Description

【００１０】
【課題を解決するための手段】
上記の目的を達成するため、本発明のビデオ式非接触伸び計は、複数の標線マークが付された試験片をカメラで刻々と撮像して得られる画像データを用いて、試験片の標線マーク間の伸びを計測するビデオ式非接触伸び計において、設定されたタイミングで、試験片の画像データを、その時点における伸びおよび荷重データと関連づけて記憶する手段を備えていることによって特徴づけられる。 [0010]
[Means for solving the problem]
In order to achieve the above object, the video type non-contact extensometer of the present invention is a video type non-contact extensometer that measures the elongation between the benchmark marks of a test piece using image data obtained by continuously capturing images of a test piece having a plurality of benchmark marks with a camera, and is characterized by having means for storing the image data of the test piece at a set timing in association with the elongation and load data at that time.

Claims (1)

複数の標線マークが付された試験片をカメラで撮像して得られる画像データから、各標線マークの刻々の移動量を求めて、その標線マーク間の試験片の伸びを計測するビデオ式非接触伸び計において、設定されたタイミングで、試験片の画像データを、その時点における伸びおよび荷重データと関連づけて記憶する手段を備えていることを特徴とするビデオ式非接触伸び計。A video-type non-contact extensometer measures the elongation of the test piece between the benchmark marks by obtaining image data by capturing an image of the test piece with a plurality of benchmark marks using a camera and determining the moment-to-moment movement of each benchmark mark. The video-type non-contact extensometer is characterized by comprising a means for storing, at a set timing, the image data of the test piece in association with the elongation and load data at that time.
