I am using LabVIEW Vision Express for lens calibration (Distortion model grid) of a telecentric lens arrangement and I am using edmund optics multi-frequency grid for calibration. After generating a calibration template, whenever I try to reuse the calibrated template for calibration of newly acquired images, I am not able to edit the template after loading it. The "Edit Template" option remains disabled after importing an existing template. I am using LabVIEW 2016(32 bit) version. I have tried the same process on LabVIEW 2015 version and it seems to work perfectly on that version. Could anyone please help me with this.
