Embodiment Construction

[0063] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0064]The discriminant method of the open state of the high beam of the night driving vehicle based on the morphological feature of the present invention comprises the following steps:

[0065] Step 1. Obtain an image that can clearly distinguish the shape of the car light

[0066] By setting appropriate exposure parameters, light source supplementary light, highlight suppression, infrared imaging, polarization filtering and other technical means for the camera or camera, the clear capture of the shape characteristics of the illuminant in the headlight area of ​​​​vehicles driving at night is realized.

[0067] Such as figure 1 , figure 2 As shown, the images are captured for the shape features of the illuminant in the headlight area of ​​the vehicles of the two embodiments (low beam and high beam states).

[0068] Step 2. Binarize the ca...

Abstract

The invention discloses an on-state judging method of headlights on full beam of night-driving cars based on morphological characteristics. The on-state judging method includes: step 1, capturing images which can obviously judge headlight shapes, step 2, performing binarization processing on the captured images, step 3, performing erosion processing on the images subjected to binarization processing, step 4, labelling the effect images subjected to erosion processing, step 5, eliminating connected domain of the labeled images in a small area, step 6, performing connected domain merge processing on the effect images subjected to small-area connected domain elimination, step 7, detecting headlight array shapes, and step 8, judging on-states of headlights of the same car. The on-state judging method can judge the on-state of the headlights on full beam of the night-driving cars based on the morphological characteristics.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic monitoring, and relates to a method for judging the on-state of high beam lights of vehicles driving at night based on morphological features. Background technique [0002] With the rapid development of road traffic, vehicle traffic safety has become an important issue of global concern. As an important means of monitoring and analyzing traffic safety conditions and collecting evidence for traffic administrative law enforcement in intelligent transportation systems, video surveillance mode has been widely used. For vehicles driving at night, the correct use of car lights is the basis for drivers to drive safely. However, at present, the phenomenon of indiscriminately turning on high beams is quite serious. Illegal use of high beams on well-illuminated city streets will cause dazzling or "instantaneous blindness" to oncoming drivers, produce visual errors, and easily cause traffic acci...
