Description

head mounted display device

technical field

The invention relates to a head-mounted display device, in particular to a head-mounted display device suitable for model remote control.

Background technique

The current remote control models are all controlled by the operator holding the remote control and watching the distant model to control its posture and complete various actions. This also limits the model to be within the line of sight of the operator.

In recent years, with the miniaturization of electronic equipment, wireless video transmission equipment is installed on the model with very limited volume and load capacity, so as to realize the way of manipulating the model from the first perspective. The effect that can be achieved is that the range of the operator's operating model can be extended.

The display devices of the current models all use independent display screens and independent receiving antennas to realize video reception, and the operator must face the display screen to watch the images or videos collected by the model, so it cannot bring the operator personal experience. The effect of being on the scene, and this display method fixes the direction of the operator's field of vision, reduces the operator's sight range, and is not conducive to the operator's direct observation of the model. Therefore, the operation mode of independent display screen and independent receiving antenna is not conducive to the operator's control of the model, and the user experience is poor.
