Solution

LiDAR solution for road vehicle camera triggering

Trigger a camera or recorder from vehicle distance change while keeping the confirmed TF application scope.

Roadside LiDAR detecting vehicles and triggering a camera

Scenario

Application scenario

This page keeps the customer-confirmed camera-trigger use case: LiDAR provides a range-change or threshold event, while the camera and traffic system handle image capture, recognition, and follow-up processing.

Engineering problem

Vehicle speed and lane position change trigger timing.
Road background, reflectivity, and weather affect returns.
Thresholds and camera latency require joint tuning.

Why LiDAR

A range event can pre-trigger a camera, reducing continuous video processing and making the trigger condition explicit.

Workflow

Define lane, detection direction, trigger distance, and camera latency.
Select a model by range, mounting height, and environment.
Connect the range event to the camera or traffic controller.
Validate different vehicle types, speeds, weather, and lane positions.

Technology comparison and selection

Dimension	Condition	LiDAR	Alternative	Alternative performance	Conclusion
Vehicle range event	The camera needs an explainable pre-trigger.	Range threshold or range-change event.	Continuous video analytics	Continuous processing with higher compute and latency.	LiDAR is suitable as a camera pre-trigger, not as image recognition. 公开来源Benewake customer application materials · Verified 2026-09-01

Selection

Product selection guide

Current material supports 2 candidates. Review product facts, rationale and boundaries together.

Model	Key product facts	Best fit and rationale	Operating boundary	Product details
TF03	Output data Single-point Distance Value Measuring range 0.1 ~ 180 m Interface UART, CAN, RS-232, RS-485 Protection IP67	TF03 is the customer-confirmed priority direction, with current long-range, IP67 and multi-interface parameters for vehicle-trigger range input on a planned detection line.	Validate vehicle material, speed, lane coverage, mounting angle, thresholds and camera-link latency on site; this does not extend to vehicle classification or 3D traffic sensing.	View product
TF02-Pro	Output data Single-point Distance Value Measuring range 0.1 ~ 40 m Interface UART, I/O, I²C Protection IP65	TF02-Pro can be a supplementary candidate when the trigger point is clearly within a 40 m-class range and a lighter IP65 single-point device is desired.	It is not the customer workbook priority model; verify road distance, interface, target and environment before retaining this alternative.	View product

Installation and integration

Rigidly mount beside or above the lane, document the detection zone, and align timing with the camera; the traffic controller owns trigger logic.

Operating limits

Do not describe range triggering as vehicle recognition or violation judgement; test vehicle types, speed, weather, and road conditions.

FAQ

Frequently asked questions

Does LiDAR identify vehicles in the road scenario?

No. LiDAR provides a range event to trigger the camera; vehicle recognition and business decisions remain with the camera and traffic system.
