Apparatus and method for camera-based object distance estimation

Abstract

The present disclosure relates to an apparatus and method for estimating a distance to an object. More particularly, the apparatus includes a camera for capturing surrounding images, a LiDAR for generating a projection image by analyzing surrounding three-dimensional spatial positions, an object detection model for detecting objects in the images, a depth estimation model for estimating distances to the objects, a training unit for training the object detection model and the depth estimation model, and an estimation unit for detecting the objects in the images and estimating the distances to the objects using the object detection model and the depth estimation model. The apparatus and method may detect objects and estimate distances to the objects by using only a single camera image.
