[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-6 , the utility model provides a robot sensor calibration device:
[0021] See Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 As shown, a robot sensor calibration device includes a pillar 1, an electric telescopic pillar 2 is fixedly installed on one side of the pillar 1, a connecting rod 3 is fixedly installed on the bottom of the telescopic end of the electric telescopic pillar 2, a motor 4 is fixedly installed on the bottom of the connecting rod 3, the rotating end of the motor 4 is fixedly connected to a rotating rod, and an adjustment frame 5 is fixedly installed on the bottom of the rotating rod.
[0022] The electric telescopic column 2 can be extended and retracted, and the motor 1 4 can rotate the rotating rod, thereby driving the adjustment frame 5 to rotate.
[0023] Figure 5 In order to see it clearly, the uncorrected goods are not attached to the adjustment frame 5. The goods actually used should be attached to the adjustment frame 5.
[0024] See Figure 1 A base plate 6 is fixedly installed at the bottom of the pillar 1, a pillar 2 7 is fixedly installed on the side of the base plate 6 close to the pillar 1, a calibration frame 8 is fixedly installed on the top of the pillar 2 7, a strip opening is opened on the calibration frame 8, and a calibration body 9 is fixedly installed in the strip opening.
[0025] Calibration frame 8 secures calibration unit 9, which includes a CCD camera. Within the calibration device, the CCD camera primarily captures the calibration pattern or object and acquires image data. By comparing and analyzing this image data, internal and external camera parameters, such as focal length, distortion coefficients, rotation matrix, and translation vector, can be calculated. This system offers high resolution, high sensitivity, and excellent image stability.
[0026] The CCD (charge-coupled device) is the core photosensitive element of a camera. It converts incident light into electrical signals. Each pixel on the sensor generates a corresponding charge upon receiving light. This charge is then converted into an electrical signal, which is then transmitted and processed by circuitry. The coordinated operation of the entire CCD sensor captures complete image information. This image information exists as an electrical signal and can be further processed, stored, or transmitted. When the calibration unit 9 is operating, light passes through the camera lens and is projected onto the CCD sensor. Each pixel on the sensor captures the corresponding light information and converts it into an electrical signal. These electrical signals are then processed by the camera's internal circuitry to form a complete image.
[0027] The calibration body 9 contains a CCD camera in order to achieve accurate position and angle measurement of the object. Camera calibration is the process of obtaining camera model parameters. These parameters describe the internal geometry of the image capture process and are the basis for subsequent position and angle measurement. Qualified object positions and angles are used for calibration. By taking an image of the calibration object and extracting feature points on the calibration object using an image processing algorithm, the internal and external parameters of the camera are calculated based on the image coordinates of the feature points and the known three-dimensional coordinates, and the camera's focal length, principal point position, distortion coefficient and other parameters are obtained. A camera imaging geometric model is established, and three-dimensional reconstruction is performed using the parameters obtained by camera calibration and the feature points extracted by image processing to obtain the position information of the object to be measured in three-dimensional space. Based on the position information obtained by three-dimensional reconstruction, the specific position of the object to be measured in three-dimensional space can be determined. By comparing the position and angle of qualified objects, the position offset and position of the object relative to a reference point can be obtained.
[0028] See Figure 1 、 Figure 3 、 Figure 4, four feet 10 are fixedly installed on the top of the base plate 6, and a support column 11 is fixedly installed on one side of the foot 10. A motor 2 12 is fixedly installed on the top of the support column 11, and the rotating end of the motor 2 12 is fixedly connected to a rotating shaft 13. A protective shell 14 is fixedly installed on the top of the foot 10, and a circular opening is opened on the protective shell 14. The rotating shaft 13 is the same size as the circular opening, and a pulley 15 is fixedly installed on one side of the rotating shaft 13. A belt 16 is provided on one side of the protective shell 14, and the protective shell 14 is covered on the side edge of the belt 16, and the belt 16 is sleeved on two pulleys 15.
[0029] The second motor 12 can drive the rotating shaft 13 to rotate, so that the pulley 15 rotates, thereby driving the belt 16 to rotate and transport the goods. The protective shell 14 can protect the pulley 15 and prevent the pulley 15 from being damaged due to bumps and other reasons, thereby affecting normal operation.
[0030] See Figure 2 A shipping port 17 is fixedly installed on one side of the bottom plate 6 close to the pillar 1.
[0031] Four shipping channels are provided on the shipping port 17, and each channel is the same size as the goods.
[0032] See Figure 1 A console 18 is fixedly mounted on one side of the base plate 6 close to the second pillar 7 , and a control panel 19 is fixedly mounted on one side of the console 18 .
[0033] The control panel 19 is connected to the electric telescopic column 2, motor 1 4, calibration body 9, motor 2 12, and buzzer 20 for signal connection, so as to facilitate control.
[0034] See Figure 1 A buzzer 20 is fixedly installed on one side of the console 18.
[0035] When goods that do not belong to this production line appear on the belt 16, the buzzer 20 will receive a signal from the calibration body 9 and then start to operate to remind the staff.
[0036] Working principle: When the goods are transported to the belt 16 by the outside, the staff turns on the robot sensor calibration device through the control panel 19. At this time, the calibration body 9 starts to operate, and the motor 2 12 starts to drive the shaft 13 to rotate, so that the pulley 15 rotates, thereby driving the belt 16 to rotate, so that the goods begin to follow the operation of the belt 16 and move toward the delivery port 17. When the goods pass through the calibration body 9, the calibration body 9 scans the goods, determines the position and placement angle of the goods, and then sends a signal to the control panel 19. The control panel 19 controls the electric telescopic column 2 and Motor 14 runs to extend and retract the electric telescopic column 2, and the positioning frame 5 comes to the unqualified cargo area. Then, the motor 14 controls the rotation of the positioning frame 5 to adjust the entrance direction of the positioning frame 5 and put the cargo into the positioning frame 5. Then, the motor 14 rotates to rotate the positioning frame 5 and adjust the angle of the cargo. Then, the control panel 19 controls the electric telescopic column 2 to align the cargo with the delivery channel of the delivery port 17 for delivery. When cargo that does not belong to this assembly line appears on the belt 16, the buzzer 20 receives a signal from the calibration body 9 and starts to operate to remind the staff.
