The latest portable measuring systems provide users with a range of Handy solutions. HandyPROBE, from Creaform, fills the gap between portable measuring arms and laser trackers.
It consists of 2 elements – the small, lightweight handheld HandyPROBE, plus the high accuracy C-Track camera positioning system. The C-Track uses photogrammetry techniques to accurately track and establish the position and orientation of the HandyPROBE in real-time. The C-Track can be mounted on a simple lightweight tripod or anywhere that it can see the object to be measured, and includes an integrated wireless communication with the HandyPROBE. The whole measuring system is packaged in a single transport case that can be easily be moved around by one person, and fits in the back of a family hatchback car, with setup time achieved in a few minutes.
In order to achieve high accuracy in real manufacturing environments, C-Track incorporates a dynamic alignment system, whereby the HandyPROBE, C-Track positioning device and the part can be moved at any time. This is achieved through the use of reference markers attached to the part being measured, which means the coordinate reference system is attached directly to the part. Unlike portable arms or laser trackers, where the measuring reference is the measuring device itself, this totally eliminates the need for complex “leap-frog” calculations and highly stable setups with clamped parts, thereby removing the possibility of human error and massively improving flexibility, efficiency, accuracy, and above all ease-of-use.
The handheld HandyPROBE is a completely arm-free measuring probe, with absolutely no moving parts to completely eliminate the possibility of mechanical wear. As the system provides the user with 100% portability, this guarantees rapid execution of 3D inspection and reverse engineering tasks in all environments, thereby ensuring reliable measurement data. Standard CMM-like stylus configurations, which can be quickly changed without the need for re-calibration, enable users to measure all types of features, including those that would normally be inaccessible due to line of sight or limited reach of an arm.
