EANJ_LZH_62: Low-Resolution Visual Record of a Jade Object (Public Preview)
收藏资源简介：
1. Dataset Context This dataset forms part of a systematic digital visual archiving project.It documents multi-angle, low-resolution image data of a single jade object (EANJ_LZH_62) and is released as the public preview layer within a tiered data structure. 2. Research Purpose This dataset was generated through standardized image acquisition and organization to provide independently verifiable baseline visual data, supporting researchers in conducting the following activities within their own methodological frameworks: Morphological comparative studies Teaching and illustrative use Image-based, non-invasive analysis The low-resolution images are intended solely for public preview purposes.The original high-resolution image data (approximately 42 megapixels per image) are published as a separate dataset (Record B) under restricted access. Access requests should be submitted via the following DOI:https://doi.org/10.5281/zenodo.20029574 3. Data Description 3.1 Object Information Approximate reference values (non-precision measurements): Length: 6.9 cm Width: 2.9 cm Thickness: 1.4 cm Weight: 53 g Note: The above measurements are reference values derived from image-based observation and do not constitute precise metrological results. 3.2 Image Content The low-resolution public preview includes four representative images selected for structural identification and basic visual reference: Overall views EANJ_LZH_62_OVERALL_A EANJ_LZH_62_OVERALL_C Macro views EANJ_LZH_62_MACRO_D EANJ_LZH_62_MACRO_G This public preview represents a subset of representative images.The complete multi-angle high-resolution dataset (Record B) contains a broader range of viewing angles and more detailed visual documentation. 3.3 Imaging Method Equipment: Full-frame digital camera with a 90 mm macro lens Format: Captured in RAW format; converted to JPEG for release Lighting: Controlled lighting environment Background: Neutral background Physical intervention: None performed Post-processing: Limited to global exposure and white balance adjustment 4. Data Access & Structure This dataset follows a tiered publication structure: Record A: Low-resolution public preview (this record) Record B: High-resolution original images (restricted access) This structure distinguishes the public presentation layer from the research-grade data access layer. 5. Usage & Licensing This dataset is intended for: Academic research Teaching purposes Non-interpretive visual and comparative analysis Any uses beyond the above—including commercial applications, redistribution, or dissemination in non-academic contexts—require prior authorization. 6. Notes on Interpretation This dataset provides only visual information directly observable in the images and contains no interpretive, attributive, or historical assessments. 7. Access Information The complete high-resolution image dataset (Record B) has been published as an independent dataset under restricted access.Access requests should be submitted via the following Zenodo DOI:https://doi.org/10.5281/zenodo.20029574
