The image is then processed by the on-board computer, which recognizes the sign&#039;s content.<\/p>\n\n\n\n<p class=\"has-medium-font-size\">In more advanced versions, the system also uses <strong>data from GPS navigation<\/strong> and digital maps, which allows for the correction of recognized signs or the display of speed limits even if the physical sign has not yet been detected by the camera.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/images.surferseo.art\/9354aae1-0546-44f7-b384-d82a79fde4f7.jpeg\" alt=\"traffic sign recognition system - camera on the windshield\"\/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Character recognition system functions<\/strong><\/h2>\n\n\n\n<p class=\"has-medium-font-size\">The TSR system in modern cars offers a number of practical functions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-medium-font-size\">recognizes <strong>speed limit signs<\/strong>, <strong>overtaking bans<\/strong>, and the end of prohibitions,<\/li>\n\n\n\n<li class=\"has-medium-font-size\"><strong>warns the driver<\/strong>when exceeding the speed limit,<\/li>\n\n\n\n<li class=\"has-medium-font-size\">cooperates with <strong>active cruise control<\/strong> (ACC), automatically adjusting speed to regulations,<\/li>\n\n\n\n<li class=\"has-medium-font-size\">informs about the change of restrictions on <strong>head-up display<\/strong> or <strong>dashboard<\/strong>,<\/li>\n\n\n\n<li class=\"has-medium-font-size\">can cooperate with the image recording system (<strong>video recorders<\/strong>), recording the driver&#039;s violations.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/images.surferseo.art\/55072546-e9cf-4d4a-b72f-0de00ebf3c9e.jpeg\" alt=\"traffic sign recognition system - display on the dashboard \"\/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What characters does the system recognize?<\/strong><\/h2>\n\n\n\n<p class=\"has-medium-font-size\">A typical character recognition system can detect:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-medium-font-size\"><strong>speed limit signs<\/strong>, e.g. 30, 50, 90 km\/h,<\/li>\n\n\n\n<li class=\"has-medium-font-size\"><strong>overtaking bans<\/strong> and their appeals,<\/li>\n\n\n\n<li class=\"has-medium-font-size\"><strong>warning signs<\/strong> (e.g. slippery surface, roadworks),<\/li>\n\n\n\n<li class=\"has-medium-font-size\"><strong>information signs<\/strong>, such as a residential zone.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-medium-font-size\">In some models of class cars <strong>top shelf<\/strong>, these systems can even analyze <strong>temporary markings<\/strong>, e.g. during road repairs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Is the system working properly?<\/strong><\/h2>\n\n\n\n<p class=\"has-medium-font-size\"><strong>System operation<\/strong> is generally reliable, but in practice much depends on external conditions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-medium-font-size\">in case of <strong>heavy rainfall<\/strong> or snow the camera may have trouble reading,<\/li>\n\n\n\n<li class=\"has-medium-font-size\"><strong>dirty windshield<\/strong> or the camera may disrupt the functioning of the system,<\/li>\n\n\n\n<li class=\"has-medium-font-size\"><strong>illegible or misplaced characters<\/strong> may mislead the system,<\/li>\n\n\n\n<li class=\"has-medium-font-size\"><strong>temporary road signs<\/strong> (e.g. made of paper, during renovations) are often not recognized,<\/li>\n\n\n\n<li class=\"has-medium-font-size\">performance may vary depending on <strong>car manufacturer<\/strong>.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/images.surferseo.art\/8b64bd14-2009-40de-a4b6-b5dfa483c05a.jpeg\" alt=\"road sign recognition system - road renovation\"\/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Mandatory equipment or addition?<\/strong><\/h2>\n\n\n\n<p>For many car models sold in the EU, <strong>character recognition system<\/strong> became <strong>mandatory equipment<\/strong> from 2022.
