Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] Such as figure 1 Shown is a working flow chart of a three-dimensional space gesture operation method of the present invention, including:
[0021] Step S101, the somatosensory device detects the entry of an operation marker in the workspace, the workspace uses a three-dimensional coordinate system including the X-axis, Y-axis and Z-axis to identify the spatial position in the workspace, and the workspace The space is divided into multiple spatial regions along the Z axis, and the Z-axis position included in each spatial region is used as the Z-axis range of the spatial region;
[0022] Step S102, the host device obtains the Z-axis position of the operation marker from the somatosensory device as the operation Z-axis position, and if the operation Z-axis position is within the Z-axis range of one of the spatial regions, the Z-a...

The invention provides a three-dimensional gesture operation method and system. The method comprises the steps that: a somatosensory apparatus detects entry of an operation marker into a working space and divides the working space into a plurality of space regions along Z axis; a host apparatus obtains the Z axis position of the operation marker from the somatosensory apparatus as the operation Z axis position, and if the operation Z axis position is in the Z axis range of one space region, the space region with the Z axis range covering the operation Z axis position as the operation region the operation marker is located; the host apparatus performs corresponding operation according to the change of the operation X axis position and the operation Y axis position and the operation region the operation marker is located. The error accumulation caused by depth data in an operation process is reduced and the gesture identification accuracy is improved.
Description
technical field [0001] The present invention relates to the technical field of gesture operation control, in particular to a three-dimensional space gesture operation method and system. Background technique [0002] As wearable devices are gradually recognized by consumers, well-known domestic and foreign companies have begun to actively participate in the research of portable terminals in the consumer field. The operation of existing portable terminals usually relies on mechanical buttons, touch screen or voice interaction. In recent years, major manufacturers have successively developed gesture operation technologies, hoping to control the technology of portable terminals through gestures. [0003] At present, the main gesture operation method is an operation method based on vision gesture recognition, which includes a gesture image acquisition device and a controller, and realizes main functions including gesture image acquisition, image data entry, gesture image recogni...
