Description

VR lens installation calibration processing method and processing system on VR all-in-one machine

Technical Field

The invention belongs to the field of lens processing of VR (virtual reality) integrated machines, and particularly relates to a processing method and a processing system for VR lens mounting and calibration on a VR integrated machine.

Background

The installation main frame is mainly arranged in front of a display screen of the shell of the host machine, and is provided with lenses.

Further research shows that for a wide-angle lens, the horizontal installation distance between the left lens and the right lens cannot be too far away, and also cannot be too close, so that the horizontal installation distance at the centers of the two lenses should be within a reasonable range (the reasonable range is the standard visual angle installation distance); however, a mounting hole of a long strip waist-shaped hole is designed at present; the mounting hole can be suitable for mounting a left lens and a right lens, but further research finds that in order to adapt to various lens models, a mounting main frame with three or more lengths is often designed; meanwhile, the length of the mounting hole is different, but the identification by naked eyes is easy to make mistakes, and the standard visual angle mounting intervals of each lens are also different; how to quickly determine the installation position for effective automated installation is an urgent problem to be solved by those skilled in the art.

Example one

As shown in fig. 2, a first embodiment of the present invention provides a VR lens mounting and calibrating method for a VR all-in-one machine, including the following steps:

step S101, designing and preprocessing the installation main frame: the mounting main frame 10 comprises a first horizontal mounting frame 11 and a second horizontal mounting frame 12 which is identical to the first horizontal mounting frame and is arranged in parallel; mounting holes 13 with the same length are mounted on the first horizontal mounting frame and the second horizontal mounting frame, and the first horizontal mounting frame is positioned on the inner side of the second horizontal mounting frame; installing a main controller, a first image acquisition module, a first laser generation module, a second laser generation module and a ranging acquisition module on an installation main frame; firstly, preprocessing is executed: the first image acquisition module, the first laser generation module, the second laser generation module and the distance measurement acquisition module are arranged to realize communication connection with a main controller on the VR all-in-one machine;

step S102, the first image acquisition module is installed at the central line position of the installation hole of the first horizontal installation rack, and two lenses (a left lens A and a right lens B) are randomly installed at the installation hole 13 of the second horizontal installation rack 12; meanwhile, the distance measurement acquisition module 60 is arranged in the mounting hole of the second horizontal mounting frame (because the lens on the mounting hole of the second horizontal mounting frame is blocked, the distance measurement acquisition module is not suitable for being arranged in the mounting hole of the first horizontal mounting frame; the specific installation positions are shown in detail in fig. 1;

the image acquisition direction of the first image acquisition module 30 is towards the two lenses for image acquisition, the first image acquisition module 30 identifies the central points of the two lenses, the central points of the two lenses are locked as central point positioning positions, then the first laser generation module is installed at the central point positioning position of the left lens, and the second laser generation module is installed at the central point positioning position of the right lens (the central point positioning position of the left lens can be more accurately acquired by the image acquisition mode of the first image acquisition module, and the technology belongs to the prior art and is not repeated herein by the image processing technology of a gray level histogram mode); the distance measurement acquisition module simultaneously measures the length of the mounting hole on the current first horizontal mounting frame to obtain the real length of the mounting hole; installing a laser reflection identification strip at the current installation hole on the first horizontal installation frame, wherein a laser signal reflector is installed on the laser reflection identification strip;

step S103, in an initial state, randomly determining initial mounting positions of the mounting holes of the left lens and the right lens on the second horizontal mounting rack by a worker (first, performing a judgment processing operation of the initial mounting positions of the mounting holes of the left lens and the right lens on the second horizontal mounting rack);

step S104, aligning a first laser generation module to a current mounting hole on a current first horizontal mounting frame to perform laser ray marking at a first preset angle, and aligning a second laser generation module to the current mounting hole on the current first horizontal mounting frame to perform laser ray marking at the first preset angle (the preset angle is fixed, and the plane of the laser ray at the first preset angle is perpendicular to the horizontal extension direction of the second horizontal mounting frame; namely, the laser generation module emits a vertical ray to the first horizontal mounting frame at the opposite side); the first laser generation module acquires a laser ray returned by a laser reflection identification strip at the current mounting hole on the first horizontal mounting frame, and realizes current ray position marking; then, feedback calculation is carried out to obtain the length ratio of the current mark position of the center of the left lens relative to the real length of the current mounting hole; the second laser generation module obtains a laser reflection identification strip at the current mounting hole on the first horizontal mounting frame and returns laser rays to realize current ray position marking; then, feedback calculation is carried out to obtain the length ratio of the current mark position of the center of the right lens relative to the real length of the current mounting hole;

step S105, the main controller obtains the real length of the current mounting hole, the length ratio of the current marking position of the center of the left lens to the real length of the current mounting hole, and the length ratio of the current marking position of the center of the right lens to the real length of the current mounting hole, and calculates the real distance between the current left lens and the current right lens at the initial position;

step S106, judging whether the real distance at the initial position is within the range of the standard visual angle installation distance of the lens of the model;

As shown in fig. 2, the main controller obtains the actual length of the current mounting hole, the length ratio of the current mark position of the center of the left side lens to the actual length of the current mounting hole, and the length ratio of the current mark position of the center of the right side lens to the actual length of the current mounting hole, and calculates the actual distance between the current left side lens and the current right side lens at the initial position, specifically including the following operation steps:

step S1051, a main controller obtains the real length of the current mounting hole, the length ratio of the current mark position of the center of the left lens relative to the real length of the current mounting hole, and the length ratio of the current mark position of the center of the right lens relative to the real length of the current mounting hole, so as to calculate the relative horizontal position of the current left lens and the current right lens;

step 1052, calculating the real distance between the current left lens and the current right lens at the initial position according to the relative horizontal positions of the two lenses;

step S1053, calculating the gap distance between the left lens at the initial position and the left edge of the mounting hole, and calculating the gap distance between the right lens at the initial position and the right edge of the mounting hole.

It should be noted that, in the technical solution of the present application, according to the actual length of the current mounting hole, the length ratio of the current mark position at the center of the left side lens to the actual length of the current mounting hole, and the length ratio of the current mark position at the center of the right side lens to the actual length of the current mounting hole, the relative horizontal position of the current left side lens and the current right side lens is calculated; certainly, the calculated numerical value of the relative horizontal position of the current left lens and the current right lens is the real distance between the two lenses at the initial position; then calculating the gap distance of the left lens relative to the left edge of the mounting hole at the initial position, and calculating the gap distance of the right lens relative to the right edge of the mounting hole at the initial position; the purpose is to adjust the distance of the left lens or the right lens in order to facilitate the insertion of a mechanical clamping hand into the gap.

As shown in fig. 3, the operation of correcting the left lens and the right lens specifically includes the following steps:

step S1061, a gap distance of the left lens relative to the left edge of the mounting hole at the initial position and a gap distance of the right lens relative to the right edge of the mounting hole at the initial position are taken;

step S1062, determining one of the left lens or the right lens as a target adjusting lens according to the gap distance between the left lens at the initial position and the left edge of the mounting hole, the gap distance between the right lens at the initial position and the right edge of the mounting hole, and the thickness distance of the mechanical clamping hand;

step S1063, the operator starts the mechanical gripper to perform real-time random adjustment of horizontal displacement of the target adjustment lens on the second horizontal mounting frame, and performs subsequent processing operations to determine whether the installation distance range meets the standard viewing angle in real time by using the current random adjustment position and the initial position of the other unadjusted lens as the initial positions of the two lenses (which is equivalent to returning to step S104 to perform the subsequent operations).

It should be noted that, in the technical solution of the present application, the random processing operation is still adopted to facilitate the inspection, and the execution is more convenient and faster. If the reasonable target position of the target adjusting lens is calculated continuously in a calculation mode, the mechanical clamping hand can not accurately move to the reasonable target position, so that the method and the device adopt a real-time mode to judge and process, move and correct, verify and detect at the same time, and are better in efficiency and accuracy.

As shown in fig. 4, the subsequent determination processing operation of determining whether the installation distance range meets the standard viewing angle is executed by taking the current randomly adjusted position and the initial position of the other unadjusted lens as the initial positions of the two lenses in real time, which specifically includes the following operation steps:

step S1064, moving the target adjusting lens by the mechanical clamping hand in a preset horizontal moving direction; taking the current random adjusting position of the target adjusting lens and the initial position of the other unadjusted lens as the initial positions of the two lenses in real time; the first laser generation module is used for aligning the current mounting hole on the current first horizontal mounting frame in real time to carry out laser ray marking at a first preset angle, and the second laser generation module is used for aligning the current mounting hole on the current first horizontal mounting frame in real time to carry out laser ray marking at the first preset angle; the first laser generation module acquires a laser reflection identification strip at a current mounting hole on the first horizontal mounting frame in real time to return laser rays, so that current ray position marking is realized; then, feedback calculation is carried out to obtain the length ratio of the current mark position of the center of the left lens relative to the real length of the current mounting hole; the second laser generation module acquires the laser ray returned by the laser reflection identification strip at the current mounting hole on the first horizontal mounting frame in real time to realize the marking of the current ray position; then, feedback calculation is carried out to obtain the length ratio of the current mark position of the center of the right lens relative to the real length of the current mounting hole;

step S1065, the main controller acquires the real length of the current mounting hole, the length ratio of the current marking position of the center of the left lens to the real length of the current mounting hole and the length ratio of the current marking position of the center of the right lens to the real length of the current mounting hole in real time to calculate the real distance between the current left lens and the current right lens at the initial position;

step S1066, judging whether the real distance at the initial position is within the range of the standard visual angle installation distance of the lens of the model;

if not, the target adjustment lens is continuously moved in the preset horizontal moving direction, and the process returns to step S1064 for iteration.

It should be noted that, in the technical solution of the present application, the mechanical gripper moves the target to adjust the lens in the preset horizontal movement direction; taking the current random adjusting position of the target adjusting lens and the initial position of the other unadjusted lens as the initial positions of the two lenses in real time; from this, the two initial positions are then determined again, from which the iterative processing calculation is carried out again.

During specific calculation, laser ray marking is carried out again, the real length of the current mounting hole, the length ratio of the current marking position of the center of the left lens to the real length of the current mounting hole and the length ratio of the current marking position of the center of the right lens to the real length of the current mounting hole are obtained again, and the real distance between the current left lens and the current right lens at the initial position is calculated; judging whether the real distance at the initial position is within the range of the standard visual angle installation distance of the lens of the model;

if the judgment result is yes, determining that the current initial position is the target installation position of the left lens and the right lens, and stopping the operation of the mechanical clamping hand; meanwhile, if the result of the determination is no, the target adjustment lens is continuously moved in the preset horizontal moving direction, and the step S1064 is repeated.

As shown in fig. 5, the determining of one of the left lens and the right lens as a target adjustment lens according to the gap distance between the left lens and the left edge of the mounting hole at the initial position, the gap distance between the right lens and the right edge of the mounting hole at the initial position, and the thickness distance of the mechanical gripper specifically includes the following operation steps:

step S10621, judging the relation between the gap distance of the left lens relative to the left edge of the mounting hole at the initial position, the gap distance of the right lens relative to the right edge of the mounting hole at the initial position and the thickness distance of the mechanical clamping hand respectively;

step S10622, if the gap distance of only one lens is judged to be greater than the thickness distance of the mechanical clamping hand, determining that the current lens is the target adjusting lens; if the clearance distance between the two lenses is judged to be larger than the thickness distance of the mechanical clamping hand, the current lens with larger clearance distance is determined as a target adjusting lens; and if the clearance distance between the two lenses is judged to be smaller than the thickness distance of the mechanical clamping hand, manually adjusting the target to adjust the lenses.

It should be noted that, in the technical solution of the present application, a relationship between a gap distance between the left lens at the initial position and the left edge of the mounting hole, and a relationship between a gap distance between the right lens at the initial position and the right edge of the mounting hole and a thickness distance of the mechanical clamping hand are determined; reference factors of convenient movement and larger movement space need to be considered, so that if the gap distance of the two lenses is judged to be larger than the thickness distance of the mechanical clamping hand, the current lens with the larger gap distance is determined as a target adjusting lens;

and in a severe case, if the gap distance between the two lenses is judged to be smaller than the thickness distance of the mechanical clamping hand, manually adjusting the target adjusting lens is executed.
