- for interpreting USB webcam
- for calling OpenAPLR library and returning license plate possibilites + confidence (percentage value)
- Upon movement detected by PIR Motion sensor, script takes a picture by calling Bash script
- Picture is passed OpenALPR Bash script, with entire terminal result kept
- first license plate (most confident guess) is truncated -- try/catch exception block used to analyze case where no license plate was detected
- A HTTP POST request is sent to ParkIT server with following features: license (plate number), time (date of photo), and action (for our demo purposes since only one camera was in use, this was hard set to leaving -- usually will be based on which camera recorded plate)
- Raspberry Pi does not have a X86, AMD64 or X86_64 processor so OpenALPR had to be built from it's source code to fit the Raspberry Pi architechture, compiling all indiviual dependencies
- Optimize the application: with the usage of two bash scripts being called, there is some lag in analyzing pictures. This can be done through: -using Cloud Api for OpenALPR - fixing Python bindings for OpenALPR library
