A height-measuring method comprises following steps:capturing an external marker pattern for generating an input imageexecuting a first recognizing process on the input image for obtaining a marker image corresponding to the marker patternexecuting a measuring process on the marker image for obtaining an image-measuring valuecomputing a height-measuring value based on the image-measuring value.Even if a measured person cannot stably stand,this method can still measure his/her height effectively via computing the height-measuring value by using the marker image.一種身高量測方法,先拍攝外部的標記圖案以產生一輸入影像;接著對輸入影像進行第一辨識處理以取得對應標記圖案的標記影像;再來對標記影像進行量測處理以取得影像量測值;最後依據影像量測值計算身高量測值。本發明透過以標記影像來計算身高量測值,即便受測者無法穩定站立,亦可有效進行身高量測。S400-S406‧‧‧步驟
