Challenges
- Evaluation of factors related to the drone camera that may cause inaccuracies when our customer uses the images to precisely reconstruct solar farms and detect anomalies.
Deliverables
- Measurement report of the distortion
- Measurement of the electronic rolling shutter at several ISO speed rating value and exposure times typically used by the customer.
Our added value
- Not all companies have the internal expertise or laboratory facilities to evaluate camera performance. We provide this expertise to our customers, offering specialized knowledge and testing services to ensure the highest image quality standards.
Outflier is a company specializing in providing drone-based solutions for solar plant inspection. They focus on using advanced imaging technologies to assist in the precise reconstruction and monitoring of solar farm infrastructure for the identification of potential anomalies. As part of their operations, it is crucial to assess any potential biases arising from camera inaccuracies.
To ensure the quality of their service, Outflier chose to collaborate with DXOMARK, a trusted expert in camera and image quality evaluation with over twenty years of experience. Consequently, we conducted measurements on the distortion and electronic rolling shutter KPIs they had defined.

About our ERS measurement
To evaluate the rolling shutter, we used the customer’s camera to capture images of our fully controllable LED timer box set to ERS measurement mode. The LED timer box displays a bright signal across vertically aligned LED lines, which sweep from left to right in sync. The software then automatically calculates the Electronic Rolling Shutter (ERS) effect from the captured image by measuring the offsets between from the top to bottom of the frame.
Many other measurement are available on our Analyzer software using our LED timer box
Our Analyzer Standard IQ software enables fast processing and effortless result export, providing instant reports with all relevant information neatly organized and professionally formatted. In this case, the customer received all the required reports within the same day.

About our distortion measurement
In the evaluation of the DJI Mavic camera, the lens was a standard spherical design, so a simple Brown-Conrady projection model was sufficient to meet the customer’s needs. However, in many other cases, we have encountered optics that are non-radial, aspherical, or require more complex models. In these situations, we employ more advanced projection models, such as the polynomial xy model, to ensure accurate results.
This highlights why working with experts like us is invaluable—our experience and expertise allow us to adapt to the specific complexities of each project, something that can be challenging to achieve independently.
