Hava Lazer Tarama Sistemi, Uygulama Alanları ve Kullanılan Yazılımlara Genel Bir Bakış

Hava LiDAR sistemleri bir hava aracının altına monte edilen tarayıcıdan gönderilen lazer ışının gidişdönüş süresini kaydederek yer objeleri ve algılayıcı arasındaki mesafeyi hesaplayan aktif bir ölçme sistemidir. Sistem dâhilinde bulunan GPS ve INS sistemlerinden alınan konum ve dönüklük verisi ile beraber taranan objeye ait konum hesaplanır. Bu şekilde yeryüzüne binlerce lazer ışını gönderebilen sistem, fiziksel yeryüzüne ait yüksek yoğunluklu ve referanslandırılmış üç boyutlu (3B) veri doğrudan elde edilmektedir. Klasik ölçmeler ile yaklaşık aynı doğrulukta, hava fotogrametrisinden daha hızlı oluşturmaya imkân vermektedir. Bu çalışmada hava LiDAR sistemlerine genel bir bakış ile beraber günümüzdeki uygulama alanları, kullanılan lisanslı ve lisanssız yazılımlar ve veri sağlayıcılar ile ilgili bilgi verilmektedir.

An Overview to Airborne LiDAR System, Application Fields and Popular Pointcloud Softwares

Airborne LiDAR system is mounted on an aircraft under the round-trip time recording the laser beam sent from the browser place objects and an active measurement system that calculates the distance between the sensors. Along with the location data from GPS and INS systems and introversion included in the system to calculate the position of the object being scanned. In this way the earth that can send thousands of laser beam system, three-dimensional physical earth of high density and were referenced (3D) data is obtained directly. Roughly the same accuracy with conventional surveying, photogrammetry, are allowing the air to create faster. In this study, an overview of the lidar system together with air current applications are given information about licensed and unlicensed software and data provider used.
