StarLocator 是什么 | WHAT IS STARLOCATOR
StarLocator是一款天文定位应用,主要基于一种已经应用了数个世纪的航海导航技术。该应用使用夜空照片及其精确拍摄时间为源数据,计算照片拍摄地在地球上的大致位置。该过程类似以相机对图中的天体高度角进行测量代替17世纪以来的水手使用六分仪的测量,与占星术、玄学和心灵感应无关。
StarLocator is a celestial positioning application mainly based on a maritime navigation technique that has been applied for centuries. In this app, a photo of night sky and the exact time when it was taken were used as source information to calculate the rough position of the photo taker was on the earth. The process is quite like using the camera as a sextant to measure the elevation of celestial bodies in the image just as sailors did since 17th century, and there is NOTHING to do with astrology, metaphysics and telepathy.
- ✨自动识星:通过拍摄的星空照片,自动识别照片中的星星,无需手动辨识。
- 😀交互简单:标星、标铅垂线、设置拍摄时间,然后就是点击按钮的事了,熟练掌握后整个过程不到5分钟。原本的耗时步骤,如查询天体天文数据,已被API和按钮所实现。
- 🔒隐私友好:项目采用前后端分离架构,服务器后端只在核心计算时获取必要信息,并在结束计算后删除。
- 🎯精度良好:我们在各个模块中采用了强稳健性的算法,对环境噪声、标记误差有良好的抗噪能力,误差通常可稳定在30km以下。
- ✅完全开源:我们使用AGPL v3开源,目的是为尽可能地使该方法透明,同时欢迎社区共建。
- ✨Automatic star recognition: By capturing starry sky photos, stars in the photos can be automatically recognized without the need for manual recognition.
- 😀Simple interaction: Marking stars and plumblines, setting the time and then simply click a button. Can finish within 5 minutes when familiar. All time-consuming steps, like searching for data of celestial bodies, have been achieved with API and buttons.
- 🔒Privacy friendly: The project adopts a front-end and back-end separation architecture, where the server backend only retrieves necessary information during core computing and deletes it after the computation is completed.
- 🎯Good accuracy: We applied robust algorithms in modules, making it resilient to environmental noises and marking errors. The error can usually be limited to 30km.
- ✅Fully open sourced: AGPL v3 open source protocol adopted. Aiming to make the approach as transparent as possible and to welcome community contributions.
