The invention discloses a virtual touch
system, an image identifying and locating method and a computer readable storage medium. The virtual touch
system comprises an image obtaining device, a
microcontroller and a
USB-HID description program module. The image obtaining device comprises two camera shooting points, and is used for constructing a virtual touch screen in front of a display screen / curtain; the
microcontroller is used for controlling the two camera shooting points to collect images simultaneously, executing an image identifying and locating program module to process the collected images, and obtaining position coordinates of touch points; the
USB-HID description program module is executed on the
microcontroller, and is used for encapsulating HID report descriptors of the touchposition coordinates, and sending the HID report descriptors to a computer associated with the display screen / curtain. By means of the virtual touch
system, the image identifying and locating method and the computer readable storage medium, the microcontroller is utilized to encapsulate the
touch function, and is independent from a computer system, and the
touch function of displaying equipment ofany size can be achieved; the virtual touch system is erected instantly and used instantly, and the displaying equipment does not need to be refit; meanwhile, boundaries are initialized, and the universality is high.
