In order to improve the intelligent level of high-speed railway signaling specialty construction equipment and solve the problems of low efficiency,poor safety,and low accuracy in manual measurement and re-testing of trackside equipment installation,our research group developed a trackside equipment location measurement device based on the actual construction application requirements.The device adopts a RTK+photoelectric encoder positioning system,which can automatically identify the installation position of trackside equipment.After the installation of trackside equipment is completed,target recognition algorithms are used to achieve position remeasurement,and laser scanning technology is used to complete gauge data measurement.The field test results show that the device can correcdy identify trackside equipment,and all functions can operate normally.The positioning accuracy reaches millimeter level,and the measurement gauge data accuracy reaches centimeter level,which conforms to the actual application technical indicators.
