The space-born and airborne platforms are major means to acquire the earth surface information. However, the airborne
and spaceborne are sometime limited in some special cases such as military area, federal agencies. For this reason, this
paper presents study on a blimp-based low altitude remote sensing platform, which has the characters of stability and
safety and is easy to operate and control. The details of the hardware configuration and work flow are first described, and
some key techniques including calibration, synchronization and aerial triangulation bundle adjustment are emphasized.
In this system, low accuracy digital compass is used due to the limitation of blimp payload and cost. With the simulated
study and real data analysis demonstrates that under the current hardware specification, the accuracy of 3D object
coordinates can reach better than 0.5 m. Moreover, this system can reach equality with the airborne platform with less or
without ground control points (GCPs).
