Kediska Sawirka Sawirka

Jawaabaha iyo sharraxaadaha waxay soo baxayaan markaad qaadanayso kediska.

1. Waa maxay shuruudaha aasaasiga ah ee sawir gelinta si ay u shaqeyso?
   • Waa in lagu qaadaa toosh
   • Waa inay si weyn isu dul-maan oo ay goobta ka eegaan dhinacyo kala duwan
   • Dhammaantood waa in laga soo qaadaa isla boos isku mid ah
   • Waa inay ahaadaan madow iyo caddaan
2. Muxuu xisaabiyaa Qaab-dhismeedka-Motion (SfM)?
   • Kaliya midabada pixel kasta
   • Xaaladaha iftiinka ee goobta
   • Muuqaal kamarad guuraysa
   • Jagooyinka/jihaynta kamaradaha iyo set yar oo dhibco 3D ah isku mar
3. Maxaa xidhidhaynta yaraynaysaa?
   • Ciladda diidmada ee dhammaan kamaradaha iyo dhibcaha 3D
   • Wadarta cabbirka faylka sawirada
   • Tirada kamaradaha la isticmaalay
   • Isticmaalka batteriga inta lagu jiro qabashada
4. Waa maxay doorka Multi-View Stereo (MVS) ka dib SfM?
   • Si loo tirtiro sawiradii asalka ahaa
   • Si loo cadaadiyo meelaha kamarada ah
   • Si loo kala saaro dhibcaha aadka u yar ee daruur cufan ama mesh
   • Si toos ah sawirada dib loogu qaado
5. Waa maxay sababta dhibcaha xakamaynta dhulka (GCPs) inta badan loogu isticmaalo sawir-qaadista darajada sahaminta?
   • Si sawiradu u muuqdaan kuwo ifaya
   • Si loo kordhiyo tirada sawirada loo baahan yahay
   • Si meesha looga saaro baahida kamaradaha
   • Si aad moodo ugu dhejiso miisaanka-dhabta ah oo la isku duwo saxnaanta
6. Why can a textureless or strongly reflective surface be difficult for feature-based photogrammetry?
   • It guarantees that every camera pose is known exactly
   • It may provide few stable, repeatable visual correspondences across views
   • It makes image overlap unnecessary
   • It automatically supplies surveyed ground coordinates
7. What distinguishes camera intrinsics from camera pose in a photogrammetric reconstruction?
   • Intrinsics are scene-point coordinates and pose is only JPEG quality
   • Both terms mean only the camera's model name
   • Intrinsics describe projection properties such as focal length; pose describes position and orientation
   • Pose supplies the lens's distortion coefficients while intrinsics gives its geographic location
8. In a calibrated central-camera photogrammetry model, what geometric relation underlies triangulation?
   • A scene point, camera center, and its projection lie on a viewing ray
   • All scene points must share the same image pixel
   • Every photograph supplies absolute depth without another constraint
   • The camera center is always identical to the scene point
