Knoxville, Tenn. (PRWEB) August 29, 2012
Today Perceptics announced that its License Plate Recognition (LPR) systems installed at U.S. land border crossings perform with greater than 95% accuracy. The performance data for each port of entry is regularly published as part of the Western Hemisphere Travel Initiative (WHTI) agreement. Under the agreement, Perceptics regularly assesses the accuracy of its license plate readers by determining if the non-excluded read rates of the LPRs are meeting the contractual requirement of 95% accuracy. An LPR read result is considered correct only if all the alphanumeric characters and the state, province or country of the license plate are correctly identified. To measure read rates, misread results are grouped into read errors and exclusions. Read errors are misreads that should have been read correctly by the LPR. Rejected reads are misreads that can be explained due to factors outside the LPR specification such as a damaged, obstructed plate or missing license plates. Typical exclusion rates have been found to be less than 5%, while average correct accuracy rates have been measured to be greater than 95%.
In some inbound port of entry locations Perceptics’ License Plate Readers are posting plates reads at an astounding 98% accuracy. And at the largest southern port of entry, Perceptics’ LPR systems consistently read both retro-reflective and non-retro-reflective plates at 97% accuracy. Outbound lane data is equally impressive with some locations reporting up to 99% accuracy at highway speeds. “We are excited to know that our LPR systems can consistently perform to the desired specifications of U.S. Customs and Border Protection,” says Perceptics’ president Orlando Carrasco. “These reports serve to remind us of the value our systems bring at securing our nation’s borders and encourage us to extend to our customers the very best in technology and ongoing support”, Carrasco continues.
For over 30-years, Perceptics License Plate Readers have been reading state identification on all plate types any time of day or night and in any weather conditions. Our LPR Systems and Under Vehicle Inspection Systems have been deployed in thousands of vehicle lanes worldwide, including the United States, Canada, Mexico, United Arab Emirates, Saudi Arabia, Malaysia, and Singapore.
