一、目标
1、绘制雷达PPI显示器 2、添加雷达扫描线及辉亮，如下图所示。 1、使用OpenCV绘制同心圆和线段，添加指向N和距离刻度文字。主要代码如下： # 绘制雷达显示器界面的同心圆 cv.circle( canvas, (350, 350), 100, white, 2) cv.circle( canvas, (350, 350), 200, white, 2) cv.circle( canvas, (350, 350), 300, white, 2) # 绘制十字线 cv.line( canvas, (50, 350), (650, 350), white, 2 ) cv.line( canvas, (350, 50), (350, 650), white, 2 ) start_point = (int(350-300*np.sin(0.25*np.pi)), int(350-300*np.sin(0.25*np.pi))) end_point = (int(350+300*np.sin(0.25*np.pi)), int(350+300*np.sin(0.25*np.pi))) cv.line( canvas, start_point, end_point, white, 1 ) start_point = (int(350-300*np.sin(0.25*np.pi)), int(350+300*np.sin(0.25*np.pi))) end_point = (int(350+300*np.sin(0.25*np.pi)), int(350-300*np.sin(0.25*np.pi))) cv.line( canvas, start_point, end_point, white, 1 ) # 添加正北指向和距离刻度文字 font = cv.FONT_HERSHEY_SIMPLEX cv.putText( canvas, "N", (340, 40), font, 1, (255, 255, 255), 1) cv.pu |
3、添加运动目标轨迹和参数指示【本文地址】
