Abstract:
In the present invention, a chart installed on a road is photographed from a certain distance, camera resolution is calculated by analyzing a photographed image, and warning output and autonomous driving level decrease processing are executed in accordance with the calculation result. An image analysis unit selects a photographed image at a timing when a reference line is detected from images photographed by a camera as a resolution analysis image. A resolution calculation unit calculates resolution of the photographed image with use of a resolution analysis chart image included in the resolution analysis image selected by the image analysis unit. A resolution analysis chart is installed on a road on which a mobile apparatus travels, the reference line is drawn on the road to be separated from the resolution analysis chart by a certain distance, and highly accurate calculation of resolution of the photographed image based on the image obtained by photographing the chart from a certain distance becomes possible.
