Hi everyone,

So im trying to get a data from a local webpage, generated from esp32-cam module, it looks like this

ESP32-CAM
ESP32-CAM1920×946 145 KB

And what im trying to do is getting the data inside the red box at the right bottom, inside the box is the color value data. For the value its located inside the web page script

  //ANN:8
  let M00Array = [0,];
  let orig = new cv.Mat();
  let mask = new cv.Mat();
  let mask1 = new cv.Mat();
  let mask2 = new cv.Mat();
  let contours = new cv.MatVector();
  let hierarchy = new cv.Mat();
  let rgbaPlanes = new cv.MatVector();
    
  let color = new cv.Scalar(0,0,0);

  clear_canvas();


    
  orig = cv.imread(ShowImage);
  cv.split(orig,rgbaPlanes);  //SPLIT
  let BP = rgbaPlanes.get(2);  // SELECTED COLOR PLANE
  let GP = rgbaPlanes.get(1);
  let RP = rgbaPlanes.get(0);
  cv.merge(rgbaPlanes,orig);
   
    
              //   BLK    BLU   GRN   RED
  let row = Y_PROBE //180//275 //225 //150 //130    
  let col = X_PROBE //100//10 //100 //200 //300
  drawColRowText(acols,arows);


  console.log("ISCONTINUOUS = " + orig.isContinuous());

  //ANN:9C
  R = src.data[row * src.cols * src.channels() + col * src.channels()];
  G = src.data[row * src.cols * src.channels() + col * src.channels() + 1];
  B = src.data[row * src.cols * src.channels() + col * src.channels() + 2];
  A = src.data[row * src.cols * src.channels() + col * src.channels() + 3];
  console.log("RDATA = " + R);
  console.log("GDATA = " + G);
  console.log("BDATA = " + B);
  console.log("ADATA = " + A);

  drawRGB_PROBE_Text();

The data are on variable BP, Gp, and RP, so how can i get the data?
