About Edge Vision

EV-Accidents is a plugin that transforms any camera into a car accident detector with a single toggle. EV-Accidents notifies an operator of a collision within 10 seconds, decreasing reaction time down to 3 minutes instead of 10 minutes on average.

Key features:
– Captures an image of an accident
– Shows the precise time of an accident event
– Shows confidence level of an event
– Sends a notification to the operator via NX events
– Can send captured accidents for further accuracy increasing
– Configurable confidence threshold for events
– Real-time plugin adaptation

Technical possibilities and restriction:
– The system aims to detect accidents on crossroads as main accident place.
– The system is able to detect an accident with 70+% accuracy during the first runtime stage.
– To improve the quality of detection plugin is set to share positive predictions with a data center on EdgeVision side. During 3 months of runtime, we will upload a specific version of the plugin with accuracy 85+%. So, the host should be connected to the Internet in order to transfer frames of detection.
– Parameters of the plugin can be tuned to increase the accuracy of systems with a variety of cameras.
-Host with Intel Core i5 and 8 GB RAM successfully deals with operating on 2 cameras simultaneously.
– The resolution of a video stream from the camera should be at least 640×480 for normal plugin operation.
– The system works in real-time mode and sends a notification to an operator within 1 second in most situations.
