Abstract : Hybrid measuring device using EO/IR camera was developed in this paper. 2IN1 module type design to acquire EO and IR image simultaneously was used and also was deigned to acquire EO/IR image, distance and location information at a time by integrating Lidar and GPS module. For outdoor photographing, passive thermal image technique without using additional artificial heating system was adopted, and for convenient use of measurement data, a module to connect UAV and measuring device, measuring device and PC, respectively, was used. External power supply was used for image acquisition module with 12V input, maximum 7A, complete size 500 x 500mm and 6kg in weight. Further test of the device will be conducted to connect with the software designed to detect concrete structure surface defect and damage, thereby applying to field instrumentation.
