Abstract

The invention discloses a multi-target tracking method, and a touch screen control method and system. The multi-target tracking method comprises the steps of obtaining a predicted position point of each target in an (n+1)th frame according to the position of each target in first n frames, wherein n is greater than or equal to 2; detecting an actual position point of the target in the (n+1)th frame; and allocating an ID of the target corresponding to the predicted position point to the actual position point corresponding to the predicted position point in the (n+1)th frame. According to the multi-target tracking method provided by the invention, the predicted position point of each target is obtained at first and then the ID of the target corresponding to the predicted position point is allocated to the actual position point corresponding to the predicted position point, so that the allocation method is simple, the allocation speed is high, and the system resource occupation is small.

Description

technical field

[0001] The invention relates to the field of touch screens, in particular to a multi-target tracking method, a touch screen control method and a system. Background technique

[0002] In recent years, touch technology has gradually been widely used in general consumer electronic devices, such as smart phones, tablet computers, personal digital assistants, satellite navigation and so on. Compared with the traditional input methods such as mouse or keyboard, touch technology replaces hardware devices such as mouse or keyboard with fingers in the human body, and has a more humanized and intuitive operation method and interface. Therefore, more and more people use People like to use touch technology to control various electronic devices, and multi-touch technology brings revolutionary development to touch technology.

[0003] Multi-touch is a technology implemented jointly by human-computer interaction technology and hardware devices, which can realize human-comp...
