This was developed during one day and the algorithm is pretty stupid. Unfortunately the code is lost. However this is how it was done: 1. Perspective transfo.
Parking space is becoming a serious problem due to the day-by-day increase in number of vehicles on the road. In cities with large population, or in places where sports or artistic events are scheduled, we have probably all experienced driving around in circles looking for a parking space. Sometimes, it is very frustrating to find one space.
*Slot, label, and array sensors are specialty sensors designed to solve specific applications. Slot sensors detect objects that pass between the two arms – one with the emitter and the other with the receiver. The fixed slot width provides reliable opposed-mode sensing of objects as small as 0.30 mm.
*To detect parking slots with only one DCNN model, Zinelli et al. (2019) proposed an end-to-end DCNN model based on a faster region-based FIGURE 1 Overview of the parking slot detection method on.
*APPROACH TO DETECT OCCUPANCY The problem can be broken into two parts, detecting where the parking slots are located, and detecting if a slot is occupied. We can manually mark the areas of the parking lots, but this is a cumbersome process, which must be repeated each time we change the camera’s position.
*The parking slot marking detection stage recognizes various types of parking slot markings. The parking slot occupancy classification stage identifies vacancies of detected parking slots using ultrasonic sensor data. Parking slot occupancy is probabilistically calculated by treating each parking slot region as a single cell of the occupancy grid.
In order to combat this problem, few cities have implemented a so-called ’active parking lot management system’, which has the benefits of guiding drivers to open parking spaces, saving time costs associated with parking, efficient parking management, better traffic flow, reduced pollution and energy waste, etc.

Parking occupancy detection
The key to active parking lot management is the reliable detection of available parking spaces. It is achieved by wireless sensor in every parking space, which can detect the presence of a car in the space and note the arrival/exit time of a vehicle. Parking lot statuses (occupied or idle) are detected and transmitted to a clould database. This information then be accessed by users through website or mobile APPs to receive real-time updates.
WiiHey has developed a parking lot sensor that is scarcely bigger than a mug cup in terms of its circumference and measures around about three centimeters in height. The sensors are installed in parking garages or on-street parking spaces. The special thing about this product is that the sensors operate wirelessly and are powered by batteries, which eliminates the effort and expense of having to lay cables.
The working principle of the sensor is an inside magnet-resistive sensor that measures the Earth’s magnetic field. As vehicles come within range of the sensor, changes in the surrounding magnetic field occur and are detected. Each sensor continually monitors the background magnetic field to establish a base reference, allowing self-calibration & self-learning so that it is able to differentiate parking events from other electromagnetic interferences.

Architecture
The parking lot sensor uses narrow band (NB) IoT communications technology, which combines high transmission ranges of up to several kilometres in urban environments, with low power consumption. Data are then transmitted to cloud services across the IoT network for further processing and delivery into the end-user’s system.

WiiHey parking lot sensor is easy to install, low-maintenance in-ground vehicle detection sensors gather information on parking space occupancy statuses. The sensors feed data to cloud which can then be used for a range of third-party parking management systems. The data can be used to enable additional smart parking services such as integrated parking guidance, car locating or cash-less payment to further simplify the parking process.

Automatic car parking indicator system
General application and Description of the project
Nowadays in many multiplex systems there is a severe problem for car parking systems. There are many lanes for car parking, so to park a car one has to look for the all lanes. Moreover there is a lot of men labor involved for this process for which there is lot of investment. So the need is to develop a system which indicates directly which parking slot is vacant in any lane. The project involves a system including infrared transmitter and receiver in every lane and a LED display outside the car parking gate. So the person entering parking area can view the LED display and can decide which lane to enter so as to park the car.
Conventionally, car parking systems does not have any intelligent monitoring system. Parking lots are monitored by human beings. All vehicles enter into the parking and waste time for searching for parking slot. Sometimes it creates blockage. Condition become worse when there are multiple parking lanes and each lane have multiple parking slots. Use of automated system for car parking monitoring will reduce the human efforts. Display unit is installed on entrance of parking lot which will show LEDs for all Parking slot and for all parking lanes. Empty slot is indicated by the respective glowing LED.
Working of the circuit and image of the model Highest blackjack bet ever.
IR Sensors are placed inside the parking slot to detect the presence of the vehicle in slot. If the slot is not vacant then a red led will glow under the specified slot number at the entrance of the parking area or else green led will glow. The Arduino takes the data from the IR sensors and compares the received value with the threshold value and accordingly supplies power to the desired led.

Description of the Circuit
In circuit there are 3 IR sensors are used each at 3 parking slot. These IR sensors are connected to the pin A0, A1, A2 respectively. The led’s are connected at the Digital I/O pins i.e., pin 2 for RED1, pin 3 for GREEN1, pin 4 for RED2, pin 5 for GREEN2, pin6 for RED3 and pin 7 for GREEN3.
When the slot1 will be vacant then IR receiver will not receive any signal. Hence GREEN1 will glow. If any signal is received by the IR receiver then it will be compared to the threshold value and if it is more than the threshold value then RED1 will glow. This process will be similar to all other slots.
