Abstract

The present disclosure relates to method and system for stitching frames to assist driver of a vehicle by a driver assistance system. The driver assistance system receives plurality of frames from plurality of image sensors, configured in vehicle. The driver assistance system identifies one or more objects and corresponding pixel coordinates, in plurality of frames, determine one or more set of mapped objects based on correspondence between one or more objects. The driver assistance system determines visibility status for each object in each set of mapped objects, based on pre-defined visibility conditions, identify priority index for each object in each set of mapped objects, based on visibility status and corresponding object parameters and generate resultant image by stitching pluralityof frames by considering object from each set of mapped objects having highest priority index. The resultant image is displayed to assist driver of vehicle.

Description

technical field [0001] The present invention relates generally to the field of imaging systems, more particularly but not limited to methods and systems for assisting a vehicle driver by stitching frames. Background technique [0002] Today, as multiple cameras in cars become a reality, there are applications that require stitching to stitch feeds from multiple cameras. Most existing stitching techniques are implemented using a perspective matrix (homography) between two camera scenes, and assume that the scenes are approximately planar, or that the camera centers are coincident. However, this is not the case for car cameras and the road scenes that need to be operated by them. Generally, for large vehicles such as trucks, buses, trailers, it is necessary to safely drive the vehicle in the front and rear directions. In the heading direction, the driver usually has a clear view of the path ahead. But in the opposite direction, clear visibility is impossible, and the driver...
