Publication number: 20230306216Abstract: A method, a software application, and a reader for evaluating a matrix code in an image, in which the patterns of the individual symbol rows are reconstructed, and scanning values are determined at the intersections of the symbol row patterns. Firstly, the approximate position of each of the symbols along the symbol rows in the direction of a first dimension of the image is determined successively, with the determined pixel positions being used as the position of the symbols in the direction of the first dimension, and subsequently the patterns of the individual symbol rows along the other dimension of the complete image are determined successively. These two steps are then repeated for the other dimension. The scanning points are determined on the basis of the properties of the data modulation taking into consideration the channel distortions. A decorrelation of the scanned symbols reduceS the local inter-symbol interferences.Type: ApplicationFiled: July 22, 2021Publication date: September 28, 2023Applicant: TECHNISCHE UNIVERSITÄT DORTMUNDInventors: JIANSHUANG XU, CHRISTIAN BRAUERS, RUEDIGER KAYS, JOHANNES KLEIN

Patent number: 10325506Abstract: A method for monitoring an airspace includes a first control and detection system and a second control and detection system. The first control and detection system has a first flying device and a first control and detection unit, and the second control and detection system has a second flying device and a second control and detection unit. An airspace monitoring system is different from the first control and detection unit and also from the second control and detection unit. First data relating to the first flying device is transmitted from the first control and detection unit to the airspace monitoring system, and data based on the first data is transmitted from the airspace monitoring system to the second control and detection unit. In this manner, the method allows a system-independent airspace monitoring process.Type: GrantFiled: April 8, 2015Date of Patent: June 18, 2019Assignee: TECHNISCHE UNIVERSITÄT DORTMUNDInventors: Niklas Goddemeier, Sebastian Rohde, Christian Wietfeld
