openni_wrapper::DeviceXtionPro::getCurrentImage returns null pointer?

描述

boost::shared_ptr<openni_wrapper::Image> 
openni_wrapper::DeviceXtionPro::getCurrentImage (boost::shared_ptr<xn::ImageMetaData>) const throw ()
{
  return (boost::shared_ptr<Image> (reinterpret_cast<Image*> (0)));
}

boost::shared_ptr<openni_wrapper::Image> 
openni_wrapper::DevicePrimesense::getCurrentImage (boost::shared_ptr<xn::ImageMetaData> image_data) const throw ()
{
  return (boost::shared_ptr<openni_wrapper::Image> (new ImageYUV422 (image_data)));
}

研究方向

The issue shows that `openni wrapper::DeviceXtionPro::getCurrentImage` returns a null pointer, while the analogous function in `DevicePrimesense` returns a proper image. The fix should modify `getCurrentImage` in the Xtion Pro device class to return an actual image, likely `ImageYUV422` if the color format matches, otherwise researching the correct format. The relevant files are in `openni wrapper/src/`; see the implementation in `openni device primesense.cpp` as a reference. Check for any tests or changes in the repository since this issue was filed in 2014.
