LiDAR Coverage Simulation: Finding Blind Spots Before You Install
2026-10-05 · data as of 2026-10-12
Combine mounting height and angle, vertical and horizontal field of view, occlusion by structures, and the stopping distance of the vehicle in a virtual environment first. That lets you fix the number and placement of sensors before touching the site.
Have you ever finished an installation and only then noticed a blank patch on the screen? I have. It cost two extra sensors, and the budget and schedule moved with them.
That taught me one thing: coverage should be worked out on paper first, not discovered on site. These days a simulator does most of that work.
A datasheet range is not a promise
A number like "detection range 100 m" on a spec sheet is a maximum under specific conditions. How brightly the target reflects, at what angle the beam strikes it, and whether there is dust or fog in the air all shift the real detection range considerably.
Safety-device standards make the gap explicit. Safety laser scanners typically have a protective field of about 3–9 m but a warning field of 20–40 m. The distance at which you can reliably stop a person and the distance at which you can warn them are simply different numbers.
Blind spots are caught with arithmetic
Blind spots usually come from three places: the cone directly beneath the sensor, the shadow cast by a pillar or rack, and anything outside the field of view. Lower the mount and you see the floor but not far; raise it and the reverse happens.
Then add stopping distance. If equipment moves at 2 m/s and total response from detection to stop is 0.3 seconds, it travels another 0.6 m before the brake really bites. Miss that and no amount of coverage keeps you safe.
Comparing height, angle and field of view side by side in a simulator turns "how many, and where" into numbers. Being able to test several options before installation is the real payoff.
One myth: more sensors always fix it
When coverage is short, adding sensors feels natural. Yet one well-angled unit often beats two badly angled ones. Adjusting the layout before increasing the count is cheaper and easier to maintain.
Good coverage comes from layout, not quantity. Comparing options in a simulation before installation cuts rework and extra spend on site.
If your current plan is "install and add more later," consider flipping that order just once.
