The invention relates to a method for monitoring illegal parking of an ancient canal watercourse water vehicle. The method comprises the following steps: acquiring a current video frame image; cuttingthe current video frame image according to a monitoring area, and inputting the current video frame image into a water vehicle detection model; judging whether the water vehicle is detected or not, if the water vehicle is not detected, returning to the step 2, and if the water vehicle is detected, executing the step 5; judging whether the ratio of the area of the intersection region to the area of the illegal parking region is greater than an early warning threshold, if the ratio of the area of the intersection region to the area of the illegal parking region is greater than the early warningthreshold, executing step 7, and otherwise, executing step 1; judging whether illegal parking of the water vehicle is detected in the previous frame or not, if illegal parking of the water vehicle isdetected in the previous frame, executing the step 9, and otherwise, executing the step 8; setting that illegal parking of the water vehicle is monitored to be true in the previous frame , and executing the step 2; if the illegal parking condition of the water vehicle exists, reporting an alarm; and judging whether to stop detection, if detection is stopped, stopping detection, otherwise, executing the step 1. According to the method, two times of judgment are used, and the false alarm rate is reduced.
本发明涉及一种监测古运河河道水上交通工具违规停靠的方法,包括如下步骤:获取当前视频帧图像;将当前视频帧图像根据监测区域进行裁切,输入到水上交通工具检测模型中;判断是否检测到水上交通工具,若否则返回步骤2,若是则执行步骤5;判断相交区域面积与违规停靠区域的面积之比是否大于预警阈值,若是则执行步骤7,否则执行步骤1;判断上一帧是否已经检测到水上交通工具违法停靠,若是执行步骤9,否则执行步骤8;设置上一帧已经监测到水上交通工具违法停靠为真,执行步骤2;存在水上交通工具违法停靠情况,进行上报警告;判断是否停止检测,若是则停止检测,否则执行步骤1。本方法使用两次判断,降低了误报率。
