Chapter 6: Measurements
Establishing a measurement scale is required to set a
specified number of pixels in the image equal to a scale
unit size, such as millimeters, meter, inches, feet, or pixels.
To define a measurement scale, the analyst needs to
select two points in the image with a known scale, then
specify that scale size. Once created, all measurements
are computed and displayed using the scale unit. If no
measurement scale exists, the default scale will be 1 pixel
= 1 pixel.
To perform timing measurements accurately, a time stamp
(date and time) is embedded into every frame captured.
The PCC software function, for example, calculates the
time difference between two event frames (start / end of
an event) or from the captured image being displayed to
the trigger (t0) frame automatically.
Coordinate measurements are calculated from an Origin
point pixel, by default the top-left corner of the image;
however, the Origin can be changed when performing
measurements. Each coordinate consists of two numbers
(x1, y1) indicating the position of a pixel in the image on
the two-dimensional plane from the Origin point.
Using ‘Distance and Angle and Speed’ instant
measurement tools makes analyzing launch speed,
angle, and angular speed or the revolutions of a rotating
object extremely simplistic.
They allow engineers’ developing large caliber weaponry
to analyze the effect the design of the shell has on the
projectile trajectory based on launch speed and angle
to determine the optimal performance, or manufacturers
of scientific equipment like anemometers to determine
the best size and type motor to enhance their product by
performing angular speed (rotational measurements) on
the motors used to generate an electric current as they
rotate.
