description A method and a system for detecting a long-distance target through a binocular camera, and an intelligent terminal are provided. The method includes the steps of: acquiring original images generated by the binocular camera at a target region, acquiring a disparity map in accordance with the original images, and converting the disparity map into a space information point cloud map; partitioning a predetermined target detection range into a plurality of sub-ranges in accordance with the space information point cloud map, and acquiring a disparity threshold segmentation image for each sub-range; calculating an integral image in accordance with each disparity threshold segmentation image, and acquiring a heatmap of an obstacle in accordance with the integral images; and reversely mapping a maximum matching region in the heatmap to the original image, so as to acquire a target ROI for the obstacle, thereby to acquire a position of the obstacle.
