Thermalyze Version 7 Support for IS320 Cameras
Differences Between Thermalyze v7 and v6
Camera Link Video Board
Thermalyze v7 can retrieve thermal image data from both the Optotherm IS320 and IS640 thermal imaging cameras using a Matrox eCL Base Camera Link video board that is installed in a PCIe computer slot. Thermalyze v6 can retrieve thermal image data only from the IS320 thermal imaging camera using a National Instruments 1426 Base Camera Link video board that is installed in a PCI computer slot. Therefore, in order to acquire thermal images in Thermalyze v7 from an IS320 camera, a computer with an available PCIe slot is required.
Image File Format
Thermalyze v7 is a 64-bit application and stores images in a non-proprietary binary format with .oimg extension. Thermalyze v6 is a 32-bit application and stores images in a proprietary PNG format with .png extension. Thermalyze v6 utilizes the 32-bit NI Vision image processing software library to store images and is unable to run in the 64-bit application space of Thermalyze v7.
Opening v6 Image Files in v7
Converting v6 Files
In order to open .png image files saved in v6 within Thermalyze v7, they must first be converted to binary format using the Optotherm 32-bit application named FileConvert (see figure 1 below).

FileConvert converts .png image files used in Thermalyze v6 to binary image files used in Thermalyze v7. Converted binary files have .ocon extension and are saved in a folder named “ConvertedFiles” that is automatically created by FileConvert in the same directory as the .png file being converted. Individual files can be converted or all files within a selected folder can be converted, including files in nested folders.
Note: Emissivity tables, sequence images, and MBC project files must also be converted as they all contain .png image files.
