Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem wherein distance perspective is important in the sense of making up a stable shot in a sport as golf which forces a play in a different situation each time, training in actual courses is needed for improving the distance perspective, various kinds of golf distance measuring devices for training are available in the sense of assisting it, but not widely prevalent as sports auxiliary option devices because of latent psychological burden resulted from a violation of provisions in an official sport. <P>SOLUTION: Paying attention to a cellular phone with camera with high penetration rate such that it can be said that everyone has a cellular phone nowadays, the distance from a photographing position to a pin is measured by a golf training distance measuring application installed to the cellular phone. According to this, by using the cellular phone that is a daily commodity as a platform, the psychological burden of a user can be reduced, and a convenient function for naturally learning the distance perspective in a casual sense can be provided. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、カメラ付き携帯電話上で動作する距離測定方法及び装置に関するものである。 The present invention relates to a distance measuring method and apparatus operating on a camera-equipped mobile phone.

従来ゴルフ用距離測定装置は、高価なものに関してはレ−ザ−などを利用するものもあり、安価なものでは特許文献１、実用新案文献１のような望遠鏡様の光学系装置に透過式のメジャ−を組み合わせ鏡筒視野上でのピンの高さ（長さ）とメジャ−を対比させて測距するものとして提供されている。
特許公開２００２−３５７４１７号公報 Conventional distance measuring devices for golf use a laser or the like for expensive ones, and those that are inexpensive are transmissive to telescope-like optical system devices such as Patent Document 1 and Utility Model Document 1. A combination of measures is provided to measure the distance by comparing the height (length) of the pin in the field of view of the lens barrel with the measure.

Problems to be solved by the invention

本来、ゴルフのように毎回違った状況でのプレ−を強いられるスポ−ツにおいて距離感覚というのは安定したショットを作り上げる意味でも大切なものである。これを養うためには実際のコ−スに出て多くの距離感覚を養う練習をする必要がある。これを助ける意味で練習用としてゴルフ距離測定装置が各種販売されている。しかしながら正式競技では規定違反ということからくる潜在的な心理負担も影響してか、スポ−ツ補助用のオプション装置としては広く普及してはいない。本発明では、距離測定機能を現在では多くの台数が普及しているカメラ付き携帯電話上で実現することにより前述の心理負担を軽減した上で、気軽にゴルフの上達を促す補助環境の提供を目的とするものである。 Originally, the sense of distance is important in the sense of creating a stable shot in sports where players are forced to play in different situations each time, such as golf. In order to cultivate this, it is necessary to practice in the actual course to cultivate a sense of distance. In order to help this, various golf distance measuring devices are sold for practice. However, in the official competition, it is not widely used as an optional device for assisting sports, possibly due to the potential psychological burden resulting from violation of regulations. In the present invention, the distance measurement function is realized on a camera-equipped mobile phone, which is currently widely used, and the above-mentioned psychological burden is reduced, and an auxiliary environment for easily promoting golf is provided. It is the purpose.

The invention's effect

本発明は、合理的に練習を行いたいと考えるゴルフプレ−ヤ−に対し、既に普及しているカメラ付き携帯電話上の距離計測アプリケ−ションとして提供されるもので、簡便な操作によってピンまでの距離を計測し、感覚とのギャップを毎回のチェックによって埋めて行き、絶対音感ならぬ絶対距離感を得ることを助け、真価を発揮するものである。 The present invention is provided as a distance measurement application on a camera-equipped mobile phone that is already popular for golf players who want to practice reasonably. Measure the distance and fill the gap with your senses every time, help you get a sense of absolute distance that is not absolute pitch, and demonstrate its true value.

以下、本発明の実施形態を、図１、図２に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2.

本発明では、焦点距離等機種毎に仕様が異なるカメラ付き携帯電話に対応するために、計測の為のリファレンステ−ブルを作成するキャリブレ−ションを行う。図１では、その様子を説明していている。「ピンまでの距離：Ｚ１」（５）が予めわかっている練習場等で距離：Ｚ１を数値入力し、そこからカメラ付き携帯電話（１）で「ピン」（３）を撮影する。「ピンの高さ：Ｙ１」（４）も同様にわかっているので同じく高さ：Ｙ１も数値入力する。この時に撮影された撮影画像（６）は携帯電話のストレ−ジに保存されるが、これをアプリケ−ション側から呼び出して、その画像上で「ピン接地点」（７）と「旗頂上点」（８）の二点を手動で指定し、画像上でのピクセル数を「ピン長ピクセル数：Ｙ２」（９）として取得する。ここで得られた「Ｙ１］「Ｚ１」「Ｙ２」を距離計測用リファレンステ−ブルとしてし保持され、距離測定ステ−ジでの距離演算に利用される。また、このリファレンステ−ブルは、更新されない限りはアプリケ−ション起動時に自動的にストレ−ジから読み込まれ自動的にセットされるものとする。 In the present invention, a calibration for creating a reference table for measurement is performed in order to support a camera-equipped mobile phone having different specifications for each model such as a focal length. FIG. 1 illustrates this state. The distance: Z1 is input as a numerical value at a practice field where “distance to the pin: Z1” (5) is known in advance, and the “pin” (3) is photographed from the camera-equipped mobile phone (1). Since “Pin height: Y1” (4) is also known in the same manner, the height: Y1 is also entered as a numerical value. The photographed image (6) photographed at this time is stored in the storage of the mobile phone, which is called from the application side, and “pin grounding point” (7) and “the flag top point” are displayed on the image. "(8) is manually specified, and the number of pixels on the image is acquired as" number of pin length pixels: Y2 "(9). “Y1”, “Z1”, and “Y2” obtained here are held as distance measurement reference tables, and are used for distance calculation in the distance measurement stage. Further, this reference table is automatically read from the storage and automatically set when the application is started unless updated.

距離計測ステ−ジでは、図２のように実際に距離計測を行いたいコ−ス上の場所からピンを撮影し「計測時撮影画像」（１０）を得る。次にキャリブレ−ション・ステ−ジと同様にして「ピン長ピクセル数：Ｙ３」（１３）を取得する。この値と、距離計測用リファレンステ−ブルとの演算により最終的に撮影点から「ピンまでの距離：Ｚ３」（１４）を生成し、アプリケ−ション上に表示するものとする。 In the distance measurement stage, as shown in FIG. 2, a pin is photographed from a place on the course where the distance measurement is actually desired to be performed to obtain a “photographed image during measurement” (10). Next, “pin length pixel number: Y3” (13) is obtained in the same manner as in the calibration stage. It is assumed that “distance to pin: Z3” (14) is finally generated from the photographing point by calculation of this value and the distance measurement reference table, and displayed on the application.
