The driving device is a mechanical arm. The image acquisition device 5 is a camera. The server 6 and the driving device perform data transmission through an RF433 wireless transmission module or a ZIGBEE wireless transmission module.
The illumination direction of the illumination device 1 is located within the specific area 10.
The server 6 includes an input end and an output end, wherein the input end is electrically connected to the image capturing device 5, and the output end is electrically connected to the driving device.
In the actual use process, the lighting direction of the lighting device 1 can be changed by manually controlling the driving device, the lighting direction of the lighting device 1 can be automatically controlled by the server 6, and the server can be arranged in the lighting equipment or an external device can communicate information with the lighting equipment.
The server 6 includes: the image processing device comprises an image detection unit, an area detection unit, a proportion calculation unit, a control unit, a calculation unit and a judgment unit.
The image detection unit is used for acquiring pixel coordinate information of the target to be tracked in the real-time image. Specifically, the real-time image captured by the image capturing device 5 is a two-dimensional plane image. In one embodiment, the real-time image has a fixed resolution of 640 × 480, so that the pixel coordinate information of the target to be tracked in the real-time image is determined by the resolution. In order to better identify the position of the target to be tracked, the boundary of the target to be tracked in the environment is acquired.
The image detection unit includes: the image processing device comprises a coordinate acquisition unit, an image partition unit, a boundary acquisition unit and a pixel coordinate acquisition unit.
The coordinate acquisition unit is used for acquiring the centroid pixel coordinate of the target to be tracked. Specifically, in one embodiment, the centroid is a centroid of a color feature of the target to be tracked. For example, the facial features of the target to be tracked can be identified, and the coordinates of the centroid pixel of the target to be tracked can be determined.
The image partition unit divides the real-time image into a plurality of regions with the centroid pixel coordinate as an origin. Specifically, the centroid pixel coordinate is located in a two-dimensional plane of the real-time image, and in an embodiment, a cartesian coordinate system is established in the two-dimensional plane with the centroid pixel coordinate as an origin to divide the real-time image into four regions. And each region is respectively scanned from the origin to the outside in a scattering manner, and the boundary of the target to be tracked is searched simultaneously. The boundary search of the target to be tracked meets the following conditions:
where G denotes the gradient value of the pixel P, T denotes the gradient adaptive threshold, E0The method refers to the result of searching the boundary of the target to be tracked, wherein 0 represents that the target is not in the target area, 1 represents that the target is in the target area, and R represents0The target area to be tracked is shown.
The boundary acquisition unit is used for respectively scanning each region to acquire boundary pixel coordinates of each region. Specifically, when each of the regions is scanned, the centroid pixel coordinate is used as the origin.
And the pixel coordinate acquisition unit generates pixel coordinate information of the target to be tracked according to the boundary pixel coordinate of each region. Specifically, the boundary pixel coordinates of each of the regions include a plurality of pixel coordinates, and the pixel coordinate information generated by the boundary pixel coordinates of each of the regions is a finished face contour when scanning is performed scattered outward from an origin in a normal case without an error.
And when the pixel coordinate information of the target to be tracked changes, the calculating unit is used for calculating the difference value of the change of the pixel coordinate information. Specifically, when the pixel coordinate information is an initial value, the difference does not need to be calculated.
The judgment unit is used for judging whether the absolute value of the difference value is larger than a preset threshold value or not, and if so, recalculating the actual position information by the changed pixel coordinate information. Specifically, in practical tests, it is found that even if the target to be tracked in the specific area 10 is still, the pixel coordinate information given by the image acquisition device 5 in the real-time image fluctuates within a certain range, so that the tracking device shakes. The pixel coordinate information therefore varies within a certain range without changing the orientation of the tracking device. And if the absolute value of the difference is larger than a preset threshold, recalculating the actual position information by using the changed pixel coordinate information.
The area detection unit is used for calculating the actual size of the specific area 10 according to the position of the image acquisition device 5. Specifically, by calculating L ═ L1+ L2,
according to the formula
L2＝H(tan(@1+@2))-tan(@1))
From this, the (x0, y0) coordinate is calculated as (b, L), i.e.
The proportion calculation unit is used for calculating the proportion relation between the pixel size of the real-time image and the actual size of the specific area 10. Specifically, the size of the specific area 10 is (b, L), so that the actual distance represented by each pixel can be calculated.
And the control unit is used for calculating the actual position of the target to be tracked according to the proportion information and the pixel coordinate information, calculating according to the actual position of the target to be tracked, and sending a control command according to the actual angle of the tracking device and the actual angle of the tracking device when the target to be tracked is tracked.
In particular, the method comprises the following steps of,thus, the P point pixel coordinate is converted into the actual position, and the result is (xL2/640, yb/480), namely
Therefore, the actual position of the point P is only related to the values of H, @1, @2 and @3, and the three values are fixed values, so that the final user only needs to adjust the installation height and the angle according to the requirement, and the difficulty of field debugging is greatly reduced. The actual angle is recognizable by the driving means so that the driving means adjusts the angle of the tracking means. And sending the control instruction to a driving device, wherein the driving device changes the direction of the tracking device according to the control instruction.
As shown in fig. 2, with O as the origin, the Z axis in the height H direction, the X axis in the width L direction, and the Y axis in the same plane with the specific region 40 and perpendicular to the width L direction, the image capturing device 10 is assumed as point C, where the height 10 of the image capturing device is the perpendicular distance between the image capturing device and the plane of the specific region H (i.e., the distance between the image capturing device 10 and point O), L1 is the distance between point O and point a, L2 is the distance between point a and point B, and B is the distance between point B and the coordinates (X0, Y0). @1 is the angle between AC and OC. The included angle between @2AC and BC, and the @3 is the included angle between BC and C and the line connecting the coordinates (X0, Y0).
A driving device is connected to the lighting device 1 for changing the lighting direction of the lighting device 1. In an embodiment, the driving device is a robot, which can control the position and illumination angle of the lighting device 1 in three dimensions. The lighting device 1 and the image capturing device 5 are slidably mounted to the guide rail 13, respectively.
