  • So we create marker (it is an array of same size as that of original image, but with int32 datatype) and label the regions inside it. The regions we know for sure (whether foreground or background) are labelled with any positive integers, but different integers, and the area we don’t know for sure are just left as zero.

  • for ChArUco marker detection and pose estimation. 1. Introduction In this paper, we refer to computer-vision-friendly 2D patterns that are unique and have enough points for 6DoF pose estimation as fiducials or markers. ArUco mark-ers [12, 6] and their derivatives, namely ChArUco mark-ers, are frequently used in augmented reality and robotics.

  • The size of the aruco marker is pre-determined, so that the distance between the drone and the marker can be calculated based on how large or small the marker appears in the frame. Using the dronekit and openCV libraries in python, this entire process can be easily accomplished.

  • Obtaining models that capture imaging markers relevant for disease progression and treatment monitoring is challenging. Models are typically based on large amounts of data with annotated examples of known markers aiming at automating detection. High annotation effort and the limitation to a vocabulary of known markers limit the power of such approaches. Here, we perform unsupervised learning ...

  • Hello, I am trying to detect Aruco markers using OpenCV. At first I tried a logitech USB webcam and it worked ok, but the resolution was small and the framerate was slow. I couldn't set the resolution higher even though the camera natively supports it.
  • Sep 12, 2017 · This is probably because you are executing the code with Python 3 instead of Python 2. The problem is that in Python 3 map returns an iterable object of type map, and not a subscriptible list. To solve it, you can either use Python 2 or force the result of the map into a list by changing, in line 14 of objloader_simple.py,
