Embodiment Construction

[0026] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] Such as figure 1 , image 3 , Figure 4 As shown, the present invention is a near-earth continuous picture taken by the camera 5 in the image capture system 1, and the motion tracking system 2 utilizes the image registration method to track and measure the motion track of the locomotive, and according to each step displacement and direction of the motion track Determine whether deviation correction is needed, and finally adjust the locomotive positioning through the control system 3 according to the offset displacement and direction to realize the locomotive positioning and deviation correction function. Wherein, the pictures taken by the camera 5 are collected by the data acquisition card 10 , and the image data is processed by the computer 11 and transmitted to the control system 3 . The pictures taken by the camera 5 are a...

Abstract

The invention relates to the moving article positioning error correcting system. The error correction system and moving tracking method for vehicle positioning comprises single chip controller controlling input and output, receiving moving parameter data required to correct, sending orders to execution mechanism, image acquiring system for acquiring continuous digital image data, running tracking system executing the running tracking algorithm based on image data execution, deciding actual running parameter, judging whether current moving status needs to be corrected and sending out the running parameters to be corrected to the control system. It starts with receiving image data, searching shared parts of two images or objects to decide the matching feature pair, calculating actual running parameter based on matching features, deciding the existing moving status of based on the relative movement of the vehicle, and deciding whether the existing running status can be recorded into the running track for continuous moving parameters.

Description

technical field [0001] The invention relates to a locomotive positioning and deviation correction system, and the invention also relates to a motion tracking method for the locomotive positioning and deviation correction system Background technique [0002] The deviation correction system is widely used in the automatic assembly line production operation and the locomotive positioning system. For example, the deviation correction control system can ensure that the materials meet the process requirements or product quality problems in the process of guiding, coiling, conveying, cutting, splicing and laminating. ; Use the correction system to realize the correct positioning of the locomotive, etc. At present, there are mainly three types of deviation correction systems: [0003] 1. Sensor correction control system: According to the sensor detecting the edge or line of the coil, read the offset between the actual position of the coil and the set position, convert the offset in...
