Here is my code where i try to get the three RGB mean values of a roi.
Unfortunately, i have alway the same three RGB mean values opposite to the RGB mean values written on the RGB color space charts under the image in openmv ide.
import sensor, image, time sensor.reset() sensor.set_pixformat(sensor.RGB565) sensor.set_framesize(sensor.VGA) sensor.skip_frames(time=2000) StartX=0 StartY=0 LengthX=640 HeightY=480 img=sensor.snapshot() meanR=0 meanG=0 meanB=0 for i in range(StartX,StartX+LengthX): for j in range(StartY,StartY+HeightY): rgbtup=img.get_pixel(i,j,rgbtuple=True) meanR=meanR+rgbtup meanG=meanG+rgbtup meanB=meanB+rgbtup meanR=meanR/(LengthX*HeightY) meanG=meanG/(LengthX*HeightY) meanB=meanB/(LengthX*HeightY)
I miss something i suppose…
Thanks for help,
PS: i did not success to include print instruction in code ?
