stream is decoded to obtain an image, and the image is displayed.

For example, in the using process of the image acquisition device, the image acquisition device acquires 60 frames of images, closes the shutter when acquiring the 60 th frame of images, and then can perform encoding by using the 60 th frame of images and a preset identifier for representing that the shutter of the image acquisition device is closed, so as to generate a code stream. At this time, during the period (for example, within 1 minute) that the shutter is closed, the image capturing device does not capture an image, that is, no new image is captured, so the image capturing device may encode the image of the 60 th frame and the preset identifier for representing that the shutter of the image capturing device is closed, and generate the code stream until the shutter is opened. When the shutter is opened, the image acquisition device can acquire the 61 st frame image, the 61 st frame image is not required to be encoded by using a preset identifier, but the 61 st frame image is directly encoded to generate a current code stream, the current code stream does not contain the preset identifier, and the current code stream can be stored or sent at the moment.

In some embodiments, when the closing of the shutter ends, before the opening of the shutter, the device control method may further include: acquiring the time period of shutter closing; judging whether the closing end time of the shutter reaches according to the time period; when the end time of shutter closing is reached, it is determined that shutter closing is ended.

Specifically, the shutter closing time period may be acquired, and the shutter closing time period may be flexibly set according to actual needs, for example, the shutter closing time period set by a user may be received, or the shutter closing time period may be set by default by the system. For another example, the target temperature at the preset position when the image acquisition device acquires the last frame of image before the shutter is closed may be obtained, then, the target temperature decrease range in which the target temperature decreases to the preset temperature value may be determined, the mapping relationship between the preset temperature decrease range and the required time may be obtained, the required time corresponding to the target temperature decrease range may be determined according to the mapping relationship, and the time period for closing the shutter may be obtained.

After the time period of shutter closing is obtained, the end time of shutter closing can be determined according to the time period of shutter closing, when the shutter starts to close, a preset timer can be started to start timing, and when the timing reaches the end time of shutter closing, the end of shutter closing is determined.

In some embodiments, when the closing of the shutter ends, before the opening of the shutter, the device control method may further include: detecting whether a shutter opening key preset by the image acquisition equipment has trigger operation or not; and if the shutter opening key preset by the image acquisition equipment has triggering operation, determining that the shutter is closed.

Specifically, the image capturing device may be preset with a shutter opening button, and the setting position, type, material, size, color, and the like of the shutter opening button may be flexibly set according to actual needs, and the specific content is not limited here. For example, the shutter open key may be a virtual key or a physical key, etc. The shutter opening key and the shutter closing key can be the same key or two independent keys, and the like. When the shutter opening key and the shutter closing key can be the same key, in the shutter opening state, when the key is triggered, the shutter is closed; when the button is triggered in the shutter closed state, the shutter is opened.

After the shutter of the image acquisition equipment is closed, whether the trigger operation exists on the shutter opening key at the preset position of the image acquisition equipment can be detected in real time or at preset time intervals, wherein the preset time can be flexibly set according to actual needs. The trigger operation of the shutter opening key may be consistent or inconsistent with the trigger operation of the shutter closing key, and the trigger operation may include a pressing or clicking operation, for example, when the force with which the shutter opening key is pressed is greater than a preset pressure threshold, it is determined that the trigger operation of the shutter opening key exists; or when the time for pressing the shutter opening key reaches a preset time value, determining that the trigger operation exists on the shutter opening key; or when the pressing force of the shutter opening key is greater than a preset pressure threshold value and the pressing time of the shutter opening key reaches a preset time value, determining that the trigger operation exists on the shutter opening key; and the like, wherein the preset pressure threshold value and the preset time value can be flexibly set according to actual needs.

If the shutter opening key preset by the image acquisition equipment has no triggering operation, determining that the shutter closing is not finished; if the trigger operation exists on a shutter opening button preset by the image acquisition equipment, the closing of the shutter is determined to be finished so as to open the shutter of the image acquisition equipment, and therefore a user can conveniently and manually open the shutter according to actual requirements.
