Referring to fig. 1 and 2, fig. 1 is a block diagram showing a basic architecture of an automatic aiming correction system of an optical aiming device according to an embodiment of the present invention, and fig. 2 is a schematic diagram showing a usage scenario of the automatic aiming correction system of the optical aiming device according to an embodiment of the present invention.
Fig. 1 and 2 show an automated aiming correction system of an optical aiming device 14, which is suitable for controlling an optical aiming device 14 to aim a target object 100, the system includes, but is not limited to, a multi-axis controller 11, an image capturing device 12, a central control unit 13, and a mobile device 15, wherein the central control unit 13 is electrically connected to the multi-axis controller 11, the image capturing device 12, the optical aiming device 14, and the mobile device 15 is used for controlling the movement of the optical aiming device 14.
The multi-axis controller 11 is used for fixing the optical pointing device 14, and the multi-axis controller 11 can control the optical pointing device 14 to output a projection angle of the projection light 141.
The projection light 141 projected by the optical sighting device 14 may be visible light or invisible light, and the projection light 141 projected by the optical sighting device may be detected. The optical pointing device 14 may thus be an optical projection (shooting) device, of the type in which the projected light is visible, for example a bar code scanner, and of the type in which the projected light is invisible, for example an invisible light laser emitting device. The optical pointing device 14 is, for example, a bar code scanner, and the shape of the projected light 141 projected onto the target object 100 is not necessarily circular, but may be a cross, a straight line, a plane, or the like (as exemplified by a cross in fig. 2).
In an embodiment, the multi-axis controller 11 can be at least two axial holders, and the multi-axis controller 11 is electronic and can rotate to adjust the angle after receiving the control signal. And the object 100 may be a one-dimensional, two-dimensional bar code or any other identifiable electronic tag.
The image capturing apparatus 12 may extract an image of the target object 100, where the image of the target object 100 may include an image around the target object 100, but is not limited thereto. Also, thus, after the optical pointing device 14 projects the projection light 141 onto the target object 100, the image capturing device 12 may extract an image including the target object 100 and the projection light 141 on the target object 100.
In one embodiment, the setting position of the image capturing device 12 relative to the target object 100 is a fixed position, so as to continuously and fixedly extract the image of the target object 100 to be tested.
In an embodiment, the central control unit 13 may be a computer device or a portable electronic device with operation capability.
Referring to fig. 3, fig. 4 and fig. 5, fig. 3 shows a schematic diagram of first image data formed by extracting an image of a target object according to an embodiment of the invention, fig. 4 shows a schematic diagram of second image data formed by extracting the target object and projecting an optical image onto the target object according to an embodiment of the invention, and fig. 5 shows a schematic diagram of image difference data formed by analyzing and comparing the first image data and the second image data according to an embodiment of the invention.
Fig. 3 illustrates a first image data 200 obtained by extracting an image of the object 100 by the image capturing apparatus 12. As shown in fig. 4, after the optical pointing device 14 projects the projection light 141 onto the target object 100, the image capturing device 12 is made to extract the image including the target object 100 and the projection light 141 on the target object 100 to form a second image data 300.
In one embodiment, in conjunction with fig. 2, the first image data 200 obtained by the central control unit 13 indicates that the projection light 141 must fall at a default position of the target object 100 (such that the projection light 141 output by the optical pointing device 14 falls at a default position of the target object 100). In other words, the central control unit 13 can define where the default position is located in the image, such as the center point or any position of the object 100 on the image, for the image analysis of the first image data 200.
Therefore, in order to extract the first image data 200 and the second image data 300 for comparison and analysis, the central control unit 13 may control the image capturing device 12 to extract the images and obtain the first image data 200 and the second image data 300 respectively, and analyze and compare an image difference formed by the first image data 200 and the second image data 300 to form an image difference data 400 (fig. 5), wherein the image difference is the relative position between the projected light 141 and the default position 500, and the control basis for adjusting the multi-axis controller 11 according to the image difference.
In one embodiment, after the first image data 200 is extracted, the background images except the target object 100 may be deleted in advance in the image processing to reduce the interference of the image comparison analysis.
Referring to fig. 6, 7 and 8, fig. 6 shows an operation diagram of adjusting a projection position of a projection light onto a target object according to an image difference and performing a longitudinal displacement correction according to an embodiment of the present invention, fig. 7 shows an operation diagram of adjusting a projection position of a projection light onto a target object according to an image difference and performing a transverse displacement correction according to an embodiment of the present invention, and fig. 8 shows an operation diagram of adjusting a projection position of a projection light onto a target object according to an image difference and performing a correction for enabling a projection position of a projection light to reach a default position according to an embodiment of the present invention. Therefore, with reference to fig. 2 and 5, after the central control unit 13 analyzes the image difference data 400 formed by comparing the first image data 200 and the second image data 300 (as shown in fig. 5), the central control unit 13 determines whether the projection position (i.e. the position of the projection light 141) is equal to the default position 500 (assuming that the default position 500 is located at the center of the target object 100).
Therefore, according to the image difference data 400, when the central control unit 13 determines that the projection position of the projection light 141 is not equal to the default position 500, the central control unit 13 generates an adjustment signal according to a first distance difference 161 and a second distance difference 162 between the projection position and the default position 500, and outputs the adjustment signal to the multi-axis controller 11, and the multi-axis controller 11 adjusts the projection angle of the projection light 141 (i.e. the position of the displacement projection light 141) of the optical pointing device 14 according to the adjustment signal, so that the projection position of the projection light 141 falls at the default position 500. The embodiment in which the projection angle of the projection light 141 of the optical pointing device 14 is adjusted by the longitudinal downward displacement and the lateral rightward displacement is merely illustrative, and the adjustment of the projection angle of the projection light 141 and the adjustment of the position of the projection light 141 are not limited thereto.
In one embodiment, the image difference is the image difference data 400 obtained by the central control unit 13 by performing image processing on both the first image data 200 and the second image data 300 by image subtraction (Image Subtraction) to obtain a projection position of the projection light 141 on the object 100.
In one embodiment, the projection angle of the projection light 141 of the optical pointing device 14 is adjusted by performing a proportional estimation according to the pixel difference of the image difference data 400. The pixel difference ratio can be calculated by matching with the trigonometric function, but is not limited thereto.
In an embodiment, referring to fig. 2, when the mobile device 15 is further included, the multi-axis controller 11 is disposed on the mobile device 15, and the central control unit 13 controls the distance between the optical pointing device 14 and the target object 100 by controlling the mobile device 15. Thereby, the linear movement of the optical pointing device 14 is controlled by the movement device 15 before the correction is made by adjusting the projection angle of the projection light 141 of the optical pointing device 14.
Referring to fig. 1 to 8, in conjunction with fig. 9, fig. 9 shows a flow of an automatic aiming correction method of an optical aiming device according to an embodiment of the present invention.
In this process, in step S901, the optical pointing device 14 is moved to a specified position, and according to the above embodiment, the target 100 is set at a substantially fixed position, and when a single target 100 is tested, the optical pointing device 14 is moved to the specified position.
Then, in step S903, an image of the target object 100 is extracted by the image capturing device 12 to form a first image data 200, and according to one embodiment, in cooperation with the first image data 200 obtained by the central control unit 13 as shown in fig. 2, 3 and 5, a default position 500 where the optical pointing device 14 projects the projection light 141 onto the target object 100 is determined, where the default position 500 may be a center point or any position on the target object 100.
In addition, in step S905, the central control unit 13 controls the optical pointing device 14 to output a projection light 141 onto the target object 100, and according to an embodiment, in cooperation with fig. 2, the projection light 141 is projected (shot) by the optical pointing device 14 fixed to the multi-axis controller 11.
Then, in step S907, the image capturing apparatus 12 is used to extract the image including the object 100 and the projection light 141 on the object 100 to form the second image data 300, and according to an embodiment, the second image data 300 can be repeatedly extracted to serve as multiple sets of comparison data of the first image data 200.
In step S909, the central control unit 13 obtains the first image data 200 and the second image data 300, and analyzes and compares an image difference formed by the first image data 200 and the second image data 300 to form image difference data 400 (fig. 5), wherein the image difference is, for example, a pixel difference, that is, whether there is movement or difference of an object in the image is determined, so as to determine the actual projection position of the projection light 141.
In step S911, it is determined whether the projection light 141 falls at the correct position (whether the projection position of the projection light 141 is equal to the default position 500) according to the image difference data 400, and in accordance with fig. 2 and 5, that is, according to the image difference data 400, the multi-axis controller 11 is adjusted, if the projection light 141 falls at the correct position (that is, the projection position of the projection light 141 is equal to the default position 500), step S913 is performed, and the adjustment correction of the projection light 141 is not performed.
Otherwise, if the projection light 141 does not fall at the correct position (i.e. it is determined that the projection position of the projection light 141 is not equal to the default position 500), step S915 is performed, and the projection angle of the projection light 141 is adjusted according to the image difference data 400, according to an embodiment, the multi-axis controller 11 is enabled to control the optical pointing device 14 to output the projection angle of the projection light 141, so as to adjust the correction of the projection light 141 to the correct position, i.e. generate an adjustment signal according to a distance difference between the projection position of the projection light 141 and the default position 500, and output the adjustment signal to the multi-axis controller 11, and the multi-axis controller 11 is enabled to adjust the projection angle of the projection light 141 of the optical pointing device 14 according to the adjustment signal, so that the projection position of the projection light 141 falls at the default position 500. After the calibration in step S915 is completed, step S903 may be performed again.
In an embodiment, in step S909, the image difference data 400 is obtained by subtracting the first image data 200 and the second image data 300 from each other, and the first image data 200 and the second image data 300 may be images subjected to trapezoidal correction (Keystone adjustment), so that the first image data 200 and the second image data 300 conform to the parallelogram image frame, which can solve the problem of image skew after the image capturing device 12 extracts the images, for example, horizontal or vertical correction.
In one embodiment, in step S915, when the projection angle of the projection light 141 is adjusted according to the image difference data 400, the actual values of the first distance difference 161 and the second distance difference 162 are calculated by using the target object 100 with a known size, and the corrected angle of the projection light 141 is calculated by adding the distance between the optical pointing device 14 and the target object 100 based on the actual values. Wherein the central control unit 13 controls the distance between the optical pointing device 14 and the target object 100 by controlling the mobile device 15.
