MCMOT : multi-camera multi-object tracking
자율주행 시스템은 여러 대의 카메라를 활용해 주변 환경을 인식합니다. 따라서 카메라 시점을 가로질러 움직이는 객체를 인식하려면 동일한 트랙 ID를 유지하는 것이 중요합니다. 우리는 3개의 전면 카메라로 캡처한 객체에 고유한 트랙 ID를 할당하는 주석이 달린 데이터 세트를 제공합니다. 전면 중앙에 있는 카메라의 화각(FOV)은 60도이고, 전면(왼쪽과 오른쪽)에 있는 두 카메라의 화각(FOV)은 120도입니다. 전면 3개의 카메라 모두 1920x1208의 해상도를 가지고 있습니다. MCMOT 데이터 세트의 카메라 이름은 다음과 같습니다.
  • camera_front_center_fov60
  • camera_front_left_fov120
  • camera_front_right_fov120

The tables below describe the annotation specifications. Table 1 and 2 show descriptions and rules for annotation types,
geometry and attributes.
TypeDescription
CarPassenger car, i.e., sedan or SUV, etc.
BusVehicle can carry more than 12 people
TruckAll types of trucks except tow trucks
Two wheelerAn object that runs on two wheels and a person who is with it, i.e., motorcycle, scooter, moped, bicycle, kick_scooter, stroller, etc.
PedestrianEvery person running, walking, sitting or standing.
Emergency carPolice car, ambulance, fire engine, tow truck, etc.
Misc.Other kinds of movable objects on the road
Table 1 : Type description for moving object
The annotation result consists of geometries and attributes which are defined as:
GroupSubgroupData
GeometryRear faceList of 4 vertices (rectangle)
Front faceList of 4 vertices (rectangle)
Left faceList of 4 vertices (trapezoid)
Right faceList of 4 vertices (trapezoid)
AttributesIDAssigned unique integer for identifying same objects
on overall frames and cameras
Visibility levelFully_visible - 100 %
Weakly_occluded/truncated - 60~99 %
Mostly_occluded/truncated - 30~59 %
Occluded/truncated - 0~29 %
Table 2 : Geometry and attributes description for moving object
We are interested in all types of visible objects such as cars, buses, trucks, two wheelers, pedestrians, emergency vehicles,
and other moving and stationary objects. Additionally, if the same object is observed from multiple cameras, the object is
given the same ID.

We assign the same annotation track ID to the same object of the data acquired from the three front cameras. The object with ID 35, a car is visible on all three cameras identifying the same object.
