【 摘 要 】
In volcanic surveillance, cameras are largely used allowing amazing images of volcanic eruptions as well as beautiful views of these grand Earth constructions. The Colombian Geological Service through the Volcanological and Seismological Observatory of Popayán (OVSPo) have 10 surveillance cameras looking at three volcanoes present in Provinces of Cauca, Huila and Tolima. However, these cameras were not calibrated previously, which has limited the analysis and exploitation of the information up to now. The development of this work take into account that the calibration process should not change camera parameters like orientation and position and what's more, we consider the access difficulties to reach and stay at the camera stations (volcanic environment). A calibration methodology was developed and applied on three (3) cameras on field, achieving to improve the analysis and exploitation of information within images of volcanic surveillance cameras.【 预 览 】
