Embodiment 1

[0019] figure 1 It is a schematic flowchart of a method for determining a search target provided in Embodiment 1 of the present invention. The method is suitable for determining the search target in the subject when taking pictures and scanning questions. The method can be executed by a device for determining the search target. function in the smart terminal.

[0020] In this embodiment, the smart terminal specifically refers to electronic devices such as smartphones, tablet computers, smart bracelets, and smart watches that have the function of taking pictures and scanning questions. At the same time, the smart terminal is provided with a camera and a cursor light. When the smart terminal in this embodiment is a smart phone or a tablet computer, the camera is a rear camera, and the cursor light is set adjacent to the camera on the same horizontal line; when the smart terminal is a smart watch or a smart hand At the same time, the camera and the cursor light are adjacently a...

Embodiment 2

[0036] figure 2 It is a schematic flowchart of a method for determining a search target provided in Embodiment 2 of the present invention. The embodiment of the present invention is optimized on the basis of the above-mentioned embodiments. In this embodiment, the translation direction of the smart terminal relative to the initial projection area is determined, and further optimization is as follows: real-time capture of the translation direction of the smart terminal during the translation process image frame, and perform image synthesis with the captured image frame; obtain the composite image frame when the translation of the intelligent terminal stops, and determine the current projection area of ​​the cursor light in the composite image frame; according to the initial projection The relative position of the area and the current projection area in the synthesized image frame determines the movement trajectory of the intelligent terminal; and determines the translation dir...

Embodiment 3

[0078] image 3 It is a structural block diagram of an apparatus for determining a search target provided in Embodiment 3 of the present invention. The device is suitable for determining the search target in the subject when taking pictures and scanning questions. The device can be realized by software and / or hardware, and is generally integrated in an intelligent terminal configured with the function of taking pictures and scanning questions. Such as image 3 As shown, the device includes: an initial area determination module 31 , a translation direction determination module 32 and a first target determination module 33 .

[0079] Wherein, the initial area determination module 31 is used to determine the initial projection area of ​​the cursor light in the captured image frame after starting the scanning of the subject by taking pictures of the smart terminal;

[0080] A translation direction determination module 32, configured to determine the translation direction of the ...

Abstract

The invention discloses a search target determining method and device. The method comprises that after that shooting and question scanning of an intelligent terminal is started, an initial projection area of a cursor light in a captured image frame is determined; and if it is monitored that the intelligent terminal translates within set time, the translation direction of the intelligent terminal relative to the initial projection area is determined, and a search target corresponding to the translation direction is determined. Via the method, the search target in the shooting and question scanning process can be determined rapidly according to whether the intelligent terminal moves or not within set time; and compared with the prior art, the shooting and question scanning accuracy are ensured, the search target determining process during shooting and question scanning is simplified to large extent, the operation efficiency of shooting and question scanning is improved, and the application range of the shooting and question scanning function of the intelligent terminal is expanded effectively.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a method and device for determining a search target. Background technique [0002] Photo scanning is a learning-related functional application on the smart terminal. Users can use the camera on the smart terminal combined with the cursor light to realize the capture, positioning and related search of the content to be searched. Specifically, when taking pictures and scanning questions, the cursor light first forms a cursor projection area in the captured image, and then can identify and determine the content to be searched covered in the cursor projection area, and perform related searches on the content to be searched. [0003] Generally, the cursor projection area formed by the cursor light can only cover one or a few characters. If the user needs to search for more characters, the user needs to keep moving the smart terminal so that the cursor projection area cov...
