这个错误是由于filter2D函数的输入类型不匹配导致的。在这里，您正在使用UMat类型的图像，但是filter2D函数不支持UMat类型的图像。您可以尝试将UMat类型的图像转换为numpy数组类型的图像，然后再进行模糊处理。这里是修改后的代码：

import cv2
import numpy as np
import os

def motion_blur1(image, degree=10, angle=45):
    image = np.array(image)
    # 生成任意角度的运动模糊kernel的矩阵， degree越大，模糊程度越高
    M = cv2.getRotationMatrix2D((degree / 2, degree / 2), angle, 1)
    motion_blur_kernel = np.diag(np.ones(degree))
    motion_blur_kernel = cv2.warpAffine(motion_blur_kernel, M, (degree, degree))
    motion_blur_kernel = motion_blur_kernel / degree
    # 将UMat类型的图像转换为numpy数组类型的图像
    blurred = cv2.filter2D(image.get(), -1, motion_blur_kernel)  
    # convert to uint8
    cv2.normalize(blurred, blurred, 0, 255, cv2.NORM_MINMAX)
    blurred = np.array(blurred, dtype=np.uint8)
    # 将numpy数组类型的图像转换为UMat类型的图像
    blurred = cv2.UMat(blurred)
    return blurred

filePath = r'D:\Users\Administrator\PycharmProjects\pythonProject\paper_need\blur'
for i in os.listdir(filePath):
    outPath = r'D:\Users\Administrator\PycharmProjects\pythonProject\paper_need\blur.' + str(i)
    img = cv2.imread("./deblur/"+i)
    img = cv2.UMat(img)
    img_ = motion_blur1(img)
    cv2.imwrite(outPath,img_.get())

这里将UMat类型的图像转换为numpy数组类型的图像，然后进行模糊处理，最后再将numpy数组类型的图像转换为UMat类型的图像。这样就可以解决这个问题了。
