title: how to create a rgbd Image from numpy rgb array and depth array?
body: <p>I have a numpy array which is the color image &quot;img&quot; of shape (height, width, 3), and also a depth numpy array of shape (height, width).
  And I want to create an RGBD image and display it, for which I'm doing the following:</p>
  <pre><code>o3d.geometry.RGBDImage.create_from_color_and_depth(img, depth)
  </code></pre>
  <p>But I'm getting the error:</p>
  <pre><code>TypeError: create_from_color_and_depth(): incompatible function arguments. The following argument types are supported:
      1. (color: open3d.open3d_pybind.geometry.Image, depth: open3d.open3d_pybind.geometry.Image, depth_scale: float = 1000.0, depth_trunc: float = 3.0, convert_rgb_to_intensity: bool = True) -&gt; open3d.open3d_pybind.geometry.RGBDImage
  
  </code></pre>
  <p>How to fix this? If it requires an Image type, then how to convert the numpy array to an Image type?</p>
  <p>Even when I pass in the numpy arrays into the o3d.geometry.Image constructors like so:</p>
  <pre><code>o3d.geometry.RGBDImage.create_from_color_and_depth(o3d.geometry.Image(img), o3d.geometry.Image(depth))
  </code></pre>
  <p>I get the error:</p>
  <pre><code>TypeError: create_from_color_and_depth(): incompatible function arguments. The following argument types are supported:
      1. (color: open3d.open3d_pybind.geometry.Image, depth: open3d.open3d_pybind.geometry.Image, depth_scale: float = 1000.0, depth_trunc: float = 3.0, convert_rgb_to_intensity: bool = True) -&gt; open3d.open3d_pybind.geometry.RGBDImage
  
  </code></pre>
  <p>How to fix this and create the RGBD image from the rgb numpy array and the depth numpy array?</p>
