The three-dimensional roaming mode of the agricultural park based on the VR technology breaks through the limitations of time and space in the display design of the traditional agricultural park, and from the perspective of a user, the agricultural park is displayed in a three-dimensional and all-dimensional mode, so that the user participates in the agricultural park, and the three-dimensional roaming mode generates interaction, and gives people a feeling of being personally on the scene.
The user wears VR head-mounted device, like HTC Vive, catches user's removal data and moving direction under the real environment through two infrared sensor of HTC Vive self-band, and in virtual scene, virtual user also can move. Through the interactive mode, the user can perform autonomous roaming in the constructed virtual scene. However, because the user wears VR glasses, the sight is sheltered from by the VR glasses, and external environment can not be perceived, and the removal in-process can appear hitting the wall or stumble the phenomenon by the connecting wire, has certain potential safety hazard.
Due to the above-mentioned drawbacks, in the agricultural park roaming system, the user is generally restricted from walking in the exhibition space, and the virtual perspective of the user is usually transmitted to the destination directly based on a virtual transmission mechanism. For example, a user may need to walk to point B in a real simulation situation at point a of the campus. But in order to ensure user security, the user can go directly from point a to point B via the virtual delivery mechanism. Due to the design mode, the action simulation of walking of the user is lacked, so that the participation sense of the user is insufficient, and the virtual scene cannot be really merged.

In consideration of the digital display process of the agricultural park, gesture action information of a user is collected through gesture capture equipment to complete corresponding interactive operation or farming operation. The method generally uses a Leap Motion device to collect gesture actions of a user, customize an action analysis module, and identify actions of the user such as clicking, grabbing and touching. However, the Leap Motion has a collection range of 25 mm to 600 mm, and both hands are required to be within a detectable range of the device, which brings inconvenience in a virtual farming operation process. Moreover, the device cannot provide tactile feedback, and a user cannot sense whether to trigger corresponding virtual operation, so that the gesture motion of the user cannot be captured finely.
