Résumé
Point cloud processing is how machines clean, organize, and understand these raw 3D dots to recognize, segment, and navigate the world.

What is Point Cloud Processing?
Niir poñ mooy benn poñ 3D (X, Y, Z) buy jàpp jëmmu mbir ak bayaal dëgg, lu ci bari ci LiDAR wala ci kaptër yu xóotaayu. Point cloud processing mooy anam wi masin yi di setalee, yamale, ak xam tombi 3D yu ñor yii ngir xàmmee, xaaj ak doxantu ci àdduna bi.
Luy niir poñ?
Niir poñ mooy poñ yu bari yu am coordonnée X, Y, Z (muy luñu boole ci melo wala doole) yuy jàpp geometrie mbir yi ak seen yi.
Lu tax mënu ñu jëfandikoo CNNs nataal yiñ miin ci niir yu am poñ yi?
Nataalu CNN yi dañuy xalaat griy pixel bu takku, waaye niir yi duñu yamale te duñu ranger, moo tax dañu soxla architecture yu yam.
Ban màndarga bu am solo la reso cloud point wara jox cër?
Ginaaw benn niir bi mën nañu ko lim ci xeetu rang bumu mëna doon, reso bi dafa wara génne ay génne yu nuróo ak rang bumu mëna doon.
naka la ko PointNet mënee moom boppam ci wàllu yoon?
PointNet dafay liggéey ci poñ bu nekk ak reso buñ bokk, ba noppi boole ci max-pooling, muy symétrique te du bàyyi xel ci komànd.
Luy algorithm bi gëna jege (ICP) di def?
ICP dafay baamtu méngale poñ yi gëna jege diggante ñaari scanner ba noppi gis coppite bu dëgër bi leen gëna méngale, ñu jëfandikoo ko ngir bind.
