Problems solved by technology

Theodolites that can automatically control the rotation and readings with a computer are rare and very expensive
[0005]Aiming at the requirement of testing the longitude and latitude data of a large number of spatial screen points in geometric correction in multi-channel projection view, we designed a three-dimensional Space longitude and latitude measurement equipment, due to the existence of error phenomena such as axis instability during the rotation process of the general pan / tilt, at the same time we proposed a three-dimensional space longitude and latitude measurement precision algorithm

Embodiment Construction

[0059] A non-customized two-degree-of-freedom pan / tilt and a laser pointer are used to provide a computer-automatically controlled three-dimensional space latitude and longitude measurement system. In terms of specific implementation, the patent of the present invention takes the dual-degree-of-freedom pan / tilt HJY-YT205L as an example to describe in detail the implementation of the hardware system and software algorithm in the patent. For the selection of other pan / tilts, the number of pointers in the laser pointer system should be adjusted according to the specific parameters.

[0060] (1) The physical equipment of the three-dimensional space latitude and longitude measurement system. The design and position installation of the laser pointer system should ensure that the equivalent straight line of the laser beam of each laser pointer passes through the axis of the pan / tilt rotation axis, and on the same plane, the angles between the laser beams of adjacent laser pointers ar...

Abstract

The invention discloses a general holder computer based measuring device with controllable longitude and latitude and a precision method thereof. The device consists of a computer, laser indicators, and the like. A plurality of laser indicators are arranged on a double freedom degree holder; the laser beam equivalent straight lines of the laser indicators pass through the center of a holder rotation shaft and are on the same plane; the laser beams of the adjacent laser indicators have evenly distributed angles in the latitudinal direction; and the double freedom degree holder is arranged on an adjustable horizontal platform. The precision measuring method for the longitude and latitude of a three-dimensional space mainly comprises initial calibration and precision calibration, overcomes the hardware systematic errors and improves the measuring precision.

Description

technical field [0001] The present invention relates to longitude and latitude measurement equipment and software algorithms in large-scale multi-channel projection display systems, in particular to three-dimensional space longitude and latitude measurement equipment controlled by computers and its precision chemical measurement method. Background technique [0002] Demand for ultra-large, high-resolution displays continues to rise in areas such as business, entertainment, and scientific research. It is currently the most feasible technical solution to use multiple projectors to establish a visually seamless super-large field of view high-resolution display system. In order to truly reproduce the three-dimensional field of view environment, a projector is usually used in a large-scale virtual reality display system environment to perform projection imaging on a 360-degree cylindrical display wall or an imaging environment with a closed dome. This kind of display system can...
