主要函数利用autojs提供的 findCircles函数
images.findCircles(gray, options)
gray {Image} 灰度图片
options {Object} 选项包括:
region {Array} 找圆区域。是一个两个或四个元素的数组。(region[0], region[1])表示找圆区域的左上角;region[2]*region[3]表示找圆区域的宽高。如果只有region只有两个元素,则找圆区域为(region[0], region[1])到图片右下角。如果不指定region选项,则找圆区域为整张图片。
dp {number} dp是累加面与原始图像相比的分辨率的反比参数,dp=2时累计面分辨率是元素图像的一半,宽高都缩减为原来的一半,dp=1时,两者相同。默认为1。
minDst {number} minDist定义了两个圆心之间的最小距离。默认为图片高度的八分之一。
param1 {number} param1是Canny边缘检测的高阈值,低阈值被自动置为高阈值的一半。默认为100,范围为0-255。
param2 {number} param2是累加平面对是否是圆的判定阈值,默认为100。
minRadius {number} 定义了检测到的圆的半径的最小值,默认为0。
maxRadius {number} 定义了检测到的圆的半径的最大值,0为不限制最大值,默认为0。
return {Array}
在图片中寻找圆(做霍夫圆变换)。找到时返回找到的所有圆{x,y,radius}的数组,找不到时返回null。
一个寻找圆的例子:文章来源:https://www.toymoban.com/news/detail-719863.html
// 请求截图
requestScreenCapture();
// 截图
let img = captureScreen();
// 灰度化图片
let gray = images.grayscale(img);
// 找圆
let arr = findCircles(gray, {
dp: 1,
minDst: 80,
param1: 100,
param2: 100,
minRadius: 50,
maxRadius: 80,
});
// 回收图片
gray.recycle();
