Crash Test Imaging

With the help of high-speed cameras automotive safety experts are able to gather more data that informs them of how to advance their vehicle designs. In order to make each crash as efficient as possible it is important that operators understand the basics behind the unique needs of automotive imaging.  Decisions such as on- or off-board camera placement, lighting, and field of view options all affect they type of information that will be gathered.  This whitepaper breaks down those concerns with tips and tricks for improving crash tests. 


Phantom C320J
Miro C320J

The Phantom Miro C320J and C320 are perfect HD high-speed, low cost crash test cameras. They are small and rugged, with very high light sensitivity for on-board testing.

DIGITAL IMAGE CORELATION

Digital image correlation (DIC) in automotive testing can help with understanding how stress affects construction materials and how vibration can wear on components. Phantom cameras excel in multi-camera setups where observations need to be synchronized for complete data capture.

COMBUSTION

Combustion concerns in automotive research can determine the efficiency of an engine and with the proper data encourage advancements in engine technology. Phantom cameras have the high dynamic range necessary to capture combustion events.

MICROFLUIDICS

Microfluidics study in automotive situations can enhance fuel efficiency, engine performance, and a variety of other internal component functions that require liquid to move quickly through tightly packed components. Enhancing how automobiles perform increase customer safety and satisfaction. Phantom cameras have interchangeable lens mount options to allow for a variety of application uses.

WORKFLOW

Workflow processes are important to automotive testing. Researchers must understand what options are available and what type of setup will best benefit their needs.  Phantom cameras have a complete automotive setup via the J-box system but other options are available if they fit the application being tested. 


FIND THE RIGHT HIGH-SPEED CAMERA

High-speed cameras are found throughout the automotive industry, and each application has different needs. Safety crash testing involves both on-board and off-board scenarios, can be complex and require extreme efficiency to manage multiple tests a day from multiple cameras. To get the best system for your facility, it helps to think beyond the individual cameras and consider the following questions:

  • What is the preferred workflow for the crash tests?
  • What is the maximum number of cameras needed on-board and off? How will they be networked, sync’d and controlled?
  • How will the images from the test be safely backed up, stored and shared?
  • How would you rate your facility’s lighting? Can a more light sensitive camera help?
  • How busy is the facility? Are the technicians skilled in photography?

Component Testing: Each application has slightly different requirements and it helps to understand the many camera capabilities and features that are available. For example, inside and around an instrument panel or door assembly could benefit from a specialty miniature camera the size of a golf ball. A fuel injection study could benefit from a very high frame rate camera model at 10-100,000fps.

Airbag Testing: This is especially challenging due to the speed of the event and the bright white of the bag. The most appropriate camera depends on the level of detail that needs to be analyzed. Ultrahigh-speed cameras with high frame rates may be required to catch the most subtle motions and timing. Cameras with high dynamic range, for example, will help mitigate against the sudden bright white of the airbag, allowing to capture the subtle shades within the white.

Deformation testing with Digital Image Correlation (DIC) is a powerful tool for automotive engineering teams to understand deformation and stress in items from tires to hoods. DIC can measure deformation and stress without tedious sensors with only 2 high-speed cameras and software. Depending on application need and programming experience, a number of open source software packages may suffice. Combustion testing is a critical component of engine design and high-speed cameras can provide detailed understanding of the impacts of minute design adjustments.

Combustion testing typically requires very high frame rates found in the Ultrahigh-speed models and specialized supplemental lighting.

Regardless of what you are recording, the above will always be important. Please do not hesitate to contact us so that a trained Phantom camera expert can assist you in deciding which camera you will need.
