Automobile position auto-induction apparatus

Abstract

The invention discloses a device for automatically inducting automobile positions. The device comprises at least three automobile position inductors, wherein the first, the second and the third automobile position inductors are respectively embedded in the road surface before an automobile running into the station of a headlamp aligner, the first automobile position inductor and the second automobile position inductor are arranged vertical to a left driving guide line and a right driving guide line, the distance between the first automobile position inductor and a guide rail of the headlamp aligner is equal to the distance between the second automobile position inductor and the guide rail of the headlamp aligner, the third automobile position inductor is arranged in front of or behind the first automobile position inductor or the second automobile position inductor and is vertical to one of the left and the right driving guide lines, and each automobile position inductor is provided with an automobile position induction unit. The device can induct the position of the detected automobile automatically and calculate the offset angle of the driving direction of the detected automobile and the driving guide line of a detection line automatically, so as to correct detection data of a headlamp to greatly reduce the errors of the detection data. The device has the advantages of simple structure, small equipment volume, and greatly reduced cost.

Description

Technical field: [0001] The invention relates to automobile detection technology, in particular to an automobile position automatic sensing device used on the automobile safety performance detection line to automatically detect the position of the automobile entering the headlamp detection station. Background technique: [0002] In order to ensure the safety of the car at night, it is required that the car headlights have sufficient luminous intensity and accurate illumination direction. GB7258-2004 "Technical Conditions for Safety of Motor Vehicle Operation" has made clear regulations on this, and the car safety performance testing stations in various places also Check this item as a mandatory item for the annual inspection of automobiles. [0003] Usually, a fully automatic automobile headlamp detector is used to detect automobile headlamps. The instrument runs on a dedicated rail, automatically searches for the headlamp to be inspected, and automatically detects the luminous i...

Problems solved by technology

However, this method fails to solve the problem of how to extract the body image when the color of the inspected car is similar to the ground color

Moreover, due to the deformation of the body of some cars, the direction of the central axis of the body image deviates from the actual driving direction of the car, which will also cause errors in the detection results of the car headlight detector.
