The TRICLOBS Dynamic Multiband Image Dataset

The TRICLOBS dynamic multiband image dataset contains registered visual (400-700 nm) , near-infrared (NIR, 700-1000 nm) and longwave infrared (LWIR, 8-14 µm) motion sequences. This dataset is primarily intended for the development and evaluation of image fusion and color mapping algorithms for (military and civilian) surveillance applications. The imagery was collected during several field trials with the TRICLOBS (TRI-band Color Low-light OBServation) all-day all-weather surveillance system. The TRICLOBS system registers a scene in the Visual, NIR and LWIR part of the electromagnetic spectrum using three optically aligned sensors (two digital image intensifiers and an uncooled longwave infrared microbolometer). The three sensor signals are mapped to the three individual RGB color channels, digitized and stored as uncompressed RGB (false) color frames. The TRICLOBS image dataset contains 16 motion sequences representing different military and civilian surveillance scenarios and registered at three different locations. It is expected that the dataset will be useful for the development and evaluation of (both static and dynamic) image fusion and color mapping algorithms. To enable the development or realistic color remapping procedures, the dataset also contains color photographs of each of the three scenes. The color statistics derived from these photographs may be used to define color mappings that give the multiband imagery a realistic color appearance. Some color remapped examples are provides as MP4 movies.<br>TRICLOBS动态多波段图像数据集包含配准后的可见光（Visual, 400-700 nm）、近红外（Near-Infrared, NIR, 700-1000 nm）与长波红外（Longwave Infrared, LWIR, 8-14 µm）运动序列。本数据集主要面向军用与民用监视应用场景下的图像融合及色彩映射算法的研发与评估工作。该数据集的影像采集自搭载TRICLOBS（TRI-band Color Low-light OBServation，三波段彩色微光观测）全天候全天时监视系统的多场野外试验。TRICLOBS系统通过三台光学对齐的传感器（两台数字图像增强器与一台非制冷长波红外微测辐射热计），对电磁光谱中的可见光、近红外与长波红外波段的场景完成配准。随后将三路传感器信号映射至独立的RGB（红、绿、蓝）三色彩通道，经数字化处理后以未压缩的RGB伪彩色帧格式存储。TRICLOBS图像数据集包含16段运动序列，涵盖不同的军用与民用监视场景，且在三个不同点位完成配准。本数据集可用于静态与动态图像融合及色彩映射算法的研发与评估。为支持逼真色彩重映射流程的研发，数据集还包含三个观测场景各自的彩色照片。从这些彩色照片中提取的色彩统计数据，可用于生成可使多波段影像呈现逼真色彩效果的色彩映射方案。部分色彩重映射后的示例片段以MP4视频格式提供。
