Abstract

The invention provides an automobile instrument automatic detection device and method based on machine vision. The device comprises a test system equipment cabinet, an instrument panel and a transmission positioning unit thereof, an image collection visual component, an upper computer image processing program and a system test program. The instrument panel and the transmission positioning device thereof are used for positioning and supporting the instrument panel to complete detection when the instrument panel under test enters the detection device via an assembly lime. An industrial control machine controls the instrument panel under test to execute a corresponding display action via CAN communication. The image collection visual component comprises an industrial camera, a prime lens, a dark box and a fixing rack; image data collected by the industrial camera is uploaded to the industrial control machine; the industrial control machine judges whether the instrument panel under test has a display defect and generates a test report via image treatment and analysis. Based on the automobile instrument automatic detection device and method based on machine vision, the non-contact typeautomatic measurement is achieved, the labor cost is reduced, and meanwhile, the degree of automation and running efficiency of the production line are enhanced.

Description

technical field [0001] The invention belongs to the field of image processing and the field of integration of automobile electronic automatic test systems, and in particular relates to a machine vision-based automatic detection device and method for automobile instrumentation. Background technique [0002] The car dashboard is a device that reflects the working status of each system. With the development of the automobile industry, the car dashboard gradually transitions from the traditional pointer type to the liquid crystal digital display type. Full LCD instrument screen has gradually become the trend of the current car instrument panel. At present, the instrument panel of many new models adopts full liquid crystal display or a combination display method of LCD liquid crystal combined with some LED icons. At the same time, the information required to be displayed by automotive instrumentation is becoming larger and larger, and the automotive instrumentation system is also...
