    The development history of lidar

    The development history of lidar.Since the first photo was taken by Daguerre and Niepce in 1839, the technique of using the photo to make a photo plan (X, Y) has been in use today. In 1901, the Dutch Fourcade invented the stereoscopic observation technology of photogrammetry, which made it possible to obtain ground three-dimensional data (X, Y, Z) from two-dimensional photographs.

    The use of lidar in surveying and mapping

    The laser scanning method is the main way to obtain 3D geographic information, and the data results obtained through this method are also widely used in resource exploration, urban planning, agricultural development, water conservancy engineering, land use, environmental monitoring, transportation and communication, earthquake prevention and disaster reduction.

    Classification of Lidar

    According to the working mode, Lidar can be divided into pulse lidar and continuous wave lidar. According to the different detection technology, it can be divided into: direct detection lidar and coherent detection lidar.

    Advantages of Lidar

    Compared with ordinary microwave radar, because it uses laser beam, the working frequency of lidar is much higher than that of microwave, so it brings many advantages

    What is the principle of lidar ranging?

    ​The basic principle of lidar ranging is to calculate the distance of the target by measuring the round-trip time of the laser emission signal and the laser echo signal.
