- 该数据集是由吉林一号卫星创建,由分辨率为0.92米的高清全色图构成。 - 数据集使用长光官方开源的6个视频,每个视频选择约40个目标。 - 每个视频有500-753帧,持续20-30.12秒,帧速率为25fps,包括四个国家,五个城市,共248个物体。 - SV中有船舶、车辆、大型车辆和飞机四类对象,主要关注难以跟踪的小目标(车辆、大型车辆,占物体比例的90%)。 - 有关该数据集更详细的数据见“Deep Learning-Based Object Tracking in Satellite Videos: A Comprehensive Survey With a New Dataset”。 - 该数据集由西安电子科技大学IPIU实验室(智能感知与图像理解教育部重点实验室)于2021年7月完成。 -

NameDefinitionDependenceAUTO
Basic PropertiesCenter Point(CP)It represents the CP of the object bounding box.BBoxY
Movement Velocity(MV)It calculates the average velocity considering both the speed value and the direction in adjacent five frames (unit: pps)CPY
Object Size(OS)The largest value is selected from the height and width of the object bounding box.BBoxY
Frame State FlagsInvisible(INV)The object disappeared without any occluder or is too similar to its surroundings.MN
Normal Visible(NOR)The object is visible and found easily.MN
Occlusion(OCC)The object is in the shadow of the building or behind something.MN
Sequence AttributesBackground Change(BCH)The background of the tracked object has noticeable changes in color or texture.MN
Background Cluster(BCL)There are at least 10 frames that contain in the INV flag.INVY
Continuous Occlusion(CO)STO or LTO occur twice or more times in a sequence.STO, LTOY
Dense Similarity(DS)One or more similar objects exist around the tracked object in the range of 2.5 times OS.OSN
In-plane Rotation(IPR)The object has an in-plane rotation at an angle greater than or equal to 30°.MVY
Illumination Variation(IV)The object has noticeable changes in brightness or color.MN
Short-term Occlusion(STO)The sequence exists less than or equal to 50 conseccutive frames with OCC flag.OCCY
Long-term Occlusion(LTO)The sequence exists more than 50 consecutive frames with OCC flag.OCCY
Natural Disturbance(ND)The object's appearance is influenced by smog or sandy weather or blocked by clouds.MN
Slow Motion(SM)The moving speed of the tracked object is fewer than 2.2pps.MVY
