The invention relates to a vehicle tailgate opening and closing control system and method. The system includes a projection lamp configured to project a predetermined pattern to a preset area; a camera configured to capture an image within the preset area; the image recognition module is configured to receive the image captured by the camera and determine whether the foot of the person is included in the received image or not; and the controller is configured to send a control instruction for opening the tail door of the vehicle in response to the fact that the received image comprises the feet of the person. Acquiring an image of a preset area irradiated by the projection lamp through the camera, performing feature extraction on the image to obtain foot feature information, and comparing the foot feature information with foot feature information of each sample image in a preset database; when the similarity value with the foot feature information of at least one sample image in the preset database exceeds the preset threshold value, it is determined that the foot of a person enters the preset area, and the tail gate is triggered to be opened, so that the accuracy of opening the tail gate is improved.

    本发明涉及车辆尾门的开关控制系统和方法。所述系统包括投影灯,其配置为将预定图案投射到预设区域;摄像机,其配置为捕获所述预设区域内的图像;图像识别模块,其配置为接收摄像机捕获的图像,确定接收到的图像中是否包括人的脚部;控制器,其配置为响应于确定出接收到的图像中包括人的脚部,发送使车辆尾门打开的控制指令。通过摄像机获取投影灯照射的预设区域的图像,对图像进行特征提取得到脚部特征信息,将脚部特征信息与预设数据库中各个样本图像的脚部特征信息进行比较,当与预设数据库中的至少一个样本图像的脚部特征信息的相似度值超过预定阀值时,确定出有人的脚部进入预设区域,触发尾门打开,从而提高了尾门打开的准确度。
