Embodiment 1

[0052] see figure 2 , figure 2 It is a schematic flowchart of a method for searching questions by taking photos disclosed in an embodiment of the present invention. like figure 2 The shown method for searching questions by taking photos may include the following steps:

[0053] 101. The handheld camera device responds to the frame selection instruction and projects an explicit frame on the projection surface where the test questions are located; wherein, the explicit frame is used to frame select at least one test question to be tested on the projection surface.

[0054] In the embodiment of the present invention, the handheld camera device (for example, a search pen) may respond to a frame selection instruction, and the frame selection instruction may be triggered by the user lightly pressing the camera key. Wherein, the shooting key is a physical button set on the handheld camera device, and the physical button may be a nested structure including double buttons (it sho...

Embodiment 2

[0071] see image 3 , image 3 It is a schematic flowchart of another method for searching questions by taking pictures disclosed in the embodiment of the present invention. like image 3 The shown method for searching questions by taking photos may include the following steps:

[0072] 201. The handheld camera device senses the first pressure value that the user acts on the camera button through the camera button of the handheld camera device.

[0073] In the embodiment of the present invention, the hand-held camera device may include a pressure sensor, and the hand-held camera device may calculate the first pressure value based on the readings of the pressure sensor.

[0074] 202. The handheld photographing device determines a first target pressure threshold range to which the first pressure value belongs from at least one preset pressure threshold range.

[0075] 203. The handheld camera device judges whether the first target pressure threshold range is the first pressu...

Embodiment 3

[0094] see Figure 6 , Figure 6 It is a structural schematic diagram of a hand-held photographing device disclosed in an embodiment of the present invention. Such as Figure 6 As shown, the handheld camera device may include:

[0095] The focus positioning unit 601 is configured to respond to the frame selection instruction and project a dominant frame on the projection surface where the test questions are located; wherein, the dominant frame is used to frame select at least one test question to be tested on the projection surface.

[0096] In the embodiment of the present invention, in the embodiment of the present invention, the focus positioning unit 601 (for example, a search pen) can respond to a frame selection instruction, and the frame selection instruction can be obtained by the user lightly pressing the shooting key (not in Figure 6 drawn in the middle) to trigger. Wherein, the shooting key is a physical button set on the handheld camera device, and the physica...

Abstract

The invention discloses a photographing question-searching method and system and handheld photographing equipment. The method comprises the steps that the handheld photographing equipment projects a dominant frame on a projection plane where test questions are located in response to a box selection instruction, wherein the dominant frame is used for box-selecting at least one to-be-tested test question in the projection plane; the handheld photographing equipment detects whether the projection direction of the projected dominant frame is perpendicular to the projection plane or not, wherein the photographing direction of a camera of the handheld photographing equipment is the same as that of the projection direction, and if not, the projection direction is adjusted till the projection direction is perpendicular to the projection plane; the handheld photographing equipment photographs the area where the dominant frame is located through the camera to obtain test question images, and then sends the test question images to electronic equipment to make the electronic equipment output the test question images and upload target to-be-tested test questions in the test question images to aserver to obtain target answer information corresponding to the target to-be-tested test questions. By means of the photographing question-searching method and system and the handheld photographing equipment, the question-searching efficiency and accuracy can be improved.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, in particular to a method and system for taking photos and searching for questions, and a handheld camera device. Background technique [0002] At present, with the popularization of online learning methods of taking photos and searching questions, more and more application software for solving homework problems have appeared on the market. [0003] Usually, students need to go through the following steps to complete the whole process of taking pictures and searching questions when using this kind of application software: unlock the mobile phone / tablet computer—find the application software for taking pictures and searching questions—start the application software—start the camera function in the application software—focus Take a picture of the question and get the test question image—confirm the test question image and upload the test question image to the server—the server ...
