场景仿真

一个场景仿真模型This sample illustrates the use of IR Scene Generator (vpIRSceneGen).  It defines the class myApp, which is derived from vpApp, and overrides the vpApp::onKeyInput() method to allow for additional keyboard input.  The town.acf loads town.flt and allows the user to fly around the database using a UFO motion model.  The tank.acf loads m1_tank.flt and allows the user to fly around the model using the spin motion model.  Both simulate a basic 3-5 micron FLIR setup.  The tank_2chan_flir_nvg.acf shows a comparison of FLIR and NVG sensors.  Notice that changing the part temperatures for the tank has a greater effect on the FLIR image than on NVG until the tank is literally “glowing” hot.  This highlights the difference in the reflectance and emittance portions of the radiometric solution and demonstrates the wavebands in which the sensors are sensitive.
