  Complex plasmas consist of microparticles embedded in a low-temperature
plasma containing ions, electrons and neutral particles. The microparticles
form a dynamical system that can be used to study a multitude of effects on the
level of the constituent particles. The microparticles are usually illuminated
with a sheet of laser light, and the scattered light can be observed with
digital cameras. Some complex plasma microgravity research facilities use two
cameras with an overlapping field of view.
  An overlapping field of view can be used to combine the resulting images into
one and trace the particles in the larger field of view. In previous work this
was discussed for the images recorded by the PK-4 Laboratory on board the
International Space Station. In that work the width of the laser sheet was,
however, not taken into account. In this paper, we will discuss how to improve
the transformation of the features into a joint coordinate system, and possibly
extract information on the 3D position of particles in the overlap region.
