Problems solved by technology

The AGV intelligent parking system can effectively alleviate the problem of difficult parking. However, the parking status in the interactive area of ​​the system is various. When the automatic parking robot does not reach the vicinity of the vehicle, it is difficult to quickly judge the vehicle only by the sensors installed on itself. The specific position in the interaction area and the oblique angle of the vehicle body will affect the working efficiency of the system
In addition, because the interaction area of ​​the parking system is also affected by environmental conditions, the normal working space of the parking robot is limited, and the parking robot cannot get into the bottom of the car anyway, which means that certain parking states of the vehicle, For example, if the body tilt angle is too large, the body exceeds the working boundary of the interaction area, etc., it will affect the normal operation of the system.

Embodiment Construction

[0044] Further description will be given below in conjunction with specific examples.

[0045] see figure 1 As shown, the visual detection method of the parking behavior in the interactive zone of the AGV intelligent parking system provided by this embodiment includes the following steps:

[0046] Step 1: Collect the video information including the complete interactive area of ​​the AGV intelligent parking system from a bird’s-eye view through the camera set directly above the interactive area of ​​the AGV intelligent parking system, and transmit the video information to the computer, and then through the image enhancement on the computer The technique preprocesses the video frame images. Image preprocessing methods include image grayscale, histogram equalization, etc.

[0047] Step 2: Extract the background of the image through mixed Gaussian modeling, and use the background difference method to separate the foreground image, and perform morphological processing, shadow det...

Abstract

The invention discloses a visual detection method for parking behavior in an interactive area of ​​an AGV intelligent parking system. Extract and analyze information such as angle and body position, realize effective identification of various parking behaviors, and make a judgment on whether the parking behavior of the vehicle is regulated, and provide effective information for the handling of the vehicle by the automatic parking robot, thereby effectively improving AGV. Intelligent level of parking system management.

Description

technical field [0001] The invention relates to the technical field of design and management of an intelligent parking system, in particular to a visual detection method for parking behavior in an interactive area of ​​an AGV intelligent parking system. Background technique [0002] At present, with the rapid growth of the number of motor vehicles in the country, the problem of difficult parking has become increasingly prominent. The AGV intelligent parking system can effectively alleviate the problem of difficult parking. However, the parking status in the interactive area of ​​the system is various. When the automatic parking robot does not reach the vicinity of the vehicle, it is difficult to quickly judge the vehicle only by the sensors installed on itself. The specific position in the interaction area and the oblique angle of the vehicle body will affect the working efficiency of the system. In addition, because the interaction area of ​​the parking system is also affe...
