Educational test bench for attitude control of 1U Cubesats
Bonilla López, Antoni; González Díez, David; Voltas Aguilar, Jordi; Gago Barrio, Javier
In this paper, we present a test bench intended to test attitude control of 1U Cubesats. This platform, based in air bearing principle, is intended for educational purposes. It is designed according to the principles of modularity, low costs and usability. We have built the frame and the cubesat model using additive manufacturing techniques. Our design is affordable, easy to reproduce and based in COTS. We also present a basic 1U cubesat frame that fits inside a sphere, allowing a full 360º movement around all axis. The cubesat model is equipped with reaction wheels and manetorquers.

A crucial aspect for selecting optimal areas for commercial advertising is the probability with which that publicity will be seen. This paper presents a method based on top-view camera measurement, where the probability of viewing is estimated based on the trajectories and movements of the heads of the passerby individuals in the area of interest. Using a camera with a depth sensor, the heads of the people in the range of view can be detected and modeled. That allows to determine the orientation of the head which is used to estimate the direction of vision. A tracking by detection algorithm allows to compute the trajectory of each user. The attention given at each advertising spot is estimated based on the trajectories and head orientations of the individuals in the area of interest.

The quantification of the attention received by advertisements is of paramount importance to determine its effectiveness. In this work, a simple and effective objective method for the assessment of the attention given to advertisements is provided. The proposed method is based on computing the oriented trajectory of the different test persons along with their head pose. This way, it is possible to determine if a given person is looking towards the advertisement. While other similar methods use more complex setups, requiring a camera at each advertisement location, our method needs only a single (or a few) ceiling camera. Even though the apparent simplicity, the method can compute attention measures at each point of the scene.
