Mobile distance measuring device and distance measuring method thereof, and land area measuring method

Abstract

The invention discloses a mobile distance measuring device and a distance measuring method thereof, and a land area measuring method. The mobile distance measuring device includes a mobile carrier, adual-camera shooting distance measuring module, a curved optical disc angle reading module, an included angle measuring module and a processing module. By means of dual-camera image distance measuringand the curved optical disc angle reading module, the resolution per angle is increased, and the distance measuring accuracy can be greatly improved. The invention also discloses an image profile comparison technology which can employ image processing to achieve the aim of automatic image distance measuring, and the problem that an existing ultrasonic distance measuring method or an existing optical distance measuring method or the like can be disturbed easily is solved.

Description

technical field [0001] The invention is a portable and easy-to-carry mobile distance measuring device, which has a dual-lens lens and a curved-surface optical disc angle reading module with a concept of a curved-surface optical disc. Background technique [0002] The existing optical range finder on the market emits a detection beam to the object to be measured, and judges the distance through the structure change of the projected light and reflected light, but the detection light is easily affected by unnecessary light. interference, resulting in erroneous distance measurements. However, the ultrasonic distance measuring method is to transmit an ultrasonic signal to an object to be measured by a measuring terminal, and then calculate the distance of the object to be measured through the reflection time of the ultrasonic signal, but the reflected sound wave of this method is easily affected by obstacles. However, it is interfered, making it impossible to obtain the distance...

AI Technical Summary

Problems solved by technology

Based on this principle, the device can only measure the distance within 20 times of the fuselage, which is quite inconvenient to use, and it is difficult to reduce the size of the overall device

[0004] It can be seen from this that the reliability of the measurement results is based on the precision of the angle. The industry has already complicated, expensive and bulky indexing instruments, which can divide 1 degree into 3600 seconds (that is, the precision can reach 0.00027 degrees), but The instrument is not mobile and portable due to volume and weight issues, which limits its application field
