Description

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

Technical Field

The installation main frame is mainly arranged in front of the display screen of the host shell, and meanwhile, the installation lens is installed.

Further studies have found that for wide angle lenses, the horizontal mounting distance between the left and right lenses should not be too far, nor too close, so that the horizontal mounting spacing at the center of both lenses should be within a reasonable range (the reasonable range is the standard viewing angle mounting spacing); however, a mounting hole of a strip-shaped waist-shaped hole is designed at present; the mounting hole can be suitable for mounting left and right lenses, but further research finds that in order to adapt to various lens models, three or more lengths of mounting main frames are designed; meanwhile, the lengths of the mounting holes are different, but the visual recognition is easy to make mistakes, and the standard visual angle mounting interval of each lens is also different; how to quickly determine the installation location to achieve efficient automated installation is a matter of urgent need for those skilled in the art.

step S102, the first image acquisition module is arranged at the center line position of the mounting hole of the first horizontal mounting frame, and two lenses (a left lens A and a right lens B) are randomly arranged at the mounting hole 13 on the second horizontal mounting frame 12; meanwhile, the ranging acquisition module 60 is arranged in the mounting hole of the second horizontal mounting frame (the lens on the mounting hole of the second horizontal mounting frame is shielded, so that the ranging acquisition module is not suitable for being mounted in the mounting hole of the first horizontal mounting frame, and the length of the mounting hole on the current first horizontal mounting frame is measured through the ranging acquisition module to obtain the real length of the mounting hole); the specific installation position is shown in fig. 1;

The image acquisition direction of the first image acquisition module 30 is towards two lenses to acquire images, the first image acquisition module 30 recognizes the center points of the two lenses, locks the center points of the two lenses as center point positioning positions, then installs the first laser generation module at the center point positioning position of the left lens, installs the second laser generation module at the center point positioning position of the right lens (the center point positioning position of the left lens can be acquired more accurately by the image acquisition mode of the first image acquisition module, and the technology belongs to the image processing technology of the gray histogram mode, which is not repeated in the prior art); the distance measurement acquisition module is used for simultaneously measuring 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 a 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, the initial installation positions of the installation holes of the left lens and the right lens on the second horizontal installation frame are randomly determined by a worker (firstly, the judgment processing operation of the initial installation positions of the installation holes of the left lens and the right lens on the second horizontal installation frame is executed);

Step S104, the first laser generating module is aligned with the current mounting hole on the current first horizontal mounting frame to perform laser ray marking of a first preset angle, the second laser generating module is aligned with the current mounting hole on the current first horizontal mounting frame to perform laser ray marking of the first preset angle (the preset angle is fixed, the plane of the laser ray of the first preset angle is perpendicular to the horizontal extending direction of the second horizontal mounting frame; namely, the laser generating module emits a ray in the vertical direction to the opposite first horizontal mounting frame); the first laser generation module acquires a laser reflection identification strip returned laser ray at a current mounting hole on the first horizontal mounting frame to realize current ray position marking; then, feedback calculation is carried out to obtain the length ratio of the current marking position of the center of the left lens relative to the actual length of the current mounting hole; the second laser generation module acquires laser reflection identification strips at the current mounting holes on the first horizontal mounting frame to return laser rays, so that current ray position marks are realized; then, feedback calculation is carried out to obtain the length ratio of the current marking position of the center of the right lens relative to the actual 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 left lens center relative to the real length of the current mounting hole, and the length ratio of the current marking position of the right lens center relative 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 standard visual angle installation distance range of the model lens;

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

step S1051, the main controller obtains the real length of the current mounting hole, the length ratio of the current marking position of the left lens center relative to the real length of the current mounting hole, and the length ratio of the current marking position of the right lens center relative to the real length of the current mounting hole, thereby calculating the relative horizontal positions of the current left lens and the current right lens;

step S1052, calculating the actual distance between the current left lens and the current right lens at the initial position according to the relative horizontal position of the two lenses;

in step S1053, the gap distance of the left lens at the initial position with respect to the left edge of the mounting hole is calculated, and the gap distance of the right lens at the initial position with respect to the right edge of the mounting hole is calculated.

In the technical scheme of the application, according to the actual length of the current mounting hole, the length ratio of the current marking position of the left lens center relative to the actual length of the current mounting hole and the length ratio of the current marking position of the right lens center relative to the actual length of the current mounting hole, the relative horizontal positions of the current left lens and the current right lens are calculated; of course, the calculated value of the relative horizontal position of the current left lens and the current right lens is the actual distance between the two at the initial position; then calculating the clearance distance of the left side lens at the initial position relative to the left side edge of the mounting hole, and calculating the clearance distance of the right side lens at the initial position relative to the right side edge of the mounting hole; the purpose is to facilitate the mechanical clamping hand to insert into the gap to adjust the distance between the left side lens or the right side lens.

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

step S1061, a gap distance between the left side lens and the left side edge of the mounting hole in the initial position and a gap distance between the right side lens and the right side edge of the mounting hole in the initial position are called;

step S1062, determining one lens of the left lens or 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 clamping hand;

in step S1063, the operator starts the mechanical gripper to perform the horizontal displacement real-time random adjustment on the second horizontal mounting frame on the target adjustment lens, uses the current random adjustment position and the initial position of the other unadjusted lens as the initial positions of the two lenses in real time, and performs the subsequent judgment processing operation (corresponding to returning to step S104 to perform the subsequent operation) if the subsequent operation meets the standard viewing angle installation interval range.

It should be noted that, in the technical scheme of the 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 adjustment lens is calculated in a calculation mode, the mechanical clamping hand can not accurately move to the reasonable target position, so that the application adopts a real-time mode to carry out judgment processing, performs verification and detection while moving correction, and has better efficiency and better accuracy.

As shown in fig. 4, the present random adjustment position and the initial position of the other unadjusted lens are taken as the initial positions of the two lenses in real time, and the subsequent judging and processing operation of whether the standard viewing angle installation space range is met is executed, which specifically comprises the following steps:

Step S1065, the main controller acquires the real length of the current mounting hole, the length ratio of the current marking position of the left lens center relative to the real length of the current mounting hole and the length ratio of the current marking position of the right lens center relative to the real length of the current mounting hole in real time, and calculates 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 standard visual angle installation distance range of the model lens;

if the judgment result is no, the moving target adjusting lens in the preset horizontal moving direction is continued to return to the step S1064 for iterative execution.

In the technical scheme of the application, the mechanical clamping hand adjusts the lens in the preset horizontal moving direction by the moving target; the current random adjustment position of the target adjustment lens and the initial position of the other unadjusted lens are taken as the initial positions of the two lenses in real time; the two initial positions are then thereby redetermined, whereby the iterative process calculation is redefined.

During specific calculation, re-marking the laser rays, re-obtaining the real length of the current mounting hole, the length ratio of the current marking position of the left lens center relative to the real length of the current mounting hole, and the length ratio of the current marking position of the right lens center relative to the real length of the current mounting hole, and calculating the real distance between the current left lens and the current right lens at the initial position; judging whether the real distance at the initial position is within the standard visual angle installation distance range of the model of the lens;

if the judgment result is yes, determining that the current initial position is the target mounting position of the left lens and the right lens, and stopping the mechanical clamping hand to operate; and if the judgment result is that the target adjustment lens is not moved in the preset horizontal movement direction, the step S1064 is returned to be executed iteratively.

As shown in fig. 5, the determining the target adjusting 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 clamping hand specifically includes the following steps:

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

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

In the technical scheme of the application, the relation between the gap distance of the left side lens at the initial position relative to the left side edge of the mounting hole and the gap distance of the right side lens at the initial position relative to the right side edge of the mounting hole and the thickness distance of the mechanical clamping hand is judged; the reference factors which are convenient to move and have larger moving 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 larger gap distance is determined to be the target adjusting lens;

In a severe case, of course, if it is determined that the gap distance between the two lenses is smaller than the thickness distance of the mechanical gripper, the manual adjustment is performed to adjust the lenses.
