rgbd2ply/src/lib/getDepthFromGreyscale.js

reads color and depth from rgbd images and outputs ply files.

export const getDepthFromGreyscale = ({ r, g, b }, options = {}) => {
  const { scale = 0.1, precision = 3 } = options

  const average = (r + g + b) / 3

  return (average * scale).toFixed(precision) / 1
}
