More Information
Summary:The invention discloses a high-precision infrared touch frame touch object size identification algorithm, which is based on the theory of similar triangles, rapidly calculates the size of a touch point and greatly improves the accuracy of touch point size identification, and relates to the technical field of software identification algorithms. The invention relates to the technical field of software recognition algorithms. According to the touch object size identification algorithm of high-precision infrared touch frame software, a plane scanning mode is no longer adopted; insteadly, a scanning mode of multi-emitter and one-receiver is adopted; infrared light is continuously emitted to a receiving lamp by a plurality of emitting lamps; the obtained result is a shielding object with the same size; the probability of shielding infrared rays is increased; the algorithm is high in calculation speed and relatively accurate in calculation, can be well applied to a high-precision infrared touch frame, and avoids the
