Some superconducting magnets research at IMP (Institute of Modern Physics, CAS, Lanzhou) will be described in this paper. Firstly, a superconducting electron cyclotron resonance ion source (SECRAL) was successfully built to produce intense beams of highly charged heavy ions for Heavy Ion Research Facility in Lanzhou (HIRFL). An innovation design of SECRAL is that the three axial solenoid coils are...
In this paper, we present a homography-based method for calibrating the central catadioptric vision system. We consider two cases, i.e. orthographic camera with parabolic mirror and perspective camera with hyperbolic mirror. In both cases, the parameters of the mirror and the extrinsic parameters of the camera are estimated simultaneously, assuming that the intrinsic parameters of the camera are known...
In this paper, we talk about a technique for dynamic calibration of the relative pose in our structured light system with possibly varying intrinsic parameters. Assuming that there is an arbitrary planar structure in the scene, we suggest a two-step method for dynamic calibrating the relative pose between the camera and the projector. First, the translation vector is computed geometrically from the...
In this paper, we present a new method for automatic recalibration of the relative pose in a structured light system by a single image of planar surface. Assuming that the intrinsic parameters of the camera and the projector are known from initial calibration, we show that their relative orientation and position can be determined automatically from four projection correspondences in an image and a...
