Accurate calibration remote control calibrator for DIC detection system

Technical Field

The utility model relates to a DIC detecting system, concretely relates to DIC detecting system accurate calibration remote control calibrator belongs to the optical measurement mechanics field.

Background

DIC (Digital image correlation), also called Digital speckle correlation, is a Digital image correlation method, which obtains deformation information of a region of interest by correlating two Digital images before and after deformation of a test piece. The basic principle is that the interesting region in the image before deformation is subjected to grid division, each sub-region is taken as rigid motion, then correlation calculation is carried out on each sub-region according to a predefined correlation function through a certain search method, the position of the sub-region after deformation is searched in the image after deformation, further the displacement of the sub-region is obtained, all the sub-regions are calculated, and the deformation information of the whole field can be obtained.

Before the DIC camera starts to capture images, calibration must be carried out through a special calibration plate, namely, a DIC system captures images of the calibration plate and calculates to obtain camera parameters, the calibration process usually needs to place the calibration plate with a certain size at a position where an object needs to be measured, the calibration plate is rotated to different angles to take pictures, the operation is repeated for multiple times until the system prompts that calibration is successful, and the calibration plate is an important component which is about the accuracy of the DIC detection system.

At present, aiming at the calibration of a DIC detection system, a calibration plate is generally manually held to rotate by different angles at a position to be calibrated so as to facilitate the capture and calibration of a DIC camera, but in the environment of some special spaces and narrow spaces or the position to be calibrated in a closed space, the original calibration method is not easy to complete the calibration action. In order to overcome the technical problem, the common method is to open a box door or move a DIC camera for calibration, which is time-consuming and labor-consuming, and can change the original calibration environment and reduce the calibration precision of the DIC.
