Abstract

According to exemplary embodiments of the present invention, the apparatus and method for measuring road flatness are provided, the method comprising obtaining an image of a road, obtaining the road flatness by dividing the image of the road into a plurality of areas, calculating an average brightness from each of the plurality of areas, and comparing the average brightness from each of the plurality of areas with a threshold, and displaying an image relative to the road flatness.

Description

technical field [0001] Teachings according to exemplary embodiments of the present invention generally relate to an apparatus and method for measuring roughness of a road surface. Background technique [0002] Recently, many devices have been provided to consumers in order to satisfy consumers' demands for satisfaction with the power performance of vehicles and convenience. An example that includes current trends is the spread of integrated display devices capable of grasping vehicle status and front / rear cameras at a glance. [0003] Driving ability can be enhanced when the driver of the vehicle is aware of potentially hazardous road conditions while the vehicle is traveling along the road. The sooner a driver recognizes a potential road hazard, the sooner he can take preventive action to avoid the potential road hazard. [0004] In this case, the driver can observe an obstacle about the vehicle that cannot be observed through the front / rear camera and the display device ...
