Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import by those skilled in the art without departing from the spirit of this application and is therefore not limited to the specific implementations disclosed below.

In the present application, a method and an apparatus for acquiring image data, an intelligent device and a computer readable storage medium are provided, which are described in detail in the following embodiments one by one.

In an embodiment of the present application, the present application discloses a method for acquiring image data, referring to fig. 1, including:

101. and monitoring the inclination angle of the intelligent equipment in real time.

Referring to fig. 2, a rectangular coordinate system of the direction in which the smart device is located is shown in fig. 2. As can be seen from fig. 2, XY is horizontal, Z is vertical and upward, and in the static state of the smart device shown in fig. 2, the acceleration sensor reading in XY is 0, the acceleration sensor reading in Z is 1G, and G represents the value of the gravitational acceleration. In this embodiment, the tilt angle refers to an absolute value of an angle of the smart device deviating from the Z axis in the rectangular coordinate system.

In this embodiment, the real-time monitoring refers to monitoring the smart device uninterruptedly to obtain a parameter value of the smart device. Parameter values include, but are not limited to: the smart device deviates from the Z-axis by an angle value theta.

The smart device may be any type of mobile smart device, including a mobile computer or mobile computing device (e.g., tablet, personal digital assistant, laptop, notebook, netbook, etc.), a mobile phone, a wearable mobile device (e.g., smart watch, smart glasses, etc.), or other type of mobile device. In a specific embodiment of the present invention, the smart device is preferably provided with an inertial measurement unit, i.e. a gyroscope or a gravitational acceleration sensor.

Generally, the tilt angle of the smart device is monitored in real time by an inertial measurement unit in the smart device. Wherein, inertial measurement unit includes: a gyroscope and an acceleration sensor.

For a gyroscope, also called an angular velocity sensor, the angular velocity of the smart device can be directly obtained. If the angle value is to be obtained, the angle value is further integrated.

For the acceleration sensor, since the acceleration sensor is subjected to gravity when placed at rest, when the smart device is in the rest state shown in fig. 2, the acceleration sensor reading in the XY direction is 0, the acceleration sensor reading in the Z direction is 1G, and G represents the value of the gravity acceleration. If the smart device is rotated around the Y-axis, the readings of the acceleration sensors of the Y-axis are still 0, and the data of the acceleration sensors of the X-axis and the Z-axis are changed. By measuring the acceleration of the intelligent device in three axial directions and utilizing the property that the gravity acceleration is 1G (G represents the value of the gravity acceleration), the inclination angle of the intelligent device in the three-axis direction can be calculated.

In practical application, the inclination angle of the intelligent device in the three-axis direction can be indirectly obtained through the acceleration sensor, and the inclination angle of the intelligent device in the three-axis direction can also be obtained in a mode of combining the gyroscope and the acceleration sensor.

102. Under the condition that the inclination angle of the intelligent equipment is smaller than or equal to the first threshold value and meets the photographing condition, the first camera of the intelligent equipment is controlled to photograph to obtain photo data.

The first threshold may be set according to actual requirements, for example, set to 3 degrees, 5 degrees, 6 degrees, and so on. The inclination angle equal to or smaller than the first threshold value means an absolute value of the angle value θ deviating from the Z axis, and the positive or negative of the angle value θ deviating from the Z axis is not considered, that is, the absolute value of the angle value θ deviating from the Z axis is the inclination angle. The angle value θ may be positive, negative, and within [ -180 °, +180 ° ]. Then, the inclination angle of the intelligent device is in the range of 0 to the first threshold, and in the range, the intelligent device is in the vertical state, so that the use habit of the user is met.

The upright state refers to a state in which the rear camera of the smart device is directed forward and the screen of the smart device faces the user. Note that the standing state described here does not mean that the angle between the smart device and the Z axis is 0 degree, and the present invention is applicable to the standing state whether the smart device is in the horizontally standing state or the vertically standing state, or in the upright standing state or the inverted standing state. For example, the mobile phone shown in fig. 2 is in a vertical standing state, and for example, when a user plays a game or watches a movie with the mobile phone, the mobile phone is placed in a horizontal standing state.

In the embodiment of the application, the second camera is turned on in advance and keeps an on state. The first camera can be started in advance and kept in a starting state, and can also be started in response to the photographing instruction in the step.

If the first camera is started in advance and keeps the starting state, the power consumption is larger, but the picture can be captured in a rush at the first time. The first camera is turned on in response to the photographing instruction, so that the power consumption can be reduced, but the photographing is delayed. Therefore, a setting function is provided in practical application, and a user can set the opening mode of the first camera according to requirements.

In addition, in this embodiment, the photographing condition may be set in advance. In one embodiment of the present application, the photographing condition is that a photographing voice instruction is received by the voice receiving unit. During actual use, the built-in voice receiving unit (such as a microphone) of the intelligent device is started to receive the voice command in real time, and the intelligent device can receive the voice command in real time no matter the intelligent device is in a screen locking or unlocking state. The voice instruction satisfying the photographing condition may be preset, for example, a voice instruction of "photographing", and the like. And when the acquired voice is a preset voice instruction, the shooting condition is considered to be met.

In an embodiment of the present application, the photographing condition is that an image is acquired by the second camera. The images meeting the photographing condition may be preset, for example, the image collected by the second camera includes a portrait or the image collected by the second camera includes a landscape. If the black area is large in the image collected by the second camera, the scene is judged to be absent, and the condition that the photographing condition is not met is met. In an embodiment of the present invention, if the black area in the image is greater than 80%, and the black area is equal to or greater than a certain set maximum area threshold, it may be determined that the photographing condition is not satisfied.

In practical application, the second camera collects the portrait, so that the photographing condition is met, and the use condition during actual photographing is better met.

In an embodiment of the application, the photographing condition may be set to not only satisfy that the second camera acquires an image, but also satisfy that preset photographing mode information is detected. The preset photographing mode information may be a selection item in a setting menu. For example, a setting menu is provided with an option of 'triggering a photographing mode when a second camera is set to acquire an image', and if the option is selected, a photographing condition is met when the second camera acquires the image; if the option is not selected, even if the second camera collects images, the photographing condition is not met. In the embodiment, the presetting of the photographing mode information is added, so that the false triggering of the photographing action can be avoided.

In this embodiment, the first camera is a rear camera; the second camera is leading camera, the camera that opens when autodyne usually promptly.

Or 103, under the condition that the inclination angle of the intelligent device is smaller than or equal to a first threshold value and meets the shooting condition, controlling a first camera of the intelligent device to shoot to acquire video data.

It should be noted that

steps

102 and 103 are in parallel relationship and not executed sequentially, but at the same time, steps 102 and 103 can only be executed alternatively and not simultaneously. If only one of the

steps

102 or 103 exists, the technical solution of the present invention can still be completed.

The first threshold may be set according to actual requirements, for example, set to 3 degrees, 5 degrees, 6 degrees, and so on. The tilt angle is an absolute value of an angle of the smart device deviating from the Z axis in the rectangular coordinate system. The inclination angle is smaller than or equal to the first threshold value, which means that the inclination angle of the intelligent device is in the range of 0-the first threshold value. In the range of the inclination angle, the intelligent equipment is in a vertical state, and the use habit of a user is met.

In the embodiment of the application, the second camera is turned on in advance and keeps an on state.

In practical application, the first camera may be turned on in advance, or may be turned on in response to the camera shooting instruction in this step.

If the first camera is started in advance, the power consumption is larger, but the first time of shooting can be guaranteed. The first camera is turned on in response to a photographing or image pickup instruction, so that power consumption can be reduced, but image pickup delay is caused.

In one embodiment of the present application, the image capturing condition may be that an image capturing voice instruction is received by the voice receiving unit. During actual use, a voice receiving unit (such as a microphone) arranged in the intelligent device is started to receive a voice instruction in real time, and the intelligent device is in a screen locking or unlocking state. Voice instructions satisfying the imaging conditions may be preset, for example, voice instructions such as "image capture", "start of image capture", and the like. And when the acquired voice is a preset voice instruction, the camera shooting condition is considered to be met.

In an embodiment of the present application, the shooting condition may be that an image is captured by the second camera and a physical key shooting instruction is received. The images meeting the shooting condition can be preset, for example, the images collected by the second camera include a portrait or the images collected by the second camera include a landscape, and the second camera is preferably used for collecting the portrait and accords with the use situation during actual shooting. In addition, the physical key camera shooting instruction is an instruction for triggering physical key input, for example, the camera shooting instruction is input by pressing a side key of the intelligent device. In this embodiment, two conditions that the second camera acquires an image and receives a physical key camera shooting instruction need to be satisfied, so that false triggering of a camera shooting action can be avoided.

In an embodiment of the present application, the shooting condition may be that not only the second camera needs to acquire an image, but also preset shooting mode information needs to be detected. The preset image capture mode information is, for example, a selection item in a setting menu. For example, setting an option of 'setting the second camera to acquire the image as the trigger shooting mode' in the menu, and if the option is selected, meeting shooting conditions when the second camera acquires the image; if the option is not selected, the shooting condition is not met even if the second camera collects images. In this embodiment, two preset conditions of the second camera acquiring the image and the shooting mode information need to be satisfied, so that false triggering of the shooting action is avoided.

104. And storing the photo data or the video data in a designated storage space.

The storage space is a cache or a hard disk of the intelligent device.

In this way, if the user needs to view the photo data or the video data, the viewing can be invoked in the designated storage space.

According to the method for acquiring the image data, the inclination angle of the intelligent device is monitored in real time, and when a certain photographing condition or a certain photographing condition is met, the first camera of the intelligent device is controlled to photograph or pick up, so that the process that in the prior art, a screen of the intelligent device is opened, a camera program is started, and an external instruction is received is avoided, the operation is simple and convenient, the time is saved, the response speed is increased, and the user experience degree is improved.
