 ERROR] [1500052587.267970469]: Failed to load nodelet [/camera/rgb_rectify_mono] of type [image_proc/rectify] even after refreshing the cache: Failed to load library /home/ap4isr/kinetic_workspc/devel/lib//libimage_proc.so. Make sure that you are calling the PLUGINLIB_EXPORT_CLASS macro in the library code, and that names are consistent between this macro and your XML. Error string: Could not load library (Poco exception = libopencv_imgproc3.so.3.1: cannot open shared object file: No such file or directory)

You might want to install opencv. On kinetic, ros-kinetic-opencv should install opencv3.

I tried to excute openni.launch and get these errors:

In general it's hard for us to guess what's going on with only a fraction of the info. For example in your post we don't know what does openni.launch do (it could be the one from openni_launch pkg but it could be what you or someone customized). It's a good practice to share ALL output of roslaunch, including the command and its args itself, so that we can at least get to know what Nodes, Parameters, Topics, Services are started.

For example in your post we don't know what does openni.launch do (it could be the one from openni_launch pkg but it could be something else, like what you or someone customized). Besides if it's from openni_launch, which is just a pkg that contains launch files for sensor driver, it's a bit strange to me that we're seeing error messages that seem related to higher level packages such as image_proc and opencv.
