Visual Odometry Quiz

Mhinduro uye tsananguro zvinoonekwa paunenge uchitora bvunzo.

1. Chii chinotariswa nekuona odometry?
   • Kuwedzera kwekufamba kwekamera (kutenderera nekushandura) nekufamba kwenguva
   • Kupisa kwemavara kwechiitiko
   • Nhamba yezvinhu zvinoonekwa
   • Mugadziri wekamera
2. Chii chinonzi 'drift' mukuona odometry?
   • Iyo kamera inotsvedza pairi pamusoro
   • Kurasikirwa kamwe kamwe kwese data data
   • Kuunganidzwa kwezvikanganiso zvidiki pa-frame inokura pamusoro penzira
   • Kutenderera kwemaune kwelenzi
3. Why is absolute scale ambiguous in ordinary monocular visual odometry without a metric reference?
   • A color sensor cannot detect image features
   • The image geometry can support differently scaled scenes and translations that project alike
   • Every monocular camera records absolute depth directly
   • A single-camera sequence has no rotation information at all
4. Kuona-inertial odometry inovandudza sei kusimba?
   • Nekuwedzera mamwe makamera emhando imwe chete
   • Nekudzikisa chiyero chechimiro
   • Nekushandura mifananidzo kuita zvinyorwa
   • Nekusanganisa data yekamera neIMU (accelerometer/gyroscope) zviyero
5. Yakajeka yekuona odometry inosiyana sei kubva kune yakazara yekuona SLAM?
   • VO inovaka mepu yepasi rose nekuvhara loop; SLAM inongoteedzera mafambiro emunharaunda
   • Vakafanana chaizvo
   • VO inotarisa pane yemuno furemu-ku-furemu kufamba, ukuwo SLAM ichivakawo nekuchengetedza mepu yepasirese nekuvharika kwechiuno.
   • SLAM haishandisi makamera zvachose
6. Ndedzipi nzira dzakananga dzekuona odometry dzinoderedza, pachinzvimbo chekufananidza zvinhu zvakajeka?
   • Photometric (pixel intensity) kukanganisa pakati pemafuremu
   • Nhamba yepixels mumufananidzo
   • Kushandiswa kwebhatiri rekamera
   • Mavara acho anoisa panzvimbo
7. What physical quantity gives a calibrated stereo visual-odometry system a metric reference?
   • The number of letters in the camera brand
   • The chosen image file extension
   • The scene's average pixel brightness alone
   • The known separation, or baseline, between the two cameras
8. Why can a moving vehicle in view interfere with a static-scene visual-odometry estimate?
   • Every tracked pixel must belong to a fixed background point
   • Its image motion includes object movement that is not explained by camera movement alone
   • Moving objects reveal the camera's manufacturer automatically
   • Object motion changes only the file's compressed byte count
