Most　of　the　current　online　teaching　platforms　use　ordinary　monocular　cameras　to　capture　teaching　courses,　and　many　teaching　videos　just　record　the　offline　teaching　process　and　then　put　them　on　the　online　platform.　This　kind　of　teaching　course　is　not　immersive　enough,　students　cannot　get　a　sense　of　presence　when　learning　through　the　online　platform,　and　they　cannot　get　answers　in　time　when　they　have　questions,　which　will　affect　the　students＇　learning　effect.　Compared　with　the　video　collected　by　the　ordinary　camera,　the　panoramic　video　obtained　from　the　panoramic　camera　has　a　wider　field　of　view　and　a　better　sense　of　presence　and　immersion.　Our　system　uses　panoramic　cameras　to　collect　on-site　teaching　videos　to　form　360-degree　viewable　course　videos　and　upload　them　to　the　server　for　storage.　At　the　same　time,　a　question-and-answer　dialogue-assisted　teaching　robot　that　can　interact　with　voice　is　constructed　through　a　server-side　dialogue　Q&A　module.　The　client　is　used　to　display　the　interactive　interface　of　panoramic　video　courses　and　dialog　with　the　question-answering　robot　teaching　assistants.　Students　can　consult　the　＇robot　assistant＇if　they　have　any　questions　when　watching　the　course　videos　through　the　client.　This　creates　an　＇immersive＇learning　atmosphere　and　avoids　repetitive　work　by　the　instructor　while　achieving　better　learning　results.　©　2022　IEEE.
