Problems solved by technology

This method saves manpower over the previous one, but it is still difficult to keep the camera steady
The brackets of these two designs ensure the level of the phase plane, but the method of keeping the camera stable is more complicated, requires more manpower and material resources, has great human influence, and many random factors, which is very inconvenient for field operation
It is not possible to observe the photographed objects at any time, and the accuracy of obtaining vegetation coverage is not high

Embodiment Construction

[0042] See image 3 , the present invention is a portable remote control vegetation coverage integrated measuring instrument, which is composed of a support rod 1, a main rod 2, a push rod 3, a cross rod 4 and a camera 5. The positional connection relationship between them is: the support rod 1 and the main rod 2 are connected by a pin or thread, the main rod 2 and the ejector rod 3 are connected by a pin or thread, and the cross bar 4 is arranged on the fixed circle of the ejector rod 3 In the pipe 6, the camera 5 is fixed on the front end of the cross bar 4.

[0043] The support rod 1, see Figure 4 , its upper part is a section of straight pipe, the lower part is two spiked fork-shaped parts, and the upper and lower parts are connected as one. The material is aluminum alloy tube. The two spikes on the lower part can be inserted into the soil, so that the instrument can maintain better stability when measuring in the field.

[0044] The main rod 2 is composed of 3 telesc...

Abstract

The invention provides an integrated portable remote-control vegetation coverage measuring instrument which is composed of a support rod, a main rod, a post rod, a cross rod and a camera, wherein the support rod is connected with the main rod through pin shafts or threads, the main rod is connected with the post rod through pin shafts or threads, the cross rod is arranged in a fixed circular tubeof the post rod, and the camera is fixed at the end part of the cross shaft. In the invention, by means of improvement of the material, the appearance and the structure of the measuring instrument, stability and controllability of the instrument are improved; by means of development of a digital image processing software system, automation degree for acquiring a vegetation coverage numerical value is improved; and by means of limitation in shooting range, adjustment of a vertical visual angle and automatic focusing of the camera, relatively strict control on the shooting range and edge deformation is achieved and measuring precision of vegetation coverage is improved. The integrated portable remote-control vegetation coverage measuring instrument has practical value and wide application prospect in the field of vegetation coverage measurement.

Description

(1) Technical field: [0001] The invention relates to a measuring instrument, in particular to a portable integrated measuring instrument for vegetation coverage with remote control, which belongs to the technical field of optical computing equipment. (two) background technology: [0002] There are two main traditional methods for small-scale vegetation coverage measurement: visual measurement and photography. The visual measurement method relies on personal experience for field interpretation, which is highly subjective and random; the photographic method uses a camera to obtain vertical imaging of the area to be measured, and then uses computer image processing technology to extract vegetation information and calculate vegetation coverage. At present, close-range photogrammetry has been successfully applied and developed in the calculation of vegetation coverage. A large number of scholars have demonstrated in their research work that photography combined with digital image...
