Understanding Reference Images

The reference images that come with this product can help you quickly evaluate features or provide a starting point for developing on the QNX Platform for ADAS and experimenting with various features.

The provided reference images typically contain a subset of the supported features for a specific hardware platform. You can download the reference image you want from the QNX Software Center. After the image is installed, you can find in the $QNX_BASE/targetImages/adas directory on your host system, where $QNX_BASE is the directory you installed the QNX Platform for ADAS.

Note: These reference images are large, so ensure you have sufficient diskspace on your system before you install it from the QNX Software Center.

After you install the reference image, you can follow the Getting Started guide for that platform to get image running on your target board. For more information about the guides that matches the images you installed, see “Reference images available.”

In some cases, the reference image doesn't run a feature by default. In some cases, you'll simply augment the image to support that feature. In others, you may need to import a library, do some additional development, and then build a new image. For information about building your own image, see Working with Target Images guide for this product.

Note: Your board hardware may not support all available features. For example, if a specific board doesn't support USB, then USB cameras won't be supported. See the Reference image sensor support chapter in this book for more information.

Before you decide which reference image is the best to use as a starting point for your development, we recommend that you review the following sections:

“Reference images available”, which summarizes the available reference images for this release. The hardware platform you choose should be as close to a match as possible in terms of hardware specifications (hardware processor architecture, vendor, GPU, etc.) with your production hardware platform.
“Feature availability by hardware platform”, which summarizes the features and capabilities each reference image has. Unless noted, all features are supported on all hardware platforms in this release.
“Reference image sensor support”, which summarizes the various cameras, lidar, radar, and GPS systems that are supported on each reference image. Depending on the connectors available for each hardware platform, some boards might not support all cameras or sensors. In some cases, a CAN-to-USB or Serial-to-USB adapter is required. Sensor and camera support should match what you plan to use in production, such as radar, lidar, GPS, or camera systems.
“Reference image vision-processing support”, which summarizes the vision-processing software that is integrated with the reference image. Unless noted otherwise, this vision-processing software and the algorithms it provides are supported on all hardware platforms in this release.
