Chassis gap detection device is widely used for testing the value of chassis gap. According to the disability of detecting chassis gap efficiently and precisely, a novel chassis gap detection device adopts double-rocker construction is proposed. For ensuring the good performance of the tester, the transmission and tester model is established in ADAMS to simulate the dynamics feature of the detection...
The research of the wheel alignment system based on computer vision is a popular field for automobile safety. For realizing the effective and accurate feature recognition for the chessboard calibration target of the system, the enhancement algorithms based on Gamma correction are indicated. According to the research object, identification requires decreasing the pixel values in low grayscale and increasing...
The research of feature corner recognition for the calibration target is a crucial area for a vision-based measurement system. For the disability of detecting the corner's location in a vehicle test system accurately, the theoretical errors based on Harris algorithm are analyzed. Experimental results show that the method can not be used in the vision-measured field as the corner cluster phenomenon...
Feature matching is a crucial research in computer vision. For realizing the effective and accurate feature matching for the feature points in the images of chessboard calibration target used in the wheel alignment system, the popular calculation algorithms are analyzed. The traditional polar constraint and polar equation for solving the problem constructing the relationship between corresponding...
The research of calibration model for the wheel alignment system is a crucial area for automobile safety. For the disability of calibrating measurement results of wheel alignment system, the theoretical errors based on the superposition principle are analyzed. Simulation results show that the errors are more than 0.4deg whereas the common precision of wheel alignment system is 0.02deg. Novel calibration...
