Jawaabaha iyo sharraxaadaha waxay soo baxayaan markaad qaadanayso kediska.

  1. Waa maxay daruur dhibic?
    • Ururinta dhibcaha 3D ee qeexaya sagxadaha bannaan
    • Xariir 2D ah oo pixels midabka ah
    • Koox ka mid ah server-yada habeeya garaafyada
    • Khariidadda cimilada ee daboolka daruuraha
  2. Maxay tahay sababta sawirka caadiga ah ee CNN-yada si toos ah loogu dabaqi karin daruuraha?
    • Daruuraha dhibicda aad bay u yar yihiin
    • Dhibcuhu waa kuwo aan nidaamsaneyn oo waxaa ka maqan qaab-dhismeed shabakadeed joogto ah
    • Daruuraha dhibicda kuma jiraan macluumaad meel bannaan
    • CNN-yadu waxay ku shaqeeyaan kaliya madow iyo caddaan
  3. Waa maxay hantida muhiimka ah ee ay tahay in shabakada daruurtu ixtiraamto?
    • Kala-duwanaanshaha midabka
    • Amarka akhriska ee bidix ilaa midig
    • Kala duwanaansho la'aan si loo tilmaamo dalbashada
    • Xallinta sawirka go'an
  4. Sidee bay PointNet ku gaadhay kala danbayn-madaxbanaani?
    • Adigoo u kala saaraya qodobbada qaab alifbeeto ah
    • Adigoo marka hore dhibcaha u rogaya pixels
    • Adigoo iska tuuraya dhammaan marka laga reebo qodobka koowaad
    • Adigoo isticmaalaya hawl summeedka sida max-pooling in ka badan sifada dhibic kasta
  5. Muxuu sameeyaa Algorithm ee Barta Ugu Dhaw (ICP)?
    • Ku toosiya laba dhibcood oo daruuro ah oo isku xidha jir isku-dubbarid guud
    • Ku cadaadi daruuraha dhibcaha si loo kaydiyo
    • Midabada dhibcaha dherer ahaan
    • Ku ogaada wejiyada 3D scans
  6. Waa maxay sababta hoos u dhigista voxel si caadi ah loo isticmaalo?
    • Si aad ugu darto dhibco badan oo faahfaahsan
    • Si loo dhimo daruuro waaweyn oo cufan si loo maareeyo, cabbir isku mid ah oo dheeraad ah
    • Si loogu badalo xogta 3D maqal
    • Si loo sireeyo daruurta dhibicda
  7. What does PointNet++ add beyond PointNet’s independent per-point feature processing?
    • A fixed left-to-right order for every point cloud
    • An image-only convolution applied to RGB pixels
    • Hierarchical grouping of nearby points to learn local features at multiple scales
    • A rule that deletes every point outside the origin
  8. Why might a point-cloud pipeline remove statistical outliers before modeling?
    • To create an ordered sequence from the remaining points
    • To convert the cloud into a two-dimensional audio spectrogram
    • To add synthetic surface normals to every point
    • To discard isolated noisy points that do not fit the surrounding point distribution
