Referring to fig. 1, the present embodiment provides an AR display device including an image capture device 400, an image processing device 200, AR glasses 300, and a power supply 100. And wherein the image capturing device 400 is used to capture images. The image processing device 200 is connected to the image capturing device 400 and the AR glasses 300, and configured to perform processing related to AR display on an image captured by the image capturing device 400, and send the processed image to the AR glasses 300. The AR glasses 300 are used to display the processed image. And the power supply 100 is connected to the image processing apparatus 200 for supplying power to the image processing apparatus 200.

As described in the background, the problem of endurance of AR glasses is becoming more and more prominent. Since the AR glasses require the user to wear, the battery of the AR glasses cannot be made too large, and thus the endurance problem cannot be solved by providing the AR glasses with a large-capacity battery. In addition, at present, the AR glasses generally adopt the HDMI interface, and the problem that transmission is unstable, easy to loosen and easy to be interfered by the environment can appear in this kind of interface to the HDMI interface also can not be for the power supply of AR glasses, consequently also can not effectively solve the continuation of journey problem of AR glasses.

In view of the above technical problems in the background art, the present application provides an AR display device. The AR display device is provided with an image processing device 200 between AR glasses 300 and an image capture device 400. The image capturing apparatus 400 first performs capturing of an image and then transfers the captured image to the image processing apparatus 200. The image processing apparatus 200 performs processing related to AR display on the received image and transmits the processed image to the AR glasses 300. The AR glasses 300 may display the final image.

Thus, the present invention peels off the image processing related to the AR display from the AR glasses 300, and performs the corresponding processing by the image processing apparatus 200 which is independently provided. Thus, in this way, the image processing circuit with the largest power consumption can be separated from the AR glasses 300, thereby reducing the power consumption of the AR glasses 300 and improving the cruising ability of the AR glasses 300.

And the AR display apparatus of the present invention is also provided with the power supply 100 alone, so that power can be supplied to the image processing apparatus 200 through the power supply 100. Wherein the power source 100 may be, for example, a relatively large capacity battery. As described above, since the image processing apparatus 200 is provided separately from the AR glasses 300. Therefore, the image processing apparatus 200 can be worn around the waist, wrist, upper arm, or the like of a human body during use, and it is thus appropriate to provide a battery with a large capacity to power the image processing apparatus 200. Thus, compared with the prior art in which the image processing apparatus 200 is integrated with the AR glasses 300, the cruising ability of the image processing apparatus 200 can be ensured without providing a large-capacity battery on the AR glasses.

Therefore, by the arrangement, the cruising ability of the AR glasses 300 and the image processing device 200 can be increased, and the technical problem that the AR glasses cannot continue cruising for a long time due to the fact that power cannot be supplied to the AR glasses for a long time in the prior art is solved.

Alternatively, the image processing apparatus 200 includes an image processor 210 and a first serializer 220, the AR glasses 300 includes a first deserializer 310 and an AR display 330, and the first serializer 220 and the first deserializer 310 are connected by a first serial transmission cable, wherein the image processor 210 is configured to perform processing related to AR display on an image received from the image capturing apparatus 400, and transmit the processed image to the first serializer 220. The first serializer 220 is configured to convert the processed image into a serial signal and transmit the converted serial signal through a first serial transmission cable. The first deserializer 310 is configured to receive the serial signal transmitted by the first serializer 220 through the first serial transmission cable, perform deserializing processing on the received serial signal, and generate a deserialized image signal. And an AR display 330 is connected to the first deserializer 310 for displaying the deserialized image.

As described in the background art, the current AR glasses generally use the HDMI interface, and such an interface may have the problems of unstable transmission, easy loosening, and easy environmental interference. In view of this, the present invention does not adopt the HDMI interface for image transmission between the image processing apparatus 200 and the AR glasses 300. Referring to fig. 1, the image processor 210 of the image processing apparatus 200 performs processing related to AR display on an image captured from the image capturing apparatus 400 and then transmits the processed image to the first serializer 220. The first serializer 220 receives the processed image, converts the processed image into a serial signal, and transmits the converted serial signal to the first deserializer 310 of the AR glasses 300 through the first serial transmission cable. The first deserializer 310 receives the serial signal transmitted through the first serial transmission cable, deserializes the serial signal to generate a deserialized image, and transmits the deserialized image to the AR display 330. The AR display 330 receives the deserialized image and displays it. Thus, in this way, the present invention transmits image signals between the image processing device 200 and the AR glasses 300 in a serial signal manner, so that the transmitted signals are more stable and less susceptible to environmental interference.

Optionally, the AR glasses 300 further include a first protocol converter 320, where the first protocol converter 320 is disposed between the first deserializer 310 and the AR display 330, and is configured to convert a protocol of the deserialized image signal generated by the first deserializer 310 into a receiving protocol adapted to the AR display 330. Referring to fig. 1, the first deserializer 310 transmits the deserialized image to the first protocol converter 320, and the first protocol converter 320 converts the protocol of the deserialized image signal into a receiving protocol adapted to the AR display 330 and transmits the image signal to the AR display 330. The AR display receives the image signal and displays an image on the AR glasses. Thus, in this way, on the premise of realizing the image transmission between the image processing device 200 and the AR glasses 300 through the serial signal, the matching of the transmission protocol between the first deserializer 310 and the AR display 330 inside the AR glasses 300 is further realized. Thereby enabling the AR glasses 300 to display the transmitted image.

Alternatively, the image capturing apparatus 400 includes a sensor 430 and a second serializer 410, the image processing apparatus 200 includes a second deserializer 230, and the second serializer 410 and the second deserializer 230 are connected by a second serial transmission cable, wherein the sensor 430 is used to capture an image. The second serializer 410 is connected to the sensor 430, and is configured to convert an image collected by the sensor 430 into a serial signal and transmit the converted serial signal through a second serial transmission cable. And the second deserializer 230 is connected to the image processor 210, and is configured to receive the serial signal transmitted by the second serializer 410 through the second serial transmission cable, perform deserialization on the received serial signal to generate a deserialized image signal, and transmit the deserialized image signal to the image processor 210.

At present, the AR glasses generally adopt HDMI interfaces when the images are collected and processed, and the problems of unstable transmission, easy looseness and easy environmental interference can occur in the interfaces. In view of this, the present invention does not adopt the HDMI interface to perform image transmission between the image capturing apparatus 400 and the image processing apparatus 200. Referring to fig. 1, a sensor 430 of an image pickup apparatus 400 transmits a picked-up image to a second serializer 410. The second serializer 410 converts the image collected by the sensor 430 into a serial signal and then transmits the converted serial signal to the second deserializer 230 of the image processing apparatus 200 through the second serial transmission cable. The second deserializer 230 receives the serial signal transmitted by the second serial transmission cable, deserializes the received serial signal, generates a deserialized image signal, and transmits the deserialized image signal to the image processor 210. Thus, in this way, the utility model discloses a serial signal's mode carries out image signal's transmission between image acquisition equipment 400 and image processing equipment 200 to make the signal of transmission more stable, and be difficult for receiving the interference of environment.

Optionally, the image capturing apparatus 400 further includes a second protocol converter 420, where the second protocol converter 420 is disposed between the second serializer 410 and the sensor 430, and is configured to convert a transmission protocol of the image captured by the sensor 430 into a receiving protocol adapted to the second serializer 410. Referring to fig. 1, the sensor 430 transmits the captured image to the second protocol converter 420, and the second protocol converter 420 converts the transmission protocol of the captured image into a reception protocol adapted to the second serializer 410 and transmits the image signal to the second serializer 410. The second serializer 410 receives the image signal and converts the acquired image signal into a serial signal. Thus, in this way, on the premise that the serial signal transmission between the image capturing apparatus 400 and the image processing apparatus 200 is realized, the matching of the transmission protocol between the second serializer inside the image capturing apparatus 400 and the image processing apparatus 200 is further realized, thereby enabling the image processing apparatus 200 to perform processing related to AR display on the image.

Optionally, the image processing apparatus 200 includes a power interface 240 connected to the power supply 100 for supplying power to the image processor 210, the first serializer 220, and the second deserializer 230. Referring to fig. 2, the power supply 100 is connected to a power interface 240 on the image processing apparatus 200, and supplies power to the image processor 210, the first serializer 220, and the second deserializer 230 in the image processing apparatus 200 through the power interface 240. So that the first serializer 220 can supply power to the AR glasses 300 through the first serial transmission cable and the second deserializer 230 supplies power to the image pickup device 400 through the second serial transmission cable.

Alternatively, the power interface 240 of the image processing apparatus 200 is also connected to a first serial transmission cable, and the power interface 331 of the AR display 330 is connected to the first serial transmission cable, to which the power interface 321 of the first protocol converter is connected. Referring to fig. 2, the power supply 100 is connected to the power interface 240, and the power interface 240 transmits power to the AR display 330 and the protocol converter 320 connected to the first serial transmission cable through the first serial transmission cable, thereby supplying power to the AR glasses 300. In this way, the AR glasses 300 can thus be power-transmitted using the first serial transmission cable between the image processing apparatus 200 and the AR glasses 300, thereby increasing the cruising ability of the AR glasses 300.

Alternatively, the power interface 240 of the image processing apparatus 200 is also connected to a second serial transmission cable, and the power interface 431 of the sensor 430 is connected to the second serial transmission cable, and the power interface 421 of the second protocol converter 420 is connected to the second serial transmission cable. Referring to fig. 2, the power supply 100 is connected to the power interface 240, and the power interface 240 transmits power to the sensor 430 and the protocol converter 420 connected to the second serial transmission cable through the second serial transmission cable, so as to supply power to the image capturing apparatus 400. In this way, the image capturing apparatus 400 can be power-transmitted using the second serial transmission cable between the image processing apparatus 200 and the image capturing apparatus 400, thereby solving the problem of power supply of the image capturing apparatus 400.

Optionally, the sensor 430 in the image capturing device 400 is a thermal infrared image sensor and/or a visible light sensor. Therefore, as the sensor 430 can adopt a thermal infrared image sensor, the visual problem of a moving scene under the condition of no light at night can be solved.
