Problems solved by technology

Second, illegal parking is the culprit of scratching traffic accidents
Third, illegal parking becomes the target of theft
Fifth, illegal parking becomes an obstacle on the sidewalk
[0016] Based on the research of the above-mentioned existing technologies, it is found that the existing visual detection methods usually need to perform global processing such as background modeling, grayscale processing, edge detection or foreground detection on the entire image obtained by the camera. The method will inevitably affect the real-time performance of the detection, and requires a lot of storage resources and computing resources; it is very difficult to realize the miniaturization and light weight of the illegal parking detection device

Embodiment 1

[0086] refer to figure 1 , 2 , 5-11, a light-weight panoramic vision-based parking violation detection device, including high-definition cameras installed at various measurement points on the road, and the high-definition cameras are arranged at about 10 meters above the roadside lane, and The direction of the lane is parallel to the lane, and the horizontal axis of the imaging plane of the high-definition camera is parallel to the ground plane, as shown in the attached figure 1 shown.

[0087] The microprocessor that is used for carrying out illegal parking detection according to the video data of high-definition camera, described microprocessor comprises microprocessor system hardware and microprocessor software, it is characterized in that: described microprocessor hardware is made up of CPU, image Memory, input unit, storage unit, voice playback unit, communication unit, video interface, RAM (Random Access Memory) and ROM (Read-only Memory), as attached Figure 7 As s...

Embodiment 2

[0138] refer to Figure 3 ~ Figure 11 , as another preferred solution: install the high-definition camera on the side of the road, as attached image 3 Shown; HD video camera adopts panoramic vision sensor, and described panoramic vision sensor is made of two mirrors forming an angle and a camera facing the mirror; the angle between the two mirrors is 180°-2γ, and the two The width value of the mirror surface on the front view is W, the height value on the side view is R, and the width value W and the height value R of the two mirror surfaces are located within the imaging range of the camera; on the side view, the center of the camera The axis forms an angle η with the central axis of the vertical pole, and the mirror surface forms an ε angle with the road side of the horizontal plane; The central axis is parallel, and the focal length of the camera is f;

[0139] The installation height of the panoramic vision sensor is H, the visual range of the road along the road is L, ...

Embodiment 3

[0145] Refer to attached Figures 9 to 11 , the rest is the same as implementation 1 and implementation 2, the difference is that the customization of roadside lanes, the automatic generation of sampling points and the detection of illegal parking analysis are completed on two different devices; among them, the customization of roadside lanes, sampling The automatic generation of points is completed on the PC, and the analysis and processing detection of illegal parking is completed on the embedded device; the SOCKET communication method is used between the customized PC and the embedded device for analysis, processing and detection, as shown in the attached Figure 9 Shown; The specific implementation method is: at first the roadside lane information and the sampling point information on the roadside lane that PC has customized, the processing flow of lane customization and generation sampling point is as attached Figure 11 shown; then, through SOCKET communication to the em...

Abstract

The invention discloses a lightweight peccancy parking detection device based on full view vision. The device comprises a full view vision sensor which is used for acquiring a video image of a wide range monitoring zone and a microprocessor which is used for analyzing and understanding the video image and carrying out peccancy parking detection. A high definition camera is connected with the microprocessor through a video interface, and carries out real-time vision detection on vehicles on a road. When the behavior of peccancy parking is detected in a vision detection range, a peccancy parking driver is told or warned not to carry out peccancy parking through a voice playing unit. If the parking time exceeds a specified time threshold, a system snapshots a peccancy vehicle, and automatically generate a peccancy parking record. According to the invention, a video image detection method which uses points to replace a side is used to reduce spatial redundancy, thus lightweight peccancy parking vision detection is realized.

Description

technical field [0001] The invention belongs to the application of panoramic vision sensor technology, computer vision technology, image recognition technology and network communication technology in the field of intelligent transportation, especially the application in the detection of illegal parking on roads. Background technique [0002] With the rapid development of our country's national economy, the rapid increase in the number of motor vehicles has led to a series of problems such as traffic congestion caused by the excessive growth of traffic demand. Among them, the phenomenon of illegal parking of motor vehicles is an important factor causing traffic congestion. [0003] According to the investigation of the traffic control department, illegal parking of motor vehicles mainly has five major hazards: First, illegal parking becomes the source of traffic congestion. Second, illegal parking becomes the culprit of scratching traffic accidents. According to statistics, ...
