Overview

we provide a new lifelong robotic vision dataset (“OpenLORIS-Object”) collected via RGB-D cameras mounted on mobile robots. The dataset embeds the challenges faced by a robot in the real-life application and provides new benchmarks for validating lifelong object recognition algorithms.

Data Collection

Data is obtained in the office and home environments. Several grounded robots mounted by Intel RealSense D435i and T265 camera is used for data collection. The D435i camera provides aligned color images and depth images, and IMU measurements. The T265 camera provides stereo fisheye images and aligned IMU measurements. In the 1st released dataset, we included the RGB and Depth images.

The robot is actively recording the videos of targeted objects under multiple illuminations, occlusions, camera-object distances/angles, and context information (clutters). We do include the common challenges that the robot is usually faced with. For example,

  • Illumination. In a real-world application, the illumination can vary significantly across time, e.g., day and night differences. We repeat the data collection under weak, normal, and strong lighting conditions, respectively. The task becomes challenging with lights to be very weak.
  • Occlusion. Occlusion happens when a part of an object is hidden by other objects, or only a portion of the object is visible in the field of view. Since distinctive characteristics of the object might be hidden, occlusion significantly increases the difficulty for recognition.
  • Object size. Small-size or elongated objects make the task challenging, like dry batteries or glue sticks.
  • Camera-object angles/distances. The angles of the cameras affect the attributes detected from the object.
  • Clutter. Clutter refers to the presence of other objects in the vicinity of the considered object. The simultaneous presence of multiple objects may interfere with the classification task.

Data Format

Our released dataset is a collection of 69 instances including 19 categories daily necessities objects under 7 scenes. For each instance, a 17 seconds video (at 30 fps) has been recorded with a Realsense D435i camera delivering ~ 500 RGB-D frames. 4 environment factors, each has 3 level changes, are considered explicitly in our dataset, including illumination, occlusion, clutter and actual pixel sizes of the object in the images. The defined three difficulty levels for each factor are shown below (thus, totally we have 12 subcategories w.r.t. the environment factors):

LevelIllunimationOcclusion(percentage)Object Pixel Size (pixels)Clutter
1Strong0%>200×200Simple
2Normal25%30×30−200×200Normal
3Weak50%<30×30Complex

For each instance in each level, we provided 260 samples. That is, for each instance, there are 3120 samples. The total images provided is around:

260 (samples/intance)× 69 (instance) × 4 (factors/level) × 3 (difficulty levels) = 215,280
