The invention relates to an early warning method for entering of a battery car in an elevator car. The early warning method comprises the following steps that it is set that the battery car monitoredin the last frame is false; a current video frame image is obtained; the current video frame image is inputted into a battery car detection model to obtain attribute information of a target; whether the battery car is detected or not is judged, if not, the step 2 is returned, and if yes, the step 5 is carried out; whether the battery car is detected in the previous frame or not is judged, if so, the step 7 is carried out, and otherwise, the step 6 is carried out; that the battery car monitored in the previous frame is true is set, and the step 2 is carried out; if the battery car enters the elevator car, a warning is reported; and whether to stop detection is judged, if so, detection is stopped, otherwise, the step 1 is carried out. According to the early warning method for entering of thebattery car in the elevator car, multiple targets possibly occurring in the elevator car are detected, two times of judgment are used, and the false alarm rate of targets similar to the battery car such as bicycles is reduced.

    本发明涉及一种升降梯轿厢内电瓶车进入预警方法,包括如下步骤:设置上一帧已经监测到电瓶车为假;获取当前视频帧图像;将当前视频帧图像输入到电瓶车检测模型中,获取目标的属性信息;判断是否检测到电瓶车,若否则返回步骤2,若是则执行步骤5;判断上一帧是否已经检测到电瓶车,若是执行步骤7,否则执行步骤6;设置上一帧已经监测到电瓶车为真,执行步骤2;存在电瓶车进入升降梯轿厢情况,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。本升降梯轿厢内电瓶车进入预警方法,检测多种升降梯轿厢内可能出现的目标,使用两次判断,降低了与电瓶车相似目标如自行车的误报率。
