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.
Code: Select all
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)
Thanks for help,
PS: i did not success to include print instruction in code ?
