Abstract: PURPOSE: A target distance measurement system using a scanning driving infrared light sensor device is provided to reduce risk of exposure by making the device hard to find from the outside. CONSTITUTION: A target distance measurement system consists of a scanning driving infrared light sensor device(10) and an image processing device(20). The scanning driving infrared light sensor device consists of a scanning mirror(12) and an infrared light sensor(14). The scanning mirror is disposed in the front side and receives infrared from the detected region including the target by repetitively rotating in a predetermined driving period and angle range. The infrared light sensor obtains a first scanning image and a second scanning image of the target by incident infrared light in one rotation position and another rotation position. If an image corresponding to the target exists in the overlapped part of the first scanning image and the second scanning image, the image processing device calculates 3-D distance information of the target by analyzing a correlation of the first scanning image and the second scanning image.

The target tracking method includes: a step of predicting the location of a target; a step of tracking the target by connecting each target signal, which is inputted every hour from a sensor unit which senses the target, to a component using the predicted location of the target; a step of, while the target is being tracked, calculating a track score to evaluate the tracking performance of a track as a probability index to measure the reliability of an ongoing track based on a Markov chain model in which a hypothesis about the existence of a target signal and a hypothesis about a blind situation are applied and updating data about the target to target the target using the Markov chain model; a step of merging or removing a component of the track using the Markov chain model; and a step of removing the track if the calculated track score is smaller than a predefined threshold value or confirming and maintaining the track if the score is equal to or greater than the predefined threshold value. By doing so, the present invention is able to track a target even after the target gets out of a blind environment, thereby improving solidity in tracking a target.
