Supplementary Road Sign Recognition

Supplementary Road Sign Recognition

By utilizing our rich experience in Optical Character Recognition, Pattern Recognition, Video Analytics and other vision based technologies we have developed a software that aids in traffic sign recognition, which is an important component of Advanced Driver Assistance Systems. Automatic identification and classification of road signs helps in directing drivers thereby ensuring a vigilant drive.

What are we up to in the Automotive Universe?

Crane Monitoring System
KritiKal built a safe load indicator unit using different sensors that monitor the system as per the configured safety limits and gather data of vital parameters.
smart helmet poc
The Smart Helmet System has in-built sensors that detect a crash and alert the family immediate contacts of the user with the GPS coordinates of the incident.
intelligent mobility
The Automotive Revolution is growing stronger with each passing year and it seems like out-of-the-box concepts won’t take long to wield their magic on the turnpike.
evehicle charger
To cut down on greenhouse gas (GHG) emissions & capitalize on renewable energy adoption, countries are leaning towards massive adoption of electric vehicles.
Electric Vehicle
KritiKal built a high voltage efficient charger that supports a universal voltage range. It comes in two variants- PFC controller-based & non-PFC controller-based charger.

Traffic Sign Recognition

By utilizing our rich experience in Optical Character Recognition, Pattern Recognition, Video Analytics and other vision based technologies we have developed a software that aids in traffic sign recognition, which is an important component of Advanced Driver Assistance Systems. Automatic identification and classification of road signs helps in directing drivers thereby ensuring a vigilant drive.

Capability

The capabilities of our Traffic Sign Recognition software include:

  • Sign identification in various lighting conditions ranging from very dark to very bright conditions

  • Detection of variable sized road signs ranging from 35×35 to 210×210

  • Detection of variable shaped road signs like Circular, Angular etc.; the shapes of the signs depend on the angle at which the images of the signs have been taken

  • Identification of variably colored road signs: Road signs like ‘No-Left Turn’, ‘No-Right turn’, and ‘Stop’ invariably appear in different shades of red color

  • Detection of low contrast input images: This could be due to motion blur, the lighting conditions etc.

Features

  • Image segmentation based on color slicing, adaptive thresholding and shape detection

  • Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) for classified sign detection

  • Color notation used to display the signs, in particular, green for ‘No-Right Turn’, blue for ‘No-Left Turn’ and red for ‘Stop’
