The invention provides inclined shooting teaching equipment. The inclined shooting teaching equipment comprises an image acquisition device, a display screen, a bracket, a base and a processor, the bracket is fixed on the base, and the back surface of the display screen is fixed on the bracket; the image acquisition device is mounted at the upper part of the display screen, and a lens of the imageacquisition device inclines downwards and is used for acquiring desktop images; and the processor is arranged in the teaching equipment and is used for acquiring the desktop image acquired by the image acquisition device, amplifying and compensating the desktop image according to the equipment parameters of the image acquisition equipment and generating a compensated desktop image. According to the teaching equipment provided by the embodiment of the invention, additional arrangement of a supporting rod is not needed, and the hardware cost can be reduced; and the desktop image is shot in an inclined mode, the intersection between the acquisition range of the image acquisition device and the activity space of the user can be reduced, so that the possibility of acquiring body parts or otherobjects of the user is reduced, and the image acquisition device is effectively prevented from being shielded by the user or other objects.
Description
technical field [0001] The invention relates to the technical field of teaching instruments, in particular to a teaching equipment for oblique shooting. Background technique [0002] At present, in the field of live interactive teaching, the equipment used for live broadcast needs to collect images of the user's desktop. In order to capture undistorted images, it is generally necessary to set the camera directly above the desktop. For the structural diagram of traditional equipment, see figure 1 As shown in FIG. 1 , the device requires an additional horizontally arranged pole on which the camera for photographing the desktop is installed to realize the collection of undistorted desktop images. [0003] In order to prevent image distortion, traditional devices need to set additional poles, which increases hardware costs; and when the user's body parts or other objects are above the table, it is easy to block the camera from collecting images normally.
