The goal was to produce photo realistic images that could
replace traditional photography for marketing literature.
We decided to use a V5 Perceptron laser scanner on the end of a 7 axis Romer Cimcore arm as the area to be scanned was particularly large. This gave two distinct advantages:
The Cimcore arm is one of the most accurate articulating arms on the market. This means that the positional accuracy of the laser anywhere within 3.6m measuring volume can be guaranteed to less than 0.070mm.
The V5 Perceptron laser scanner has arguably the widest band width of all handheld scanners on the market place and has a data collection rate of 458,000 pts per second. This means the operator has a large ‘paintbrush’ to scan over the car and therefore the data can be collected quickly.
The exterior of the car was scanned, taking less than one day to digitise the whole shape including the wheels, brake discs, lights and front grill. This attention to detail meant that when the marketing company received the file they would have maximum resolution in all details of the car where traditional photography would focus.
The point cloud collected was processed in Polyworks software to produce a triangular surface mesh which could be exported into third party software for post processing.
The result mesh file from Polyworks was converted into quad surfaces and rendered to produce brochure images used in advertising and print. The real advantage to the customer during this process is the time and money saved compared to traditional photography processes. The cars can be visualised in any 3D scene or environment and colours and trims can be changed in an instant.
