Webcam as light sensor

3 posts in this topic

Hello.

I need to use a normal USB webcam as light sensor using Autoit.

All I need is to get some "light" number, that depends on the light from the cam. For example - if its a day, the number will be 70 of 100. If its night, the number will be 10 of 100.

I know this is complicated, but if someone know how can it be done, I will be very happy.

Thank you in advance.

Just add up al the pixel colour values in a certain region and divide by the number of pixels. Try the same thing in what you want to consider as dark and what you want to consider as light and take the average. Then anything above that value is light and anything below is dark.

Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.
