Abstract
公开了一种图像检测方法、图像检测装置、图像检测设备及介质，图像检测方法包括：确定输入图像中一个或多个边缘点及其梯度方向；生成与输入图像具有相同尺寸的初始矩阵，对于初始矩阵中的所有矩阵元素赋予相同的初始值；对每一个边缘点，对位于所述边缘点的累加区域中每一个像素点，在初始矩阵中对该像素点对应的矩阵元素赋予相应累加值，得到累加矩阵；基于累加矩阵确定输入图像中一个或多个圆心的位置；其中，对每一个边缘点，所述边缘点的累加区域包括沿所述边缘点梯度方向的第一累加方向线和与其梯度方向相反的第二累加方向线。通过基于边缘点的梯度方向及与其梯度方向相反的方向共同确定累加区域，提高了图像检测的精确度。
