Object recognition method and mobile terminal
An object identification method and a mobile terminal are provided. The object identification method includes: capturing a scan object through the camera in a first operating state, in a case that a screen of the mobile terminal is turned off, to obtain a first capturing result; controlling the camera to enter a second operating state in a case that the scan object is determined to meet a preset condition according to the first capturing result, capturing the scan object through the camera in the second operating state to obtain a second capturing result, recognizing the scan object according to the second capturing result, and controlling the mobile terminal to turn on the screen to display a recognition result corresponding to the scan object.
1. An object recognition method, applied to a mobile terminal with a camera, comprising:
capturing a scan object through the camera in a first operating state, in a case that a screen of the mobile terminal is turned off, to obtain a first capturing result;
controlling the camera to enter a second operating state in a case that the scan object is determined to meet a preset condition according to the first capturing result, capturing the scan object through the camera in the second operating state to obtain a second capturing result, recognizing the scan object according to the second capturing result, and controlling the mobile terminal to turn on the screen to display a recognition result corresponding to the scan object;
wherein an operating power of the camera in the second operating state is greater than an operating power of the camera in the first operating state;
wherein prior to the capturing the scan object through the camera in the first operating state in the case that the screen of the mobile terminal is turned off, the method further comprises:
turning on the camera, and controlling the camera to enter the first operating state;
wherein the turning on the camera comprises:
detecting a turning-off or a turning-on operation on the screen of the mobile terminal;
turning on the camera in response to turning off the screen of the mobile terminal;
the object recognition method further comprises:
turning off the camera in response to turning on the screen of the mobile terminal.
2. The method according to claim 1 , wherein the first operating state is a state in which a part of pixel units of the camera are in a turning-on state, and the second operating state is a state in which all pixel units of the camera are in a turning-on state.
3. The method according to claim 1 , wherein the controlling the camera to enter the second operating state in the case that the scan object is determined to meet the preset condition according to the first capturing result comprises:
recognizing, through the camera, a characteristic of the scan object according to the first capturing result;
in a case that that the camera determines that the characteristic of the scan object matches a preset characteristic, controlling the camera to enter the second operating state.
4. A mobile terminal with a camera, comprising: a memory, a processor and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to:
capture a scan object through the camera in a first operating state in a case that a screen of the mobile terminal is turned off, to obtain a first capturing result;
control the camera to enter a second operating state in a case that the scan object is determined to meet a preset condition according to the first capturing result, capture the scan object through the camera in the second operating state to obtain a second capturing result, recognize the scan object according to the second capturing result, and control the mobile terminal to turn on the screen to display a recognition result corresponding to the scan object;
wherein an operating power of the camera in the second operating state is greater than an operating power of the camera in the first operating state;
wherein the processor executes the computer program to:
turn on the camera and control the camera to enter the first operating state;
wherein the processor executes the computer program to:
detect a turning-off or a turning-on operation on the screen of the mobile terminal;
turn on the camera in response to turning off the screen of the mobile terminal;
wherein the processor executes the computer program to:
turn off the camera in to turning on the screen of the mobile terminal.
5. The mobile terminal according to claim 4 , wherein the first operating state is a state in which a part of pixel units of the camera are in a turning-on state, and the second operating state is a state in which all pixel units of the camera are in a turning-on state.
6. The mobile terminal according to claim 4 , wherein the processor executes the computer program to:
recognize, through the camera, a characteristic of the scan object according to the first capturing result;
in a case that that the camera determines that the characteristic of the scan object matches a preset characteristic, control the camera to enter the second operating state.
7. A non-transitory computer-readable storage medium, wherein a computer program is stored in the computer-readable storage medium, a processor executes the computer program to perform the object recognition method according to claim 1 .
