What you need to know when choosing a high-end imaging solution
When selecting a premium imaging solution, various factors need to be taken into consideration. Image quality
Ultra-high resolution to see the smallest details
The term ‘high resolution’ is often used for two very different things: The size of the pixels and the number of pixels.?
The size of the pixels defines the smallest details that can be seen. This aspect focuses on the scale of individual pixels in relation to the ground or object being imaged. Terms such as Ground Sampling Distance (GSD), ground resolution, or pixel size
The term ‘image size’ defines how many pixels are in each image. For example, 921,600 pixels in a standard 720p video frame or 151,301,008 pixels in an image from a Phase One 150MP iXM camera.?
It is crucial to consider the necessary level of detail in image capture. For instance, when assessing the condition of a wind turbine blade, the ability to clearly identify minute cracks or other indications of wear and tear is paramount.??
Understanding the influence of pixel size is essential when selecting the optimal camera and lens for any application, to ensure they will meet the specific requirements of the task at hand.??
When the required pixel size is known, it is important to consider how big an area can be covered by each image at that ground resolution.?
Why is this important?
By using a camera with a larger image size, it is possible to cover a large area with the required pixel size, using fewer images. This not only reduces the total number of images required but directly translates to a higher number of assets inspected or a bigger area mapped per day, significantly boosting productivity and resource utilization.?
High-quality pixels
We want high ground resolution to get the right level of detail and we need a large image size to get high productivity.?

Additionally, pixel quality is important for the overall image quality. There are again many aspects to this. Some of the key parameters of pixel quality are:??
Inspections are often done in bright sunlight, which can make it challenging to see all the details in both the brightest and darkest areas. Phase One cameras feature low noise and a high dynamic range to deliver usable images regardless of light levels.
Additionally, Phase One’s RAWimage format – Intelligent Image Quality (IIQ) – is unique. Essentially, we refrain from doing any processing of the data during the initial capture. Unlike many other cameras that process the data immediately upon capture, our approach preserves all the information captured by the image sensor. This is particularly crucial as the processing and compression applied by other cameras results in irreversible data loss.

Quality: Why it makes a difference
When considering the use of Phase One cameras for mapping missions, the ability to capture very large images in an ultra-high quality means getting more done in less time. It’s a direct gateway to productivity savings. This is one of the major reasons why customers choose us.?
In the context of aerial inspections, ensuring accurate data acquisition with high productivity, even in challenging light conditions, is imperative. It is also crucial that the captured image data is not processed or compressed in the camera, allowing AI-driven analysis to perform to its full potential.??

11 个月You are making misleading statements by talking about pixel size. Pixel size does not change. A pixel is a pixel is a pixel. A pixel is a picture element made up of red, green and blue and value data. What is important is the number of pixels in an image not the size of the pixel. The number of pixels in an image is referred to as Resolution. I agree it is important to have a camera & optics that capture the most pixels, but the size of a pixel never changes. Digital camera sensors capture image data. That captured data can be manipulated using Capture One and output in a pixel raster image. Please don't dumb this down.
