TEMA 3DTEMA 3D produces 3D coordinates from a set of 2D image sequences where the different sensors are placed at different locations. To coordinate the image sequences in time, the cameras can either be synchronized during imaging or they can have a common time base tagged to each frame in each sequence. To provide the spatial calibration, four or preferably five fixed targets are needed in any one frame that can be seen by all cameras. Then the x, y, z coordinates of these points are loaded into the program and each camera location is back calculated, knowing the camera focal lengths. Other features are:
With this software and with as few as two cameras and four fixed targets, a full 3D analysis can be carried out on any number of moving targets. All the other standard features of the basic 2D software are available in this module:
TEMA Wand Calibration is the brand new calibration tool for 3D analysis of crash tests, sled tests
By combining multiple high-speed cameras and TEMA Wand Calibration it is possible to do a Click the images to enlarge TEMA 2D demonstration video.
