[0085] image 3 A flow chart of the object measurement method provided in this embodiment, the object measurement method includes:

[0086] S301. Obtain a distance parameter between the object to be measured and the shooting terminal.

[0087] In this embodiment, the distance parameter refers to the vertical distance between the front surface of the object to be measured and the plane where the camera of the shooting terminal is located, such as Figure 12 As shown, the surface of the object to be measured includes at least three points A, B, and C, and the distance parameters from these three points to the shooting terminal are D1, D2, and D3 respectively.

[0088] In this embodiment, this step can be implemented in a variety of ways, and the distance can be determined according to user input. For example, the user knows the distance between the object to be measured and the shooting terminal in advance, and can directly input it; Sensors are used to measure the distance in...

Abstract

The present invention provides an object measuring method, a photographing terminal and a computer-readable storage medium. The photographing terminal automatically obtains a distance parameter between an object to be measured and the photographing terminal, a preview size parameter of the object to be measured in a preview screen of the photographing terminal and a focus parameter corresponding to the preview screen, and the actual size parameter measurement of the object to be measured can be determined according to the focus parameter, the distance parameter and the preview size parameter.In the process, a user just needs to use the photographing terminal to face the object to be measured, the operation is simple, the calculation speed is fast, and a problem of complicated operation ofan object measuring method in the prior art is solved. The present invention also provides the photographing terminal and the computer-readable storage medium. By implementing the above scheme, a user experience is enhanced.

Description

technical field [0001] The invention relates to the field of augmented reality, and more specifically, relates to an object measurement method, a shooting terminal and a computer-readable storage medium. Background technique [0002] Users are often faced with the scene of measuring the size of an object. In the prior art, in order to realize the measurement of the size of an object, the following two methods are usually adopted: [0003] One is a measurement method based on the Pythagorean theorem. This measurement method needs to obtain the angle between the light and the object and the size of the object's shadow, and then calculate the object size based on the shadow size and the angle. The angle may change at any time. This method calculates complicated process; [0004] The other is the measurement based on the proportional formula. This method needs to set a target object under the same illumination angle, according to the ratio of the size of the target object to th...
