Portable and simple range finding device

Abstract

The invention belongs to the technical field of range finding apparatuses, and in particular, to a portable and simple range finding device. The portable and simple range finding device comprises an infrared emitter and an infrared receiver, and further comprises a telescopic bracket and a rotary mounting bracket; the telescopic bracket comprises a base, a first vertical sleeve mounted on the base, and a second vertical sleeve sleeved outside the upper end of the first vertical sleeve; the rotary mounting bracket comprises a fixed shaft, a rotating disc, a movable plate, and an angle adjustingdevice for adjusting the angle of the movable plate. According to the invention, the height of the infrared emitter and the height of the infrared receiver are adjusted by means of the telescopic bracket, and the position and angle of the infrared receiver are adjusted by the rotary mounting bracket; thus, the receiving device of the range finding device is simplified, and the data processing works of a image processor and a signal processor are further simplified.

Description

technical field [0001] The invention belongs to the technical field of distance measuring equipment, and in particular relates to a portable simple distance measuring device. Background technique [0002] Ranging is a common operation method such as urban planning, which uses a ranging device to measure the distance of distant obstacles. Common ranging devices include laser rangefinders, infrared rangefinders, laser rulers, etc. Although the specific ranging principles of different ranging devices are different, they basically include transmitters and receivers. The transmitter is used to transmit A test light, the test light is reflected by the object to be tested and received by the receiver, and finally the image processor and the signal processor are used to process the time difference data between emission and reception to calculate the object distance. [0003] Although the selected test light is generally linear, due to the influence of other rays and other frequenci...

AI Technical Summary

Problems solved by technology

However, as the number of infrared emitters increases, the data processing work of the image processor and signal processor also increases, requiring complex signal processing programs, and the increase of infrared emitters also requires a more complex circuit structure.

[0004] Therefore, the technical problem in the prior art is that there is a lack of a distance measuring device that requires less infrared transmitters and infrared receivers and can reduce test blind spots.
