How do I need to install/setup the BLIP board for running the Video Occupancy Sensor algorithm to obtain the best detection results?
The BLIP board has 2 on board sensors - The OVM7692 and ASX340AT sensors. For best results the use of ASX340AT is recommended. Choose any of the two on board sensors and install it such that the correct sensor faces the scene. The sensor must be aligned to the field of view (FOV). The imaging sensor must be facing at an angle towards the field of view (perspective installation) or directly facing downwards at zero degree angle (direct overhead installation).
For an perspective installation, the BLIP board must be mounted at a height of 25-40 ft to get a FOV (Field of View) of at least 90 degrees. With such a FOV, the sensor can cover a FOV of 20-30 ft diameter of the scene being monitored.
The FOV of the installation for our testing is shown below:
