Embodiment

[0024] A system for identifying people while a vehicle is running, comprising the following steps:

[0025] (1) Obtaining the background image: the background image is obtained by averaging the sequence images of the moving target running for a period of time:

[0026] B ( x , y ) = 1 N Σ i = 1 N I i ( x , y )

[0027] B(x,y) represents the background image, I i (x, y) represents the gray value of the i-th frame sequence image at the pixel point (x, y), and N represents the number of frames;

[0028] (2) Get the foreground image:

[0029] m i (x,y)=I i (x,y)-B i (x,y)

[0030] where I i (x, y) represents the gray value of the pixel at the...

Abstract

The invention discloses a system for identifying a person in a vehicle driving process. The system comprises the following steps of: obtaining a background image; obtaining a foreground image; obtaining pedestrian features; and detecting and calculating pedestrians. The system is capable of accurately and automatically identifying the person, so that a driver can take measures conveniently, the problems of safety accidents caused by the fact that the person cannot be seen clearly due to vehicle driving speed or road environment limitation are reduced, and the driving safety is ensured.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to a system for identifying people 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 Nov...
