[0029] The present invention will be further described in detail below in conjunction with the drawings and embodiments:
[0030] figure 2 It is a schematic diagram of the image acquisition of the parking space detection method of the present invention, which is mainly for fixed acquisition of images. As shown in the figure, the above-mentioned parking space detection system based on identifiable marks is set in the parking lot, including image acquisition components, images The processing component and the display output component, the image acquisition component is arranged on the fixing member, and the image acquisition component is connected with the image processing component and the display output component through a wire.
[0031] Because the above-mentioned image acquisition component can collect the image information of the parking space in the parking lot, the image information finally enters the image processing component connected to it. After processing, it provides whether the parking space is occupied or not according to the detection result of the identifiable mark. Related Information.
[0032] In a preferred embodiment, the image acquisition component can be a camera 1 commonly used in the market. Since the camera 1 has the function of automatically acquiring images, it can well collect and monitor the parking conditions in the parking lot in real time.
[0033] In the embodiment, the fixing member selects a support column 3 with a certain height, and the camera 1 is fixed on the platform 2 on the support column 3, and the platform 2 can be mounted on the support column 3 through a control device connected to it. Rotation and movement of a certain range and angle are performed on the upper surface, whereby real-time images in a larger range can be obtained.
[0034] In addition, in order to obtain better image collection and detection results, the detection system needs to be set up multiple, preferably around the parking lot. In the actual layout, you can refer to the parking lot and the optical capture effect of the camera 1. , So that multiple collection and detection systems can obtain the overall status of the parking spaces in the parking lot, so that the collected data can be comprehensive and accurate.
[0035] In addition, in order to achieve a better reference detection effect, we choose to set one or more recognizable marks 4 at the parking space, for example, letters or patterns written or placed in the parking space. When selecting the identifiable mark 4, as long as it can achieve: the empty parking space and the parking state can be clearly distinguished. Generally, we can directly use the paint to spray a specific digital pattern on the ground of the parking space to meet the requirements. Effect.
[0036] image 3 It is a schematic diagram of image collection of another embodiment of the parking space detection method of the present invention.
[0037] As shown in the figure, in this embodiment, the camera 1 can rotate around and collect image information at a large angle, which can realize 360-degree rotation on the support column 3 through the platform 2 and scan the parking lot space. Of course, this technical effect can also be adopted by arranging multiple cameras 1 on one support column 3 that cannot achieve 360-degree rotation, and similar effects can also be achieved.
[0038] In addition, in order to obtain better image collection and detection results, the detection system needs to be set up multiple, preferably around the parking lot. In the actual layout, you can refer to the parking lot and the optical capture effect of the camera 1. , So that multiple collection and detection systems can obtain the overall status of the parking spaces in the parking lot, so that the collected data can be comprehensive and accurate.
[0039] Figure 4 It is a schematic diagram of image collection of another embodiment of the parking space detection method of the present invention. As shown in the figure, the parking space detection system based on identifiable marks of the present invention is set in a parking lot, and includes an image acquisition component, an image processing component, and a display output component. The rope used to translate the image processing component is arranged at a spatial position above the parking lot, and the image acquisition component is connected to the image processing component and the display output component through a line.
[0040] Since the above-mentioned image acquisition component can collect the image information of the parking space in the parking lot, the image information finally enters the image processing component connected to it, and after processing, can provide whether the parking space is occupied and other related information.
[0041] In a preferred embodiment, the image acquisition component can be a camera 1 commonly used in the market. Since the camera 1 has the function of automatically acquiring images, it can well monitor the parking conditions in the parking lot in real time.
[0042] In the embodiment, the camera 1 and the pan-tilt 2 are fixed together, and the pan-tilt 2 is installed on the rope 5, and the pan-tilt 2 can realize the function of panning and collecting images on the rope 5 through the control component. In addition, the pan-tilt 2 may not be connected to the control component, and the technical effect of controlling its translation can be achieved through the built-in control component.
[0043] After the above-mentioned camera 1 is designed, it can move in a certain range, so that real-time images of parking spaces in a parking lot within a larger range can be obtained.
[0044] In addition, in order to obtain better image collection and detection results, the detection system needs to be set up multiple, preferably around the parking lot. In the actual layout, you can refer to the parking lot and the optical capture effect of the camera 1. , So that multiple collection and detection systems can obtain the overall status of the parking spaces in the parking lot, so that the collected data can be comprehensive and accurate.
[0045] In addition, the above-mentioned rope 5 can also be directly fixed on a fixable object in a parking lot or an underground garage without using the support column 3, and this technical solution is simpler.
[0046] In addition, in the above two embodiments, the image acquisition component can also be a zoom camera (for example, a common camera on the market), and the image processing component is a single-chip microcomputer or a computer device with an operating system, which is used to realize parking marking Detection and identification.
[0047] We can better realize the parking space detection function of the present invention by virtue of the excellent image recognition and processing functions of the above-mentioned image processing components.
[0048] In addition, the above-mentioned device can also be connected to a storage component (for example, a large-capacity hard disk), which can realize status monitoring and storage functions, and further realize the technical purpose of historical query.
[0049] In the following, we will give a detailed description of the parking space detection method based on identifiable marks of the present invention.
[0050] figure 1 It is a flowchart of a specific embodiment of the parking space detection method of the present invention.
[0051] As shown in the figure, the present invention mainly includes the following steps:
[0052] Step 1: Set an identifiable mark representing the parking space in each parking area.
[0053] We generally place identifiable marks on the parking spaces in advance; generally, the identifiable marks are words or patterns placed or written on the parking spaces. In addition, the text or pattern contains specific location information indicating the parking space.
[0054] Moreover, in order to achieve the effect of distinguishing and recognizing, we choose that when the recognizable device is parked in the parking space of the corresponding position, the recognizable mark can be completely covered, and will not be covered by the image acquisition component (for example, The camera) collects, and then affects the purpose of the present invention.
[0055] Step 2: Collect the image of the above parking area and convert it into a digital image;
[0056] According to the distribution of parking spaces, we set up image acquisition components and auxiliary equipment connected with them on the parking lot; then, reuse Figure 2 ~ Figure 4 The image collection component in the embodiment collects images, the collected images can cover all parking spaces in the parking lot, and the images can completely include the images of the parking spaces occupied by the parked vehicles and the idle ones with identifiable Marked parking space image.
[0057] In a preferred embodiment, the image acquisition component fixes, rotates or translates to capture images of the berth area, and in the recognition process, we preferably stitch the image acquisition component fixed, rotate or translate to capture the images of the berth area Together to form a panoramic image.
[0058] Step 3: Search and identify the above-mentioned identifiable mark in the digital image;
[0059] We use processing components (for example, a computer with recognition function software) to search and identify, and finally identify the image of the parking space occupied by the parked vehicle and the image of the idle parking space with recognizable marks. We analyze the panorama The presence of the identifiable mark on the parking lot determines and outputs the status and location information of each parking space. For example, through the identifiable mark that indicates the specific location information of the parking lot, the position status information of the free parking space is finally determined. For example, as described in step four:
[0060] Step 4: When the identifiable mark in the corresponding parking space is detected from the digital image, the parking space is considered free; otherwise, the parking space is considered occupied; and,
[0061] Step 5: Output parking space information of the aforementioned free parking spaces.
[0062] The present invention is mainly based on computer image processing technology and uses the image analysis of the overall image to realize the recognition function of the free parking space. Moreover, due to the visibility of the image, the parking space detection system based on identifiable marks of the present invention can be used in addition to In addition to detecting parking berths, it can also provide functions such as video real-time monitoring and historical video query. Moreover, because the present invention only needs to set up cameras, it avoids the need to set up instruments on each berth and will not cause damage to the ground. Destroy, has good economy and space mobility, can be applied to indoor and outdoor parking lots.
[0063] The above-mentioned specific description further elaborates the purpose, technical solutions and beneficial effects of the invention. It should be understood that the above are only specific embodiments of the invention and are not intended to limit the protection of the invention. Scope, any modification, equivalent replacement, improvement, etc., made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
