A kind of manufacturing method of calibration gold sample for optical axis inspection machine of vehicle-mounted camera

Abstract

The invention discloses a method for making a calibration gold sample for a vehicle-mounted camera optical axis inspection machine. Using the principle of concentricity and coaxiality, firstly a laser pointer combination module with the same size as the camera is made. When the laser pointer and the fixed module are horizontally fixed Form a laser pointer module, and then fix the laser pointer module horizontally with the fixed base, and finally ensure that the laser pointer combination module is placed flat with the optical axis inspection machine, and the laser pointer is emitted to the laser point, which is the center of the optical axis inspection machine. The present invention adopts a completely different concept mode in the past to calibrate the center position of the optical axis inspection machine. The present invention abandons the calibration mode dominated by the camera, but adopts a method closer to the naked eye observation, and directly finds the optical axis through the emitted light Compared with the previous method, it is a set of convenient and quick calibration method with simple calibration process, low cost and accurate calibration method.

Description

technical field [0001] The invention relates to the technical field of a vehicle-mounted camera optical axis inspection machine, and more specifically relates to a method for preparing a calibration gold sample for a vehicle-mounted camera optical axis inspection machine. Background technique [0002] As the demand for automobiles continues to increase, various automobile manufacturers establish their own advantages by continuously introducing advanced automobile safety systems. As a part of car safety, car cameras are gradually being introduced into car systems by various car manufacturers. Because of their outstanding performance, their prospects are brighter. As a company that produces car cameras, whether we can achieve the relevant functions of car cameras is the focus of whether we can gain a foothold in this industry. Since the car camera started relatively late, its corresponding theoretical foundation is not solid, and its production experience is not rich. Corres...

Problems solved by technology

This method currently has two major shortcomings: First, the production process of camera standard products is very time-consuming and laborious, because there is no standard to refer to, so standard testing and production can only be carried out step by step

Once there is an error in one step, the whole process will be wrong, so it will cause huge losses in production

Secondly, when calibrating with the produced camera standard products, a large amount of software needs to be used. For the analysis of the software, summarizing the numbers generated by the software will make the whole process very cumbersome. If the software makes errors, it will directly lead to the optical axis. The inspection machine detects defective products, which puts a lot of pressure on production
