MEASURING DYNAMIC AND ABSOLUTE DISPLACEMENT

摘要

Disclosed are methods of measuring dynamic displacement of an object. The methods include capturing a plurality of images of a dynamically moving object. The object may include one or two color-patterned target(s) that include two rows and two columns of two contrasting colors (e.g., colors with a difference in hue values of approximately 180). The methods include identifying a reference point of the object (e.g., a center of a color-patterned target or a midpoint between the centers of two color-patterned targets) and measuring the dynamic movement (displacement) of the reference point over time. The images may be captured by a smartphone camera and the smartphone may identify and measure the dynamic movement of the reference point. In view of the constraints of smartphone hardware capabilities, the images may be cropped and/or not displayed to enable the smartphone to process the images and measure the dynamic displacement in real time.
