I run the code.
IDE: 1.6.0; firmware: 2.4.1;
# Hello World Example # # Welcome to the OpenMV IDE! Click on the green run arrow button below to run the script! import sensor, image, time from pyb import UART uart = UART(3, 115200) sensor.reset() # Reset and initialize the sensor. sensor.set_pixformat(sensor.RGB565) # Set pixel format to RGB565 (or GRAYSCALE) sensor.set_framesize(sensor.QVGA) # Set frame size to QVGA (320x240) sensor.skip_frames(time = 2000) # Wait for settings take effect. clock = time.clock() # Create a clock object to track the FPS. while(True): clock.tick() # Update the FPS clock. img = sensor.snapshot() # Take a picture and return the image. uart.write(str(clock.fps())+"\n") # Note: OpenMV Cam runs about half as fast when connected # to the IDE. The FPS should increase once disconnected.
And when I run this code on OpenMV IDE, this fps is 46, when I disabled framebuffer, the fps is 91.
But when I save this code as “main.py” in file system. After boot, the fps is only 29.
So how to improve the fps?
