(3) Technical solutions and their advantages and characteristics

Chengdu, a fourth-tier city: It takes the lead in demonstrating and applying the Intelligent Train Eagle Eye System (ITE) in southwest China and promoting its engineering implementation.

ITE collects information data of the line ahead of the train's progress through sensor devices such as radars and cameras. By using real-time positioning, map construction technology, sensor fusion technology, etc., it realizes the functions of precise train positioning and obstacle detection, reaches the SIL4 safety level, and further enhances the safety protection of train operation.

? Innovatively develop an orbital target detection technology that integrates machine vision and radar, achieve obstacle trajectory tracking, and improve detection accuracy, reliability, and scene adaptability.

? Develop environmental perception technologies for fully automatic train operation, improve the recognition rate, reduce the false alarm rate, and propose functional design plans for multiple scenarios such as fault emergencies.

? Develop a multi-modal fusion train autonomous positioning technology that integrates data from images, radars, etc., to achieve accurate positioning initialization and precise measurement of speed and pose.
