Double-indirect-point distance measurement apparatus and double-indirect-point distance measurement method

Abstract

The invention provides a double-indirect-point distance measurement apparatus and a double-indirect-point distance measurement method. According to the present invention, with the apparatus and the method, the long-distance non-contact measurement can be performed on floor slab bottom burying members and other targets, and the projecting point distance of two points positioned at different horizontal planes can be measured, such that the workload for measuring the data by the field worker can be substantially reduced, and the problems in the prior art can be basically solved; and according tothe apparatus, a laser distance measurement device 1 and a laser distance measurement device 2 are arranged to form a V shape, and are rotatably connected at the tail portions through a rotation shaftso as to make the laser distance measurement device 1 and the laser distance measurement device 2 rotate within an included angle of 0-180 DEG, the head portion of the laser distance measurement device 1 is provided with a laser emitting port 1, the head portion of the laser distance measurement device 2 is provided with a laser emitting port 2, an angle sensor is matched with the laser distancemeasurement device 1 and the laser distance measurement device 2 , and a processing module is connected to the laser distance measurement device 1, the laser distance measurement device 2 and the angle sensor.

Description

technical field [0001] The invention relates to a double indirect point distance measuring device and a measuring method thereof, which are mainly used in the field of construction engineering. Background technique [0002] At the project site, a tape measure is usually used to measure the distance between two points, but in some cases, such as when positioning the embedded parts at the bottom of the floor, the two points to be measured are difficult to be directly touched by humans, and can only be reached by scaffolding after reaching a suitable height Manual measurement is complicated and dangerous; and when measuring the distance from the embedded part at the bottom of the beam to the embedded part at the bottom of the floor, since the two points measured are not on the same water level, the distance can only be measured with a tape measure, but The distance marked on the blueprint is generally the projection distance of two points on the same horizontal plane, which mak...

[0002] At the project site, a tape measure is usually used to measure the distance between two points, but in some cases, such as when positioning the embedded parts at the bottom of the floor, the two points to be measured are difficult to be directly touched by humans, and can only be reached by scaffolding after reaching a suitable height Manual measurement is complicated and dangerous; and when measuring the distance from the embedded part at the bottom of the beam to the embedded part at the bottom of the floor, since the two points measured are not on the same water level, the distance can only be measured with a tape measure, but The distance marked on the blueprint is generally the projection distance of two points on the same horizontal plane, which makes it difficult to locate such embedded parts on the project site and affects the progress of the project

[0003] At present, there are also some inventions about non-contact size measurement, such as the patent No. 201210521497.2 "A method and device for optical measurement of the size of dangerous target sources" invention patent, and the invention patent No. 201320135791.X "Portable non-contact size measuring instrument" Patents, both of which use high-resolution CCDs to collect images of target objects, and use image processing algorithms to calculate target size data. large measurement error
