The invention provides a method and a system for sensing door opening by recognizing a kicking action based on a vehicle-mounted camera. The method comprises the following steps: S1, detecting a current vehicle body signal in real time; s2, when it is detected that the vehicle gear is the P gear and a vehicle door is in a closed state, original image data of a camera are obtained; s3, performing image segmentation and cutting on the original image data of the camera so as to obtain image data of a fixed detection area; s4, converting the image data of the fixed detection area into a grey-scale map; s5, kicking action detection is carried out on the grey-scale map through an optical flow method; s6, when the condition of the kicking action is met, a door opening signal is triggered; and S7, after the single-chip microcomputer receives the trigger signal, the motor is controlled to open an electric door of the vehicle. According to the scheme, on the basis of the vehicle-mounted 360-degree looking-around system, the foot kicking action of a person who wants to open the vehicle door is recognized through the camera, so that a signal is triggered to automatically open the electric vehicle door, and additional cost does not need to be increased.

    本发明提供了一种基于车载摄像头识别脚踢动作感应开门的方法和系统,所述方法包括:步骤S1:实时检测当前车身信号;步骤S2:当检测到车辆档位为P档且车门为关闭状态时,获得摄像头原始图像数据;步骤S3:对摄像头原始图像数据进行图像的分割裁剪,从而获得固定检测区域图像数据;步骤S4:将固定检测区域图像数据转化为灰度图;步骤S5:对灰度图通过光流法进行脚踢动作检测;步骤S6:当满足脚踢动作的条件时,触发开门信号;步骤S7:单片机收到触发信号后,控制电机开启车辆的电动门。本发明首次提出了在车载360环视系统的基础上,通过摄像头识别想要打开车门的人的脚踢动作,从而触发信号自动开启电动车门的方案,无需额外增加成本。
