Track capturing device and teaching equipment

Abstract

The embodiment of the invention provides a track capturing device and teaching equipment. The track capturing device comprises a mounting rack, a light source, more than two image acquisition devices and a controller; the mounting rack is provided with a mounting part, and the mounting rack is connected with a blackboard through the mounting part; the light source is arranged on the mounting rack and is used for illuminating a recognition area; the more than two image acquisition devices are arranged on the mounting rack at intervals, and the image acquisition devices are used for capturing objects in the recognition area range in real time and sending a captured image recorded with an object to the controller in real time; and the controller acquires included angles between the object and the more than two image acquisition devices according to the images and calculates and acquires the current position of the object according to the included angles. According to the track capturing device and the teaching equipment, the trouble of frequent wiping and maintenance can be effectively avoided; meanwhile, the light source and the image acquisition devices are integrally arranged on the mounting rack, and the mounting rack is arranged on the single side of the blackboard, so that maintenance is simple, mounting is convenient, the whole track capturing device is attractive, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of interaction technology, in particular to a trajectory capturing device and teaching equipment. Background technique [0002] In the fields of education, training or office, in order to achieve good interaction, smart blackboards are usually used. The smart blackboard in the prior art consists of a display screen and blackboards arranged on both sides of the display screen. The display screen is used to display electronic content, such as PPT, video, etc., and the blackboard is used to present blackboard writing written by the lecturer with writing materials such as chalk. . Blackboard writing cannot be synchronized to the display screen located in the middle for viewing by people in different positions, nor can the content of blackboard writing be saved in the form of electronic files for later browsing. [0003] In order to solve the above problems, a frame structure unit such as an infrared touch frame or an op...

Problems solved by technology

[0003] In order to solve the above problems, a frame structure unit such as an infrared touch frame or an optical touch frame is usually installed on the blackboard to capture the position of the writing and send the coordinates to the computer. Dust coverage caused by chalk writing affects the capture of writing objects, so frequent wiping and maintenance are required
