Observation device for growth height of plants in sample area and observation method

Abstract

The invention discloses an observation device for growth height of plants in a sample area and an observation method. The observation device comprises an instrument support, a stepper motor, a laser ranging mechanism, an anti-interference assembly and a gradienter, wherein the instrument support comprises a square top frame and four support legs arranged at the lower end of the square top frame, aleft Y-axis guide rail and a right Y-axis guide rail are arranged on the lower surface of the square top frame and connected with an X-axis support through two sliders, and an X-axis guide rail is arranged on the X-axis support; the laser ranging mechanism comprises an infrared laser range finder and a connecting frame, a rack is arranged at the lower end of the X-axis support, a gear mutually meshed with the rack is arranged on the connecting frame, and the connecting frame is glidingly connected onto the X-axis guide rail through the gear and the rack. The observation device has the advantages of being simple, easy and concise to operate, realizing accurate monitoring result and small errors, facilitating compared tracking and the like, and can perform directional observation on different kinds of vegetation in the selected area.

Description

technical field [0001] The invention belongs to the technical field of vegetation growth monitoring devices, and in particular relates to an observation device and an observation method for plant growth height in a sample area. Background technique [0002] The methods for monitoring wild vegetation in the prior art mainly use satellite remote sensing and aerial photography to obtain vegetation images, thereby judging the health and growth of vegetation, or obtain vegetation images by taking pictures on the ground for analysis. However, the current problem is that, due to the wide area of ​​images obtained by satellite remote sensing and aerial photography, it is only suitable for judging the growth of vegetation in large areas, and the resolution of images obtained by satellite remote sensing and aerial photography is low, so it is impossible to accurately obtain vegetation at specific locations health and growth. At present, in the prior art, the growth of different types...

Problems solved by technology

However, the current problem is that, due to the wide area of ​​images obtained by satellite remote sensing and aerial photography, it is only suitable for judging the growth of vegetation in large areas, and the resolution of images obtained by satellite remote sensing and aerial photography is low, so it is impossible to accurately obtain vegetation at specific locations health and growth

At present, in the prior art, the growth of different types of plants in the sample area at different stages can only be measured manually. The method of manual measurement has the disadvantages of time-consuming, low efficiency, etc., and is easily disturbed by external conditions. The manual measurement method used in the prior art is also prone to errors

Therefore, the vegetation growth monitoring methods in the prior art all fail to meet the needs to varying degrees.
