“…So, in a nutshell, camera-viewing angles, camera resolutions, and the heights at which cameras are situated are critical parameters for efficient real-time parking detection. The prototype model gives the best results in the articles by Trivedi et al (2017Trivedi et al ( , 2020aTrivedi et al ( , 2020b, when the camera is situated at 90 degree angles because it focuses only on specific parking locations with parked vehicles. Here, we assume the camera is situated at a height of 3 meters from the ground surface and at an angle of around 40 to 50 degrees.…”

“…A mono-camera-based parking module is explained by Davarci et al (2018) with the image-processing method, but a real-time parking demonstration is not presented in that study. A prototype model for a smart city parking system is established in Trivedi et al (2017Trivedi et al ( , 2020aTrivedi et al ( , 2020b; however, work for a real-time parking management system is not demonstrated there. A canny edge-detection-based real-time parking management system is explained in Trivedi et al (2020aTrivedi et al ( , 2020b with parking characteristics.…”

Purpose The purpose of this paper is to find a real-time parking location for a four-wheeler. Design/methodology/approach Real-time parking availability using specific infrastructure requires a high cost of installation and maintenance cost, which is not affordable to all urban cities. The authors present statistical block matching algorithm (SBMA) for real-time parking management in small-town cities such as Bhavnagar using an in-built surveillance CCTV system, which is not installed for parking application. In particular, data from a camera situated in a mall was used to detect the parking status of some specific parking places using a region of interest (ROI). The method proposed computes the mean value of the pixels inside the ROI using blocks of different sizes (8 × 10 and 20 × 35), and the values were compared among different frames. When the difference between frames is more significant than a threshold, the process generates “no parking space for that place.” Otherwise, the method yields “parking place available.” Then, this information is used to print a bounding box on the parking places with the color green/red to show the availability of the parking place. Findings The real-time feedback loop (car parking positions) helps the presented model and dynamically refines the parking strategy and parking position to the users. A whole-day experiment/validation is shown in this paper, where the evaluation of the method is performed using pattern recognition metrics for classification: precision, recall and F1 score. Originality/value The authors found real-time parking availability for Himalaya Mall situated in Bhavnagar, Gujarat, for 18th June 2018 video using the SBMA method with accountable computational time for finding parking slots. The limitations of the presented method with future implementation are discussed at the end of this paper.

“…Before detection, the image needs to be preprocessed, such as filtering, image segmentation, morphological processing, edge detection, etc., as shown in Figure 15. For circle detection in images, Hough circle transformation is a circle detection algorithm widely used by relevant scholars [17,18]. However, the standard Hough transform algorithm is complicated and inefficient.…”

This paper introduces the mechanical design and control system of a mobile robot for logistics transportation in manufacturing workshops. The robot is divided into a moving part and a grasping part. The moving part adopts the mecanum wheel four-wheel-drive chassis, which has omnidirectional moving ability. The mechanical system is based on four mechanical wheels, and a modular suspension mechanism is designed. The grasping part is composed of a depth camera, a cooperative manipulator, and an electric claw. Finally, the two are coordinated and controlled by computer. The controller hardware of the mobile platform is designed, and the functional modules of the mobile platform are designed based on the RT thread embedded system. For the navigation part of the mobile robot, a fuzzy PID deviation correction algorithm is designed and simulated. Using the Hough circular transform algorithm, the visual grasping of the manipulator is realized. Finally, the control mode of the computer-controlled manipulator and the manipulator-controlling mobile platform is adopted to realize the feeding function of the mobile robot, and the experimental verification is carried out.
