OpenMV有进行仿射变换的库么，或者我可以用什么办法添加函数库进去呢

[13123022550]

现在在做巡双线小车，识别双轨道后平行轨道变成八字形，想利用仿射变换处理，请问openMV可以实现么

你需要自己写或者修改算法，然后import导入模块。

这个变换固件里内置了。

# Rotation Correction
#
# This example shows off how to use the rotation_corr() to undo perspective rotations
# in 3 dimensions along with zooming in and out on the image. While this demo rotates
# the image around for fun you can use this feature to fix perspective issues related
# to how your OpenMV Cam is mounted.

import sensor, image, time

# Degrees per frame to rotation by...
X_ROTATION_DEGREE_RATE = 5
Y_ROTATION_DEGREE_RATE = 0.5
Z_ROTATION_DEGREE_RATE = 0
X_OFFSET = 0
Y_OFFSET = 0

ZOOM_AMOUNT = 1 # Lower zooms out - Higher zooms in

sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QVGA)
sensor.skip_frames(time = 2000)
clock = time.clock()

x_rotation_counter = 0
y_rotation_counter = 0
z_rotation_counter = 0

while(True):
    clock.tick()
    img = sensor.snapshot().rotation_corr(x_rotation = 30, \
                                          y_rotation = 0, \
                                          z_rotation = 0, \

    print(clock.fps())
