Abstract

The invention provides a tolerance correction device and method of an AVM system. According to one embodiment of the invention, the tolerance correction device comprises an image input part which converts image signals obtained when a camera installed on a vehicle shoots round patterns around a vehicle to camera image data; and a tolerance correction part which extracts ovals corresponding to the round patterns from the camera image data, calculates a homography between the camera image data and top view images according to the correlativity between the ovals and the round patterns, and calculates the external parameters of the camera to determine the position of the camera in world coordinates.

Description

technical field [0001] The invention relates to a tolerance correction device and method for an AVM system. Background technique [0002] Usually, the vision of the driver sitting inside the vehicle is mainly towards the front, and the left, right and rear vision of the driver are partially blocked by the vehicle body, so they have very limited vision. [0003] In order to solve the above-mentioned problems, vision aids such as side mirrors are usually used to compensate for the driver's limited field of vision. The recent trend is that technology including camera means is used in vehicles to capture images of the outside of the vehicle and provide them to the driver. [0004] Among them, there is an AVM (Around View Monitoring) (hereinafter referred to as AVM), that is, a plurality of cameras are installed around the current vehicle to display a 360° all-round image around the vehicle. The AVM system not only provides a single view captured by multiple cameras around the v...
