Embodiment

[0011] A system for identifying people at night while a vehicle is running, comprising the following steps:

[0012] (1) Detecting targets through a variety of sensors is conducive to more accurate detection of pedestrians. The fusion of optical sensors and infrared sensors, the fusion of optical sensors and radar sensors, and the method of information fusion of optical cameras and infrared cameras are used to detect pedestrians. Detection, the depth information of the target can be obtained through the infrared camera, so as to track the target more accurately. The radar sensor can obtain the distance and speed information more accurately in the pedestrian detection. Based on the pedestrian detection method based on radar information and image information, a pedestrian detection method is designed. Based on the infrared camera and lidar system, the information of the two is fused for pedestrian detection;

[0013] (2) In order to solve the problem of pedestrian group video de...

Abstract

The invention discloses a system for identifying person at night during vehicle driving process. The system adopts various kinds of sensors for detecting a target, is conductive to detecting pedestrians more accurately. The system comprises the steps of: inputting an original color image, carrying out edge detection on eman chain codes after performing binaryzation on the original color image, and adopting a moving average method for detecting edge contour of the image; detecting the contour by adopting a 5-rJ incremental convex hull detection algorithm based on a window to obtain a convex hull point set S; carrying out concave point mining on two adjacent points greater than a set condition in the S by utilizing a minding method based on local convex hulls to obtain a concave point set; excluding cut line segments by utilizing an effective line segment rule; and performing least square ellipse fitting on all effective line segments. The system calculates parameters according to personal appearance features monitored by an infrared probe, obtains accurate person information through utilizing an algorithm formula, helps the driver to identify, and avoids accidents at night.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a system for identifying people at night during vehicle driving. Background technique [0002] Automobiles are defined as follows: non-track-borne vehicles driven by power with 4 or more wheels, mainly used for: carrying people and or goods; traction vehicles carrying people or goods; special purposes. In 1879, German engineer Karl Benz successfully tested a two-stroke experimental engine for the first time. In October 1883, he founded the "Benz Company and Rhine Gas Engine Factory". In 1885, he made the first Benz patented motor vehicle in Mannheim. 0.9 horsepower single-stroke gasoline engine, this car has some basic features of modern cars, such as spark ignition, water cooling cycle, steel pipe frame, leaf spring suspension, rear wheel drive, front wheel steering and brake handle, etc. On January 29, 1886, German engineer Karl Benz applied for a patent for his motor vehicle. In ...
