开源Spaghetti Detective AI software detects failed prints through webcam

With the majority of the world home-bound due to the2019冠状病毒病暴发,开源社区似乎还活着,并以其3D打印的最新礼物踢开了:一种自动暂停未能打印的AI软件。意大利面条侦探(TSD) utilizes the webcam of a printer or home computer to detect when a print job has gone wrong and started extruding ‘spaghetti’, interrupting the process and alerting the user through an email or text message.

如果在一台3D打印机上使用,则可以免费下载TSD,检查一次打印的进度。如果需要,用户可以选择一次支付一项一次观察多台3D打印机的专业服务,从而使帧速率高达每秒25。雷电竞app下载Pro服务的起价为每月4美元,额外的打印机(最多五张)被添加到阿森纳,价格为2美元。

3D打印的深度学习

According to Kenneth Jiang, the lead software engineer behind TSD, the AI is built on a deep learning algorithm by the name ofYOLO。TSD团队最初装箱了意大利面条已被挤出的图像贴片,有效地数据标记了图像。这些失败印刷品的图像在其婴儿期间被喂入Yolo算法,并在打印失败检测中训练它。经过许多循环,该算法最终学会了自身检测图像中的意大利面条。现在,它在图像上显示框,其中认为发生了失败的打印,并说明了它的信心水平。

历史上,TSD的不准确率为6.9%,这意味着它错过了失败或平均每100次打印的误报6.9倍。TSD团队正在努力保持未来几个月的不准确率仅2%

In a recentreddit帖子on r/3Dprinting, an online community of 3D makers, one user shared their experience of TSD going above and beyond the call of duty, unintentionally detecting a failed print on a printer operating in the background of the webcam’s vision. The post just goes to show the potency of the AI, despite it still being a work in progress. With ongoing refinement on the project, the TSD team expects the software to graduate from just the hobbyist maker community and be adopted in an industrial setting. They believe it could be extremely useful to print farms and larger prototyping businesses, automating a portion of the workflow.

TSD是3D打印社区的众多开源贡献之一。在过去的几年中,制造商一直从中受益八普林, a software platform that允许用户远程控制和监视打印作业从他们的设备。位于英国的3D文件市场MyMiniFactory以前还推出了单击&打印插件,可与八普林平台一起使用。The plugin starts a print job straight from an STL file based on predetermined print parameters, allowing novice users to skip the file preparation stage of the 3D printing process.
