The automobile industry is challenged with finding an easy, reliable, fast and cost-effective method to analyze the outcomes of crash tests. Two companies have now joined forces to provide an innovative solution.
Mantis Vision, a company well known for its fast, accurate and robust 3D handheld scanners, is the provider of the hardware and the general 3D software.
TEC Competence is a start-up focusing on sensor applications, product development and software applications.
This unique solution has integrated the TEC application software directly into the Mantis scanning software, enabling the entire process – from scanning through the end result – to be streamlined within the Mantis Echo software. No third-party software or time-consuming data transfers or data format changes are required. The entire process is executed through a single workflow, which is easy to learn and simple to handle.
The solution can be applied directly at the crash site. A comparison between the simulated setting (e.g. dummy position) can be carried out just before the crash.
The application can be used by the car manufacturer as well as by a third-party crash lab. The main task of the application is to deliver the 3D point cloud of the crash car in the car/simulation coordinate system for further evaluation.
The car manufacturer, which already has the vehicle in its simulation coordinate system, provides a OBC/CSV file with the target coordinates.
For third-party crash labs that do not have the OBC/CSV file with the target coordinates, the application can be used in two ways:
Alignment using 2D markers. The car is scanned before the crash; the targets are automatically detected and the coordinates are stored. After the crash, the targets will be detected again and the coordinates will be replaced by the target coordinates taken before the crash.
The second option is for the targets to be placed on known positions on the car, representing the car coordinate system. And enabling the same process to be performed. The end result is that the 3D point cloud can be delivered in the car coordinate system for further evaluation.
Bringing a new car model to market is a time-consuming and cost-intensive process. Executing crash tests to meet safety regulations is an important part of this process. Computer simulations of crash scenarios are a popular method used to keep crash test costs down. While simulations cannot fully replace actual crash tests, the industry has moved from 2D to 3D data capturing and replaced single point measurements with full 3D point cloud for higher accuracy data evaluations of the crash tests.
This application was developed in cooperation with a major car manufacturer and the aim is to integrate the scanning process into the crash test procedure.
The aim is for a crash site operator with good technical skills to operate the scanner and produce first results right at the crash site. After a crash test and the scanning, the operator should be able to state that all relevant data has been captured and that the crash site can be cleaned and prepared for the next test.
