资源简介:
The target in this dataset is the Apogee Kick Motor (AKM) (similar to the STAR 24 motor), a radially symmetric and textureless space object. The motor dimensions are a diameter of 24.5 inches (0.62 m) and a length of 42.0 inches (1.0668 m). The dataset contains 10000 images generated with a blender under lighting conditions similar to the orbital environment with an image size of 1024 x 1024 pixels rendered using a pin-hole camera model having a field of view of 55 degrees. The target positions are obtained from a uniform random distribution between 1m and 10 m, and orientations are obtained from a uniform random distribution. The groundtruth.csv contains the pose labels. filename - filename of the image. Tx, Ty, Tz - represents the location of the target in the Camera coordinate frame Qx, Qy, Qz, Qw - quaternion representation of target orientation in camera coordinate frame K.txt - contains the Camera intrinsic matrix. @inproceedings{rathinam2022pose,

本数据集的标注目标为远地点推进发动机(Apogee Kick Motor, AKM),其性能参数与STAR 24发动机近似,属于径向对称且无纹理的航天目标。该发动机的尺寸参数为:直径24.5英寸(0.62米),长度42.0英寸(1.0668米)。本数据集包含10000张由Blender渲染生成的图像,渲染时采用模拟轨道环境的光照条件,图像分辨率为1024×1024像素,使用针孔相机模型进行渲染,相机视场角为55度。目标的空间位置服从1米至10米区间内的均匀随机分布,目标朝向服从均匀随机分布。groundtruth.csv 文件包含位姿标注信息,各字段说明如下:
- filename:对应图像的文件名;
- Tx、Ty、Tz:代表目标在相机坐标系下的三维位置;
- Qx、Qy、Qz、Qw:代表目标在相机坐标系下朝向的四元数表示。
K.txt 文件包含相机内参矩阵。
