Bidirectional real-time vehicle chassis image synthetic method based on linear array type camera

Abstract

The invention provides a bidirectional real-time vehicle chassis image synthetic method based on a linear array type camera. According to the method, real-time data analysis and splicing comprises steps that, (1), after splicing signals are received, each frame of images of the linear array type camera is acquired and stored to a temporary file till the splicing signals end; (2), Sobel operators are utilized to calculate whether each image has effective content, paths of effective images are stored to an array; (3), according to the image paths of the array, the images are spliced to one synthesis chassis picture; and (4), a resolution and a proportion of the synthesis picture are adjusted. Through the method, most application scene requirements are satisfied, vehicle chassis splicing can be automatically realized in real time, detection missing can be avoided, vehicle chassis image completeness can be realized, sharpness is high, the resolution rate can reach multiple millions of pixels, bidirectional real-time splicing is supported, and the method is suitable for multiple application scenes.

Description

technical field [0001] The invention relates to a vehicle chassis image splicing synthesis method, in particular to a real-time vehicle chassis image splicing method based on a line array camera data frame sequence. Background technique [0002] At present, the entrance and exit vehicle passages of prisons, detention centers, drug rehabilitation centers and other places of detention mainly rely on the police to conduct manual searches when conducting security inspections on the chassis of entering and exiting vehicles, which is laborious and time-consuming. Due to the wide variety of motor vehicle chassis, inspectors are required to have a considerable understanding of various vehicle chassis, and they need to have rich experience in inspection and be more serious and responsible. Generally, inspectors will check slowly and easily cause missed inspections. At present, even if a small number of units have installed monitoring on the ground in the inspection area of ​​the entr...
