Method and system for counting number of people in car

Abstract

The invention discloses a method and system for counting the number of people in a car. The method comprises the following steps: 1. obtaining an internal image of an empty car; 2. marking seat sections on the internal image of the empty car to form a background image; and 3. obtaining a current internal image of the car, comparing the current internal image with the background image to obtain difference of each seat section, and if the difference meet a preset standard, judging that a person is on the seat. The system comprises an image device used for obtaining the internal image of the car, a marking device used for marking the seat sections on the internal image of the empty car and forming the background image, a comparing device used for comparing the obtained current internal image of the car with the background image and obtaining the difference of each seat section and a counting device used for counting according to the difference and the preset standard. The method and system of the invention perform people counting to each seat section, thus avoiding the blocking between passengers and the blocking between passengers and seats.

Description

technical field [0001] The invention relates to image analysis and processing technology, in particular to a system for counting the number of people inside a vehicle. Background technique [0002] At this stage, there are mainly two technologies for people counting. One is to install infrared detection devices in vehicle entrances and exits to detect and count the number of people entering and exiting at the entrances and exits. The other is to install cameras at the entrances and exits to detect and count the number of people entering and exiting the entrances and exits by detecting and counting the movement and shape features of objects. These two technical solutions can count the number of people going in and out at the entrance and exit. [0003] Image-based counting of people at entrances and exits is used for counting the number of people inside larger vehicles. The advantage of image-based counting is that the cost is low, and it can make good use of the image acqui...

Problems solved by technology

However, occlusion between passengers and between passengers and seats is a serious problem

In addition, because of the accuracy range of the camera and the focal length of the camera, it is difficult to count the number of people at a distance; and complex actual conditions, such as lighting, people's posture and the changeable external characteristics of people, make the number of people in the car Counting is harder
