网袋相机是一款为网球训练、对抗比赛和赛后复盘设计的 iPhone 与 Apple Watch 应用。将一台支持双摄录制的 iPhone 固定在球网中央,就能同时记录球场两侧,保留双方发球、接发球、底线相持和上网击球画面。 ### 一台 iPhone,同时记录双方 前置与后置摄像头同步录制,把球网两侧画面放在同一条时间线上。不必准备两台相机,也不用在多个视频之间反复寻找同一回合。 ### Apple Watch 远程控制与比赛记分 手机固定好后,可以通过 Apple Watch 开始或结束录制。比赛模式支持设置双方名称、站位、先发球方和计分规则,并在手表上记录双方得分。手机与手表会同步当前比分、发球方和比赛状态。 ### 没有手表记分,也能整理逐分索引 如果比赛已经录完但没有逐分记分,网袋相机可以根据击球声音和画面运动生成候选回合。你可以逐段播放,并确认我方得分、对方得分或删除误检。应用不会在缺少依据时替你猜测得分方。 ### 逐分复盘与技术统计 每一分都可以定位播放,并修正得分方和得分类型。应用会根据记分记录整理当前比分、发球表现、接发球表现、Winner、非受迫性失误、ACE、双误和关键分等比赛数据。 ### 智能剪辑与多比例导出 从完整比赛录像中选择需要的回合,生成更适合训练复盘或分享的成片。导出时可以添加比分字幕和双方数据统计,并根据使用场景选择不同画面比例。完整母带会继续保留,不会被智能剪辑覆盖。 ### 独立裁判记分 不需要录像时,也可以关闭相机预览,只使用手机完成比赛记分和技术统计。比赛结束后可生成 4:5 技术统计海报,方便保存和分享。 ### 本地管理,记录由你掌控 比赛录像、比分和统计数据主要保存在设备本地。你可以分别管理视频缓存和比分记录,删除测试比赛时不会误删关联录像。 适合以下场景: - 网球训练录像与动作复盘 - 单打或双打比赛记录 - Apple Watch 场边遥控和辅助记分 - 教练、家长或裁判记录比分与技术统计 - 从完整比赛中整理逐分视频和精彩回合 说明:自动分析用于生成待确认的回合时间索引,不提供专业鹰眼判罚,也不会自动判断每一分的胜负方。双摄录制需要设备支持 Apple 多摄像头同时采集能力。 使用条款(Apple 标准 EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
