Survey Mapping with the Zenmuse X7 Camera

100 AGL Image comparison

I recently acquired a Zenmuse X7 camera and 16mm lens for the DJI Inspire 2.

My first task was to test the image quality between several DJI drones as follows:

Mavic Mini

Mavic Air 2

Mavic 2 Pro

Inspire 2 X5S with 15mm lens

Inspire 2 X7 with 16mm lens

I zoomed into control point 1 to test the clarity of the image.

Next I compared the X5S (15mm) with the X7 (16mm) for a single image.

X5S

Conclusion

The image quality of the X7 is slightly better than the X5S.

The real advantage between the two cameras for survey mapping purposes is the field of view and flight speed.

When comparing the "Flight Parameters" using web app for the two camera/sensors this is where the advantage is noticable.

The flight parameters are shown below:

X5S at 250 AGL FOV 87 ft for the Neat Area (shown in green)

X7 at 250 AGL FOV 110 ft for the Neat Area (shown in green)

The advantage is that with the X7 camera it takes less flight lines and can be flown faster at 16.8 mph (shown in blue) which means less batteries are needed.

In my opinion the X7 camera is worth the extra dollars if you do a lot of flying.

If you like the information provided above and would like to see more in future email posts, then consider purchasing some of my books and videos to help support the effort. As all of you know, computer hardware, software and drones costs money. I put 100% of my book/video sales back into the business to write more books, produce videos, buy drones to test and so forth.

Thank you all that have supported this effort. It is greatly appreciated.
