logiVDET is a learning-based vehicle detection IP core, developed for embedded vision applications. The algorithm follows a discriminative approach based on a cascaded classifier using Local Binary Pattern features.
In order to detect vehicles in an arbitrary range, the core accepts in input a pyramid of images.
Detection results are stored into an internal buffer, ready for the host controller read-out.

Core structure

A detection window slides the input image. For each window position the LBP signature is computed and classified to establish if it is the target object or not.

Post-processing and distance estimation

The core is provided with drivers and an embedded software library in C code implementing post-processing functions necessary to group together overlapping detections, track the objects and compute their distance from the camera. The detection range depends on the imager and camera lens: with 1Mp @30fps camera, detection approximately covers a range of 1-100m using 50º FOV lens.
