This tool can help you build boolean queries suitable for doing a broad search for different synonyms or spellings of each word. Start via the drop-down below or just start typing in the search field.
{{ row.typeTitle }}: ( )

Since our index often lack the full first name of people it can be difficult to correctly search by author.

Fill in the fields and let us help you build a good query:

If you need to find everything possible, consider only searching by last name.

Use "Starting year" to ignore publications out of year range.

Vision-based Positioning for UAVs

Hu, Xiao

Technical University of Denmark — 2021

the sensitivity of magnetic sensors prohibits the placement of electronic positioning sensors directly on the bird. This work focuses on developing a vision-based positioning solution that employs computer vision and sensor fusion techniques. The solution relies on a camera and GNSS/IMU mounted on the UAV

Vision-based UAV Positioning Method Assisted by Relative Attitude Classification

Zhang, Sheng; Li, Jie; Yang, Chengwei; Yang, Yu; Hu, Xiaolin

Proceedings of the 2020 5th International Conference on Mathematics and Artificial Intelligence — 2020, pp. 154-160

to improve the anti-interference of the UAV cluster flight, it's necessary to use a positioning method which is based on visual information. Based on the above analysis, this paper proposes a vision-based UAV positioning method assisted by attitude classification. Firstly, the problem of solving the relative

or visual odometry would fail. We present the complete solution, including the temporal/spatial alignment of the GNSS/INS system and camera, front-end vision-based detection and tracking, and back-end position estimation and optimization. For performance evaluation, we use a commercial GNSS/INS system
