6X Multispectral Sensor Reflectance Panel User Guide

1 Introduction

Welcome to the 6X Multispectral Sensor Reflectance Panel User Guide. This user guide is designed to provide documentation for people who will use 6X on a professional basis. This guide is targeted to users with an understanding of multispectral imaging and image processing.

2 Reflectance Panel Overview

A reflectance panel has known spectral properties and can be used to convert imagery to reflectance values under different lighting conditions. The process of converting imagery into reflectance values allows for time series comparisons of imagery because it normalizes the data for different lighting conditions.

Note: Reflectance panel images should be captured pre-flight, but if you forget, the images can be captured post-flight also.

3 Capture Reflectance Panel Imagery

The steps to capture reflectance panel imagery include attaching the sensor to a laptop, navigating in a web browser to the 6x configuration page, and capturing the reflectance panel images.

3.1 Connect to Laptop

To connect to a laptop:

3.2 Capture an Image

To capture an image:

1. Open a web browser on the laptop and navigate to the 6X Configuration page

http://sentera-6x.local/., as shown in Figure 5. If that doesn't work try refreshing the page or try navigating to

2. To ensure the camera is ready to go, click Capture Image, as shown in Figure 6.

4. Perform a compass calibration or other adjustments as necessary before recording reflectance panel images.

3.3 Capture Reflectance Panel Images

To record reflectance panel images:

3. When holding the sensor over the panel, avoid shadowing the panel, and try to keep the sun at your side, as opposed to in front or behind you when capturing the reflectance panel images.

4. Quickly unplug the adapter end of the ethernet cable from the drone’s sensor, and lift the drone waist-high and centered over the reflectance panel. Ensure that your shadow does not cover the panel, as shown in Figure 10.

6. To verify, navigate to the image location on your laptop, as shown in Figure 11. Refresh the page in the browser window to start a session. This session will contain images of the reflectance panel and the subsequent flight images.

7. If no image is present, ensure all of the steps were performed correctly, and if necessary, restart the process.

8. Once the images are verified, set the drone back on the ground at the launch location. 9. Pack away the reflectance panel, being sure to only handle it by the edges.

Note: You may not need to repeat this process every time you power cycle the drone or do a new flight, however, for ease of use, doing so will make sure the reflectance panel images are in the same folder as the flight data, which makes it easier to share.

10. Once the reflectance panel images have been recorded it is time to fly and the imagery can be converted to reflectance values after the flight.
