Faster more flexible ANPR from Imagsa

Imagsa’s latest Atalaya automatic number plate recognition (ANPR) camera is more flexible and has more processing power, thanks to the company’s proprietary FPGA processor coupled to a CMOS sensor which allows the camera to operate at 270 frames per second. Although Imagsa say this isn’t necessarily needed for ANPR, the camera works under any conditions and at this frame rate can accurately detect a vehicle ten times in three metres at speeds of up to 250 km/h, even in heavy rain or in direct sunlight.

65 Imagsa’s latest Atalaya automatic number plate recognition (ANPR) camera is more flexible and has more processing power, thanks to the company’s proprietary FPGA processor coupled to a CMOS sensor which allows the camera to operate at 270 frames per second.

Although Imagsa say this isn’t necessarily needed for ANPR, the camera works under any conditions and at this frame rate can accurately detect a vehicle ten times in three metres at speeds of up to 250 km/h, even in heavy rain or in direct sunlight.  By using multi-exposure and changing exposure times to enhance the area of interest, accurate OCR images are obtained, giving a 99 per cent detection rate.

With appropriate software, Atalaya is suitable for a range of applications, including spot speed detection, point to point or average speed enforcement, access control, red light violation and vehicle classification for free flow tolling.

    To complement its existing WIM offering, IRD has introduced a system to detect under-inflated and flat tyres at highway speeds. Tyre inflation pressure has both safety and economic impacts for road users and none more so than with commercial vehicles. An underinflated tyre has decreased directional control, increased risk of catastrophic failure, and negatively impacts tyre life and fuel economy.

    District 7 of Caltrans has been conducting trials to see whether the use of a single inductive loop to measure vehicle lengths and so identify heavy trucks is feasible. So far, the results have been very promising, according to Lead Transportation Engineer Steve Malkson. Between them, the adjoining ports of Los Angeles and Long Beach, the US's two biggest, cover some 10,700 acres (43km2) and 68 miles (109km) of waterfront.
