Embodiment 1

[0067] see figure 2 , figure 2 A schematic flow chart of a search method based on three-dimensional space positioning disclosed in an embodiment of the present invention; figure 2 As shown, the search method based on three-dimensional space positioning is applied to figure 1 Tutoring equipment shown may include:

[0068] 201. Tutoring equipment When the user's hand is operating on the current page of the exercise textbook, the human body infrared light transmission device of the camera is used to detect the human body infrared light to obtain the original image data of the hand.

[0069] Wherein, the human body infrared light-transmitting device can be an infrared light-transmitting sheet arranged on the lens of the camera. The infrared light-transmitting sheet can only transmit human infrared light, so when the user's hand is operating in a designated shooting area, it can pass through the human body. It is detected by the infrared light-transmitting device.

Embodiment 2

[0083] see image 3 , image 3 It is a schematic flowchart of a search method based on three-dimensional space positioning disclosed in another embodiment of the present invention; image 3 As shown, the search method based on three-dimensional space positioning is applied to figure 1 As shown in the tutoring device, the method may include:

[0084] 301. The tutoring device detects whether a question search start instruction is received.

[0085] Wherein, when the command of starting the search question is received, turn to step 302, and when the command of starting the search question is not received, the procedure ends.

[0086] As an optional implementation, combining figure 1 , whether the tutoring device detects whether a search question start instruction is received may specifically include: whether the tutoring device detects whether the user's touch operation (including a click operation or a press operation) on the circular icon (smart learning mode) is received; ...

Embodiment 3

[0102] see Figure 4 , Figure 4 It is a schematic structural diagram of the tutoring equipment disclosed in an embodiment of the present invention; Figure 4 As shown, two cameras are installed on the same side of the tutoring equipment, the distance between the cameras meets the preset distance, the camera is equipped with a human body infrared light-transmitting device, and when the tutoring equipment is placed in a preset way, the camera corresponds to a designated shooting area , the designated shooting area is used to place practice materials, and further, the tutoring equipment may include:

[0103] The photographing unit 410 is used to detect the infrared light of the human body by the human body infrared light transmission device of the camera to obtain the original image data of the hand when the user's hand is operating on the current page of the exercise teaching material.

[0104] The positioning unit 420 is configured to perform three-dimensional modeling based...

Abstract

The embodiment of the invention discloses a searching method based on three-dimensional space positioning and family education equipment, and the method comprises the steps: enabling the family education equipment to detect human body infrared rays through a human body infrared ray light transmission device of a camera when hands of a user operate on a current page of an exercise teaching material, so as to obtain hand original image data; Performing three-dimensional modeling on the basis of the hand original image data, generating hand three-dimensional displacement data, and positioning anoperation position of the hand of the user on the current page of the practice teaching material according to the hand three-dimensional displacement data; when human body infrared rays are not detected by using a human body infrared ray transmitting device of the camera, controlling the camera to shoot a current page of the practice teaching material to obtain a current page image; identifying the teaching material content corresponding to the operation position from the current page image; searching based on the teaching material content to obtain a reference answer; contents needing to be searched can be intelligently positioned, and the contents needing to be searched are accurately identified, so that the search accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of tutoring equipment, in particular to a search method based on three-dimensional space positioning and tutoring equipment. Background technique [0002] Most of the existing tutoring equipment has the function of taking photos and searching questions, that is, the user can take pictures of the content to be searched by using the camera on the tutoring equipment to obtain the corresponding image, and then identify the content from the image and search for the content. Search for corresponding reference answers. However, the operation process of this kind of photo search is relatively cumbersome, and for younger users, it is impossible to prepare to capture the content they want to search, thus affecting the search rate. Contents of the invention [0003] The embodiment of the present invention discloses a search method and tutoring equipment based on three-dimensional space positioning, which can intelli...
