DEVELOPMENT OF A SINGLE-VIEW ODOMETER BASED ON PHOTOGRAMMETRIC BUNDLE ADJUSTMENT
Single-view odometer Photogrammetry Bundle Adjustment Scale Calibration KITTI Community
2018/6/5
Recently, a vehicle is equipped with various sensors, which aim smart and autonomous functions. Single-view odometer estimates its pose using a monoscopic camera mounted on a vehicle. It was generally...
THE PERFORMANCE ANALYSIS OF AN AKF BASED TIGHTLY-COUPLED INS/GPS INTEGRATED POSITIONING AND ORIENTATION SCHEME WITH ODOMETER AND NON-HOLONOMIC CONSTRAINTS
INS GPS Tightly-coupled AKF non-holonomic constraints
2014/4/29
INS/GPS integration scheme can overcome the shortcoming of GPS or INS alone to provide superior performance, thus this study implements a tightly-coupled INS/GPS integration scheme using AKF as the co...
在GPS/INS车辆组合导航中，GPS信号易受外界干扰而失锁。针对INS单独导航误差迅速累积的问题，在利用速度先验信息辅助INS导航的基础上，加入Odometer观测信息，提高了系统的可观测性和导航精度；另外提出了改进的位置修正法，即不直接利用状态估值修正位置，而是用修正后的速度推算位置。实测算例结果表明，与INS单独导航相比较，采用速度先验信息，提高了载体速度精度，采用改进的位置修正方法，位置精...
Evaluation of Distance Measurement Accuracy by Odometer for Pipelines Pigs
Odometer Perimeter INS pipeline
2009/7/28
High precision is essential in the localization of anomalies (laminations, corrugations, corrosion, stress, blows, etc.) by the pig inspection device in any pipeline. The problem of distance measurem...
