Description

Improved laser range finder

The invention relates to a measuring device, in particular to a laser optical measuring device capable of measuring the distance between two points of an object to be tested.

In daily life, if we need to measure the length of a distance, we will use tools such as iron ruler and plastic ruler; however, each tool has its own place, and where it is not good, when the distance is more than 30 cm, plastic The ruler is not suitable. When the distance is more than 1 meter, the iron ruler is not suitable; therefore, in order to take a longer distance, the former invented the tape measure. As the size of the tape measure changes, the tape measure can measure 5 meters to The distance is not more than 50 meters, but the tape measure still has several inconveniences; when the distance exceeds a certain level, the tape measure must be operated by two people to be able to measure correctly, because the tape measure itself is a material that will curl, and the measurement The middle section may be curled, so two people must work together to ensure that the tape measure is straightened, otherwise it may cause a large error; however, can there be a single operation and a long distance measurement? What about tools?

As shown in Figure 1, in order to measure longer distances and to reduce errors, a single laser range finder (100) has been invented. The single laser range finder (100) has single operation and high precision. The advantage of degree, in the decoration project, it is quite suitable to use this kind of single laser range finder (100), but the process of measurement often has obstacles on the scene, such as beams, tables, refrigerators and other furniture, however, as in the first As shown in Fig. 2, if there is an obstacle blocking in the middle of the laser path (101) of the single laser range finder (100), measurement cannot be performed. In view of this, one is both portable and easy to use, and A product that can measure the distance by obstructing the obstacle becomes the object of the present invention to be improved.

The following is a detailed description of the following embodiments according to the drawings:

As shown in Figure 3, to measure the length (L) of the starting point (A) to the end point (B) on the object (10), it can be perpendicular to any point between the starting point (A) and the ending point (B). Point (C) extends a vertical line (c') perpendicular to the AB line, the end of the vertical line (c') being the measurement point (D), where the starting line (a') is the starting point (A) and The line connecting the measuring point (D), the end line (b') is the line connecting the end point (B) and the measuring point (D), and the starting angle (θ ₁ ) is the starting line (a') and the vertical The angle of the line (c'), the end angle (θ ₂ ) is the angle between the end line (b') and the vertical line (c'); if we can know the length of the starting line (a') and the end line The length of (b'), knowing the starting angle (θ ₁ ) and the ending angle (θ ₂ ), can calculate the length to be tested (L) by the following formula: L = (sin(θ ₁ ) × a' ) + (sin(θ ₂ ) × b').
