Volumetric dimensioning with computer vision for courier and logistics
In courier operations, measurement errors cost you twice: under-declare and the carrier back-charges you; over-declare and you lose the customer on price. We built a system that estimates package dimensions with computer vision and quotes instantly against multiple carriers — each with its own volumetric factor.
Problem
Calculating volumetric weight by hand is slow and error-prone — and every carrier uses a different dimensional factor.
Result
Dimensions by computer vision and instant quotes comparing national and international carriers.
The context
Volumetric weight — the formula that turns box size into billable kilos — governs the price of every non-dense shipment. Measuring it by hand with a tape is slow, interrupts the operation, and produces errors that cost money in both directions.
To make it worse, every carrier uses its own dimensional factor and rounding rules. Comparing prices across three or four carriers for every package is work nobody does well by hand — so most operations quote with a single carrier out of inertia and leave money on the table.
How it works
The flow starts at the camera: the operator captures the package and computer vision estimates its dimensions. With the measurements and the actual weight, the rate engine applies each configured carrier’s dimensional factor and rules — national and international — and returns the price comparison instantly.
The second half of the value is integration: the result does not live in a separate app — it flows into the operation’s management system (ERP), so that quoting well does not add a step to the process; it replaces one.
Engineering decisions
Decision 01
The camera as a measuring instrument
Computer vision turns a phone or a fixed camera into a dimensioner. It does not match the precision of an industrial scanner costing thousands of dollars, but it eliminates the gross error and the friction of the manual process — which is where the money is lost.
Decision 02
A rules engine per carrier, not one formula
Every carrier has its factor, its rounding, its exceptions. We modeled the rules as per-carrier configuration instead of hard-coding them: adding a new carrier is a configuration entry, not a development project.
Decision 03
Integrated into the flow, not another screen
The quote is injected into the system the operation already uses. A tool that forces switching apps in the middle of dispatch ends up unused, no matter how good it is.
What changes for the business
The operation wins on both ends: it stops giving away kilos through bad measurement, and stops losing customers by quoting high with the wrong carrier.
- Compared quotes across carriers in seconds — no calls, no spreadsheets.
- Fewer carrier back-charges for misdeclared dimensions.
- The best available price for each package, not the default carrier’s.
- Dispatch speeds up: measuring stops being a bottleneck.

FAQ
Frequently asked questions about this case
How precise is camera-based measurement?
Precise enough to eliminate the gross error of the manual process, which is where money is lost. For loads where a centimeter changes the rate, the system lets the operator adjust the measurement before quoting — vision proposes, the operator confirms.
How many carriers can be compared?
As many as the operation needs: each carrier’s rules are configuration, not code. Adding a new one does not require a development project.
Does it integrate with our management system?
Yes — that is the design: the quote flows into your ERP or operating system via API, so the team does not switch screens in the middle of the operation.
Do I need special hardware?
Not to start: vision works with standard cameras. An industrial dimensional scanner is only justified at volumes where a centimeter is money — and the system can coexist with one.
