Embodiment 1

[0075] see figure 2 , figure 2 It is a schematic flowchart of a method for searching questions by photographing based on eye positioning disclosed in an embodiment of the present invention. Such as figure 2 As shown, this method for searching questions by taking photos based on eye positioning can include the following steps:

[0076] 201. The hand-held camera device detects the movement and positioning trajectory of the user's eyes on the surface where the test questions are located, wherein the surface where the test questions is located is used to present at least one test question, and the movement and positioning trajectory is obtained from at least one positioning point of the user's eyes on the surface where the test questions are located.

[0077] In the embodiment of the present invention, the hand-held camera device can identify the sight focus of the user's eyes on the surface where the test question is located through the eye tracker installed on the hand-held...

Embodiment 2

[0096] see image 3 , image 3 It is a schematic flow chart of another eye-positioning-based photographing and question-searching method disclosed in an embodiment of the present invention. Such as image 3 As shown, this method for searching questions by taking photos based on eye positioning can include the following steps:

[0097]301. The hand-held camera device detects the movement and positioning track of the user's eyes on the surface where the test questions are located, wherein the test question surface is used to present at least one test question, and the movement and positioning track is obtained from at least one positioning point of the user's eyes on the test question surface.

[0098] 302. When only one positioning point is included in the mobile positioning track, the handheld camera device determines the area to be photographed with one positioning point as the midpoint on the surface of the test question, and the area to be photographed is used to select a...

Embodiment 3

[0110] see Figure 4 , Figure 4 It is a schematic flow chart of another eye-positioning-based photographing and question-searching method disclosed in an embodiment of the present invention. Such as Figure 4 As shown, this method for searching questions by taking photos based on eye positioning can include the following steps:

[0111] Steps 401 to 402 are the same as steps 301 to 302, and the following content will not be repeated.

[0112] 403. The handheld camera device projects laser light on the area to be photographed to obtain a dominant frame, and the coverage area of ​​the dominant frame is the same as that of the area to be photographed.

[0113] In the embodiment of the present invention, the projection of laser light on the area to be photographed by the handheld camera device can be realized through laser display technology (Laser Display Technology, LDT). The handheld camera device can only project laser light on the boundary of the area to be photographed, ...

Abstract

The invention relates to the technical field of handheld photographing equipment, and discloses a method and system for searching questions based on eye positioning, and the handheld photographing equipment. The track determines the area to be photographed on the surface where the question is located, so as to select the question to be searched through the area to be photographed. Then, the handheld photographing device obtains the test question image by taking pictures of the area to be photographed, and sends the test question image to the electronic device, so that the electronic device obtains the answer corresponding to the test question. By implementing the embodiments of the present invention, the handheld photographing device can determine the area to be photographed according to the movement and positioning trajectory of the user's sight, avoiding the user's manual operation of selecting topics, thereby simplifying the process of photographing and searching questions, and improving the efficiency of searching for questions.

Description

technical field [0001] The present invention relates to the technical field of hand-held photographing equipment, in particular to a method and system for photographing and searching questions based on eye positioning, and a hand-held photographing equipment. Background technique [0002] With the increasingly close connection between the Internet and the education industry, many search applications for students have appeared on the market. When encountering a question that cannot be answered, students can use the search application on the mobile phone to take a photo to search for the question. The process of taking a photo to search for the question includes: power on - slide the screen to unlock - select the search application - start the application - start the camera - focus Take a picture - intercept test questions - confirm - upload to server - server identification - server matching test questions - server feedback answer information. In practice, it has been found ...
