姿勢推定
合同会社中江技研
中江広悟
??紹介
? 名前:中江広悟(なかえひろのり)
? エンジニア歴10年くらい?
? やってきたこと
? メタバース
? ブレインテック(IoT)
? Web/スマホ
? Winアプリケーションとか
? 昨年から兵庫県川?市で
?分の会社始めました
最近ハマってること(その1):ガジェット集め
エレコム メカニカルキーボード Leggero 有線
赤軸 グレー TK-MC50UKLGY/EC
高コスパ。
10キーはいる気がしたりしなかったり。
エレコム USB マウス 有線
トラックボール 大玉 8ボタン チルト機能
高コスパ。時代はトラックボール。
最近いいなと思っている趣味:温泉旅館巡り
?温泉旅館は五感とロマンである? by 技術顧問
最近ハマりつつ
ある開発??
(本題)
姿勢推定
(AI)
テニスしてました。
最近はデブです。
颁厂痴を?てみる
なんの役に?つの?
利?例1:
VTUBER
https://digital-standard.com/tdpt_lp/
利?例2:解析:既に医学論?での利?実績あり
? スマートフォンアプリケーションTDPT-GTを?いたモーションキャプチャによる正常
圧?頭症とパーキンソン病における歩?時の上下肢の動きの変動評価
https://www.mdpi.com/1424-8220/23/22/9263
? ??知能による病的歩?の識別:iOSアプリケーション(TDPT-GT)によって取得され
たマーカーレスモーションキャプチャ歩?データの解析
https://www.mdpi.com/1424-8220/23/13/6217
? 深層学習スマートフォンアプリで推定された三次元座標から変換された体軸投影平?
上の定量的歩?特徴評価
https://www.mdpi.com/1424-8220/23/2/617
利?例3:
ダンスゲーム
https://p.eagate.573.jp/game/around/1st/howto/index.html
コナミアミューズメント
DANCE aROUND
姿勢推定ってどうやってん
の?
? 超ざっくり?うと、画像を??された推論モデル
(AI)がその特徴を解析して、その画像に映る?
の各関節の x, y, (z) 座標を出?している
? 学習データを使って任意の期間学習させることで
基本的には精度が上がる
? 学習データが出鱈?だと、出鱈?な推論モデルし
か?まれない
? 学習データ命!
? モデルの構造はいろいろある
COCO
CHALLENGE
https://paperswithcode.com/sota/pose-estimation-on-coco-test-dev
モデル選定の観点
? 軽さ(推論するのに必要な計算量)
? CPU or GPU
? 正確さ
? 外乱への強さ
? 複数?数対応か
? 規格
? ONNX(汎?。Win/Mac/iOS/Linux/…)
? TF(Google系?)
? Core ML ( apple )
? etc
軽ければ??
? スマホで推論
? Jetson Nano で推論
? ?般的な事務?の Windows / Mac でも推論
正確でないと
意味ないじゃん。
外乱に弱いと..
? 背景に?が?えたりしていると?と
誤認識して推論が乱れる
複数?数に対応していれば..
MMPose RTMO
https://github.com/open-mmlab/mmpose?tab=readme-ov-file
規格や推論エンジンのバリエーション
? 推論?体を爆速化
? 既存のシステム上で推論モデルを動作させたり
? 精度が上がったり、下がったり。。。
これらのことを意識して、
- 推論モデルを選択、
- 学習
- 必要に応じてモデルをエクスポート、
- チューニング
- 検証
を?う。すべて奥が深そう。。(詳しくないw)
そう、それはつまり、
奥の深い開発だ(えw)!
利??途を考えるのも楽しい
? テニス
? ゴルフ
? 防犯
? etc
可能性は無限?!
そんな開発を今後はどしどしやって参ります。
「それ間違っているよ!」とか、「こうしたらいいんじゃん?」とか、
「何それ??い、もっと聞かせて」とかあれば、お気軽にお声がけ下さい!
Twitter で DM でもOKです!
@hironori_yan
中江技研では、この他にも多様なシステム開発案件があったりなかったりしてお
ります。
システム開発のご依頼は勿論、開発パートナーも探しており、少しでもご興味あ
る?はこちらもお気軽にお声がけ下さい。
テニスしましょう、とか、開発の話しながら飲みましょうとかでもOKです!
以上、ありがとうございました。
