Gravio can infer camera images using TensorFlow , a Google system used for Artificial Intelligence and Machine Learning. Two types of TensorFlow files are available:
- TensorFlow and
There is a difference in the number of deep learning layers in the inference process:
- TensorFlow has 32 layers and
- TensorFlowLite has 16 layers
While TensorFlow is more accurate in inference, it requires more processing time and memory. We suggest that you verify with your environmental conditions such as lighting, contrast, camera resolution etc. if the TensorFlowLite model is sufficient.
Available Inference Files
The following inference files can be used in Gravio per default:
Recognition of congestion
|Approximate distance||Inference file name|
Recognizes the degree of congestion in the area (range) captured by the camera.
16Feet, 32Feet, and 48Feet are approximate distances to the area recognized by the camera.
48Feet is a wider range than 16Feet, so please use the larger number to identify people in the distance.
Outputs: Integer of number of people detected (counting heads, optimised for an indoor setting.)
Number of people counting
This inference counts the number of people recognized by the camera.
Outputs: Integer of number of people detected (counting full bodies, optimised for an outdoor setting.)
Recognizes the weather in the sky recognized by the camera.
Outputs: windy, thunder, cloudy, typhoon, snowy, sunny, rainy, unknown
If you have a free or basic subscription, you get the Enterprise subscription, you can upload your own AI/ML models and push them to the Gravio HubKits.
