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...
MODULAR BUNDLE ADJUSTMENT FOR PHOTOGRAMMETRIC COMPUTATIONS
Bundle adjustment Camera model Analytical Jacobians Software Photogrammetry Tilt-shift lens
2018/6/4
In this paper we investigate how the residuals in bundle adjustment can be split into a composition of simple functions. According to the chain rule, the Jacobian (linearisation) of the residual can b...
