    我需要一套完整的方案,用实时视频流监控一颗白球的运动,并把它每完成一圈时的速度(以毫秒计)写入数据库。只做实时监控,不必录制或回放。 核心工作内容 - 通过摄像头获取实时画面,自动识别并追踪白球位置与轨迹 - 在白球每绕行一圈时计算圈速,并立即写入数据库 - 设计并搭建适合此场景的数据库(你可以自由选择关系型、时序或其他类型,理由充分即可) 技术方向 我倾向于看到 Python + OpenCV 这样的常用计算机视觉方案,但如果你有更高效的框架也欢迎提出。数据库部分只要能稳定写入并便于后续查询统计即可,MySQL、PostgreSQL、InfluxDB 等都可讨论。 交付物 1. 可直接运行的源代码与依赖说明 2. 数据库结构及初始化脚本 3. 简洁的使用文档:如何接入摄像头、启动服务、查看和导出圈速数据 4. 简单演示视频或在线演示链接,证明系统能在实时流中正确记录圈速 1:白色球体扔出时候顺时针,逆时针 2:从扔出球体开始位置,每一圈的速度是多少,ms 3:白色球体扔出去时候对应的数字是多少,每一圈到白色球体开始位置对应的数字是多少 验收标准 - 白球在摄像头视野内连续运动时,系统能稳定检测并记录至少 95% 的圈速事件 - 数据库内每条记录包括:圈序号、圈速(ms)、时间戳 - 实时延迟控制在 500 ms 以内(从圈完成到数据入库) 请在回复中说明你推荐的技术栈、预计开发周期,以及需要我提前配合的硬件或环境信息。

    I’m looking for a reliable person who can pick up my business line whenever I’m unavailable and handle general-inquiry calls in a courteous, professional manner. Expect no more than one call a day on average, so this is truly light-volume work; nevertheless, each caller must feel they’ve reached a polished, well-run office. *I need you to act as a credible reference for future employers Here’s what I need from you: • Answer the call using my templates (I’ll provide the exact wording). • Note the caller’s name, contact details, and the reason for calling. • Email or text me the call summary right after you hang up. Because these are general inquiries, you won’t need deep industry knowledge; a clear speaking voice, at...

    ...device. Here is what I need from you: • A well-structured MongoDB schema and any necessary data-migration scripts. • Express/Node controllers that expose secure, well-documented REST endpoints. • A React front-end that consumes those endpoints and follows modern component patterns. • Basic authentication and session handling where appropriate. • Code that is easy for another developer to pick up later—clear comments, sensible folder structure, and concise README. I’m committed to the MERN stack, yet if you see a compelling reason to borrow concepts from MEAN or even a Django + React setup, tell me why in your proposal; I’m open to ideas that improve performance or maintainability. To be considered, send me a detailed projec...

    I need a visually striking yet rock-solid website dedicated to booking and managing tour packages. The core of the site is a seamless reservation flow: visitors browse, choose a package, pick dates, and pay—everything handled in one intuitive interface with real-time availability. On every package page I want three engagement drivers baked in from the start: • Customer reviews that can be rated, sorted, and moderated • A clear, expandable itinerary section so travelers see day-by-day details • A high-impact photo gallery that loads fast and looks great on mobile Design has to be fully responsive, fast, and SEO friendly. Clean code, easy-to-update CMS (WordPress with WooCommerce, Laravel, or a comparable framework—open to your recommendation) and secu...

    I need a streamlined, reliable automation layer for my BIJILITRA operation. Right now our day-to-day work still relies on a mix of spreadsheets, a small SQL store, and a couple of home-grown...effort as possible. Your solution should: • Plug into (or sensibly replace) our existing Excel and SQL assets without disrupting live data. • Include clear, commented code or low-code components that my team can maintain. • Ship with concise user documentation and a brief hand-off session so we understand exactly how to run, monitor, and expand the automation. I’m open on language and toolset; pick what will deliver stable, real-time processing, easy scheduling, and insightful data analysis. Please outline your proposed approach, key milestones, and any relevant past...

    My business receives a small yet steady flow of customer-service calls each week and I need those conversations handled smoothly from Ho Chi Minh City. You will pick up the phone in both English and Vietnamese, help the caller resolve simple queries when possible, then record concise notes in a shared call log so I can track every interaction. For now the workload is about one hour spread across the week, but it will grow as the venture scales, so I’m counting on someone who can work independently and stay organised without constant oversight. Core duties • Answer customer-service inquiries promptly in English and Vietnamese • Take clear, timestamped messages and enter them in the call log • Schedule follow-up appointments directly into my online calenda...

The Figma link, assets, and a brief style guide will be shared after we start.

    ...matching 3D environments, get my approval on them, and then capture exactly 30 high-quality screenshots from specific perspectives. How the workflow will work: I will give you a scene description (like a futuristic city or a fantasy tavern). You will find 2 or 3 free 3D assets or environments online (using platforms like Sketchfab, Blender, or other free repositories) and send them to me. Once I pick the one that fits my vision, you will set up the camera angles based on my directions and take the screenshots. Most of the shots will be at eye level or slightly above eye level. To show you what I mean, here is a sample breakdown of how a single environment will require a sequence of 3 to 4 distinct angles: Environment 1: The Sci-Fi City Shot 1 (Bird’s-Eye View): A hig...
