A lidar sensor system and method use the parallax phenomenon to determine one or more attributes of an object, such its distance, size, or shape. An optical element illuminates the object with a linear beam along a first plane. A photodetector is displaced from the optical element so that it detects the reflection of the linear beam from the object along a second plane, which is at an angle to the first plane. A computer-implemented line detection module determines a measure of deviation of the linear beam reflection from a vanishing point of the first plane. A computer-implemented analysis module determines the attribute based on the measure of deviation.

Lidar system for object detection and recognition

A computer-implemented system and method for examining the integrity of a structure having a visually repetitive pattern such as a fence, includes an imaging system having a light source and an optical element to produce a narrow substantially vertical light beam, and a photodetector to receive reflected light. The light beam is directed at the structure while moving laterally, producing a planar image of the structure which is continually refreshed. The system processes the images and identifies an anomalous feature from an anomaly in the repetitive pattern.
