Face recognition systems identifies the driver of the vehicle and assigns all events to that particular driver.
Also, this information is taken into consideration when calculating the Event(s) scores.
When the driver is recognized, The Camera can trigger a "Face Recognized" Event
- This is an optional feature (the default settings are for this event to be disabled)
- The Event is uploaded on the idrive cloud system "iris" via cellular data by default
Face Recognition will be performed in the following circumstances:
- At Ignition ON
- When someone requests a Live Look in from a selected vehicle in iris>GPS Interface
Driver Face Detection
The detection of the driver face is based on the selected "driving side" (IRIS->Fleet Manager-> Vehicles).
- 1. Left driving side (is considered default) - The Camera will perform a Face Detection over the whole image and will analyze the face closest to the edge of the side that the driver is supposed to be. That face is considered driver face if the median of the face is placed in the correct half of the driver selected position (see below).
- 1. Left driving side (is considered default) - The Camera will perform a Face Detection over the whole image and will analyze the face closest to the edge of the side that the driver is supposed to be. That face is considered driver face if the median of the face is placed in the correct half of the driver selected position (see below).
- 2. Right driving side. Camera will perform a face detection over the whole image and will analyze the face closest to the edge of the part that the driver is supposed to be. That face is considered driver face if the median of the face is placed in the correct half of the driver selected position (see below).
- 2. Right driving side. Camera will perform a face detection over the whole image and will analyze the face closest to the edge of the part that the driver is supposed to be. That face is considered driver face if the median of the face is placed in the correct half of the driver selected position (see below).
- 3. Middle: This is a particular case when the camera will consider the detection closest to the center of the whole image
- 3. Middle: This is a particular case when the camera will consider the detection closest to the center of the whole image
Face Recognition Process
The face recognition process requires a cooperation from the fleet managers until the system learns all drivers faces but is does NOT require cooperation from the drivers.
In case of face unrecognized, the camera will upload the detected face in Idrive Cloud (see image below). During a session (Ignition On / Ignition Off), the camera will upload maximum 3 faces in cloud.
The managers will have a section in the IRIS platform where they will be able to assign each face to a driver.
At the next request, the cloud will be able to recognize the driver. The camera will not upload the face anymore; instead will add the detected face in the camera storage together with the driver information obtained from cloud.
At the next ignition ON, the camera will try to recognize itself the driver by using the faces from the local storage (Idrive Cloud will become the second option).
Based on the above mechanism, each camera will be able to recognize all persons that are usually driving the car (in different conditions) and the cloud will not be used anymore.
When the recognition happens on the server, a template is sent to the server for analysis and then the response is sent back to the camera. The transactions delay can in rare cases lead to face recognition video events with an empty car or with another driver if the switches happened exactly after the recognition or the driver leaves the car exactly after the recognition.
