The top-level package 'opencv' is empty.  All the bits are in other
packages, e.g. on my system I have:
   # opkg list-installed | grep opencv
   libopencv-calib3d2.4 - 2.4.3-r2
   libopencv-contrib2.4 - 2.4.3-r2
   libopencv-core2.4 - 2.4.3-r2
   libopencv-features2d2.4 - 2.4.3-r2
   libopencv-flann2.4 - 2.4.3-r2
   libopencv-highgui2.4 - 2.4.3-r2
   libopencv-imgproc2.4 - 2.4.3-r2
   libopencv-legacy2.4 - 2.4.3-r2
   libopencv-ml2.4 - 2.4.3-r2
   libopencv-nonfree2.4 - 2.4.3-r2
   libopencv-objdetect2.4 - 2.4.3-r2
   libopencv-photo2.4 - 2.4.3-r2
   libopencv-video2.4 - 2.4.3-r2
   opencv-apps - 2.4.3-r2
   opencv-samples - 2.4.3-r0
   python-opencv - 2.4.3-r2

You shouldn't need to mention them all as they will come in by
dependencies.  Try adding 'opensv-samples opencv-apps' to your image.
