LPR perspective correction is a method of changing the image of a CarR device in such a way that the angle of the field of view benefits the License Plate Recognition (LPR) algorithm. The perspective correction can be utilized in scenarios where due to the position of the CarR device, license plates are being misidentified or even missed and where the external conditions are often good and constant. For example, vehicles don’t drive too fast, which makes it easier to capture the vehicle at a fixed position. The best recognition is achieved if the guidelines for CarR cameras are followed, the guidelines can be found here: /wiki/spaces/KB/pages/939851822CarR Guidelines,
However, in some situations, setting up a CarR device in such a way is not possible, for example due to architectural difficulties or enforcement of certain limitations. In these situations, the LPR perspective correction may help to create a viable image that the LPR algorithm can use. An example of an image that is taken at the entrance of a parking lot is shown in below:
