Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The following exemplary described embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure as recited in the claims below.
In order to solve the above technical problem, an embodiment of the present disclosure provides a camera control method, and fig. 1 is a flowchart of a camera control method shown according to an exemplary embodiment, and is applicable to an electronic device, where the electronic device may include a smart phone, a tablet computer, a personal computer, and other devices, the camera device may include a monitoring camera or a distributed camera, and the camera device includes a cradle head, and an effect of adjusting a view angle of the camera is achieved by controlling the cradle head to rotate left, right, up, or down.
Referring to fig. 1, a camera control method includes steps 11 to 13, where:
in step 11, a first preview image captured by a camera of an imaging device is acquired.
In this embodiment, the electronic device may establish a communication connection with the image capturing device, where the communication connection may include an end-to-end connection between the electronic device and the image capturing device, and the end-to-end connection mode includes at least one of the following: bluetooth connection, WiFi connection, infrared data transmission connection, ZigBee connection and ultra wide band connection, and the effect is as shown in figure 2. Referring to fig. 2, the electronic apparatus 10 may be connected with the image pickup apparatus 20 by end-to-end. In an example, the communication connection may further include the electronic device connecting with the image capturing device through a server, and the effect is as shown in fig. 3. Referring to fig. 3, the electronic apparatus 10 is connected to the image pickup apparatus through the server 30.
In this embodiment, after the communication connection is established, the electronic device may obtain a real-time image acquired by a camera of the image pickup device, which is hereinafter referred to as a first preview image. In this way, the first preview image can be displayed in the display interface of the electronic device.
In step 12, when the first preview image is acquired, acquiring a spatial attitude change of the electronic device to obtain spatial attitude offset data.
In this embodiment, when the first preview image is acquired, the electronic device may acquire a spatial posture of the electronic device at the current time, which is referred to as an initial spatial posture hereinafter. The initial spatial attitude may be obtained by a spatial attitude sensor built in the electronic device, such as at least one of a gravity sensor, an acceleration sensor, and a gyroscope.
In an example, the electronic device may acquire angle information of the electronic device as spatial attitude data through a built-in gravity sensor. Taking the example that the electronic device is a mobile phone, the angle information of the mobile phone obtained by the gravity sensor built in the mobile phone is as follows: the tilt angle with respect to the X-axis and/or the Y-axis in the plane XOY in which the display screen lies.
The plane XOY on which the display screen is located is a coordinate system plane formed by taking any point on the display screen as a coordinate origin O, taking the direction of the height as a Y axis, and taking the direction of the width as an X axis.
In another example, the electronic device may acquire spatial pose data through a built-in acceleration sensor. Taking the electronic device as an example of a mobile phone, when the mobile phone is placed horizontally, an acceleration sensor built in the mobile phone detects an inclination angle of the mobile phone with respect to an X axis and/or a Y axis in a plane XOY where a display screen is located.
In another example, the electronic device may obtain the tilt angle information through a built-in gyroscope, and determine the spatial attitude of the electronic device according to the tilt angle information. Taking the electronic device as an example of a mobile phone, a gyroscope built in the mobile phone detects an inclination angle of the mobile phone with respect to an X axis and/or a Y axis in a plane XOY where a display screen is located and an inclination angle with respect to a Z axis in the plane XOY where the display screen is located. Wherein the Z-axis is perpendicular to the XOY plane.
It should be noted that, considering that the cloud platform in the camera can rotate left or right around the Y axis, or rotate up or down around the X axis, in this embodiment, only the tilt angles with respect to the X axis and the Y axis are required to be acquired.
After determining the initial spatial attitude, the electronic device may continue to communicate with the attitude sensor to obtain spatial attitude data. And when the difference value of the two adjacent spatial attitude data is not zero, determining that the attitude of the electronic equipment is detected to be changed. When the change of the attitude of the electronic equipment is detected, the relative change of the electronic equipment relative to the initial space attitude is obtained, and space attitude offset data is obtained. For example, when the user holds the mobile phone and rotates the mobile phone 5 degrees to the left, the mobile phone may determine that the display screen rotates 5 degrees to the left around the Y axis, and the spatial attitude offset data is: x, -5 degrees.
In step 13, the spatial attitude offset data is sent to the image pickup apparatus, so that the image pickup apparatus adjusts the view angle of the camera thereof with a corresponding spatial attitude change according to the spatial attitude offset data.
In this embodiment, the electronic device may send the spatial attitude offset data to the image capturing device, and the sending method may include:
in one example, referring to fig. 4, in step 41, the electronic device may acquire a communication connection between the electronic device and the image capturing device, where the communication connection includes an end-to-end connection between the electronic device and the image capturing device, and the end-to-end connection includes at least one of: bluetooth connection, WiFi connection, infrared data transmission connection, ZigBee connection and ultra-wideband connection. In step 42, the electronic device may send spatial pose offset data to the camera device over the end-to-end connection. In this way, the electronic device can realize close-range control of the view angle of the camera in the image pickup device.
In another example, referring to fig. 5, in step 51, the electronic device may acquire a communication connection between the electronic device and the image capturing device, which may include the electronic device connecting with the image capturing device through a server. In step 52, the electronic device may send the spatial pose offset data to the server for the server to forward to the camera device.
It should be noted that the electronic device may be connected to the image capturing device through the end-to-end connection and the server at the same time, and in this case, the electronic device may randomly select, or select a communication connection with a larger bandwidth, or a communication connection with a better network signal for transmission, which is not limited herein.
In this embodiment, after the image capturing apparatus receives the spatial attitude offset data, the orientation of the camera thereof may be adjusted by the steering of the pan/tilt head, so as to adjust the viewing angle of the camera. Like this, can adjust the angle of framing of camera through the space gesture of adjustment electronic equipment in this embodiment, make camera and electronic equipment synchronous adjustment, operate more convenient and fast. Further analysis, this embodiment can reach the effect that similar user directly rotated the camera with the hand, and the adjustment is experienced like on-the-spot adjustment, is favorable to promoting to use and experiences.
Considering that the rotating electronic device is only a directional adjustment, in an embodiment, referring to fig. 6, in step 61, the electronic device may set a ruler covering layer in the display interface of the electronic device, and the effect is as shown in fig. 7. Referring to fig. 7, the scale covering layer includes a cross-shaped scale having an initial center point a located at the center of the display interface, and the cross-shaped scale rotates along with the rotation of the electronic device. In practical applications, the minimum resolution angle T of the cross scale may be set according to a specific scene, for example, the minimum resolution angle is 1 degree. In step 62, the electronic device may obtain the offset position of the initial center point according to the spatial attitude offset data, that is, the final stop position when the initial center point rotates along with the electronic device or the real-time position corresponding to the time when the sensor collects the spatial attitude data. In step 63, the electronics can move the cross-shaped scale so that the initial center point is at the offset position, the effect being shown in FIG. 8. Referring to fig. 8, as the electronic device rotates left about the Y axis, the initial center point will move to the right. Therefore, in the embodiment, the rotation angle on the X axis and/or the Y axis can be conveniently determined by the user through the number of the scales (minimum resolution angles) by moving the scale, and the view angle of the camera can be controlled more accurately.
Considering that the pan-tilt head of the camera has a rotation range, for example, the left-right rotation range is [ 90, 90 ] degrees, and the up-down rotation range is [ 90, 90 ] degrees, that is, unlimited rotation cannot be realized. In an embodiment, referring to fig. 9, in step 91, the electronic device may acquire an actual image captured by a camera of the camera device, which is referred to as a second preview image. The second preview image is an image acquired by a camera of the electronic device after the electronic device sends the spatial attitude offset data to the camera device.
In step 92, the electronic device may obtain a similarity of the second preview image and the first preview image. It can be understood that, if the camera adjusts the view angle after receiving the spatial attitude offset data, actual images acquired at different view angles are different, that is, the first preview image and the second preview image are different. In this step, the electronic device may obtain the feature vectors of the first preview image and the second preview image by using a preset feature extraction algorithm, where the feature extraction algorithm may complete a trained deep learning algorithm, such as a neural network (e.g., a convolutional neural network), a blob detection algorithm (e.g., a method for detecting a gaussian operator (LOG), a method using a Hessian matrix (second order differential) of a pixel point and a determinant value thereof (DOH)), a corner detection algorithm (e.g., a Harris algorithm and a FAST algorithm), a binary string feature descriptor, and the like. After the feature vectors are obtained, cosine values, i.e., similarity, of the two feature vectors can be calculated by using a cosine formula. When the cosine value is larger, it is said that the two feature vectors are more similar, i.e., the first preview image and the second preview image are more similar to each other.
In step 92, a preset similarity threshold, such as 0.95, may be stored in the electronic device. The electronic device may compare the similarity obtained in step 91 to the similarity threshold described above. In step 93, when the similarity is smaller than the similarity threshold, it indicates that the view angle of the camera is changed; when the similarity exceeds the similarity threshold value, it is indicated that the view angle of the camera is not changed, that is, the camera does not rotate after receiving the spatial attitude offset data, and at this time, the electronic device can generate a prompt message representing that the camera rotates to a limit position. The prompting message may be "the camera has rotated to the leftmost side, please rotate to the right", or "the camera has rotated to the rightmost side, please rotate to the left". Like this, can make the user in time know the rotation state of camera through generating the suggestion message in this embodiment, avoid the user to suspect the camera and damage, communication connection disconnection scheduling problem, be favorable to promoting and use experience.
Considering that the camera needs to take a picture or record a video after being adjusted to the view angle of the user's heart instrument, the user may cause the camera to continue to adjust by operating the electronic device at this time. In an embodiment, a lock key may be preset in a display interface of the electronic device, when the lock key is turned off, the electronic device may normally send the spatial attitude offset data, and after the lock key is turned on, the electronic device stops sending the spatial attitude offset data. Therefore, the electronic equipment can not influence the view angle of the camera no matter how the electronic equipment rotates, so that a user can conveniently take a picture or record a video, and the use experience is improved.
