PolyPoint: High-Precision Indoor Localization with UWB
We demonstrate PolyPoint, a high-fidelity RF-based indoor localization system that achieves 28 cm accuracy indoors and tracks a fast-moving quadcopter with only 56 cm average error. PolyPoint uses ultra-wideband signals to achieve high precision RF time-of-flight estimates between nodes. To further improve accuracy, PolyPoint exploits two forms of diversity: frequency diversity, which leverages...
متن کاملHigh-precision camera distortion measurements with a "calibration harp"
This paper addresses the high-precision measurement of the distortion of a digital camera from photographs. Traditionally, this distortion is measured from photographs of a flat pattern that contains aligned elements. Nevertheless, it is nearly impossible to fabricate a very flat pattern and to validate its flatness. This fact limits the attainable measurable precisions. In contrast, it is much...
متن کاملHigh-Precision Localization Using Ground Texture
Fig. 1. System pipeline. (a) Our test robot features an NVIDIA Jetson TX1 development board, which controls a Point Grey mono camera. A light shield and ring of LEDs around the camera provide controlled lighting. (b) We first capture database images as a preprocess, and (c) stitch them into a globally consistent map. (d) Later, to locate the robot, we extract features from a query image, and (e...
متن کاملTouch Based Localization for High-Precision Manufacturing
In traditional automated manufacturing, the motions of an industry robot are programmed step by step by humans for a specific task, which is costly and timeconsuming. This greatly limits the application of industry robot when the production is relatively small. This thesis proposes two touch-based localization approaches extended from the importance-sampling particle filter for a potentially la...
