论文摘要
可见图像已被广泛用于运动估计。相比之下,热图像在运动估计中使用更具挑战性,因为它们通常具有较低的分辨率,质地较小和更多的噪声。在本文中,介绍了用于评估多光谱运动估计系统性能的新型数据集。所有序列都是从手持式多光谱设备记录的。它由标准的可见光相机,长波红外摄像头,RGB-D相机和惯性测量单元(IMU)组成。多光谱图像,包括完整传感器分辨率(640 x 480)的颜色和热图像,可从32Hz的标准和长波红外摄像头获得,并具有硬件同步。深度图像由Microsoft Kinect2捕获,并且可以为学习交叉模式立体匹配而有好处。对于轨迹评估,提供了从运动捕获系统获得的准确地面真相摄像头姿势。除了带有明亮照明的序列外,数据集还包含昏暗,变化和复杂的照明场景。完整的数据集,包括具有详细数据格式规格的原始数据和校准数据,可以公开使用。
Visible images have been widely used for motion estimation. Thermal images, in contrast, are more challenging to be used in motion estimation since they typically have lower resolution, less texture, and more noise. In this paper, a novel dataset for evaluating the performance of multi-spectral motion estimation systems is presented. All the sequences are recorded from a handheld multi-spectral device. It consists of a standard visible-light camera, a long-wave infrared camera, an RGB-D camera, and an inertial measurement unit (IMU). The multi-spectral images, including both color and thermal images in full sensor resolution (640 x 480), are obtained from a standard and a long-wave infrared camera at 32Hz with hardware-synchronization. The depth images are captured by a Microsoft Kinect2 and can have benefits for learning cross-modalities stereo matching. For trajectory evaluation, accurate ground-truth camera poses obtained from a motion capture system are provided. In addition to the sequences with bright illumination, the dataset also contains dim, varying, and complex illumination scenes. The full dataset, including raw data and calibration data with detailed data format specifications, is publicly available.
