Python Branch: master. Find file.The object detection and object orientation estimation benchmark consists of training images and test images, comprising a total of All images are color and saved as png. For evaluation, we compute precision-recall curves for object detection and orientation-similarity-recall curves for joint object detection and orientation estimation. In the latter case not only the object 2D bounding box has to be located correctly, but also the orientation estimate in bird's eye view is evaluated.

To rank the methods we compute average precision and average orientation similiarity. We require that all methods use the same parameter set for all test pairs.

Detections in don't care areas or detections which are smaller than the minimum size do not count as false positive. Difficulties are defined as follows:. All methods are ranked based on the moderately difficult results. Hence, the hard evaluation is only given for reference. Note 1: On As of now, the submitted detections are filtered based on the min.

Reliable and accurate 3D object detection is a necessity for safe autonomous driving.

Although LiDAR sensors can provide accurate 3D point cloud estimates of the environment, they are also prohibitively expensive for many settings. PL combines state-of-the-art deep neural networks for 3D depth estimation with those for 3D object detection by converting 2D depth map outputs to 3D point cloud inputs. However, so far these two networks have to be trained separately.

In this paper, we introduce a new framework based on differentiable Change of Representation CoR modules that allow the entire PL pipeline to be trained end-to-end. The resulting framework is compatible with most state-of-the-art networks for both tasks and in combination with PointRCNN improves over PL consistently across all benchmarks — yielding the highest entry on the KITTI image-based 3D object detection leaderboard at the time of submission.

One of the most critical components in autonomous driving is 3D object detection: a self-driving car must accurately detect and localize objects such as cars and pedestrians in order to plan the path safely and avoid collisions. To this end, existing algorithms primarily rely on LiDAR Light Detection and Ranging as the input signal, which provides precise 3D point clouds of the surrounding environment.

LiDAR, however, is very expensive. A beam model can easily cost more than the car alone, making self-driving cars prohibitively expensive for the general public.

One solution is to explore alternative sensors like commodity stereo cameras. While the modularity of pseudo-LiDAR is conceptual appealing, the combination of two independently trained components can yield an undesired performance hit.

In particular, pseudo-LiDAR requires two systems: a depth estimator, typically trained on a generic depth estimation stereo image corpus, and an object detector trained on the point cloud data converted from the resulting depth estimates.

It is unlikely that the two training objectives are optimally aligned for the ultimate goal, to maximize final detection accuracy.

For example, depth estimators are typically trained with a loss that penalizes errors across all pixels equally, instead of focusing on objects of interest. Consequently, it may over-emphasize nearby or non-object pixels as they are over-represented in the data. To address these issues, we propose to design a 3D object detection framework that is trained end-to-endwhile preserving the modularity and compatibility of pseudo-LiDAR with newly developed depth estimation and object detection algorithms.

To enable back-propagation based end-to-end training on the final loss, the change of representation CoR between the depth estimator and the object detector must be differentiable with respect to the estimated depth.

We focus on two types of CoR modules — subsampling and quantization — which are compatible with different LiDAR-based object detector types. We study in detail on how to enable effective back-propagation with each module. Specifically, for quantization, we introduce a novel differentiable soft quantization CoR module to overcome its inherent non-differentiability.

The resulting framework is readily compatible with most existing and hopefully future LiDAR-based detectors and 3D depth estimators. Different from previous image-based 3D object detection models, pseudo-LiDAR first utilizes an image-based depth estimation model to obtain predicted depth Z uv of each image pixel uv. Our work builds upon this framework. However, it also lacks the notion of end-to-end training of both components to ultimately maximize the detection accuracy.

In particular, the pseudo-LiDAR pipeline is trained in two steps, with different objectives. First, a depth estimator is learned to estimate generic depths for all pixels in a stereo image; then a LiDAR-based detector is trained to predict object bounding boxes from depth estimates, generated by the frozen depth network.

On one end, a LiDAR-based object detector heavily relies on accurate 3D points on or in the proximity of the object surfaces to detect and localize objects. Especially, for far-away objects that are rendered by relatively few points.

On the other end, a depth estimator learned to predict all the pixel depths may place over-emphasis on the background and nearby objects since they occupy most of the pixels in an image. Such a misalignment is aggravated with fixing the depth estimator in training the object detector: the object detector is unaware of the intrinsic depth error in the input and thus can hardly detect the far-away objects correctly. To enable back-propagating the error signal from the final detection loss, the change of representation CoR between the depth estimator and the object detector must be differentiable with respect to the estimated depth.

The 3D point locations are discretized into a fixed grid, and only the occupation i.The 3D object detection benchmark consists of training images and test images as well as the corresponding point clouds, comprising a total of For evaluation, we compute precision-recall curves. To rank the methods we compute average precision. We require that all methods use the same parameter set for all test pairs.

Far objects are thus filtered based on their bounding box height in the image plane. As only objects also appearing on the image plane are labeled, objects in don't car areas do not count as false positives.

We note that the evaluation does not take care of ignoring detections that are not visible on the image plane — these detections might give rise to false positives. Difficulties are defined as follows:.

Minor modifications of existing algorithms or student research projects are not allowed. Such work must be evaluated on a split of the training set. To ensure that our policy is adopted, new users must detail their status, describe their work and specify the targeted venue during registration. Furthermore, we will regularly delete all entries that are 6 months old but are still anonymous or do not have a paper associated with them.

For conferences, 6 month is enough to determine if a paper has been accepted and to add the bibliography information. For longer review cycles, you need to resubmit your results.

Depending on your setup, training should take approximately 16 hours with a Titan Xp, and 20 hours with a GTX If the process was interrupted, training or evaluation will continue from the last saved checkpoint if it exists. The evaluator has two main modes, you can either evaluate a single checkpoint, a list of indices of checkpoints, or repeatedly.

Reload to refresh your session.We take advantage of our autonomous driving platform Annieway to develop novel challenging real-world computer vision benchmarks. Our tasks of interest are: stereo, optical flow, visual odometry, 3D object detection and 3D tracking.

For this purpose, we equipped a standard station wagon with two high-resolution color and grayscale video cameras. Accurate ground truth is provided by a Velodyne laser scanner and a GPS localization system.

Our datsets are captured by driving around the mid-size city of Karlsruhein rural areas and on highways. Up to 15 cars and 30 pedestrians are visible per image. Besides providing all data in raw format, we extract benchmarks for each task. For each of our benchmarks, we also provide an evaluation metric and this evaluation website. Preliminary experiments show that methods ranking high on established benchmarks such as Middlebury perform below average when being moved outside the laboratory to the real world.

Our goal is to reduce this bias and complement existing benchmarks by providing real-world benchmarks with novel difficulties to the community.
