開放的攝影測量標準(OPF)是一種新的數據格式旨在改善存儲、交換和利益相關者之間的合作在攝影測量數據和產品。Pix4D的年代最新的時事通訊,無人機映射和攝影測量解決方案提供商宣布它已經開發了一個新的行業標準交換攝影測量的標準稱為開放攝影測量標準(OPF)。標準的完全開放和自由,使來自不同供應商的產品之間的數據協作。標準規範和Python庫的標準開發滿足市場需求的標準化和開放格式存儲和共享攝影測量數據。沒有這樣的一個標準,利益相關者之間的合作和不同軟件程序是很困難的。Pix4D國家標準非專有、開放、靈活、可擴展的。一個規範的標準由基於簡單的JSON結構。一個項目文件函數作為一個容器與其他相關文件。本規範文檔可以在GitHub Python庫閱讀,寫作,和操作消息對象。目前,標準兼容PIX4Dmatic Pix4D無人機和地麵攝影測量軟件映射。 This means the software enables the import and export of OPF objects. This capability will be extended to other company products in the future. Vendor-specific extensions can be proposed through the standard’s GitHub space. This space is also meant for feedback, exchange for user experiences, and collaboration on the Python tool. Potential user base The OPF standard is meant to be used by researchers, academics, and professionals working with digital images and are looking for a standardized way to manage and share photogrammetry projects. The main benefits for researchers are better data access and avoiding compatibility issues when working with data from different vendors. They will also spend less converting data and thus save time. OPF stores all data related to a reconstructed 3D model made with photogrammetry, including both inputs and outputs of the photogrammetry model such as the cameras used, their parameters, coordinate reference system and control points. The output data includes info about the camera calibration and the dense reconstructed point cloud. Community feedback When announcing this new standard, Pix4D asked for feedback on the initiative. In an online discussion on the website of OpenDroneMap (ODM), some additional information was given by a Pix4D representative following the announcement of the new OPF standard and subsequent feedback from the ODM community. OpenDroneMap is an open-source photogrammetry toolkit to process aerial imagery into maps and 3D models. This community could be a potential user community of the new standard. The Pix4D representative stated the publication of the specification is only the first step, and that it will be extended in the future so that for example added support for other features will be added. Currently the company is working on OPF extensions such as processing areas, depth maps which are computed or from depth sensors, and planes. It will be interesting to see how the standard itself will be developed further, and how the different user communities can participate in this process.
