Abstract
Embodiments of the present application provide a method and an apparatus for determining a position of a touch point. The method includes: determining, according to a scanning frame, a plurality of scanning infrared transmitting tubes; controlling a target scanning infrared transmitting tube to transmit an infrared signal, and controlling multiple groups of corresponding infrared receiving tubes to receive the infrared signal in sequence so as to obtain scanning data corresponding to the target scanning infrared transmitting tube; updating the target scanning infrared transmitting tube to be any one of scanning infrared transmitting tubes that have not been used for scanning, to repeatedly perform the step of controlling the target scanning infrared transmitting tube to transmit an infrared signal until obtaining scanning data corresponding to all scanning infrared transmitting tubes; and determining, according to the scanning data corresponding to all scanning infrared transmitting tubes, the position of the touch point.
