Abstract

The invention discloses a bicycle rack measuring method. The bicycle rack measuring method comprises the steps of firstly, fixing a bicycle rack on a working platform, then mounting a rear wheel shafttool on a rear lower fork of the bicycle rack, utilizing a front camera to capture a front-view image of a head tube, utilizing an upper camera to capture an upper-view image of the rear wheel shafttool, utilizing a rear camera to capture a rear-view image of a rear wheel shaft, analyzing the captured images to obtain a front-view axis of the head tube, the upper-view axis of the rear wheel shaft tool and the rear-view axis of the rear wheel shaft, comparing the front-view axis of the head tube with a preset datum line, comparing the upper-view axis of the rear wheel shaft tool with a presetdatum line, comparing the rear-view axis of the rear wheel shaft with a preset datum line, and further judging whether included angle among the axes are within an acceptable range. Thereby, the bicycle rack measuring method has the advantages of fast operation and high precision.

Description

technical field [0001] The invention relates to the measurement technology of the bicycle frame, in particular to a measurement method of the bicycle frame. Background technique [0002] Regardless of whether it is a metal frame or a carbon fiber frame, both may cause the frame to shift and deform due to poor workmanship. Therefore, each frame factory will randomly test some frames during the frame production process. The measurement (such as offset). However, the current measurement methods are mainly operated by the measurement personnel with calibration tools and measurement tools (such as height gauges), but the professional level of each measurement personnel is different. The location of the energy measurement is limited, so the manual measurement method is not only too time-consuming, but also prone to large errors in the measurement results of the frame. Contents of the invention [0003] The main purpose of the present invention is to provide a method for measur...
