6－2. EPS-02Hv2 Features
＊Measurement sensor is detected from the image for recognizing the measurement
location
The measurement object and measurement sensor are captured by a camera, and the
measurement sensor is found within the image for identifying the measurement location. The
recognized measurement location is a relative location within the camera image.
Any user-selected color can be specified for the measurement sensor. However, selecting a
color with the same tone as the background color will result in a reduced rate of recognition
and even mistaken recognition in certain cases.
The measurable range is the area shown in the camera, but it is restricted to a range that can
be recognized by the measurement sensor.
＊Automatic control by software
Measurement sensor recognition from the camera image and control of the magnetic field
measuring instrument are performed automatically. The measurement results can be output
as a CSV file, and the image can be output in BMP format.
Also, because the software is a Microsoft Windows application, it provides an
easily-accessible interface that uses mouse operations while viewing the screen.
＊Visual display of measurement results
The measurement strength distribution and camera image are displayed as a superimposed
image on the computer screen. Also, the mouse pointer in the image can be used to confirm
measurement results for any selected position.
In addition, an interpolation view of the surrounding strength can be used to provide easier
assessment of the generation points.

6－3. Measurement Principle
The EPS-02 system performs two main operations for enabling visualization of the electromagnetic
field. First, it performs image recognition that identifies the measurement sensor location from the
recording image. Second, it provides a color-coded distribution on the image indicating the strength of
the signals detected by the measurement sensor.
In image recognition, 640 x 480 pixel video from the camera is monitored in real time, and a
specific color only is extracted based on the specified parameters for "hue", "brightness", and
"saturation". By finding the focal point of the area with the specific color, the location of the specific
object (measurement sensor) can be found in the image.
If an object with the same color as the specified color, but that is not the measurement sensor,
appears in the image, the measurement sensor location cannot be recognized correctly because the
focal point of all objects of this color is calculated. Therefore, the parameter settings for "hue",
"brightness", and "saturation" that are used to detect the measurement sensor, the brightness and
light exposure in the recording location, and selection of the lighting are important factors. Depending
on the color of the measurement object, in certain cases, measurement sensor covers that are
provided as standard for magnetic field measuring instruments cannot be used.
The magnetic field strength is measured using a configuration with the FT-3470-91 magnetic field
measuring instrument by Hioki, which is compliant with the IEC-62233:2005 (JIS TS C0044:2010)
standards for protecting from human exposure due to household appliances. The magnetic field
sensor consists of 100 cm2loop coils combined as the X, Y, and Z rectangular coordinates for
capturing the magnetic flux of the respective field. (This magnetic field sensor is a specially-order
model for this system, and other models may not work correctly in this system.)
Magnetic Field Measurement Process
The FT3470-91 is connected to the PC by a USB cable. This connection is used by the FT-3470-91
to output 10 Hz to 400 kHz magnetic field strength data at four times per second. This strength is
superimposed on the PC image for creating a magnetic field strength distribution diagram. If data
arrives at the same image location, it is overwritten or written by Max Hold.
The magnetic field data can be displayed by selecting the units of magnetic flux density T (tesla) or
G (gauss), or magnetic field strength A/m (ampere per meter) in magnetic field strength mode. In
human exposure mode, the limit value can be displayed as a percentage (%) based on the reference
level for general public exposure and reference level for occupational exposure specified in the
ICNIRP Guidelines* for 2010.
In this case, the total amount of the magnetic field for the X, Y, and Z axes for 10 Hz to 400 kHz is
combined and displayed, and no information about the frequency is provided.

Image Recognition Setting
Adjust the three parameters, Hue, Saturation, and Value, in the Image Processing Setting so
that the color of the magnetic sensor can be recognized. The binarized image on the right side can
be changed by moving the slider of each parameter.
Hue: Sets the hue, such as red, blue, or yellow
Saturation: Sets the intensity and purity of a hue
Value: Sets the lightness of a color.
Adjust the parameters until the magnetic field measurement sensor is recognized as a circle and
no other object is recognized. If there is any object whose color is similar to that of the sensor in the
background, hide the object or change the color of the sensor.
Once the sensor is recognized as a circle, click OK to complete adjustment.
Procedure for successful sensor recognition setting
1. Set the Saturation and Value to 0.
2. Adjust the Hue so that the sensor is most clearly recognized.
3. Increase the Saturation gradually to remove other recognized areas around the sensor.
Do not increase the Saturation excessively to prevent the recognized sensor area from
being impaired.
4. Increase the Value in the same manner.
5. Finally, move the sensor outside of the camera view, and make sure that there is no
object to be recognized.
If any other object is recognized, repeat steps 3 and 4.
When the mal-recognition is not solved even if steps 3 and 4 are repeated, start over
from step 1.
Desirable recognition state
The shape of the sensor is almost circular.
There are no recognized areas in the
background.
Not desirable recognition state
The shape of the sensor is not circular.
There are recognized areas in the
background.
