Summary:An intelligent trajectory acquisition pen, which relates to the technical field of intelligent pens, comprising: a pressure switch module, which is arranged on a pen tip part of the intelligent trajectory acquisition pen; an infrared light emitting circuit, which emits an infrared light signal to a writing region where the pen tip is in contact with a writing paper; a camera acquisition module, which acquires the trajectory formed by the pen tip in the writing region to form trajectory information; a MCU module, which performs data conversion processing on the trajectory information by means of a preset data processing algorithm to form a trajectory digital signal; a memory, which is used to store the trajectory digital signal formed by the MCU module; and a Bluetooth communication circuit, wherein after the intelligent trajectory acquisition pen and a target terminal are successfully communicatively connected, the Bluetooth communication circuit sends the trajectory digital signal stored in the memory to the
