The invention discloses a method for realizing
manual annotation in an electronic
system and is characterized in that the method comprises the following steps of: a, arranging a camera and a set writing plane, and determining a writing area according to a principle that the
visual range of the camera is within the writing plane; b, putting a piece of writing paper in the writing area, and manually annotating on the writing paper with a common pen by a user who faces to the camera; c, photographing the writing paper by the camera, and screening and
processing the photographed image by a
processing chip; and d, performing perspective correction on the initially annotated image by the
processing chip to generate a digitalized final
annotation image. The method for realizing the
manual annotation in the electronic
system has the advantages that the
manual annotation in the electronic
system can be effectively realized, the hardware cost for the manual
annotation is reduced, a real writing experience can be supplied to a user, and the writing quality of the user is improved; and therefore, the quality of the manual
annotation in the electronic system is improved.
