Embodiment 1

[0064] refer to Figure 1~5 , Figure 7-12 , a roadside parking space detection device based on computer vision, including a panoramic vision sensor installed on the side of the road with parking spaces, a micro-processing for analyzing the state of the parking space according to the video data of the parking space captured by the panoramic vision sensor Device 3, described panoramic vision sensor is connected with described microprocessor 3 through video interface, and described panoramic vision sensor and described microprocessor 3 are fixed on the pole 4 of road curb, as figure 1 As shown; the field of view of the panoramic vision sensor is 10 to 15 parking spaces along the road direction, basically consistent with the width of the road in terms of width, and the microprocessor includes embedded system hardware and embedded System software, described embedded system hardware comprises: CPU, video interface, storage unit, input unit, image storage unit, RAM, ROM, display un...

Embodiment 2

[0093] refer to Figure 1~4 , Figure 6-12 , in this embodiment, the adoption of the panoramic vision sensor Figure 6 The arc mirror shown in place of figure 2 The two plane mirrors shown; given that the distance from camera 1 to the arc mirror is f, the field of view of camera 1 is W×R, the installation height of the panoramic vision sensor is H, and the visual length along the road is L, The radius of curvature of the arc mirror is W, the central angle of the arc is 60°, the arc length of the arc mirror is π×W / 3, the width of the arc mirror is slightly larger than R / cos(ε-η), ε is a circle The angle between the arc mirror surface and the horizontal plane on the side view, η is the angle between the camera and the pole.

[0094] Other schemes of this embodiment are all the same as in Embodiment 1.

Abstract

The invention discloses a roadside parking space detection device based on computer vision, comprising an omnidirectional vision sensor and a microprocessor, wherein the omnidirectional vision sensor is installed at the roadside with parking spaces; the microprocessor is used for analyzing the parking space state according to the data of a parking space video shot by the omnidirectional vision sensor; and the microprocessor comprises an omnidirectional image acquisition unit, a parking space customizing module, a parking space state detection module based on a sampling point model, and a parking space state information releasing module. The invention provides the roadside parking space detection device which is based on the computer vision, has the advantages of wide detection range, highdetection precision, good detection instantaneity, high cost performance, strong environmental adaptation capability and good expandability and sustainable development, is convenient to implement andmaintain and is convenient to realize on an embedded system.

Description

technical field [0001] The invention belongs to the application of optics, computer vision technology, pattern recognition technology, embedded system software and hardware technology and intelligent transportation technology in the aspects of parking space detection on both sides of the road, parking charge management and parking guidance, especially a computer vision-based The parking lot status detection device. Background technique [0002] Today's traffic problems have become a global "urban problem", and traffic congestion is the main manifestation of the city's "traffic disease". The "cause" of urban traffic congestion stems from a variety of factors, and traffic congestion directly affects the quality of people's travel, especially those who use vehicles for transportation. The problem of "difficult parking" has become a major cause of urban traffic congestion. [0003] Statistics show that the time of motor vehicles in static traffic state is significantly longer ...
