The invention discloses a visual positioning method and device, equipment and a storage medium. The visual positioning method comprises the steps that image information of a current area of a vehicle is acquired; extracting point feature information in the image information, and judging an image feature type of the region based on the point feature information; and if the image feature type is a low texture feature, extracting line feature information in the image information, and determining position information of the vehicle based on the point feature information, the line feature information and a preset error loss function. The invention belongs to the technical field of vehicle positioning, and in a low-texture feature region, the line feature information in the image information is extracted to improve the matching precision between the images, so that the positioning accuracy and stability of a visual algorithm in a low-texture scene are improved. 本申请公开了一种视觉定位方法、装置、设备及存储介质，所述视觉定位方法包括：获取车辆当前区域的图像信息；提取所
