Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings. A plant population canopy porosity measuring device, such as figure 1 , 2 As shown, the adjustment mechanism includes an X-direction linear guide rail module (1) and a Y-direction linear guide rail module (2). There are two described X-direction linear guide rail modules (1), which are respectively fixed on the upper surfaces of the two beams in the X direction of the frame (4) by bolts; the Y-direction linear guide rail modules (2) It is fixed on the upper surface of the slider of the X-direction linear guide rail module (1) by bolts, and is kept perpendicular to the X-direction linear guide rail module (1).

[0028] The laser distance measuring mechanism includes a fixed panel (12) and a laser distance measuring instrument (11). Described fixed panel (12) is a U-shaped structure, is fixed by the side of bolt and Y-direction linear guide module slider (3); Described ...

Abstract

The invention relates to a plant population canopy porosity measuring device and method. The plant population canopy porosity measuring device comprises a frame, an adjusting mechanism, a laser ranging mechanism, a walking mechanism and a control system, wherein the frame is used for supporting and fixing other devices; the adjusting mechanism is used for driving the laser ranging mechanism to move on an XY horizontal plane; the laser ranging mechanism is used for measuring the distance between a plant leaf and a ranging mechanism; the walking mechanism is used for driving the frame to walk; the control system is used for controlling walking, adjustment and ranging of the plant population canopy porosity measuring device. Through a canopy porosity automatic measuring way, online measurement of the plant population canopy porosity is realized; a control system capable of automatically calculating and measuring porosity is adopted, so that online evaluation of the plant population canopy porosity is realized.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and relates to a measuring device and a measuring method for the porosity of a plant group canopy, which realize automatic measurement and evaluation of the porosity between plant leaves. technical background [0002] Vegetation canopy porosity can be expressed by the probability of light passing through the vegetation canopy without being blocked by leaves and stems, and is an important parameter to describe the spatial distribution of canopy structure and leaf density. There are two definitions of plant canopy porosity, namely area porosity and volume porosity. Area porosity refers to the area percentage of pores contained in a unit area, and volume porosity refers to the volume percentage of pores contained in a unit volume, which should vary according to different detection techniques. The porosity usually referred to is volume porosity. According to the principle of statistics, in...
