Whiteboard steel is typically made by applying a special type of paint to a sheet of steel. The paint is usually a type of epoxy resin that is mixed with a hardener to create a durable, glossy surface. The steel is first cleaned and treated with a primer to ensure that the paint will adhere properly. Then, the paint is applied in several layers, with each layer being allowed to dry before the next is added. The result is a smooth, non-porous surface that is resistant to stains and easy to clean.

Whiteboard steel is available in a variety of thicknesses, ranging from thin sheets that can be mounted on walls to thicker panels that can be used as freestanding whiteboards. It is also available in a range of sizes, from small desktop versions to large wall-mounted boards that can be several feet wide. Some whiteboard steel is magnetic, which allows it to be used with magnets and other magnetic accessories.
One of the advantages of whiteboard steel is that it is a very versatile material. It can be used for a wide range of applications, from simple note-taking to more complex brainstorming sessions. It is also a popular tool for teaching, as it allows teachers to write and draw diagrams that can be easily seen by their students.
Another advantage of whiteboard steel is its durability. Unlike traditional whiteboards, which can become stained and discolored over time, whiteboard steel is resistant to damage and can last for many years with proper care.
Overall, whiteboard steel is a useful and versatile material that is ideal for a wide range of applications. Its durability, ease of use, and versatility make it a popular choice for classrooms, offices, and homes alike.

One of the most common questions we get is: **"How accurate is the 3D model I created using Elios 2 visual data?"**
The answer isn’t straightforward. The accuracy of your 3D model depends largely on the quality and precision of the data you used to create it.
However, there is a general rule of thumb. The theoretical maximum accuracy for a 3D model built from visual data collected by the Elios 2 is three times the Ground Sampling Distance (GSD). Since the Elios 2 features a 4K camera, the maximum GSD you can achieve is 0.25 mm per pixel. That means the best possible accuracy for your model would be approximately 1 mm (rounding up from 0.75 mm for simplicity).
This level of accuracy is achievable when you include reference points or scale constraints close to the objects you're measuring. For example, in ideal conditions—like no backlight, non-reflective surfaces, and good texture—you can create highly accurate models.
In this video, we demonstrate how to achieve such precision by using two scale constraints and one orientation constraint across a small area. The test was conducted on a surface smaller than 0.5 square meters, which allowed us to measure objects less than 5 cm in size accurately.
Keep in mind that while 1 mm accuracy is possible, it’s not always necessary for every project. Your desired accuracy should be determined based on your specific needs. If you need precise measurements for engineering or inspection purposes, you’ll want to fly closer and collect high-quality data. But if you just need a general overview, you don’t need to worry about getting too close.
Other factors also influence accuracy, like lighting, distance from the object, and surface reflectivity. For instance, flying too far away reduces GSD resolution, which affects detail. Reflective surfaces can make image matching more difficult, lowering model quality.
The Elios 2’s unique design allows it to get extremely close to objects, making it ideal for detailed inspections. At just 30 cm away, it can capture images with a GSD as low as 0.18 mm/px.
Remember, the accuracy of your 3D model is only as good as the data you use. Planning ahead and understanding your goals will help you get the results you need.
