RTK Yokha Siyokwanira? Kukwera kwa GNSS + IMU + Vision Fusion mu Precision Mapping

Kuyambira m'matauni kupita ku nkhalango zowirira, RTK yachikhalidwe nthawi zambiri imalimbana ndi zosokoneza. Yankho lake lili mu kuphatikizika kwa sensa - kuphatikiza GNSS ndi IMU ndi matekinoloje owonera.

Chovuta cha Pure RTK

RTK (Real-Time Kinematic) imadziwika popereka mawonekedwe a masentimita, koma magwiridwe ake amatha kufooka m'malo ovuta:

M'matauni canyons kumene ma skyscrapers amatchinga kapena amawonetsa ma satellite.
Nkhalango kapena tunnel kumene zizindikiro za GNSS zimafooketsa kapena kuzimiririka kwathunthu.
Mapulogalamu apamwamba kwambiri monga mapu a UAV, komwe kutayika kwa chizindikiro kwakanthawi kumabweretsa mipata mu data.

Zikatero, kudalira kokha Gnss Rtk imasiya akatswiri kuti adziwonetsere kuti ali ndi zotsatira zolakwika komanso zosagwirizana.

Sensor Fusion: The New Standard

Kuti athane ndi zofooka izi, makampaniwa akuphatikiza ma sensor fusion - kuphatikiza RTK ndi IMU (Inertial Measurement Unit) ndi machitidwe amasomphenya:

GNSS + IMU: Ngakhale ma siginecha a GNSS atsika kwakanthawi, IMU ikupitilizabe kuwerengera komwe kumayendera ndi kusuntha, kutseka kusiyana mpaka ma signature abwerere.
GNSS + Masomphenya: Pounika zithunzi za kamera, makina amatha kuzindikira malo omwe ali ndi malo ndikusinthanso kaimidwe, makamaka pazithunzi za 3D ndi mapu.
Triple Fusion: Kuphatikiza GNSS, IMU, ndi masomphenya kumapereka mphamvu pafupifupi m'madera onse, kuonetsetsa kupitiriza ndi kulondola.

Njira yophatikizira iyi ikusintha kulondola kwa mapu, kuyenda modziyimira pawokha, ndi ntchito yomanga padziko lonse lapansi.

Apex Gnss Zothetsera

Apeks GNSS yadziyika yokha patsogolo pakusinthika uku ndi olandila omwe amakumbatira ukadaulo wosakanizidwa:

AP10: Chophatikiza Gnss Receiver kwa ma UAV ndi mapulogalamu am'manja. Kapangidwe kake kopepuka kumapangitsa kukhala koyenera kwa madera omwe kulemera kwake kumafunikira, kwinaku akuthandizira kuphatikiza ndi machitidwe a IMU.
AP30 Laser: Pokhala ndi ukadaulo wa IMU wokhazikika komanso ukadaulo wa laser wobiriwira, AP30 Laser imatsimikizira malo okhazikika ngakhale nthawi ya GNSS yazimitsidwa - yabwino pakuwunika kwamatauni, kusanja kwa zomangamanga, ndi mapu a drone.
Chithunzi cha AP50: Kuphatikiza GNSS ndi kamera yoyang'ana kutsogolo, Masomphenya a AP50 amathandizira kuyika mothandizidwa ndi masomphenya. Izi zimapangitsa kuti ikhale yamphamvu kwambiri pamawonekedwe a 3D, ma photogrammetry, ndi ma smart-city applications.

Pamodzi, mayankho awa amaonetsetsa kuti akatswiri sakuyeneranso kuda nkhawa ndi zosokoneza. Ndi GNSS + IMU + fusion fusion, kulondola ndi kudalirika kumafikira malo omwe amaganiziridwa kuti ndi zosatheka kwa RTK.

Mapeto

Tsogolo la mapu olondola si RTK yokha, koma RTK imalimbikitsidwa ndi kuphatikiza kwa sensor. Kaya mukuwulutsa ma UAV, kuyang'ana malo omangira owundidwa, kapena kupanga mapu a madera akumatauni, kuphatikiza GNSS, IMU, ndi kuwona kumapereka malo odalirika a centimita - popanda kunyengerera.

Ndi zolandila za Apeks GNSS, akatswiri amapeza mwayi wopeza ukadaulo wotsatira uno waukadaulo, kuwonetsetsa kulondola, kuchita bwino, komanso kudalirika kulikonse komwe angawatengere.
