4. TypeError:'displacement' object is not iterable
  • 免费好用的星瞳AI云服务上线！简单标注，云端训练，支持OpenMV H7和OpenMV H7 Plus。可以替代edge impulse。 https://forum.singtown.com/topic/9519
  • 我们只解决官方正版的OpenMV的问题（STM32），其他的分支有很多兼容问题，我们无法解决。
  • 如果有产品硬件故障问题，比如无法开机，论坛很难解决。可以直接找售后维修。
  • 发帖子之前，请确认看过所有的视频教程，https://singtown.com/learn/ 和所有的上手教程http://book.openmv.cc/
  • 每一个新的提问，单独发一个新帖子
  • 帖子需要目的，你要做什么？
  • 如果涉及代码，需要报错提示与全部代码文本，请注意不要贴代码图片
  • 必看：玩转星瞳论坛了解一下图片上传，代码格式等问题。

      # Optical Flow Example
#
# Your OpenMV Cam can use optical flow to determine the displacement between
# two images. This allows your OpenMV Cam to track movement like how your laser
# mouse tracks movement. By tacking the difference between successive images
# you can determine instaneous displacement with your OpenMV Cam too!

import sensor, image, time

sensor.reset() # Initialize the camera sensor.
sensor.set_pixformat(sensor.GRAYSCALE) # or sensor.GRAYSCALE
sensor.set_framesize(sensor.B64x32) # or B40x30 or B64x64
clock = time.clock() # Tracks FPS.

# NOTE: The find_displacement function works by taking the 2D FFTs of the old
# and new images and compares them using phase correlation. Your OpenMV Cam
# only has enough memory to work on two 64x64 FFTs (or 128x32, 32x128, or etc).
old = sensor.snapshot()

while(True):
    clock.tick() # Track elapsed milliseconds between snapshots().
    img = sensor.snapshot() # Take a picture and return the image.

    [delta_x, delta_y, response] = old.find_displacement(img)

    old = img.copy()

    print("%0.1f X\t%0.1f Y\t%0.2f QoR\t%0.2f FPS" % \
        (delta_x, delta_y, response, clock.fps()))
