The invention relates to a distance measuring method and a device of a smartphone integrated with a depth camera, comprising the following steps: S100: acquiring an RGB map and a depth map of an object to be ranged; S200, displaying the RGB map on the screen of the smart phone, and determining a start point and an end point on the RGB map; S300: searching matching corresponding points in the depthmap for the starting point and the ending point on the RGB map by using the specific correspondence between the points in the RGB map and the depth map; S400: calculating the coordinate value of thecorresponding point in the camera coordinate system of the depth camera, and further calculating the distance from the start point to the end point. The method has the advantages of simple operation,strong flexibility, high precision and small measurement error. 本公开涉及种集成深度相机的智能手机的距离测量方法及装置，包括：S100：获取待测距物体的RGB图和深度图；S200：在该智能手机屏幕上显示该RGB图，在该RGB图上确定起点和终点；S300：利用RGB图和深度图中点的特定对应关系，对于所述RGB图上的起点和终点，在所述深度图中寻找匹配的对应点；S400：计算所述对应点在深度摄
