Abstract
There is provided a system for detecting an object crossing a plane at high resolution from long range, the system including a first transmitter projecting a light plane using a light comprising a light plane wavelength, the light plane defining a boundary, wherein the light plane wavelength is not visible to the human eye, a first receiver for detecting a reflection of light when an object crosses the light plane defining the boundary, the receiver configured to detect light in a range of the electromagnetic spectrum including the light plane wavelength, wherein the receiver includes an image sensor comprising a plurality of sensor pixels, and an image processing computer configured to receive an input from the receiver including a recorded frame captured by the receiver, wherein the image processing computer processes the recorded frame for review to identify a frame showing an object crossing the boundary.
