Guidance device, guidance method, and guidance program
Abstract:
A mark object that serves as a marker for a guidance point on a set route is specified, and coloration information related to a coloration of the mark object is acquired. Based on the coloration information, a correction information creating object before the mark object on the route having a coloration similar to the coloration of the mark object is specified. An image of the correction information creating object while a vehicle travels the route is acquired as a correcting image, and color correction information is calculated based on acquired color information and existing color information. A recognition template is then corrected based on the calculated color correction information to create a correction template. Thus, because the recognition template used for recognizing the mark object is corrected to a color more closely resembling the actual appearance of the mark object, the recognition accuracy of the mark object can be improved.
