This blog shows the Vehicle Situational Awareness System installed on a vehicle and operating both at night and in the daytime.
This picture shows the extra LED illumination panel plus the reversing-view video camera (to the left) and the ultrasonic distance sensor (to the right) all mounted on the rear bumper. It is just possible to see the rear view LCD display mounted on the dash. The other object (in the passenger seat) is a tripod, where the blog recording camera will be mounted.
Note - If you are going to be experimenting with prototype equipment on a car like this, it pays off to use a car that is already painted "duct tape gray", although "duct tape black" might be and even better option. The LED panel is actually quite flexible and could easily be bent to conform to the bumper contour, if a more permanent installation is to be designed.
This video shows operation in the daytime:
For these demonstrations the video camera is angled a bit high just to get more interesting objects in the video.
I found taking video of a low-cost LCD is a difficult challenge both in daylight and at night, especially at an angle.
Here is a demonstration of nighttime operation:
The video guidelines generated by the camera give some indication of distance, but the ultrasonic sensor provides much more definitive distance measurements.
This concludes my Vehicle Situational Awareness System blogs, unless questions arise that I can answer.
I think my next blog will be on reflow soldering of high power Würth LEDs.
