Automation storage yard laser measurement device and application method thereof

Abstract

The invention relates to an automation storage yard laser measurement device and an application method thereof. In the invention, data acquisition can be realized by using a synchronous control collector which controls a plurality of sensors, a high speed laser scanner, a horizontal displacement sensor, a horizontal rotation sensor, a vertical displacement sensor and a video sensor. The collected data is preliminarily processed by a controller. The completely ineffective data is filtered. And after GPS module time service marking is used, the data is transmitted to a background server through an integrated 3G wireless communication module. Through upper computer software, a three dimensional coordinate calculation algorithm is used to calculate a three dimensional coordinate. A three dimensional modeling algorithm is used to carry out modeling. And then a material volume to be measured can be calculated. For a problem that working time sequences of the sensors are inconsistent, an annular buffer area technology is used to realize asynchronous data acquisition and storage. A dynamic interconnection problem of the 3G router equipment can be solved. A feasible scheme is provided for remote wireless control and implementation costs can be saved.

Description

technical field [0001] The invention relates to a laser measuring device and its usage method, in particular to an automatic stockyard laser measurement device and its usage method. Background technique [0002] There are generally several methods for large-scale stockyard inventory: (1) Obtaining three-dimensional coordinates based on the manual measurement point of the distance measuring instrument. This method requires manual shaping before measurement, which has a long cycle, low precision, and large human factors. (2) Based on uniform motion, Calculate the moving distance based on the time average, combined with the scanner section to calculate the three-dimensional coordinate method, this method simply assumes that the measurement carrier moves at a uniform speed, and the measurement equipment does not produce any angle and speed changes during the measurement process, which is difficult to meet the requirements in actual measurement. (3) Based on Multi-sensor integrat...

AI Technical Summary

Problems solved by technology

[0003] On the basis of the existing inventory measurement system, the following problems need to be solved for the inventory measurement of large-scale stockyards: (1) The inventory measurement of large-scale stockyards relies on mobile measurement carriers. In order to achieve the purpose of remote control, a communication environment needs to be established

Usually, the IP address of the device to be connected can be obtained manually by applying for a fixed IP or each time it is used, and then written to the device in use, resulting in complicated use or increased cost

(2) The original stockyard inventory measurement system only considered scanners, horizontal displacement sensors, and horizontal rotation sensors, but did not consider vertical displacement and video transmission sensors

(5) There is no unified material yard coordinate system and any formula for calculating the three-dimensional coordinates of the material yard
