In the prior art, 360-degree panoramic calibration equipment almost adopts a fixed special target device, namely, a target pattern is fixed on the ground by spraying, and when the calibration learning of 360-degree panoramic functions is carried out on different vehicle models, a plurality of places are required to be provided with the target device and other corresponding parts, and the target device cannot be switched and the like to adapt to the calibration learning requirements of different vehicle models, so that the calibration cost of the 360-degree panoramic functions is higher.

In order to solve the problem that the calibration cost of a 360-degree panoramic function is high due to the fact that panoramic calibration equipment cannot meet the requirements of different vehicle models in the prior art, the invention provides the panoramic calibration device for the vehicle. Moreover, the panoramic calibration device can be used for calibrating and learning the 360-degree panoramic function of different vehicle types, so that the calibration cost of the 360-degree panoramic function is greatly reduced.

Referring first to fig. 1-3, an embodiment of the present invention provides a panoramic calibration apparatus for a vehicle, where the panoramic calibration apparatus 10 includes a target mechanism 11, a centering mechanism 12, a control mechanism, and the like.

Referring to fig. 1, in the embodiment provided by the present invention, the target mechanism 11 is disposed on both sides of the centering mechanism 12, and the control mechanism can control the operations of the target mechanism 11 and the centering mechanism 12. When a vehicle enters the centering and positioning mechanism 12, the target mechanisms 11 on both sides thereof are switched to target images for the vehicle to perform calibration learning of a 360-degree panoramic function.

Specifically, referring to fig. 2, the target mechanism 11 includes a frame 111, a first driving portion 112 and a second driving portion 113 disposed at two ends of the frame 111 and disposed opposite to each other along a horizontal plane, and a conveying portion 114 disposed around the first driving portion 112 and the second driving portion 113, where the conveying portion 114 has a first surface 1141 and a second surface 1142 disposed opposite to each other and connected end to end. A first mount having a first target image is removably mounted to the first surface 1141, a second mount having a second target image is removably mounted to the second surface 1142, and the first target image is different from the second target image. It can be understood that, when calibration learning is performed on two vehicles of different models, the conveying part 114 can be driven to transmit through synchronous rolling of the first driving part 112 and the second driving part 113, so that the first target image and the second target image on the conveying part 114 can be switched, and calibration learning of two vehicles of different models is satisfied. When calibration learning is carried out on the vehicles of the third type, the fourth type and even the more types, only the first installation part and/or the second installation part are needed to be replaced, and the installation parts are provided with different target images, so that the calibration learning of the vehicles of different types can be met.

It is understood that in this embodiment, the length of the steel plate should be no less than the length of the first target image and the second target image, so as to ensure that the first target image on the first surface 1141 and the second target image on the second surface 1142 of the conveying part 114 are maintained horizontally.

In addition, in a possible embodiment, the supporting portion 115 may include a plurality of steel plates, a connecting member, and a side plate, a first surface of the supporting portion 115 is formed by connecting several steel plates together through the connecting member, and similarly, a second surface of the supporting portion 115 is formed by connecting several steel plates together through the connecting member, and finally, the supporting portion 115 is formed by connecting the side plate to both sides of the steel plates.

In the possible embodiments described above, the length of the support 115 is 6-8m, i.e. the length of the first target image and the second target image is less than the above-mentioned length range. For example, if the length of the first and second target images is 5m, the length of the support 115 may be, but is not limited to, 6m, 6.1m, 6.2m, 6.3m, 6.4m, 6.5m, 6.6m, 6.7m, 6.8m, 6.9m, 7.0m, 7.1m, 7.2m, 7.3m, 7.4m, 7.5m, 7.6m, 7.7m, 7.8m, 7.9m, 8.0 m.

In one possible embodiment, the first mounting element having the first target image can be a first piece of cloth made of polyethylene resin, and the second mounting element having the second target image can also be a second piece of cloth made of polyethylene resin.

Further, the first fabric sheet is detachably mounted on the first surface 1141 of the conveying portion 114, and the second fabric sheet is also detachably mounted on the second surface 1142 of the conveying portion 114, and in the embodiment of the present invention, there is no particular limitation on the specific detachable mounting manner. In a particular embodiment, a first piece of cloth is adhered to first surface 1141 and a second piece of cloth 1142 is adhered to second surface 1142.

In the embodiment provided by the present invention, there is no particular limitation on the conveying part 114 as long as a horizontal surface can be formed. In one possible embodiment, the conveyor 114 is a crawler.
