Drones ndi kuphunzira mozama

Mpunga, mbewu yaikulu yazakudya, imalimidwa pafupifupi mahekitala 162 miliyoni padziko lonse lapansi. Imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri powerengera kuchuluka kwa mpunga ndi kuwerengera mbewu za mpunga. Njirayi imagwiritsidwa ntchito kuyerekezera zokolola, kuzindikira kukula, ndikuwona kuwonongeka m'minda ya paddy. Njira zambiri zowerengera mpunga padziko lonse lapansi zikuchitikabe pamanja. Komabe, izi ndizotopetsa, zolemetsa, komanso zimatenga nthawi, kuwonetsa kufunikira kwa mayankho achangu komanso ogwira mtima opangidwa ndi makina.

Ofufuza ochokera ku China ndi Singapore posachedwapa apanga njira yosinthira kuwerengera mpunga pamanja ndi njira yaukadaulo kwambiri, yokhudzana ndi kugwiritsa ntchito magalimoto osayendetsedwa ndi ndege (UAVs) kapena ma drones.

Malinga ndi Pulofesa Jianguo Yao wochokera ku Nanjing University of Posts and Telecommunications ku China, yemwe adatsogolera kafukufukuyu, "Njira yatsopanoyi imagwiritsa ntchito ma UAVs kujambula zithunzi za RGB - zithunzi zomwe zimapangidwa makamaka ndi kuwala kofiira, kobiriwira, ndi buluu - kumunda wa paddy. Zithunzizi zimasinthidwa pogwiritsa ntchito a mfundo zakuya network zomwe tapanga, zotchedwa RiceNet, zomwe zimatha kuzindikira molondola kuchuluka kwa mbewu za mpunga m'munda, komanso kupereka mawonekedwe apamwamba kwambiri, monga malo a mbewu ndi kukula kwake.

Pepala lawo lasindikizidwa Zomera Phenomics.

Zomangamanga za netiweki za RiceNet zimakhala ndi chotsitsa chimodzi, chakutsogolo, chomwe chimasanthula zithunzi zolowera, ndi ma module atatu omwe ali ndi udindo woyerekeza kuchuluka kwa mbewu m'munda wa paddy, komwe kuli mbewu m'munda wa paddy, ndi kukula kwa zomera, motero. Zinthu ziwiri zomalizazi ndizofunikira kwambiri pa kafukufuku wamtsogolo wokhudza njira zoyendetsera mbewu, monga kupopera mbewu mankhwalawa.

Monga gawo la kafukufukuyu, gulu lofufuza lidatumiza makina a UAV okhala ndi kamera paminda ya mpunga mumzinda wa Nanchang waku China ndipo kenako adasanthula zomwe adapeza pogwiritsa ntchito zida zapamwamba. kusanthula zithunzi luso. Pambuyo pake, ofufuzawo adagwiritsa ntchito dataset yophunzitsira ndi dataset yoyeserera. Yoyamba idagwiritsidwa ntchito ngati chiwongolero chophunzitsira dongosolo ndipo chomalizacho chidagwiritsidwa ntchito kutsimikizira zomwe zapezedwa.

Mwachindunji, pazithunzi za 355 zokhala ndi mfundo zolembedwa pamanja 257,793, 246 zidasankhidwa mwachisawawa ndikugwiritsidwa ntchito ngati zithunzi zophunzitsira, pomwe 109 yotsalayo idagwiritsidwa ntchito ngati zithunzi zoyeserera. Chithunzi chilichonse chinali ndi mbewu 726 za mpunga.

Malinga ndi gululi, njira ya RiceNet yomwe imagwiritsidwa ntchito posanthula zithunzi ili ndi chiŵerengero chabwino cha phokoso ndi phokoso. M'mawu ena, imatha kusiyanitsa bwino mbewu za mpunga kuchokera ku maziko, motero kuwongolera mapu opangidwa ndi kachulukidwe a mbewu.

Zotsatira za kafukufukuyu zidawonetsa kuti cholakwika chamtheradi ndi mizu yolakwika ya njira ya RiceNet inali 8.6 ndi 11.2, motsatana. Mwa kuyankhula kwina, mapu a kachulukidwe opangidwa pogwiritsa ntchito RiceNet anali ogwirizana bwino ndi omwe amapangidwa pogwiritsa ntchito njira zamanja.

Kuphatikiza apo, kutengera zomwe adawona, gululi lidagawananso malingaliro angapo ofunikira. Mwachitsanzo, gulu silimalimbikitsa kupeza zithunzi pamasiku amvula. Imalimbikitsanso kusonkhanitsa zithunzi zochokera ku UAV mkati mwa maola 4 dzuwa litatuluka, kuti achepetse nthawi ya chifunga komanso kupezeka kwa ma curls a masamba a mpunga, zomwe zimasokoneza kwambiri kutulutsa kwake.

"Kuphatikiza pa izi, tidatsimikiziranso momwe tingagwiritsire ntchito njira yathu pogwiritsa ntchito ma dataset ena awiri otchuka. Zotsatirazo zinasonyeza kuti njira yathu imapambana kwambiri ndi njira zina zamakono. Izi zikugogomezera kuthekera kwa RiceNet m'malo mwa njira yakale yowerengera mpunga pamanja," amaliza motero Pulofesa Yao.

RiceNet imatsegulanso njira yopita ku njira zina za UAV- komanso njira zowunikira mozama za mbewu, zomwe zimatha kuwongolera zisankho ndi njira zopititsira patsogolo ulimi wa chakudya ndi mbewu zandalama padziko lonse lapansi.
