The assessment of structured light and laser scanning methods in 3D shape measurements
The development of optical 3D shape measuring methods is gaining importance as industry raises its demands in high technical performance of final products, short production times, low manufacturing costs and overall product quality. Typical example of free-form surfaces that respond to high esthetical, ergonomical and technical design is the automotive industry where product design changes on a daily basis. Since manual surface modelling requires a huge effort of time and money, this motivates further 3D optical shape measurement techniques development. Nowadays, there are two mainstream techniques that are well established with high technical and economic performance, based upon projected fringe and laser scanning methods. A short overview, and the major differences between those two methods are outlined. Advantages and disadvantages with respect to various aspects are critically observed, like sensor types, method application, data acquisition conditions, measurement range, object reflectance, automation, accuracy, spatial resolution, method maturity, measurement planning and overall measurement costs. If we extrapolate preceding development pace, it becomes clear that the application of optical shape measurement will continue to expand. There is a general trend towards universal multi-sensor and multi-data measurement systems that will potentially result in a higher level of integration of those currently competitive techniques. Such integration would result in highly versatile systems that would widen its current application potential.
