Live Sense SDK, a multi platform solution powered by AI, enables apps and devices to detect real-time hazards and road signs to help drivers make informed decisions. It can detect objects, on the road, in the surrounding space, and in real-time using just the edge processing on the device that can plug into any type of vehicle, regardless of internet connectivity. A complete list of features can be found here.
Live Sense core functionality of object detection and classification works for any road surface globally.
The latest version recognizes the most common road signs today, including speed limits, stop signs and hazard signs. For a detailed list, refer to this developer guide. Our current SDK version most accurately identifies speed limit signs posted in regions where the signs are similar to signs in North America, Europe, Oceania, SEA and Brazil. Contact HERE support if you would like to have Live Sense increase its coverage.
Live Sense SDK uses the CPU, GPU and processor to run the AI models and to process the detections. We recommend to plug in your device if you plan to use it for longer periods.
The performance of the SDK depends on how good the lighting condition is and how clear the sign is. The SDK does function in low light or at night provided the object or sign is illuminated well.

The confidence is defined as the surety or accuracy with which a certain object / sign is recognized by a machine learning model. Low confidence value might lead to more false positives where the model recognizes incorrect objects. Very high confidence value means the model will recognize objects / signs very much identical to those used for its training and might ignore few similar kinds. We recommend to have a minimum confidence value of 0.6 (60%) for our models. A detailed list of each model and its recommended confidence value can be found in Models.
1) Check the minimum confidence value. It should be set to a value between 0.6 and 0.9.
2) Point your camera to the images given in Example App section based on which model is being tested.
3) Try to run the camera in both landscape and portrait orientation.
