Problems solved by technology
[0003] At present, the commonly used parking space state detection methods are mainly divided into two types: one is the hardware-based parking space state detection method, which has low intelligence, high installation and maintenance costs, and poor scalability.
The other is an image-based parking space state detection technology, which analyzes the image by extracting the color model features and edge features of the parking space image to determine whether the parking space is occupied. However, the features extracted by this method are too simple and the anti-interference ability is poor.

The invention provides a parking space status detection method and a device. The method comprises the steps as follows: training a vehicle classifier based on deformable component models; calculating the detection error rate of each component model in the vehicle classifier by using the vehicle classifier to detect a plurality of positive samples; assigning different weight values to the component models in the vehicle classifier according to the calculated detection error rate to obtain a weighted vehicle classifier; and when using the weighted vehicle classifier to detect an image to be detected, adjusting the final score and final location of each component model in the image to be detected according to the result of detection, determining the vehicle position in the image to be detected according to the final score, final location and weight value of each component model, and determining the status of a parking space. With the method and the device, the vehicle detection rate is increased, and the accuracy of parking space status detection is improved.
Description
technical field [0001] The present application relates to the technical field of video surveillance, in particular to a method and device for detecting the state of a parking space. Background technique [0002] Automatic parking space status detection technology has been more and more widely used. This technology can help users to park quickly and reversely search for cars. At the same time, it is conducive to the centralized management of parking lots. [0003] At present, the commonly used parking space state detection methods are mainly divided into two types: one is the hardware-based parking space state detection method, which has low intelligence, high installation and maintenance costs, and poor scalability. The other is the image-based parking space state detection technology. By extracting the color model features and edge features of the parking space image for image analysis, it can be judged whether the parking space is occupied. However, the features extracted ...
