The overall sensitivity consists of five levels: -2 , -1 , A , +1 , +2 . The A setting is the middle of all overall sensitivity settings and is used normally. Use the +side (+1 and +2) to increase the sensitivity and the –side (-2 and -1) to reduce the sensitivity.
4.10. [Image processing] icon [Image processing] allows you to set the image processing for the scan result displayed at the idle state. (The setting made by this icon is valid only for the scan result dispayed at the idle state. After starting a new scan, the setting for the measurement is restored to the original device setting.. For the setting as the devie setting, refer to Section 4.11.4 Device setting: [Image processing] menu.) For the available image processing, refer to Section 4.
4.10.1. Image processing The original scan data includes always unnecessary reflected signals (for example, the reflection wave from the concrete surface (surface reflection wave) or reflection wave from the boundary of concrete layers) which is commonly distributed over the scan image. These unnecessary reflection waves make the image decoding difficult.
4.10.2. Fixed surface processing This image processing subtracts the predefined data of the typical concrete surface reflection wave from the displayed scan data. Usually it can reduce the concrete surface reflection wave to provide easy image decoding. The predefined data used in this image processing is called the fixed surface reflection wave which is generated at the factory by using typical concrete and is stored in the non-volatile memory of the sensor unit.
2)Select a position 3) Image processing setup screen ) ) 1) Complete a scan ) ) ) Here the registration of a user surface wave data has been completed. The label of [Image processing] icon shows USER as the current setting. 4)Select user surface wave Image processing 5) Tap [OK]. 6) Tap [OK].
Note y The data file in the data storage contains the raw scan data, the image processing setting, and the fixed surface wave data used in the image processing. When the data is recalled from the data file, the scan result image is displayed by using the recalled data (raw scan data, the image processing setting, and the fixed surface wave data).
4.10.4. Subtraction This image processing is used to reduce the horizontal band noise of the reflection wave appearing at the depth more than 20 cm as shown Figure 4-16 1). You can use this image processing with the procedure below. (1) Scan the concrete. After the scan completed, the scan image is displayed on the main screen. (2) Move the cursor to the area on the scan result image where you want to do the processing.
) 4) Tap [OK]. 5) Image after processing Figure 4-16 Subtraction (1/2) Note y When tapping [OK] without the mark 9 at [□Processed at the current cursor] at the step 4) above, a message “No processing point defined” appears and the processing is canceled.
4.10.5. Manual surface processing This image processing is used to reduce the remained noise even after an image processing (Refer to Figure 4-17 1)) . This image processing subtracts the registered surface reflection wave from the scan result only for the depth range of 0 mm to 200 mm. You can perform this image processing with the following procedure. (1) Scan the concrete. After the scan completed, the scan image is displayed on the main screen.
) 4) Tap [OK]. 5) Image after processing Figure 4-17 Manual surface processing (1/2) Note y When tapping [OK] without the mark 9 at [□Processed at the current cursor] at the step 4) above, a message “No processing point defined” appears and the processing is canceled.
4.10.6. Averaging This image processing is effective to reduce the horizontal line noise appearing uniformly over the scan result. It subtracts the averaged wave of all scan points from the scan result and displays the processed image. This processing may remove the continuous reflection signal appearing at the constant depth like the reflection from the opposite side of the concrete wall. Use this processing by considering this point. You can perform the average processing by the following procedure.
4.10.7. Peak processing This image processing is effective to remove the unwanted image caused by the ringing in the reflection wave from the detected object (steel bar) and to show the refection wave only from the detected target. Use this processing when the depth of the detected object is difficult to read due to the images of the ringing. This processing is not applicable to the detection of the object (ex. cavity) with the relative permittivity lower than that of the concrete.
4.10.8. Original image The original image shows the image of the raw scan result for which no image processing is applied.
4.11. Parameter setup screen ) The parameter setup screen allows you to set various conditions: relative permittivity and sensitivity used in the scanning, and so on.
