Raspi Flat field Images - Camera 04

Various single flat field images taken with different integrated lenses using a Raspberry Pi V2 camera at 30°C.The set contains 3669 flat field images per set in TIFF and JPEG format. Each image is approximattely16.2MB in size. Each JPEG image is 10.5MB. Each camera set is approximately 48GB in size.Images are captured in JPEG format with Bayer 10-bit raw data appended to the end of the file. This is extracted using DCRAW. Full research methodology for obtaining these images can be read in DOI:10.1016/j.diin.2019.02.002File structure:Each compressed folder contains one camera's data. This is then segregated into subfolders which contains six folders representing each discrete lens used in the data collection process. This is combined with six pinhole lenses that were also used in the data collection process. Each of these folders is divided into a JPEG folder which contains the raw output of the sensor and a TIFF folder which contains the DCRAW converted images. The TIFF folder is then broken down into the images and a seperate folder called Fingerprint which contains the 50 images used to construct a reference pattern for the camera with that discrete lens.The image is stored as a file name "BAYERYYYYMMDD-HHMMSS.tiff" where YYYY, MM, DD, HH, MM, SS represent standard ISO time stamp format.Example Tree for Raspi01/Raspi01.zip|-- Lens-01| |--JPEG| | |-- BAYER20170926-082159.jpg| | |-- BAYER20170926-082205.jpg| | | ...| | |-- BAYER20170926-084017.jpg| || |--TIFF| | | fingerprint| | | | -- BAYER20170926-083446.tiff| | | | -- BAYER20170926-083452.tiff| | | | ...| | | | -- BAYER20170926-084017.tiff| | || | |-- BAYER20170926-082159.tiff| | |-- BAYER20170926-082205.tiff| | | ...| | |-- BAYER20170926-083440.tiff||-- Lens-02|-- Lens-03|-- Lens-04|-- Lens-05|-- Lens-06|-- Pinhole-01|-- Pinhole-02|-- Pinhole-03|-- Pinhole-04|-- Pinhole-05|-- Pinhole-05

本数据集收录了由Raspberry Pi V2相机在不同集成镜头下，于30°C环境下拍摄的多种单平面场图像。该集合包含每个集3669张平面场图像，格式为TIFF和JPEG。每张图像大小约为16.2MB，而JPEG图像大小则为10.5MB。每个相机集的总容量约为48GB。图像以JPEG格式捕捉，并附加了Bayer 10位原始数据至文件末尾，可通过DCRAW提取。获取这些图像的完整研究方法可参阅DOI：10.1016/j.diin.2019.02.002。文件结构方面，每个压缩文件夹包含一个相机的数据，并进一步细分至子文件夹，其中包含六个文件夹，分别代表数据收集过程中使用的各个独立镜头。这些文件夹与六个用于数据收集过程的针孔镜头相结合。每个文件夹又被划分为JPEG文件夹，包含传感器的原始输出，以及TIFF文件夹，包含DCRAW转换后的图像。TIFF文件夹进一步细分为图像和一个名为Fingerprint的独立文件夹，其中包含用于构建该独立镜头相机参考模式的50张图像。图像存储为“BAYERYYYYMMDD-HHMMSS.tiff”文件名格式，其中YYYY、MM、DD、HH、MM、SS代表标准的ISO时间戳格式。以Raspi01/Raspi01.zip为例，示例树结构如下：|-- Lens-01| |--JPEG| | |-- BAYER20170926-082159.jpg| | |-- BAYER20170926-082205.jpg| | | ...| | |-- BAYER20170926-084017.jpg| || |--TIFF| | | fingerprint| | | | -- BAYER20170926-083446.tiff| | | | -- BAYER20170926-083452.tiff| | | | ...| | | | -- BAYER20170926-084017.tiff| | || | |-- BAYER20170926-082159.tiff| | |-- BAYER20170926-082205.tiff| | | ...| | |-- BAYER20170926-083440.tiff||-- Lens-02|-- Lens-03|-- Lens-04|-- Lens-05|-- Lens-06|-- Pinhole-01|-- Pinhole-02|-- Pinhole-03|-- Pinhole-04|-- Pinhole-05|-- Pinhole-05
