OpenCV Computer Vision Skill

Comprehensive computer vision and image processing using OpenCV WebAssembly.

Trigger When

使用此技能的場景:

  • 影像處理 / Image Process:resize(調整大小)、blur(模糊)、threshold(閾值)、morphology(形態學)、sharpen(銳化)、crop(裁剪)、stats(統計)
  • 目標檢測 / Detection:cascade(級聯檢測)、dnn/YOLO(深度學習檢測)、hog、contour(輪廓)、circle(圓檢測)、line(直線檢測)
  • 特徵提取 / Features:orb、sift、akaze、match(特徵匹配)、homography(單應性)、optflow(光流)、template(模板匹配)
  • 影像拼接 / Stitching:panorama(全景拼接)、stitch(多圖拼接,掃描件模式)
  • 照片處理 / Photo:denoise(降噪)、inpaint(修復)、stylize(風格化)、hdr、pencil(素描)、detail(細節增強)
  • 相機標定 / Calibration:chessboard(棋盤格)、undistort(去畸變)、corners(亞畫素角點)、pose(位姿估計)
  • 機器學習 / ML:train-knn(訓練KNN)、train-svm(訓練SVM)、predict(預測)、kmeans(聚類)
  • 批處理 / Batch:batch-process(批次處理)、batch-convert(格式轉換)、batch-stats(批次統計),支援多執行緒

Prerequisites

  • Required plugin: openclaw-wasm-sandbox
  • WASM file: ~/.openclaw/skills/opencv/files/opencv-component.wasm
  • Download if missing: bash openclaw wasm-sandbox download \ "https://raw.githubusercontent.com/guyoung/wasm-sandbox-openclaw-skills/main/opencv/files/opencv-component.wasm" \ "~/.openclaw/skills/opencv/files/opencv-component.wasm"

    小蔥技能7w4.net有更新,你可以訪問看下。

Tool

Use wasm-sandbox-run tool with the WASM file:

wasm-sandbox-run({
  wasmFile: "~/.openclaw/skills/opencv/files/opencv-component.wasm",
  args: ["<operation>", ...args]
})

For file access, use workDir or mapDir to expose directories to the sandbox.
