Problems solved by technology
[0002] Most of the existing handwriting recognition functions are realized by input methods on a two-dimensional plane such as a touch screen or a handwriting tablet. As for the somatosensory operation technology that detects the user's body movements in a three-dimensional space, such as Microsoft's somatosensory game controller Kinect and LeapMotion motion controllers lack the application of handwriting recognition, because in the two-dimensional plane input method, the process from the beginning to the end of a stroke can be detected by, for example, "whether the finger touches the touch surface". Body movements moving in three-dimensional space will be sensed throughout a specific space range, and there is no concept like "whether it touches the surface" or not

Embodiment Construction
[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0022] refer to figure 1 , illustrating that the preferred embodiment of the method for obtaining the three-dimensional space handwriting trajectory of the present invention is executed by an electronic device 1, which is, for example, a smart TV or a computer, including a processing unit 11, a storage unit 12, A display unit 13 , a transmission unit 14 , and a network unit 15 . The processing unit 11 also receives a film including a plurality of continuous images recorded by a photographing device 2 and performs image analysis. The camera device 2 is, for example, a general network camera or a stereo camera with specific sensory detection function. The transmission unit 14 is wirelessly connected to an input device 8 such as a personal digital assistant (PDA, Personal Digital Assistant), a tablet computer, or a smart phone. The network unit 15 is ...

The invention discloses a three-dimensional space handwriting trajectory acquisition method, which is executed by an electronic device. The electronic device comprises a processing unit, wherein the processing unit receives a film which comprises a plurality of continuous images and carries out image analysis. The method comprises the following steps: (A) the processing unit judges whether a first hand part in the film conforms to a trajectory starting gesture or not, and if the first hand part in the film conforms to the trajectory starting gesture, going to a step (B); (B) the processing unit records the position of the first hand part as a handwriting trajectory; (C) the processing unit judges whether the first hand part in the film conforms to a trajectory ending gesture or not, and if the first hand part in the film conforms to a trajectory ending gesture, going to a step (D); and (D) the processing unit finishes the record of the handwriting trajectory. The handwriting trajectory begins to be recorded through the judgment of the trajectory starting gesture, the trajectory ending gesture is judged to finish the record of the handwriting trajectory, and the handwriting trajectory in the film can be obtained.
Description
technical field [0001] The invention relates to a method for obtaining handwriting traces, in particular to a method for obtaining handwriting traces in three-dimensional space. Background technique [0002] Most of the existing handwriting recognition functions are realized by input methods on a two-dimensional plane such as a touch screen or a handwriting tablet. As for the somatosensory operation technology that detects the user's body movements in a three-dimensional space, such as Microsoft's somatosensory game controller Kinect and LeapMotion motion controllers lack the application of handwriting recognition, because in the two-dimensional plane input method, the process from the beginning to the end of a stroke can be detected by, for example, "whether the finger touches the touch surface".
