Thi is sixth generation calibration, Version 2019
All the joints are stainless steel,Better wear resistance,When installed, The feeling of hand more smoother
It is the way of coding is 4x7 balls,then itis easier to identify, look picture. inside red ring, there are two balls that are very closer each other, This is the feature of location , You can tell which is 1,2,3,4 rod. ( patent )
The data of calibration use for expensive,famous brand laser 3d scanner,The data accuracy is 1 mm
Convenient suitcase, When it's upright, all the rods, there's no bending force
The processing by the German five axis numerical control machine tool
In total, we designed and processed 4 metal molds of balls, used for high pressure injection plastic ball. hollow white ball have two color. White and red.
In the skating and skiing project, we made the red hollow ball. So our user can see them in the white environment.
The center connector and all rigid aluminum tubes and balls are hollow, So the calibration frame very light.not easy to sag resulting to bending deformation.
Since 2003,We began to design and manufacture the DLT 3D calibration frame, and We already got a lot of design patents.
Now.we have designed many special DLT 3D calibration frames for many different science experiments.The smallest can do 6x6mm 16-25 points, the largest covers half of the basketball court,this huge calibration device,It is use for that to track the basketball's shooting,tracking the trajectory of basketball and tracking the player's trajectory of running and jumping
