3D models of scan of car seat textile
Car seats are complicated assemblies of headrests, foam components, slides and frames. They need to be ergonomically well designed to offer plenty support to the driver and deliver an optimal driving experience. Simultaneously, they need to comply with a range of safety regulations.
After going through great lengths to make sure that their seats are comfortable across their intended range of operation, car seat manufacturers want their seats to look great as well! When the upholstery process is finished, each seat needs to be inspected to guarantee the absence of wrinkles and foils in the fabric or leather covers, and the correct positioning and alignment of all seams.
Vision++ performed a feasibility study for a leading global seat manufacturer to investigate the usability of 3D vision for the automated inspection of car seat covers. A prototype 3D scanning solution was built, and a SW pipeline – based on proprietary 3D vision components – was developed to demonstrate the potential of the technology. The results are shown in the pictures below.
The 3D inspection solution’s features in a nutshell:
- Vision technology: 3D laser line triangulation.
- Precise and repeatable sub-mm accurate 3D scanning.
- 3D scanning of both leather and textile seat covers, irrespective of their color.
- Quantitative analysis of relative height/depth of foils and wrinkles.
- Automatic alarm generation when the seat cover’s geometry deviates beyond pre-set size and depth related tolerances.
