After-sales calibration-free method and system for host of vehicle look-around system

Abstract

The invention relates to an after-sales calibration-free method and system for a host of a vehicle look-around system. The method comprises the following steps: storing calibration information of thelook-around system host to a local place of the host of the look-around system and a mobile storage medium of the host of the look-around system; when the host of the look-around system is restarted,reading whether calibration information is stored in the mobile storage medium or not, and when no calibration information is stored and the calibration state is a calibrated state, importing the calibration information in the mobile storage medium to the host of the look-around system locally; when the host of the look-around system is replaced, implanting an original mobile storage medium into ahost of a new look-around system and importing calibration information in the original mobile storage medium into the local of the host of the new look-around system after authority verification is passed. The after-sales service efficiency can be greatly improved during after-sales service, the tedious process that a calibration tool and calibration cloth need to be carried to a specified after-sales outlet for complex after-sales calibration in the after-sales market is avoided, the after-sales cost is reduced, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle electronic products, in particular to an after-sales calibration-free method and system for a host computer of a vehicle surround view system. Background technique [0002] At present, more and more vehicles are equipped with a surround view imaging system, which collects video images around the vehicle through cameras installed around the vehicle, and stitches them into a surround view video screen, which is convenient for drivers to observe surrounding images and drive safely. A surround view imaging system usually consists of a host and multiple cameras. Surround view host requires built-in detachable SD, TF and other storage media for video storage requirements. Usually, the surround view imaging system needs to be calibrated when it leaves the factory. When the factory goes offline, the factory can build a standard site for calibration. However, in the after-sales market, it is inevitable t...

Problems solved by technology

However, in the after-sales market, it is inevitable that the surround view image host fails or cannot be used normally for other reasons, resulting in the need to replace the surround view image host. In this case, professional after-sales personnel usually bring special calibration tools, calibration cloth, etc. The equipment rushes to the site for calibration services. This after-sales service method has the disadvantages of low efficiency and high service costs.
