Magnetic AprilTags

Our new magnetic AprilTags at a glance

AprilTags are used as visual reference markers. They are often used in photogrammetry, robotics and augmented reality applications. AprilTag detection software calculates the orientation and identity of the tag relative to the camera. This is used to calculate the exact 3D position. AprilTags are suitable for a wide range of lighting conditions and viewing angles.

If you want to know more about the background and the different applications of AprilTags, you can find more information about the topic and a detailed test of our development department here.

By the way, our magnetic AprilTags are available in two versions: the slightly flexible magnetic AprilTags for flat, metallic surfaces and the magnetic AprilTag plates. The latter are particularly suitable for uneven or curved objects or surfaces.

AprilTags for flat surfaces

Our AprilTags type 36h11 can be easily fixed to a wide variety of places thanks to their magnetic property. Any flat metallic surface is perfect for easily attaching AprilTags to it, no matter how the weather is. There are 20 pieces in each set. The flexible plates with magnetic backing are especially lightweight, weighing 46 grams. The targets are available in 10x10cm and 15x15cm sizes; the plate dimensions are 11x13.5cm and 16x20cm, respectively. The numbers 0-19 are printed in each set.

AprilTag plates for curved surfaces

As can be seen in the pictures, AprilTag plates are particularly suitable for curved and uneven surfaces. Thanks to the extremely light and strong magnetic plates, the AprilTag code remains flat and readable even on uneven surfaces. The AprilTag plates have the same dimensions as the flexible AprilTags, but are slightly thicker than the flexible ones, with a plate thickness of 3.5mm instead of 1.2mm. However, with their weight of 53 grams each, these plates are also lightweight. Again, there are 20 pieces in each set. The AprilTags correspond to type 36h11 and contain the imprinted numbers 0-19.
