The embodiment of the present application discloses a handwriting generation method, device, terminal equipment, and computer storage medium. The method includes: using an image acquisition device to photograph the light spot projected by the digital pen on the writing surface when writing, so as to obtain a picture including the light spot. Frame or multiple frames of light spot images; the digital pen includes a light emitter, which is used to emit invisible light when the digital pen is writing, so as to form light spots on the writing surface; identify one or more light spots included in each frame of light spot images, and Determine the geometric characteristic parameters of each light spot in each frame of light spot image; according to the geometric characteristic parameters of each light spot image in each frame of light spot image, select the effective light spot of each frame of light spot image from each light spot included in each frame of light spot image; The effective light spot of the frame light spot image generates the handwriting of the digital pen, which can preserve the real writing experience for the user while digitizing the handwriting, and can improve the accuracy of handwriting generation.
Description
technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a handwriting generation method, device, terminal equipment and computer storage medium. Background technique [0002] At present, students can use tutoring machines, learning tablets and other educational terminal devices to assist their learning during the learning process. The terminal device can be provided with a touch-sensitive display screen, and students can use fingers or capacitive pens to write on the touch-sensitive display screen to simulate a real writing process. However, in practice, it is found that due to the influence of factors such as the area and sensitivity of the touch screen, there is often a certain difference between the handwriting generated by the terminal device and the real handwriting of the user, and the accuracy of handwriting generation is low. Contents of the invention [0003] The embodiment of the present application...
