Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0020] In the embodiment of the present invention, a method for measuring distance with dual cameras is proposed. The method is applied to a mobile device with two cameras, and the viewing angles of the two cameras overlap. When the mobile device measures the distance, it simultaneously acquires images of the target object through its two cameras, and when it receives an input target point on the image captured by one camera, it determines the target point on the image captured by the other camera The position of the imaging point is used to calculate the distance from the target object to the mobile device, and the distance from the mobile device to the target object can be accurately measured.

[0021] The mobile device in the specifi...

Abstract

The application discloses a method for measuring distance of double-camera. The method comprises the following steps: simultaneously obtaining an image of a target object through the two cameras when a mobile apparatus is used for measuring distance, when receiving a target point on an input image obtained by a camera, determining a position of an imaging point of the target point on the image obtained by other camera so as to compute the distance from the target object to the mobile apparatus. Based on the same inventive concept, the application further provides a device for accurately measuring the distance from the mobile apparatus to the target object.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for measuring distance with dual cameras. Background technique [0002] With the popularization and application of mobile devices, mobile devices such as mobile phones have become indispensable in life, and various additional functions of mobile devices have attracted more and more attention. Such as shooting function, ranging function, etc., which increase user experience and fun. [0003] Among various existing mobile devices, some mobile devices can measure the distance to a visible target object through a single camera, but the height of the camera from the ground needs to be known to calculate the distance from the mobile device to the target object. Usually the height of the camera from the ground is not easy to obtain, even if the height of the camera from the ground is obtained, there will be a large error, so that the measured ...
