Here’s a smart scan for security checks

Jaya Shroff Hindustan Times New Delhi, April 25

TWO FORMER Indian Institute of Technology (IIT) students have come up with a smart and easy solution for carrying out high security vehicular checks using high-end computer vision technologies.

Kapil Bardeja and Anoop Prabhu have developed Zen-Scan, a smart scan security system that can examine the underside of a vehicle with utmost accuracy. The scan-system can be installed at premises that faces high security threats and is adept at detecting unwanted substances like bombs, explosives and contrabands.

“It uses high end electro-mechanical and camera based assembly,” Bardeja said. Triple cameras capture several images as a car passes through the system embedded in the floor. The images are bundled up together as a composite whole and then calibrated with the use of multiple sensors to fit the required size. The image can also be enlarged up to 16 times in order to get a bigger and clearer picture.

“Right now mirrors are used to detect threats coming by way of vehicles, which involves manual labour and is a tedious and inaccurate process,” said Bardeja.

“This will not just smoothen checking but is reliable, fast and efficient,” he added. The device can store more than one lakh entries and records other relevant data like time, date and the make of the vehicle. The data can then be used for further investigations if the need arises.

The two techies formed KritiKal SecureScan Private Limited, which works towards building vehicle security systems. The company is a subsidiary of a team called KritiKal Solutions Private limited that was formed as part of the Incubation Program at IIT-Delhi in 2002.

ZenScan^TM on way

Sunday, 29 January 2006

KritiKal SecureScan Private Ltd (KSPL) of India is to launch an advanced vehicle scanner system called the “ZenScan^TM” in Sri Lanka shortly. In an interview with the Sunday Observer, Chief Executive Officer of KSPL Kapil Bardeja explained the advantages and the innovative features of the system.“ZenScan^TM” is a computer vision based system to image the underside of the moving vehicle. It uses high end electro-mechanical and camera based assembly", he said.

"This system could be installed at any premises that faces high security threat", added Bardeja. "The video grabbed by the system is stitched to form a composite image of the underside of the vehicle. Potential applications include inspection of vehicle underside for presence and detection of unwanted substances like bombs, explosives, contraband things, etc."

"The image is displayed on a monitor. It can be controlled by the operator to change the appearance of the image or zoom into selected areas to examine in more details" he said.

Using hand-held mirror is the most common method to search for hidden items under a vehicle at present. Bardeja, stressing that it's completely unfair to compare the “ZenScan^TM” system to the mirror system, pointed out that the mirror system consumed a lot of time and large man-power was required for that.

But & “ZenScan^TM” system scans a moving vehicle up to a speed of 30km/h and the visuals and details obtained through the scanning could be stored for desired duration, he noted.

Asked as to how much it would cost to install the system he said it'd be roughly around 45-50 thousand US dollars. There will be a range of prices depending on the requirement of the organisation, that is willing to purchase the foot, he added. Bardeja also noted that the technology of their invention was purely indigenous and it had gotten a good reception in India. "We are basically targeting the developing countries", he further said.

The KSPL hopes to launch this product in the third week of February, according to Bardeja.

UN resolution expires.
