Remote control method and remote control system for car wheel locator

Abstract

The invention discloses a remote control method for a car wheel locator. The remote control method includes a first step of obtaining patterns obtained through real-time shooting of a camera on locating targets with a plurality of feature points, a second step of judging the frequencies that all the feature points in the patterns do not appear within N seconds, and a third step of driving a computer system and enabling car wheels corresponding to the patterns to enter corresponding measuring states according to the frequencies. The invention further discloses a remote control system for the car wheel locator. Through utilization of the error reporting principle of the locator identifying the locating targets, the method or the system can carry out remote control, namely, when the error frequencies of the locator for identifying the locating targets reach a certain preset value, the method or the system can be used for driving the computer system and enabling the corresponding car wheels to enter the corresponding measuring states according to a preset processing mechanism, and an operator does not need to go out from the bottom of a car and comes to a computer console to operate, so the method or the system is quite convenient and fast, and greatly improves adjusting efficiency, prevents adjusting errors from being caused, and reduces working burden of the operators.

Description

[0001] technical field [0002] The invention relates to a remote control method and system for an automobile wheel aligner. [0003] Background technique [0004] The car wheel locator obtains the wheel positioning data by measuring the spatial position parameters of the four positioning targets installed on the four wheels in the camera system coordinate system. The specific working principle is: the computer system uses the camera to The positioning target with multiple feature points is photographed, and the captured pictures are sent to the computer system for comprehensive calculation. Since each positioning target has a special geometric pattern, the computer system compares the positioning target according to the pattern captured by the camera. Analyze the feature points on the target and distinguish the four positioning targets (corresponding to the four wheels) of the left front, right front, left rear, and right rear, and perform spatial three-dimensional geometr...

Problems solved by technology

[0005] However, when adjusting the four-wheel alignment parameters of the vehicle, the operator is usually located at the bottom of the vehicle for adjustment work. When certain functions are needed, such as when adjusting the left rear wheel alignment parameters, the operator is far away from the computer monitor (usually is about 5 meters), the real-time measurement data on the display will not be seen clearly. At this time, the operator needs to come out from the bottom of the vehicle and return to the computer console to operate, which greatly affects the adjustment efficiency and is easy to cause adjustment errors due to vision. In addition, when the operator is adjusting the vehicle, he usually wears work gloves, which will inevitably be stained with oil, dust, etc., so if the operator goes back and forth between the bottom of the vehicle and the computer console, it will be very troublesome , which increases the workload of the operator and further reduces the adjustment efficiency
