A method and apparatus for measuring a distance to an object, by a device (100) having at least two cameras (104, 106), is described. One or more first images including the object are acquired by a first camera of the device and one or more first reference images are acquired by a second camera of the device, while the device is in a first position. One or more second images including the object and one or more second reference images are acquired by cameras of the device, while the device is in a second position, different from the first position. Based on the first and second reference images, information on the displacement of at least one camera of the device between the first and second positions are determined. The distance from the device to the object is calculated based on the first and second images including the object and the determined information on the displacement of the at least one camera. 描述了一种由具有至少两个相机(104，106)的设备(100)测量到对象的距离的方法和装置。在所述设备处于第一位置时，由所述设备的第一相机获取包括所述对象的一个或多个第一图像，并且由所述设备的第二相机获取一
