Hello, I would like to use a light sensor in Isaac Sim. Does this currently exist? Or is there a way to use a camera to detect the amount of light?
Hi @olittlej - Currently, Isaac Sim does not have a dedicated light sensor component. To answer the camera part, I have forwarded question to the right dev.
Hi there,
you could use the camera data to calculate the luminance, where the luminosity formula is:
Y= 0.2126 × R + 0.7152 × G + 0.0722 × B
Here is a simple pseudo code script as an example:
total_lumincance = 0
for pixel in rgb_img:
R, G, B = pixel
luminance = 0.2126 * R + 0.7152 * G + 0.0722 * B
total_luminance += luminance
average_luminance = total_luminance / num_pixels
You can also convert the RGB values to HSV (Hue, Saturation, Value
) and then take the average Value
(brightness) across the image.
