This DIY parking assistant uses Lidar, an LED matrix and a Raspberry Pi

Maker Medinc has taken a Raspberry Pi, a couple of Tiny Lidar sensors and a 32×32 LED matrix and created a practical parking assistant. The two sensors are attached to the car at the back and side and then wired through the car to a Raspberry Pi. The Pi is then used to process distance readings and display the assistant’s user interface on the LED matrix.

The 32×32 LED display will assist you by showing arrows to move forward, left or right and a count down display with colored corners to indicate how far you still have to drive.

You can see a demo of the system below and read how he did it on Instructables:
