Hello, I'm currently working on a project with a VL53L8X sensor.
When I installed this product on the ceiling, the data of adults passing by is well observed, but the data of children passing by is not. I understand that this is a physical limitation that comes from the 8by8 array.
Is there a software solution to this?
Thank you
With the sensor mounted on the ceiling it only has to see 2 or 3 feet (60-90cm) to see an adult, but children are a lot shorter and smaller, both of which are leading to your issue. They move faster too.
The trick is to turn up the integration time. Allow the sensor to gather more photons. If you are already running in continuous mode, we are going to have to try running at 12 frames per second instead of 15. Or even 10 frames.
When facing someone straight on, people are pretty big. But when looking down on them they are kind of small. And hair is not very reflective.
Allowing more time will gather more photons.
Another trick is to infer someone is there by not seeing the floor. But if you have a carpet from most of 3 meters away, you might not see the floor - depending on the type of carpet. If you put a wool carpet under the sensor - you could see it easily, but the plastic blends are much harder.
Avoid putting the sensor where sunlight can become a factor. The excess ambient light only makes your problem more difficult.
