Background
Forest canopy density is generally the ratio of the area of the vertical projection of the crown in the forest land to the area of the forest land. Forest canopy density is often expressed in terms of a tenth. Forest canopy density is typically measured using a vegetation cover photogrammetry instrument. In order to take a vertical photograph of the vegetation on the ground and obtain vegetation coverage information, it is necessary to raise the camera to a certain height from the ground and have good stability. This operation must be carried out by means of a certain installation and equipment, which is also light, portable and easy to operate. However, the existing measurement supporting device of the vegetation cover image pickup measuring instrument is designed to be more traditional, only in a triangular bracket structure, the rise of the vegetation cover image pickup measuring instrument is limited when the measurement supporting device is operated, and the vegetation cover image pickup measuring instrument is fixed only by a balance weight, so that the fixation is not stable enough, and the measurement is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the main technical problem who solves provides a portable forest closes degree measuring device that stagnates, can conveniently change vegetation cover the height of measurement of measuring apparatu of making a video recording high-efficiently, can cover the stable of measuring apparatu of making a video recording with the vegetation moreover and fix, and convenient to use is reliable.
In order to achieve the above object, the present invention provides the following technical solutions:
this portable forest canopy density measuring device includes the base of disc, and base bottom center department is equipped with perpendicularly and inserts the ground pole for a short time, and base top center department is equipped with the telescopic link perpendicularly, and there is straight rod-like bracing piece at the telescopic link top through hinged joint, and bracing piece one end is equipped with a section of bellows, and the vegetation cover measuring apparatu of making a video recording is installed to the bellows tip, and there is long ground pole of inserting through hinged joint the bracing piece other end.
As a further optimization of the technical scheme, the telescopic rod, the base and the short ground inserting rod are all made of aluminum alloy, and the base is connected with the telescopic rod and the short ground inserting rod through welding.
As a further optimization of the technical scheme, the supporting rod and the hinge are both made of aluminum alloy, and the supporting rod and the telescopic rod are both connected with the hinge through screws.
As the further optimization of the technical scheme, the corrugated pipe is made of aluminum alloy, is connected with the supporting rod through welding, and is connected with the vegetation cover camera shooting measuring instrument shell through screws.
As a further optimization of the technical scheme, the long ground inserting rod is made of aluminum alloy and is connected with the hinge through a screw.
The beneficial effect of adopting above technical scheme is: this portable forest canopy density measuring device can insert the underground with the short earth pole of inserting when using, lets the base paste ground fixed, then adjusts the length of telescopic link. Bend into suitable shape with the bellows, let the bracing piece rotatory around the hinge again, rise to the suitable height in forest upper portion with the vegetation cover camera measurement appearance at bracing piece top, insert the underground with the ground pole of transplanting a long time simultaneously to fixed good bracing piece, the fixed stability of vegetation cover camera measurement appearance is good, thereby measures to the forest degree of closure more accurately. This portable forest canopy density measuring device can conveniently change vegetation cover the measuring height of measuring apparatu of making a video recording high-efficiently, can get up vegetation cover the stable of measuring apparatu of making a video recording moreover, and convenient to use is reliable.

fig. 2 is a plan view of the portable forest canopy density measuring apparatus.
Wherein, 1-vegetation cover camera measuring instrument, 2-support bar, 3-telescopic bar, 4-base, 5-corrugated pipe, 6-long ground inserting bar, 7-short ground inserting bar and 8-hinge.
Detailed Description
The preferred embodiment of the portable forest canopy density measuring device is described below with reference to the accompanying drawings.
Fig. 1 and 2 show a specific embodiment of the portable forest canopy density measuring device:
with reference to fig. 1 and 2, the portable forest canopy density measuring device comprises a disc-shaped base 4, a short ground inserting rod 7 is perpendicularly arranged at the center of the bottom of the base 4, a telescopic rod 3 is perpendicularly arranged at the center of the top of the base 4, the top of the telescopic rod 3 is connected with a straight rod-shaped support rod 2 through a hinge 8, one end of the support rod 2 is provided with a section of corrugated pipe 5, a vegetation cover camera shooting measuring instrument 1 is installed at the end part of the corrugated pipe 5, and the other end of the support rod 2 is connected with a long ground inserting rod 6.
The vegetation coverage camera measuring instrument 1 vertically photographs the surface vegetation to obtain vegetation coverage information. The vegetation coverage photogrammetric instrument 1 performs image preprocessing including image browsing, image magnification and reduction, image rotation, image windowing and cropping, image format conversion, and the like, in preparation for calculating vegetation coverage from an image. The vegetation coverage camera measuring instrument 1 calculates the vegetation coverage of the image and corrects the center projection of the image, calculates the vegetation coverage by adopting an automatic interpretation model aiming at the preprocessed vegetation image, and completes the error correction of the center projection on the result to obtain the final vegetation coverage of the image.
The telescopic rod 3, the base 4 and the short ground inserting rod 7 are made of aluminum alloy, and are firm, durable and good in corrosion resistance, and the base 4 is connected with the telescopic rod 3 and the short ground inserting rod 7 through welding.
