Basic surround-view Parking systems

-


Parking Surround-view systems generally use four to six wide-angle-view cameras mounted on the front, rear and sides of a vehicle. The fish-eye lenses used on these cameras produce a distorted bowl-shaped view that geometric alignment algorithms correct. These corrected images then need balancing and color correction for consistency and final stitching into a single 360-degree view around the car.

An animated model of the car is rendered at the center of the stitched image to give the driver a bird’s eye view of her environment. It is also possible to add other overlays to the image that show the car’s position relative to objects that the cameras see.

A system-on-chip (SoC) for this application requires capacity for multiple camera inputs, an image signal processor and hardware acceleration for image adjustment and tuning, a graphics processing unit for creating the car model, and image overlays and processing cores for algorithmic analysis of the images.

THE GROWING DEMAND IN EUROPE OF PARKING FOR TRUCKS According to a recent report from the European Commission, parking areas for trucks are increasingly needed in Europe. In particular, the study speaks of a deficit of 400,000 parking spaces for trucks and heavy vehicles. Unfortunately the collective is suffering more and more robberies, 75% of which in the parking areas themselves, so the European Union wants to promote parking areas for safe and protected trucks. The current situation is not comfortable for the transport sector, the drivers do not feel safe when they rest and the owners of the cargo are exposed to continuous theft and economic losses. According to the transport organization IRU, the theft losses represented 6,000 to 7,000 million euros last year. THE PROBLEMS OF THE CURRENT TRUCK PARKING ZONES PARKING WITHOUT HOMOLOGAR. Currently truck parking areas are different everywhere, without following a pattern, which causes uncertainty among truck drivers

Parking in front of a gate or driveway

Although this practice is particularly prevalent in large cities,  parking the vehicle in front of a gate or in front of a driveway is an offense. Drivers who might be tempted by the facility risk a 2nd class parking ticket for inconvenient parking. This is motivated by the fact that the position of the vehicle hinders the movement of other users. Moreover, even if it can be tolerated, parking in front of the gate or the driveway of his home is also an offense that can be punished. What are the risks of parking in front of a gate or driveway? Drivers who decide to take the risk of parking in front of a gate or driveway are in violation. Also, in case of control, they will be sanctioned. Indeed, French legislation provides that: "Any stop or parking embarrassing is punishable by the fine provided for the contraventions of the second class. Where the driver or the owner of the vehicle is absent or refuses, in spite of the officers' injunction, to stop the awkward parking

The Future of the $100 Billion Parking Industry

-
From self-driving vehicles to the rate of urbanization to the buzz of the car-sharing economy, it’s easy to surmise the death of parking. Yes, vehicle ownership is down and, yes, as The New York Times reported, the millennial generation values technology over cars. But the death of parking? Not quite. According to a recent analysis by Frost & Sullivan, the $100 billion worldwide parking industry is expected to attract institutional and strategic investments to the tune of $200 million to $250 million over the next three to five years, mostly to spur innovation and smarter parking.  A big reason for this infusion of capital is to remedy the inefficiencies in the ways that we park, per recent findings. So why has the parking industry taken so long to innovate? Until recently, parking and innovation have mixed like water and oil. This is largely due to the slow-changing nature of the two-headed parking industry, which comprises both on-street and off-street parking. On-stre
