This paper focuses on implementing Raspberry Pi based “ Automated Parking and Security System”, using different technologies based on the developments in Smart Sensors, Image processing and Raspberry Pi- RPI model with their comparative analysis. The research survey includes the current scenario of the Parking Systems incorporating technologies such as Automatic Number Plate Recognition- ANPR, RPI, Wireless sensor network and Wi-Fi based automatic space booking system. The combination of above solutions is considered for designing and implementing an “Automated Parking and Security System”, going to be considered as “One Time Investment”. The prototype is established on grounds of RPI 3B model, Image Processing - blurring, dilating, eroding, contouring and segmenting of Number Plate and Face Recognition which would resolve the problems faced by existing systems and would satisfy the requirements of an accurate and secured parking system. As a whole, it is a confined user-friendly and easily modifiable for future requirements and applications.
