Problems solved by technology

However, the current transmission scheme transmits uncompressed depth data through the network, the pressure on the stream bandwidth is high, and the number of concurrent networks is severely limited
[0007] Therefore, in view of the limited transmission distance of the above-mentioned USB direct connection method and the excessive pressure on the network transmission original depth data bandwidth, a more advanced depth data transmission technology is urgently needed.

Abstract

The invention relates to the field of data transmission, and discloses a depth data transmission method, which comprises the following steps of: encoding depth data into an RGB image according to a predetermined encoding format; transmitting the RGB image by adopting a video stream transmission protocol; receiving the RGB image; and decoding the received RGB image into the depth data according toa predetermined decoding format. The transmission bandwidth pressure can be effectively reduced, the network concurrence number is increased, and the depth information precision loss caused by transmission errors in the transmission process can be effectively reduced.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a depth data transmission technology. Background technique [0002] There are two ways to transmit data collected by existing depth cameras: [0003] 1. Connect to the corresponding host through direct connection of Universal Serial Bus ("USB"): [0004] The transmission distance of this method is limited by the length of the USB cable. The long-distance transmission of the USB cable requires additional signal amplification. The stability of the USB interface for a long time is not as stable as that of the network interface. The camera often means that the routing of the USB cable needs to be added, which increases the cost of using the depth camera; [0005] 2. Connect with the corresponding host through network cable connection, and transmit uncompressed original depth data: [0006] In this way, the transmission distance is not subject to signal attenuation, and the existin...
