如何将多个CSV文件从目录导出到另一个CSV文件表

Question

目录中有多个文件 汽车 Bus.Csv

我有用于捕获Csv文件并将其加载到新Csv文件中的脚本。但是我想读取这些文件并加载到新的Csv文件中。

第1张：Cars.Csv数据

第2张：Bus.Csv数据

脚本：

  document.getElementById('status').innerHTML = 'OpenCV.js is ready.';
  let video = document.getElementById('videoInput');
  let src = new cv.Mat(video.height, video.width, cv.CV_8UC4);
  let dst = new cv.Mat(video.height, video.width, cv.CV_8UC4);
  let gray = new cv.Mat();
  let cap = new cv.VideoCapture(video);
  let faces = new cv.RectVector();
  let classifier = new cv.CascadeClassifier();

  // load pre-trained classifiers
  classifier.load('haarcascade_frontalface_default.xml');

  const FPS = 30;
  function processVideo() {
      try {
          if (!streaming) {
              // clean and stop.
              src.delete();
              dst.delete();
              gray.delete();
              faces.delete();
              classifier.delete();
              return;
          }
          let begin = Date.now();
          // start processing.
          cap.read(src);
          src.copyTo(dst);
          cv.cvtColor(dst, gray, cv.COLOR_RGBA2GRAY, 0);
          // detect faces.
          classifier.detectMultiScale(gray, faces, 1.1, 3, 0);
          // draw faces.
          for (let i = 0; i < faces.size(); ++i) {
              let face = faces.get(i);
              let point1 = new cv.Point(face.x, face.y);
              let point2 = new cv.Point(face.x + face.width, face.y + face.height);
              cv.rectangle(dst, point1, point2, [255, 0, 0, 255]);
          }
          cv.imshow('canvasOutput', dst);
          // schedule the next one.
          let delay = 1000/FPS - (Date.now() - begin);
          setTimeout(processVideo, delay);
      } catch (err) {
          utils.printError(err);
      }
  };

  // schedule the first one.
  setTimeout(processVideo, 0);
}
