Abstract

The invention discloses a method and device for determining a boundary of a region of interest in an image and electronic equipment. The method comprises the steps that a front image, collected by theelectronic equipment installed in a vehicle, of the vehicle is acquired; two adjacent frames of front images of the front image are processed by using a frame difference method to obtain a binary image; the number of each row of white pixel points in the binary image is counted in sequence from the first row of pixel points of the binary image; according to the number of the white pixel points ineach row, a row of pixel points are selected from the binary image, and the row of pixel points are row pixel points with the number of the white pixel points in the last row being not zero in the binary image; and the lower boundary of the region of interest is determined from the front image according to the position of the selected row of pixels in the binary image.

Description

technical field [0001] The present invention relates to the technical field of image processing, and more specifically, to a method for determining a boundary of a region of interest in an image, a device for determining the boundary of a region of interest in an image, and an electronic device. Background technique [0002] As one of the fields representing artificial intelligence technology, advanced driver assistance system (advanced driver assistance system, ADAS) has always been the focus of academia and industry. ADAS includes various warning systems, such as lane departure warning system (lane departure warning system, LDWS), forward collision warning system (forward collision warning system, FCWS). [0003] Due to the high safety requirements of ADAS, the accuracy requirements of various early warning functions are relatively high. ADAS analyzes the images corresponding to the road ahead it collects and gives real-time feedback to the driver, thereby effectively avo...
