The invention discloses a panoramic laser scanning device for measuring a forest stock volume parameter. The panoramic laser scanning device comprises hardware including a panoramic laser scanning device shell (5) and a support (1) below the shell, wherein the shell is internally provided with a battery power supply component (12), a laser tree-measuring sensor (11) with a lens, a stepper motor (13) and an integrated PCB (Printed Circuit Board) (14); function selection keys (9), signal indicator lamps (7) and a switch (8) are arranged on the top of the shell; a lens is arranged at the front end of the shell, a display screen (10) is arranged at the rear end of the shell, and a USB (Universal Serial Bus) interface and an SD (Secure Digital) card interface are formed in one side surface of the shell; a level calibrator (2) is arranged on the top of the support; a tree measuring circuit comprises a single-chip computer circuit (A), a signal receiving circuit (B), a function key circuit (C), a signal lamp display circuit (D), an SD card interface circuit (E), a USB interface circuit (F) and a voltage stabilizing circuit (G). The device for measuring the forest stock volume parameter in a non-contact mode is high in efficiency and low in labor intensity, and can provide remote sensing information in the vertical direction.
Description
【Technical field】 [0001] The invention belongs to a scanning instrument for measuring forest sectional area, density and accumulation parameters, which combines laser sensor and computer technology. 【Background technique】 [0002] For the determination of forest accumulation parameters, although the well-known public angle gauge measurement method is labor-intensive and inefficient, the angle gauge principle still maintains its technical advantages. Angle gauges have undergone many improvements over the past half century, but the basic principles remain the same. [0003] For the estimation of regional forest volume and biomass, ground sampling or remote sensing methods are generally used. Remote sensing methods also require ground survey data for modeling. There are mainly two types of ground survey methods: plot survey and corner gauge survey. The former needs to measure each tree, which requires a lot of work and takes a long time. The latter uses angle gauges to meas...
