1. A lossless AR video capture and transmission method, comprising:
converting combined analog electronic signals synchronously captured by a plurality of image sensors and a plurality of sound pickups into multi-channels of first digital signals;
losslessly converting the multi-channels of first digital signals into multi-channels of second digital signals;
obtaining multi-channels of first optical signals by performing respective photoelectric conversions on the multi-channels of second digital signals;
receiving the multi-channels of first optical signals, and converting the multi-channels of first optical signals into the multi-channels of second digital signals; and
parsing at least one channel of second digital signal among the multi-channels of second digital signals into an AR video,
wherein the converting combined analog electronic signals synchronously captured by the plurality of image sensors and the plurality of sound pickups into the multi-channels of first digital signals comprises: acquiring a combined analog electronic signal synchronously captured by one image sensor and at least one sound pickup corresponding to the one image sensor; and obtaining the multi-channels of first digital signals by respectively performing an analog-to-digital conversion on each of a plurality of the combined analog electronic signals,
wherein the obtaining the multi-channels of first optical signals by performing respective photoelectric conversions on the multi-channels of second digital signals comprises: obtaining multi-channels of MIPI signals by losslessly outputting, based on a MIPI protocol, each channel of first digital signal of the multi-channels of the first digital signals as a MIPI signal; and obtaining the multi-channels of first optical signals by performing respective photoelectric conversions on the multi-channels of MIPI signals, and
wherein by using a multiplexing technique, the multi-channels of first optical signals are modulated into at least one physical channel for transmitting the multi-channels of first optical signals.
