We present a novel and high-performance framework for 3D object detection using stereo vision. This framework incorporates direct instance depth estimation efficiently, improving the accuracy of the final 3D object detection. Instead of detecting objects separately in the left and right images of a stereo display, we exploit a modified 2D object detector that takes only the left image as input to generate union 2D bounding boxes for both images, and to predict the depth of the 3D box center for each object. Using the union 2D boxes, we propose a direct instance-level depth estimation network, taking the estimated depth as guidance, to predict the desired depths for pixels belonging to an object from a small search range. This approach greatly improves the efficiency and accuracy of 3D detection. Moreover, we design an adaptive spatial feature aggregation module that can weaken the effect of background points and automatically integrate important instance features to achieve accurate 3D object localization. Our method outperforms current state-of-the-art stereo-based 3D detection methods on the KITTI benchmark dataset, and it can efficiently employ a shared model for 3D multi-class detection.
