Problems solved by technology

[0003] The process of the first type of framed questions is relatively cumbersome, and it also depends on the operator’s level of photography, which is too vague to perform follow-up operations; the second type of framed questions is easy to use, but there are also the following problems: in practice, due to the load The body may appear folds, curls, etc. During the process of framing, the operator often habitually presses one side of the carrier with one hand, and the other hand is used as the operating body to position the content of the frame selection. In this case, the camera will recognize multiple operating objects, and the smart device cannot make a preparation judgment for this situation. As a result, the specific content of the frame selection cannot be recognized, or the frame selection content is inconsistent with the user's needs.

Embodiment 1

[0060] see figure 1 , figure 1 It is a schematic flowchart of a frame selection method for photographs disclosed in an embodiment of the present invention. Wherein, the method described in the embodiment of the present invention is applicable to smart devices such as learning machines, tutoring machines, point readers, tablet computers or mobile phones with front cameras. Frame selection refers to selecting the corresponding content on the carrier according to preset rules for the positioning position of the operating body to take pictures, and the frame title is the frame selection content. Such as figure 1 As shown, the photo frame selection method includes the following steps:

[0061] 110. When a frame selection instruction is received, use the camera to obtain the position coordinates of the operating body on the carrier and the gaze area of ​​the operator's eyeballs on the carrier.

[0062] Box questions are used in learning, and their purpose can be to search questi...

Embodiment 2

[0109] When the operator uses an operating body such as a ruler to place it on the carrier, the position coordinates of multiple operating bodies may appear, and some or all of the position coordinates of these multiple operating bodies may fall into the gaze area, please refer to Figure 5 As shown, in this case, the method of taking pictures and frame selection includes:

[0110] 310. When a frame selection instruction is received, use the camera to obtain the position coordinates of the operating body on the carrier and the gaze area of ​​the operator's eyeballs on the carrier.

[0111] Step 310 is substantially the same as step 110 described in Embodiment 1, and will not be repeated here.

[0112] 320. When there are multiple position coordinates in the gaze area, determine whether the multiple position coordinates are continuous points.

[0113] For the presentation form in which the operating body is a finger, the multiple position coordinates in the gaze area are form...

Embodiment 3

[0129] see Figure 8 , Figure 8 It is a structural schematic diagram of a camera frame selection device disclosed in an embodiment of the present invention. Such as Figure 8As shown, the photo frame selection device can include:

[0130] The acquisition unit 610 is configured to use the camera to acquire the position coordinates of the operating body on the carrier and the gaze area of ​​the operator's eyeballs on the carrier when the frame selection instruction is received;

[0131] The execution unit 620 is configured to execute a first operation when there is only one position coordinate in the gaze area; the first operation is to execute the content on the carrier based on the position coordinate and preset rules Photograph.

[0132] As an optional implementation manner, the acquisition unit 610 may include a first unit 611 and a second unit 612, wherein the first unit 611 is used to obtain the position coordinates of the operating body on the carrier by using a came...

Abstract

The embodiment of the present invention relates to the technical field of smart devices, and discloses a method, device, electronic device and storage medium for frame selection of photos. The method includes: when a frame selection instruction is received, using the camera to obtain the position coordinates of the operating body on the carrier and the gaze area of ​​the operator's eyeballs on the carrier; there is one and only one in the gaze area When the location coordinates are set, a first operation is performed; the first operation is to take a photo of the content on the carrier based on the location coordinates and preset rules. By implementing the embodiment of the present invention, the content on the frame selection carrier can be realized through the combination of operator positioning and eye tracking technology, which can eliminate the inability to identify the specific frame selection content caused by multiple operators, improve the accuracy of frame questions, and improve the efficiency of frame questions .

Description

technical field [0001] The present invention relates to the technical field of smart devices, and in particular to a method, device, electronic device and storage medium for frame selection of photos. Background technique [0002] At present, smart devices such as learning machines and tutoring machines have the function of framing questions. The framing methods are roughly divided into two categories. One is to take pictures of the content to be selected by the carrier (such as a book) through the rear camera of the smart device; the other One type is mainly completed through the front camera of the smart device, which recognizes the position of the operating body (such as a finger) on the carrier, and then takes a photo of the content on the carrier based on the position. Box questions are mainly used for searching questions, or for storing knowledge points or wrong questions for future review. [0003] The process of the first type of framed questions is relatively cumbe...
