A calibration object is set, and locators are installed at the left and right wheels at the same time. After taking multiple groups of photos of the calibration object by the left and right positioning cameras respectively, the intermediate parameters between the calibration object image and the positioning camera that took the image are obtained by fitting the calibration disk image, so as to accurately measure the wheels of the truck.

[0018] The side end of the driving plate 6 is fixedly connected with multiple engaging teeth 7. The two driving plates 6 are located on both sides of the connecting gear 5. The engaging teeth 7 are meshed with the connecting gear 5. When installing the locator, first engage the engaging claw 4 on one connecting plate 3 with the edge of the wheel hub, and then pull the other connecting plate 3. At this time, the connecting gear 5 rotates, causing the two driving plates 6 to move at the same time, ensuring that the distance between the two connecting plates 3 and the connecting gear 5 is the same, so that truck gears with different diameters can be measured.

[0019] The side end of the extrusion plate 12 is fixedly connected with a plurality of extrusion blocks 16. The distance between two adjacent extrusion blocks 16 is the same. The top of the extrusion block 16 is provided with a friction plate. The side end of the connecting plate 3 is fixedly connected with a sliding block 10. The sliding block 10 is slidably connected to the inner wall of the guide groove 2. The middle of the adjusting screw 9 is threadedly connected to the connecting plate 3. The extrusion plate 12 and the auxiliary plate 8 move left and right. The adjusting groove 14 passes through the adjusting block 13. The adjusting groove 14 is tilted. The inner wall of the guide groove 2 is fixedly connected with a fixed column 15. The fixed column 15 is inserted into the adjusting groove 14. The two connecting plates 3 move At this time, the sliding block 10 moves in the guide groove 2. When the engaging claws 4 on the two connecting plates 3 are engaged with the edge of the wheel hub, the adjusting screw 9 is rotated, and the adjusting screw 9 drives the auxiliary plate 8 and the extrusion plate 12 to move vertically. The fixed column 15 blocks the movement of the extrusion plate 12. Guided by the adjusting groove 14, the extrusion plate 12 moves horizontally while moving vertically, so that the extrusion block 16 squeezes the sliding block 10, thereby limiting and fixing the two sliding blocks 10 and the connecting plate 3 to avoid the locator from falling due to accidental collision during measurement.

[0020] The width of the connecting plate 3 is greater than that of the mounting plate 1 , and the connecting plate 3 is an arc-shaped structure, which facilitates pulling the two connecting plates 3 to move while ensuring the field of view when the clamping claws 4 are clamped with the edge of the wheel hub.
