For convenience of the following description, in the present embodiment, the instant augmented reality navigation display system 1 is installed on a traveling vehicle, and the navigation information 150 generated by the navigation device 15 can be regarded as including the current position of the traveling vehicle. The real-time live image 130 captured by the real-time image capturing device 13 can be regarded as the surrounding environment of the vehicle in motion, such as roads and road trees, etc. The real-time live image 130 is a road image viewed by the driver of the vehicle, and The object contained in the live-action image 130 is a road divider that the driver sees from the front window of the vehicle. How the augmented reality device 11 generates the guidance information 117 will be explained below.

As can be seen from FIG. 1, the instant augmented reality device 11 includes a transmitting/receiving interface 111, a storage 113, a projector 114, and a microprocessor 115. The transmitting/receiving interface 111 is connected to the navigation device 15 and the live image. The capturing device 13, the user image capturing device 17 and the display device 19 are electrically connected.

Specifically, since the driver's binocular line of sight and the head will produce translational and upstream and downstream movements when the vehicle is traveling on the road surface, the microprocessor 115 can be used by the instant user image 170 in order to accurately generate the guidance information 117. In the middle, the driver's current line of sight angle is determined, that is, the virtual line of sight angle of the instant user image 170, and on the other hand, when the driver's face moves in the interior position, such as turning the head to the right window Looking at the camera and extending the head to the rear, the microprocessor 115 can determine the position of the face after the movement by the instant user image 170, that is, the virtual position of the instant user image 170.

The microprocessor 115 can further synthesize the guidance information 117 on the real-time live image 130 to generate the navigation image 119. The microprocessor 115 transmits the navigation image 119 to the display device 19 through the transmit/receive interface 111. The display device 19 can be A navigation image 119 is displayed for reference by the driver of the vehicle.

Specifically, the navigation image 119 is generated by the microprocessor 115 synthesizing the real-time live image 130 and the guide information 117. In other words, if the guide information 117 is an arrow symbol, the live-action image 130 will be combined with the arrow symbol. The navigation image 119 that the driver sees is generated by the real-time live image 130 with the guidance information 117 considering the vertical depth of view. The special information is required. The guidance information 117 can be other graphics, and the present invention is not limited thereto. range.
