Vision angle and vision field measurement method for drivers

Abstract

The invention discloses a vision angle and vision field measurement method for drivers, which is characterized in that: a laser tracker (20) and a T-Probe detector (28) are employed for measuring horizontal measurement points (24, 29) on an airplane (23) and other horizontal measurement points on the whole airplane; the horizontal measurement points are employed as basic points to fit a coordinate system of the airplane; under the coordinate system of the airplane, the laser tracker performs setting-out survey, wherein an eye position measurement point (25) on a positioning measurement tool (22) is located at a design eye position; when a driver sits up on a seat (21) with center of two eyes being pressed against the eye position measurement point (25), the driver observes the T-Probes on the characteristic points P1-Pn on a front windshield (27) and an instrument screen (26) and then sends a visual measurement command; and by means of the coordinate of the eye position measurement point (25) and the actual measurement coordinates of the points P1-Pn, a straight line (vision line) is established, and finally the included angles between the vision line and a horizontal structural surface of the airplane and between an axial symmetrical surface and an axial section are calculated, so that vision field can be obtained from a limit vision angle.

Description

technical field [0001] The invention belongs to the technical field of engineering measurement and relates to a method for measuring a driver's angle of view and horizon. Background technique [0002] In the prior art closest to the invention, the measurement process of the driver's angle of view and field of vision is to remove the driver's seat, put a theodolite into the cockpit, and reproduce the rotation center of the theodolite at the driver's design eye position. By rotating the theodolite mirror tube, aim at the front windshield boundary or the side window boundary of the cockpit, and then directly read the horizontal angle and pitch angle through the reading device on the theodolite. [0003] The disadvantage is that the human eye does not actually observe at the designed eye position, but observes through the light pipe of the telescope, which is different from the real human eye observation. This method can only measure the horizontal angle and pitch angle, and do...
