Abstract

PURPOSE:To easily measure the range up to a body by detecting the elevation angles to the upper end and lower end of a body having specific length which is set at distance, and performing arithmetic processing. CONSTITUTION:The range measuring instrument 1 is equipped with an ocular lens 2, lens barrel 3, and objective lens 4 and constituted by fitting an arithmetic part and a display part 7. Then, the measuring instrument 1 measures the elevation angle alpha to the upper end of the body 12 and the elevation beta to the lower end and inputs the measured values to the arithmetic part. Further, the length L of the body 12 is stored in the arithmetic part. Then, the difference theta between the elevation angles alpha and beta is calculated and the length L is divided by the absolute value of the angle theta to calculate the distance from the observation point to the body. Thus, the distance to the body is easily measured and the distance to a pin is easily measured on a golf course.

Description

[Detailed description of the invention] <Technical field of invention> The present invention relates to a distance measuring device.

<Prior art and problems> Conventionally, when measuring the distance to the bottle at a golf course,
Calculations were made by looking at all the landmarks such as bunkers and stakes set up in the hole, or by observing the bottle with the eyes.

However, the location of landmarks on the course is a matter of discretion.
Furthermore, if the position of the bottle on the green is off-center, it is impossible to accurately calculate the distance. On the other hand, the visual observation method relies heavily on experience and experience, and calculations are difficult for golfers with a 1-hump cap.

<Objective of the Invention> An object of the present invention is to provide a distance measuring device capable of measuring the distance f, flrIv to an object.

<Configuration and Effects of the Invention> In order to achieve the above object, the present invention detects the elevation angle of ficl with respect to the upper end of an object, and detects the elevation angle of ficl with respect to the lower end of the object.
means for detecting the elevation angle of the object; means for storing the length of the object; and calculating the absolute value of the difference between the first elevation angle and the second elevation angle detected by the detection means and storing the length of the object in the storage means. The present invention is characterized in that it has means for calculating the distance from the current position to the object by dividing the length by the difference in corner marks.

According to the present invention, the distance to an object can be easily measured, and when applied to golf, the distance to a bottle can be easily measured.

<Embodiment 1 of the Invention> FIG. 1 is a front view of a distance measuring device l according to an embodiment of the present invention, in which an eyepiece portion 2. It is shaped like a telescope and includes a lens barrel 3 and an objective lens section 4, and a reset switch 5 is provided on the outer surface of the lens barrel 3. It is equipped with a measurement switch 6 and a distance display section 7.

FIG. 2 is a block diagram of the electrical system of the distance measuring device ff1l, which includes a memory 8 for storing the length of the object to be measured, 8° angle detection sensor 9. Arithmetic processing unit (CPU) l O, distance mR indicator 7. It consists of a reset and measurement switch (SW) 5°6t.

The angular position sensor 9 is provided with a visual field pressure as seen from the eyepiece portion 2, and is capable of detecting the entire elevation angle when the observation object is aligned with the steam horizon. As the angle detection sensor, an optical sensor such as a low-resolution encoder or a mechanical sensor such as a potentiometer that converts an α-space signal into an α-space signal can be used.

To explain the operation of the above embodiment, first, as shown in FIG.
Calculate from the length L.

The above calculation method will be explained with reference to chart 70 in FIG.

First, in step 21, the reset switch 5 (FIG. 1) is pressed, and the angle of the angle detection sensor 9 is set to OK (step 22).

Next, the player observes the bin 12 through the eyepiece 2 and aligns the horizontal line within the visual field with the top of the bin 12 (step 23). When the measurement switch 6t is turned ON (step 24), the first elevation angle α is stored in the memory 8 (step 25).

Next, the horizontal line in the field of view is made to coincide with the lower end of the bin 12 (step 26), and the measurement angle is set to ft0N (step 27), and the second elevation angle β is stored in the memory 8 (
Step 28).

In step 29, the CPU 10 calculates the absolute value θ of the difference between the elevation angles α and β, and further divides it by the absolute value θ of the bin length If stored in the memory 8 to calculate r (step 30). This r is 1 distance gf, which is the distance from the ball 11 to the bottle 12 in FIG. r is displayed on the display section 7 of FIG. 1 in step 31.
