Problems solved by technology

[0004] However, in the prior art, the measurement method through the scale ruler is limited by the length of the terminal itself, that is, when the length of the target object is significantly longer than the length of the terminal itself, the length of the target object cannot be measured; and the measurement method by taking pictures, It is easily affected by factors such as the resolution of the terminal camera, the clarity of the photo image, the brightness of the environment, and the angle of the camera when shooting, resulting in a large error in the measurement length; and the length must be taken first, which increases the complexity of the measurement Spend

Embodiment 1

[0056] figure 1 Schematic flow chart of a length measuring method provided for an embodiment of the present invention Figure 1 , the method includes:

[0057] Step 101: When the measurement function of the terminal is turned on and the terminal is at the first position, the terminal starts the beam emission command. The first position is that the first side of the terminal coincides with the first end of the object under test, and the first plane is where the object under test is located. The position of the terminal when the second plane is facing and parallel;

[0058] Wherein, the first side of the terminal includes the side where the side of the terminal is located. Exemplary, see figure 2 As shown, the first side 11 of the terminal is the side where the right side of the terminal is located. It should be noted that, the embodiment of the present invention does not specifically limit the setting of the first side of the terminal.

Abstract

The embodiment of the invention discloses a length measurement method and a terminal. The method comprises: when the measurement function of a terminal is started and the terminal is located at a first position, the terminal starts a light beam emission instruction; the terminal emits a first light beam according to the light beam emission instruction, and the first light beam and a first plane form an emission included angle; when the first light beam is emitted, the terminal obtains first operation, and the first operation is configured to indicate the terminal to rotate taking a first edge as an axis; when the terminal is rotated from the first operation to a second position based on the first operation, the terminal obtains a rotation angle, and the second position is a position of the first edge of the terminal being overlapped with the first end of an object to be measured and the first light beam reaching the second end of the object to be measured; and the terminal calculates the length of the object to be measured according to the preset angle of the emission included angle, a preset distance and the rotation angle, the length of the object to be measured is a distance from the first end to the second end, and the preset distance is a distance from an arrangement point of a light emission unit on the first plane to the first edge.

Description

technical field [0001] The invention relates to the communication field, in particular to a length measurement method and a terminal. Background technique [0002] Currently, with the rapid development of terminals, more and more applications are set on the terminals. For example, the length of objects such as tables, doors, boxes, and televisions can be measured through the terminals. [0003] In the prior art, the terminal directly measures the length of the target object by setting a virtual or physical scale inside itself. Alternatively, the terminal takes a photo of the target object through its own camera and obtains the photo, uses image processing technology and refers to the reference length, processes the photo of the target object, and obtains the length of the target object. [0004] However, in the prior art, the measurement method through the scale ruler is limited by the length of the terminal itself, that is, when the length of the target object is significa...
