Abstract

The invention provides a method for automatically identifying a contact position in a display screen based on a touch control method, which comprises the following steps of setting a laser radar on aplane where the display screen is located, and acquiring all data point clouds through the laser radar; judging whether the new object corresponding to each data point cloud is an interference objector not; setting the data point cloud corresponding to the interference object as interference data; automatically prompting the positions of four vertexes of the boundary of the touch display screen through arrows by the display screen, touching the vertexes of the boundary according to a system arrow prompting sequence within a time threshold range, and automatically recording the coordinate values of contact positions; automatically calculating the corresponding relationship between the actual display screen and the original image interface position by the system; touching any position of the display screen to perform command operation by a user, automatically identifying the position of a contact by the system. Meanwhile, the corresponding position of the original image interface performs corresponding operation. The display screen is set to be the touch screen, man-machine interaction can be promoted, the sense of participation of user use comfort experience is higher, and the touch screen accuracy is higher.

Description

technical field [0001] The invention relates to the technical field of projection interaction, in particular to a method for automatically identifying the position of a touch point on a display screen based on a touch method. Background technique [0002] At present, multimedia technology is becoming more and more mature, but the most widely used in the existing market is to clearly display the pre-displayed picture through a large projection screen, or to display the image in the electronic device through an electronic display screen, by making the display interface smaller The picture is displayed through a large display screen, which brings great visual enjoyment to customers. However, while performing visual enjoyment, it is found that multimedia technology cannot perform good interaction, which also causes great troubles for users. [0003] In particular, the existing projected images are mainly obtained by projecting with a projector, but the problem of deformation of...
