Resumen
LIDAR es el acrónimo en inglés para Llght Detection And Ranging, éste hace referencia a una tecnología que permite medir distancias al terreno desde un sensor (generalmente ubicado en una aeronave). El sistema está basado en la tecnología Láser (acrónimo en inglés de Light Amplification by Stimulated Emission of Radiation), en dos frecuencias (azul-verde e infrarroja), en un patrón de arco a través del rumbo de vuelo de la plataforma aerotransportada; graba las señales de llegada de las reflejadas por la superficie del terreno, la diferencia del tiempo medido entre los dos pulsos de luz reflejados, es convertida en distancia. Para la aplicación de esta técnica es necesaria la combinación de varias tecnologías entre ellas: GPS ( Global Positioning System), sistemas inerciales, láser y cámaras digitales, todo instalado en la plataforma de un helicóptero o avión debidamente configurado, que además requiere del apoyo terrestre con receptores GPS, ubicados sobre estaciones en tierra, a las que se le determinaron las coordenadas previamente con un alto grado de confianza, de manera que sea posible obtener coordenadas y elevación de todos los puntos observados desde el sistema aerotransportado.
LIDAR is the acronym in English for Llght Detection And Ranging, this refers to a technology that allows measuring distances to the ground from a sensor (generally located in an aircraft). The system is based on Laser technology (acronym for Light Amplification by Stimulated Emission of Radiation), at two frequencies (blue-green and infrared), in an arc pattern across the flight path of the airborne platform; records the arrival signals of those reflected by the ground surface, the difference in time measured between the two reflected light pulses is converted into distance. For the application of this technique, the combination of several technologies is necessary, among them: GPS (Global Positioning System), inertial systems, lasers and digital cameras, all installed on the platform of a properly configured helicopter or plane, which also requires ground support. with GPS receivers, located on ground stations, whose coordinates were previously determined with a high degree of confidence, so that it is possible to obtain coordinates and elevation of all points observed from the airborne system.
