Camera calibration has been a very important problem for 3D objects measurement technique, because it will have a impact on the measurement accuracy. Plane-based camera calibration is usually used in camera calibration. In order to solve the nonlinear optimization problem during the process of plane-based camera calibration, a new method is proposed in this paper. Firstly, the intrinsic and extrinsic...
Infrared measuring device is a device used for infrared radiation characteristic measurement. It is widely applied to each field of the military, industrial, medical, agriculture and forestry in our production life. The calibration of infrared measuring equipment directly affects the system error and the test precision of the instrument, so establish the feasible and effective calibration method,...
An approach suitable for calibrating the transverse sensitivity of accelerometer at low-frequency is presented in this work. The method proposed here employs the double turntable centrifuge as the apparatus to provide standard reference accelerations. Numerical simulation and experimental investigation are done to validate the method. Testing results of a single-axis inertial accelerometer are consistent...
For reducing the inconsistency of sensors' characteristics in laboratory and working conditions, calibration of an accelerometer with multicomponent inputs is introduced. After a review of current equipments which are capable of producing combined accelerations, we introduced a different apparatus which can offer simultaneous harmonic and constant linear accelerations. It consists of a vibration exciter...
