Long Range Object-Level Monocular Depth Estimation for UAVs

نویسندگان

چکیده

Computer vision-based object detection is a key modality for advanced Detect-And-Avoid systems that allow autonomous flight missions of UAVs. While standard frameworks do not predict the actual depth an object, this information crucial to avoid collisions. In paper, we propose several novel extensions state-of-the-art methods monocular from images at long range. Firstly, Sigmoid and ReLU-like encodings when modeling estimation as regression task. Secondly, frame classification problem introduce Soft-Argmax function in calculation training loss. The are exemplarily applied YOLOX framework. We evaluate performance using Amazon Airborne Object Tracking dataset. addition, Fitness score new metric jointly assesses both performance. Our results show proposed outperform approaches w.r.t. existing, well metrics.

Aperture Supervision for Monocular Depth Estimation

We present a novel method to train machine learning algorithms to estimate scene depths from a single image, by using the information provided by a camera’s aperture as supervision. Prior works use a depth sensor’s outputs or images of the same scene from alternate viewpoints as supervision, while our method instead uses images from the same viewpoint taken with a varying camera aperture. To en...

Depth Estimation Using Monocular and Stereo Cues

Depth estimation in computer vision and robotics is most commonly done via stereo vision (stereopsis), in which images from two cameras are used to triangulate and estimate distances. However, there are also numerous monocular visual cues— such as texture variations and gradients, defocus, color/haze, etc.—that have heretofore been little exploited in such systems. Some of these cues apply even...

Bayesian depth estimation from monocular natural images.

Estimating an accurate and naturalistic dense depth map from a single monocular photographic image is a difficult problem. Nevertheless, human observers have little difficulty understanding the depth structure implied by photographs. Two-dimensional (2D) images of the real-world environment contain significant statistical information regarding the three-dimensional (3D) structure of the world t...

Qualitative Estimation of Depth in Monocular Vision

In this paper we propose two techniques to qualitatively estimate distance in monocular vision. Two kinds of approaches are described, the former based on texture analysis and the latter on histogram inspection. Although both the methods allow only to determine whether a point within an image is nearer or farther than another with respect to the observer, they can be usefully exploited in all t...

Monocular Vision Based Relative Depth Estimation for Hand Gesture Recognition

In this paper, we focus on real-time relative hand depth estimation with cluttered backgrounds and variable illumination for a target application to hand pushing and pulling detection. The task is characterized by a lack of consistent internal contrast in the hand combined with the complex background. We adopt a detection-and-registration strategy to predict frame-toframe scaling factor and mak...
