Description

The apparatus for tree ring measuring apparatus

The present invention relates to an apparatus for measuring and analyzing the annual rings and growth states of trees, and more particularly, to an apparatus for measuring the numbers and shapes of rings from a single plate and a core of a tree to be measured by a CCD camera, Is analyzed with a computer and dedicated software to investigate the age of the tree, the diameter of the tree, the height of the tree, the area of the tree, and the growth of the tree.

The most important and fundamental thing in the study of forestry is to investigate how the growth of the trees and the growth of the trees during the growing season changes every year. In other words, the comparison of the difference of the growth condition of the trees and the records of the environmental condition at that time, which is caused by the difference of the distance between the trees, can find the most appropriate growth environment for the various trees. Therefore, It becomes the most fundamental research activity in the afforestation business.

However, conventionally, the method of examining the tree of the tree has been performed by pure handwork. That is, as shown in Fig. 1, the end plate 1 cut perpendicularly to the longitudinal direction of the tree and having a height of about 3 to 5 cm or a diameter of 4 to 5 mm The core 2 of the core 2 was extracted and the distance between the rings 1A and 2A shown on the outer surface thereof was directly measured. When the distance between the rings was narrow, a magnifying glass was used together. Then, the peeling of the end plate 1 with a very thin height was made to make it more precisely with a microscope.

The above-described manual measurement method can not only cause measurement errors depending on the measurer, but also can be applied to a sample according to the height of a tree and a sample having the same height as at least four And the measurement of the measured values is carried out separately after completion of all the measurements. Therefore, there is a problem that it takes a long time from the measurement to the analysis.

In order to reduce the measurement error in the measurement, there is an apparatus for reducing the measurement error by fixing the core to a sample mounting table capable of sliding, moving the sample mounting table while observing the core with a magnifying glass, and measuring the movement amount with a digital caliper , And the measurement error is reduced.

The present invention solves all the problems of the conventional method and apparatuses for measuring a tree limb, and it is an object of the present invention to provide a method and apparatus for measuring the spacing between rings using a computer and automatically analyzing the measured values, The present invention provides an apparatus and method for easily measuring and analyzing a state of an object.

The features of each component of the inventive wood ring wheel measuring apparatus constructed as above will be described in detail as follows.

The drawer in the lower frame 314A constituting the main frame is for temporary storage of various tools and measurement data required for measurement and is used for the temporary storage of the Cassidy camera moving base The through hole H formed in the corner of the upper plate by the length of the moving groove A is for a connecting cable between the CCD camera 312 and the camera / computer interface unit 315, and is formed in the lower frame 314A The balance frame 314C fixed at both ends between the CCD camera moving base 313 and the sample fixing base 311 is used to prevent the main body 310 of the present invention device from falling down in the backward direction when the large and heavy veneer is fixed will be.

The upper, lower, left, right, and backward movement adjusting knobs 312A1, 312A2, and 312A3 provided in the position adjusting body 312A constituting the CCD camera 312 fix the wood end plate or core, which is a measurement sample, And the illuminator 312C is for adjusting the brightness of the object to be photographed.

An on / off switch 313B of the illuminator and an adjustment handle 313C for fine movement of the CCD camera are provided on one side of the CCD camera moving base 313 on which the CCD camera is assembled The illuminator 312C can be turned on and off on the CCD camera moving base 313 and the CCD camera 312 can be finely moved in the left and right direction.

A fixing groove G is formed in the longitudinal direction at the center in the rear width direction of the sample holder 311 and two sample holders 311A and 311B are assembled in the groove. Since the sample fixture 311A and the core fixture 311B can be moved along the fixing groove and the distance between the two sample fixtures 311A can be freely adjusted, the diameter of the sample fixture 311 Can be measured.

The core fixture 311B is composed of a base plate 311B1, a tightening plate 311B2, a fixing plate 311B3, a fastening 311B4 and a fixing member 311B5, The rectangular plate 311B3 is fixed to the corner of the square base plate 311B1 provided with the fastening member 311B4 and is fixed to the base plate 311B1 so that a constant gap B in the longitudinal direction is formed. The rectangular fastening plate 311B2 is assembled on the fastening plate fixing surface and the core fastening plate is assembled to the rear fixing groove G of the sample fixing plate 311 by the fixing member 311B5, The clamping plate 311B2 is moved up and down on the base plate 311B1 by the fastening member 311B4 so that the longitudinal gap B between the clamping plate 311B2 and the clamping plate 311B2, Is changed. That is, if the fastening plate is moved downward by using the fastener 311B4 after inserting the measurement target core C between the gaps B in a state where the fastening plate is moved upward to enlarge the gap B with the fastening plate, The core is fixed to the gap B as the gap B narrows.

There are two methods for measuring the cutting-edge ring using the apparatus of the present invention, which are constructed as described above, using a single plate and a core.

First, a method of using a single plate is as follows: a step of making a single plate 1 as shown in Fig. 1 (a) by cutting a tree to be measured perpendicularly to the longitudinal direction according to necessary positions; A step of drawing a measurement reference line L that vertically crosses the tree center 52 on the ring face of the single plate 51 and the step of grasping one reference line L of the measurement reference line L on the right and left movement paths of the CCD camera 312 Fixing the end plate on which the measurement reference line L is formed to be parallel to the sample holder 311 using the sample fixture 311A, turning on the power of the main body and the computer and activating the measurement program, A step of aligning the focal point of the CCD camera with the center of the veneer while viewing the displayed veneer image and a step of moving the CCD camera from the center of the veneer to one side so as to be displayed on the computer monitor image by the CCD camera When the central vertical cross-target line is matched to the rings a step of clicking through the mouse or computer keyboard.

Second, the method of using the core includes a step of extracting the core 2 from the measurement object tree as shown in FIG. 1 (B), a step of extracting the extracted core from the sample fixture 311 A step of turning on the power of the main body and the computer to start the measurement program; and a step of adjusting the focus of the CCD camera to one side of the core corresponding to the center of the tree while watching the core image displayed on the computer monitor And a step of moving the CCD camera from one side of the core to the other side and clicking the center of the vertical cross target line displayed on the computer monitor image by the CCD camera when the center of the vertical cross target line coincides with the ring.

It is preferable that the above measurement is performed on four cores extracted from four directions in four directions, that is, four corners of the north, south, south, and south, based on the center of the tree per single veneer for accurate data analysis. Particularly, since the veneer is made by completely cutting the tree, the core is extracted and measured in order to measure the living tree. Since the image of the tree displayed on the computer monitor can be reduced and enlarged, accurate measurement can be performed even when the interval between the rings is very narrow.

The intervals and clicks between the rings measured as described above are calculated and analyzed by a dedicated analysis program of a computer to calculate the growth state such as the tree's age, chest diameter, height, chest circumference, The detailed growth status of the trees is analyzed by outputting them as a table and a graph.

As described above, the apparatus for measuring a tree limb of the present invention can measure precisely because the interval between rings is measured while viewing an image of a tree displayed on a computer monitor freely expandable and contractible, and the measured values can be precisely It has the advantage of being able to grasp the growth status of the tree accurately and easily.

In addition, since the measurement and analysis for determining the tree growth state are performed in one place by the present invention apparatus, the measurement and analysis time are saved, thereby reducing the work load.
