Object Detection Using Skewed Polygons Suitable For Parking Space Detection
A neural network may be used to determine corner points of a skewed polygon (e.g., as displacement values to anchor box corner points) that accurately delineate a region in an image that defines a parking space. Further, the neural network may output confidence values predicting likelihoods that corner points of an anchor box correspond to an entrance to the parking spot. The confidence values may be used to select a subset of the corner points of the anchor box and/or skewed polygon in order to define the entrance to the parking spot. A minimum aggregate distance between corner points of a skewed polygon predicted using the CNN(s) and ground truth corner points of a parking spot may be used simplify a determination as to whether an anchor box should be used as a positive sample for training.
IMAGE PROCESSING APPARATUS AND METHOD
An image processing apparatus includes a conversion unit, a generation unit, and a processing unit. The conversion unit is configured to convert an original image received from a plurality of cameras into a top view image. The generation unit is configured to generate a surround view monitor (SVM) image by synthesizing a bottom image extracted from the top view image and a wall image extracted from the original image. The processing unit is configured to generate a modified SVM image by adjusting an area of the bottom image and an area of the wall image according to an adjustment condition, and to process the generated image into a display signal.

IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD
An image processing device is equipped with a marker detector, an oblique line detector, and a parking frame detector. The marker detector extracts, from an image, positive and negative edge segments that are aligned next to each other at a predetermined interval as a pair, and detects a parking space division marker based on the pair. The oblique line detector detects an edge on one side of an edge segment (single-edge segment) that is not extracted as the pair, and detects a presumed straight line based on the single-edge segment connected with an oblique line. The parking frame detector detects neighboring edge segments based on the positive and negative edge segments as well as the single-edge segment of the presumed straight line, and detects a parking space based on a distance between the neighboring edge segments.
