This work describes a camera-based method for the calibration of optical See-Through Glasses (STGs). A new technique is introduced calibrating every single display pixel STGs in order to overcome disadvantages parametric model. non-parametric model compared one has advantage that it can also map arbitrary distortions. The generation using waveguide-based displays [5] will have higher distortions due characteristics their optics. First tests show better accuracies than previous works. By...
In the field of smart metering it can be observed that standardized protocol, like Wireless M-Bus or ZigBee, enjoy a rapidly increasing popularity. For protocol implementations, however, up to now, mostly legacy engineering processes and technologies are used, modern approaches such as model driven design open software platform disregarded. Therefore, within WiMBex project, shall demonstrated is possible develop commercial class implementation following state-of-the art process using TinyOS...
As increasing the clock frequency leads to unmanageable heat and power dissipation search is on for another way get more efficient faster embedded systems. Given that chip area also a constraint, we investigate addition of custom instruction processor set which enables execution an complex division. The designed hardware divider numbers receives four input values returns two output values. data bandwidth constraint 2 inputs 1 loosened by making multicycle as described in previous work. We...
This work describes a non-parametric camera-based method for the calibration of Optical See-Through Glasses (OSTG). Existing works model optical system through perspective projection and parametric functions. In border areas displays such models are often inadequate. Moreover, rigid patterns, that produce only small amount non-equidistant point correspondences, used. order to overcome these disadvantages every single display pixel is calibrated individually. The error prone user interaction...
We present a pipelined 32-bit Instruction Set Extension (ISE) for complex valued floating point operations. The ISE was implemented in the NIOS II processor, and constraint on number of inputs outputs register bank overcome by distributing reads writes instruction over several cycles. hardware size reduced sharing between instructions. main contribution this work is that designed performs division, multiplication, addition subtraction numbers. Comparing use embedded multiplier divider...
Nowadays, robotic systems are an integral part of many orthopedic interventions. Stationary robots improve the accuracy but also require adapted surgical workflows. Handheld devices (HHRDs), however, easily integrated into existing workflows and represent a more economical solution. Their limited range motion is compensated by dexterity surgeon. This work presents control algorithms for HHRDs with multiple degrees freedom (DOF). These protect pre- or intraoperatively defined regions from...
