Abstract

Premise

Field images are important sources of information for research in the natural sciences. However, images that lack photogrammetric scale bars, including most iNaturalist observations, cannot yield accurate trait measurements. We introduce FieldPrism, a novel system of photogrammetric markers, QR codes, and software to automate the curation of snapshot vouchers.

Methods and Results

Our photogrammetric background templates (FieldSheets) increase the utility of field images by providing machine-readable scale bars and photogrammetric reference points to automatically correct image distortion and calculate a pixel-to-metric conversion ratio. Users can generate a QR code flipbook derived from a specimen identifier naming hierarchy, enabling machine-readable specimen identification for automatic file renaming. We also developed FieldStation, a Raspberry Pi–based mobile imaging apparatus that records images, GPS location, and metadata redundantly on up to four USB storage devices and can be monitored and controlled from any Wi-Fi connected device.

Conclusions

FieldPrism is a flexible software tool designed to standardize and improve the utility of images captured in the field. When paired with the optional FieldStation, researchers can create a self-contained mobile imaging apparatus for quantitative trait data collection.

FieldPrism：一个使用摄影测量标记和二维码从现场图像创建快照凭证的系统。

前提：野外图像是自然科学研究的重要信息来源。然而，缺乏摄影测量比例尺的图像，包括大多数自然学家的观察，无法产生准确的特征测量。我们介绍了FieldPrism，这是一个由摄影测量标记、二维码和软件组成的新型系统，用于自动管理快照凭证。方法和结果：我们的摄影测量背景模板（FieldSheets）通过提供机器可读的比例尺和摄影测量参考点来自动校正图像失真并计算像素与度量的转换率，从而提高了现场图像的实用性。用户可以从标本标识符命名层次结构中生成二维码挂图，从而实现机器可读的标本识别，实现文件自动重命名。我们还开发了FieldStation，这是一款基于Raspberry Pi的移动成像设备，可在多达四个USB存储设备上冗余记录图像、GPS位置和元数据，并可通过任何Wi-Fi连接设备进行监控。结论：FieldPrism是一种灵活的软件工具，旨在标准化和提高现场拍摄图像的实用性。当与可选的FieldStation配对时，研究人员可以创建一个独立的移动成像设备，用于定量特征数据收集。

期刊介绍： Applications in Plant Sciences (APPS) is a monthly, peer-reviewed, open access journal promoting the rapid dissemination of newly developed, innovative tools and protocols in all areas of the plant sciences, including genetics, structure, function, development, evolution, systematics, and ecology. Given the rapid progress today in technology and its application in the plant sciences, the goal of APPS is to foster communication within the plant science community to advance scientific research. APPS is a publication of the Botanical Society of America, originating in 2009 as the American Journal of Botany''s online-only section, AJB Primer Notes & Protocols in the Plant Sciences. APPS publishes the following types of articles: (1) Protocol Notes describe new methods and technological advancements; (2) Genomic Resources Articles characterize the development and demonstrate the usefulness of newly developed genomic resources, including transcriptomes; (3) Software Notes detail new software applications; (4) Application Articles illustrate the application of a new protocol, method, or software application within the context of a larger study; (5) Review Articles evaluate available techniques, methods, or protocols; (6) Primer Notes report novel genetic markers with evidence of wide applicability.
