Direct reading crude distance measuring system and method based on binocular parallax in virtual reality and augmented reality environments

Abstract

The invention discloses a direct reading crude distance measuring system and method based on binocular parallax in virtual reality and augmented reality environments. The system comprises a control module, a processing module, a resolving module and a display screen module which are sequentially connected, wherein the control module is used for opening or closing control and executes following actions: opening or closing distance measuring functions, changing distance measuring scaleplate unit or proportion and controlling display and hiding of distance measuring graphs, so that the distance measuring graphs get close to or get away from an observer; the processing module is used for processing various operation transmitted by the control module and executing processing; the calculation module is used for calculating data required to be executed and calculating the distance between the graphs and the observer in a distance measuring mode with a contrast method; the display screen module displays all elements required to be displayed. The implementation method is simple and rapid, has low precepted characteristics, does not emit laser and acoustic waves, realizes distance measurement only in an optical mode without additional equipment and excellent in mobility.

Description

technical field [0001] The invention relates to the technical field of distance measurement, in particular to a system and method for direct reading and rough distance measurement based on binocular parallax in virtual reality and augmented reality environments. Background technique [0002] Spatial ranging has always been a relatively common requirement, but generally involves more equipment and relatively heavy weight, which is not suitable for portable use. [0003] At present, the commonly used distance measuring method is the eye jump method. The eye jump method is to raise the thumb and straighten the arm, open one eye in turn to determine the projection position of the thumb, estimate the distance L between the two thumb projections, and multiply the distance L by 10 is the target distance. This method is mostly used in the military field in reality, but the finger cannot be displayed in real time in the current virtual reality, so it is difficult to realize. [000...

AI Technical Summary

Problems solved by technology

[0005] Sound waves and ultrasonic distance measurement are more accurate, but the transmitting and receiving equipment needed to emit sound waves and ultrasonic waves is more complicated, and it is not suitable for carrying around

[0006] The above physical distance measurement methods in reality cannot be used in virtual reality
