Katedra \u0161peci\u00e1lnej geod\u00e9zie Stavebnej fakulty \u010cVUT v Prahe vykon\u00e1vala v obdob\u00ed od roku 2019 do roku 2022 v\u00fdskum slu\u017eby MawisPhoto. T\u00e1to slu\u017eba, ktor\u00fa vyvinula spolo\u010dnos\u0165 HRDLI\u010cKA spol. s r.o., je zalo\u017een\u00e1 na met\u00f3de fotogrametrie s vyu\u017eit\u00edm mobiln\u00e9ho telef\u00f3nu.

Doc. Ing. Rudolf Urban, Ph.D., sa v r\u00e1mci projektu venoval predov\u0161etk\u00fdm ter\u00e9nnym meraniam a optimaliz\u00e1cii obslu\u017enej aplik\u00e1cie vr\u00e1tane z\u00e1sad merania. Prof. Ing. Martin \u0160troner, Ph.D., ved\u00faci Katedry \u0161peci\u00e1lnej geod\u00e9zie, sa venoval najm\u00e4 anal\u00fdzam \u00faplnosti a presnosti modelov, optimaliz\u00e1cii a automatiz\u00e1cii postupu spracovania modelov.<\/p>\n\n\n\n

V are\u00e1li spolo\u010dnosti Hrdli\u010dka vznikol vzorov\u00fd v\u00fdkop, okolo ktor\u00e9ho bol vytvoren\u00fd polyg\u00f3n. Bodov\u00e9 pole polyg\u00f3nu bolo v miestnom s\u00faradnicovom syst\u00e9me a konkr\u00e9tne vyrovn\u00e1vacie body (pre skener aj sn\u00edmky) boli zmeran\u00e9 tot\u00e1lnou stanicou Trimble S9 HP. V r\u00e1mci v\u00fdskumu sa vykonalo testovanie postupov merania, rozmiestnenia a ozna\u010denia orienta\u010dn\u00fdch bodov, ale aj samotn\u00e9ho merania a sn\u00edmania, pri ktorom sa pou\u017eila kamera GoPro, mobiln\u00e9 telef\u00f3ny Samsung Galaxy S6, Samsung Galaxy S8 aj Lenovo Z6 Pro a vlastn\u00fd skript v jazyku Python. Na \u00fa\u010dely merania bola vykonan\u00e1 kalibr\u00e1cia a jedno sn\u00edmanie sl\u00fa\u017eilo na otestovanie kalibr\u00e1cie v programe Agisoft (Lenovo Z6 Pro). Na z\u00e1klade experimentu mo\u017eno kon\u0161tatova\u0165, \u017ee na presnosti zadan\u00fdch prekalibra\u010dn\u00fdch prvkov v z\u00e1sade nez\u00e1le\u017e\u00ed. Na \u00fa\u010dely porovnania \u00fadajov bol v\u00fdkop naskenovan\u00fd s vysokou presnos\u0165ou (v jednotk\u00e1ch mm) pomocou pozemn\u00e9ho skenera Leica P40.<\/p>\n\n\n\n

Fakulte boli na testovanie poskytnut\u00e9 aj \u00fadaje z r\u00f4znych v\u00fdkopov a pr\u00edstrojov. Ve\u013ek\u00e1 rozmanitos\u0165 ter\u00e9nov, sp\u00f4sobov sn\u00edmania a rozl\u00ed\u0161enia pri testovan\u00ed bola ve\u013emi prospe\u0161n\u00e1. Tieto \u00fadaje boli pou\u017eit\u00e9 na anal\u00fdzu \u0161pecifick\u00fdch situ\u00e1ci\u00ed a konfigur\u00e1ci\u00ed. V\u00fdpo\u010dty sa vykon\u00e1vali v softv\u00e9ri Agisoft Metashape a na vyhodnotenie (ur\u010denie presnosti at\u010f.) bol pou\u017eit\u00fd softv\u00e9r CloudCompare. Spracovali sa \u00fadaje z pribli\u017ene 5 komplexn\u00fdch testov a z pribli\u017ene 20 \u010fal\u0161\u00edch testov zameran\u00fdch na \u0161peci\u00e1lne situ\u00e1cie. Celkovo bolo spracovan\u00fdch viac ako 2 500 testov.
