Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings.
Example one
The embodiment of the invention provides an image acquisition control method of an intelligent terminal. The method can be executed by an image acquisition control device of the intelligent terminal, the device can be realized by software and/or hardware, and the device can be generally integrated in the intelligent terminal. Fig. 1 is a schematic flowchart of an image acquisition control method of an intelligent terminal according to an embodiment of the present invention, and as shown in fig. 1, the method includes:
s101, acquiring shooting direction information of a camera of the intelligent terminal in the current detection period.
In this embodiment, the shooting direction information of the intelligent terminal camera in the current detection period may be obtained according to the detection information reported by the angle detection device such as a gyroscope in the intelligent terminal. Wherein, the shooting direction information of camera can be for the camera place plane towards the perpendicular line of scenery side direction and the angle information of vertical downward direction, the perpendicular line and the contained angle information of vertical direction on camera place plane and the information of flat shot or bowing of shooting promptly.
For example, the detection information reported by the angle detection device may be shooting direction information of a camera or related information of the shooting direction of the camera, that is, the angle detection device may directly detect the shooting direction information of the camera or detect related information of the shooting direction of the camera, and accordingly, when the detection information reported by the angle detection device in the current detection period is the shooting direction information of the camera, the intelligent terminal may directly obtain the detection information reported by the angle detection device in the current detection period as the shooting direction information of the camera of the intelligent terminal in the current detection period; when the detection information reported by the detection device is related to the shooting direction of the camera, the intelligent terminal may perform corresponding operation using the detection information reported by the detection device as an argument to obtain the shooting direction information of the camera of the intelligent terminal in the current detection period, which is not limited herein. The intelligent terminal can acquire the shooting direction information of the camera in the current detection period at the beginning, middle and end of the current detection period or at other moments of the current detection period; the length of the detection period and the period length of the detection information reported by the angle detection device can be the same or different, and can be set by a user or a developer according to needs, for example, the default length of the detection period can be preset by an openers, and the user is allowed to adjust the length of the detection period according to needs; correspondingly, if the user does not set the detection period length, the shooting direction information of the intelligent terminal camera is obtained according to the default detection period length set by the developer.
Because the intelligent terminal is generally provided with a gyroscope for detecting the rotation angle of the intelligent terminal, considering the simplicity of the intelligent terminal, it is preferable that the rotation angle information of the mobile terminal detected by the gyroscope be directly used as the detection information reported by the angle detection device, and correspondingly, the intelligent terminal can determine the shooting direction information of the camera of the intelligent terminal in the current detection period according to the rotation angle information. For example, if the intelligent terminal is horizontally placed in the current detection period and the screen of the intelligent terminal faces vertically upwards, if the current camera started by the intelligent terminal is a rear camera with a plane parallel to the plane of the screen of the intelligent terminal, it can be determined that the shooting direction information of the camera of the intelligent terminal in the current detection period is a downward shooting and the included angle between the vertical line of the plane of the camera and the vertical direction is 0 degree; if the camera that intelligent terminal opened at present is the leading camera that the plane of place and intelligent terminal screen place plane are parallel, then can confirm that the shooting direction information of current detection cycle intelligent terminal's camera is for facing upward the bat and the camera place on the plane the perpendicular line and the contained angle of vertical direction be 0.

The set angle threshold may be set by a user or a developer as needed, for example, the developer may set a default angle threshold of the intelligent terminal, and the user may adjust the angle threshold according to his own scanning or photographing requirement. In consideration of the accuracy of the determined image acquisition mode of the intelligent terminal, the range of the set angle threshold is preferably 0-40 °, for example, the set angle threshold may be set to 30 °, and at this time, if the camera performs downward shooting and an included angle between a perpendicular line of a plane where the camera is located and the vertical direction is less than or equal to 30 °, the image acquisition mode of the intelligent terminal in the current detection period is determined to be a scanning mode.
S103, if the image acquisition mode of the current detection period is different from the image acquisition mode of the previous detection period and the image acquisition mode of the current detection period is a question scanning mode, starting a benchmarking function and an image recognition function of the intelligent terminal; and if the image acquisition mode of the current detection period is different from the image acquisition mode of the last detection period and the image acquisition mode of the current detection period is a shooting mode, closing the benchmarking function and the image recognition function of the intelligent terminal.
In this embodiment, when the image acquisition mode of the terminal device is changed from the shooting mode to the scanning mode, the benchmarking function of the intelligent terminal may be turned on to determine the area to be identified within the acquisition range of the camera, and the image identification function of the intelligent terminal may be turned on to identify the text and/or the graphics at the corresponding position of the area to be identified or the area to be identified within the screen; when the image acquisition mode of the terminal equipment is changed from the question scanning mode to the shooting mode, the benchmarking function and the image recognition function of the intelligent terminal can be closed, and in addition, the beautifying function of the intelligent terminal can be opened to process shot pictures.
