Description

Detailed Description of the Invention

  This is mainly related to the method of copying the terrain condition, that is, the undulation of each designated point on the fairway of the golf course, and it relates to the acquisition of digital specification data and the construction of a database.

  In recent years, optical rangefinders have emerged as surveying instruments, and the use of actual measurement devices, which are applications that take advantage of non-contact with the subject, and the development of detailed digital data for topographic maps have also progressed. Therefore, the digital data in the tilted state is obtained by two systems by the method based on the calculation method applying this.

“Patent Publication 2002-346019”
A virtual golf course is created by collecting data.
Although there is a description that the location information is included, the source, such as the acquisition method and storage location, is unknown, and the measurement process is not covered.

“Patent Publication 2009-151323”
This is a feature technology that has a process of dividing the grid on the ground surface and uses a three-dimensional solid figure to perform data interpolation processing.
Although there is an arrow indicating the inclination direction and the magnitude of the inclination of the terrain, the process of the fact that the inclination direction on the map screen is specified as “azimuth” is not disclosed.
Moreover, when the magnitude of the inclination angle is represented by the length of the arrow, there is a practical contradiction that a longer arrow is drawn at a place where the contour lines are crowded. This solution is also not shown.
This is a technique for improving the accuracy of data on the four sides of the three-dimensional solid figure, not the data indicating the state of the ground plane.

Problems to be solved by the invention

In the case mentioned above, the identification of the designated area or the designated point is easily passed as if it can be made only by the XY coordinate lot number, but actually the lot number alone does not function as an identification factor. The reason is that if the attributes are the same, it does not make sense for identification. For example, the entire area is completely flat and the direction of the hit ball does not change. This makes no sense to move, so it is necessary to obtain the identification function by acquiring attribute data to be added to the coordinate lot number.
Further, the plane twist is an indeterminate factor of attribute data, and if it remains as it is, it will hinder the identification of the designated area or designated point. Therefore, eliminating the planar twist needs to be included in the solution.
In addition, whether it is actual or virtual, there is a need for a data grasp regarding the state of the ground surface that is directly involved in golf play, especially the slope state. The data function must be reproducible whether it is virtual or real. In other words, since it is proved whether or not the function is performed when the reproduction is performed using the apparatus, it is a problem to drive and reproduce the transfer apparatus. However, if the data is left in a set of four locations, planar twisting occurs. From this point of view, this must be overcome.
In addition, since the point is specified as the preliminary work, it is necessary to reassemble the data at the four points as they are and assign them to some representative.

Means to solve the problem

First, an overhead view of the golf course is covered with a grid, and coordinates are set at each intersection. In addition to this, the feature of the similar triangle is applied to solve the problem. The data points are 3 points and are handled as a set. Therefore, a strict standard is also set. It means that the positional relationship between the grid and the internal triangle is fixed. The case of actual measurement and the case of calculation are exactly the same.
It is a feature of the present invention that the four-point data is converted into a set of three-point data by normalizing the positional relationship. Therefore, a concrete measure was taken, using an actual measurement device, cutting out a square three-dimensional block, and arranging triangular points on the ground surface according to the standard.

  Then, it will be described specifically. FIG. 1 is an overhead view of a course. Applying the grids of east, west, south, and north, each intersection is named P (Xn, Ym). Data actually measured for each intersection is collected and stored as an attribute for each point, and becomes a database. A, b, and c shown by the enlarged view 12 are target points, and this elevation difference is actually measured by the measuring device. 2 and 3 show the measuring apparatus.

  Subsequently, the standard will be described with reference to the enlarged view 12. a. b. c is each vertex of the equilateral triangle. A. b. c is actually measured, and the altitude difference, that is, the value of a minus b and a minus c is stored to form a database. Since this indicates the tilted state as it is, it is possible to reliably transfer using the principle of a similar triangle by maintaining this positional relationship. FIG. 4 is a diagram showing the principle of realization of the inclination on the practice board, and shows that the line connecting the targets becomes the reference. In the actual measurement, the measurement measured based on true north is corrected to match the target.

  In the case of using topographic map data, a model is created as four three-dimensional blocks adjacent from the grid on the above-described overhead view, and a triangular point is drawn on the ground surface according to the standard. Elevation values for the triangular points a, b, and c are calculated using data at the four corners of the block. The result is handled as set data in the same manner as described above.

  In the past, there was almost no way to measure the height except that it was done with a stick on the ground. That is, the process of touching the ground is unavoidable, and the horizontal distance of the measurement point is determined by the grounding point. Therefore, a large amount of work time is required only by marking the point.

  This means that as the number of measurement points increases, the work process is increased as it is. Therefore, it is necessary to prepare for an enormous burden to subdivide and measure the entire golf course.

In the present invention, as a solution to the above problems, a set of three points is measured simultaneously, and the objective is to instantaneously cover the post-processing area such as transmission and storage of acquired data. The goal is to repeat.

The combination of three optical distance measuring devices, which are digital measuring devices, as shown in FIG. 2 and FIG.

This will be described with reference to FIG. Two columns of equilateral triangles are perpendicular to the column 2 penetrating the center of gravity of the column 2 suspended from the center of the three-legged float 6 floating in the donut-shaped water tank 4 in the middle and near the lower end. Thus, three straight pipes 5 having the same diameter and length installed in parallel with the support are supported at the apexes of an equilateral triangle assumed on the plate surface. The optical rangefinder 1 is fixed to the upper end of each straight tube so that the light passes through the straight tube, and the switch input / measurement value output is communicated to an external personal computer or the like wirelessly or by wire.

The invention's effect

  In the old technology, this type of measurement always involved the process of touching the ground. In the type that comes into contact with the ground, the maintenance of verticality is broken every time it moves, greatly affecting the work efficiency. Moreover, if one set of measured values at three locations is obtained for each location, the work process is tripled. Also, if the work itself is done by hand, trivial mistakes may be lost. Recovering this mistake alone is not easy. As a result, although the entire work is simple, it can be seen that it is difficult to obtain stable results.

  However, if the non-contact characteristic of the optical distance measuring device is utilized, if you cruise in the air at a constant speed, you can perform continuous measurement at equal intervals by simply determining the timing of the automatic switch. There is no need to mark measurement points, and that alone is a dramatic improvement in efficiency. Since it is a digital standard, it can be programmed in advance from simultaneous measurement to data transmission, which is also effective in this respect.

    On the other hand, reading of the measurement value is not necessary for human visual recognition, and is completed by light emission and reception of the device itself, so that there is no trouble in night work. It can be said that it can handle work after the golf course is closed at night. It is the same thing, but it may be an advantage that only one worker can operate the equipment, and it can work without trouble even in rainy weather.

  In this way, the innovation of equipment will make it possible to create data on the plane of a golf course, which has been considered difficult, so there will be some industrial fields that will spread. By the way, it is possible to design a simulation space in the indoor practice field from the copied database, and it will also bring progress as a basic data to the ground structure in the virtual space as in the previous example.

These are an overhead view and a partially enlarged view. Is a perspective view of the block. Is a plan view. Shows the principle as an image. Is a plan view. FIG.
