Computer vision ideas for Bangkok builders
Explore tools that help people work with photos and visual information. Each idea is tied to a local challenge and includes a practical starting point.
Food and markets
- Camera and vision
Oil Card: photograph your oil on a white card and get fry-or-change
The team prints a white card with a color strip. The owner pours a spoonful of oil on it and takes a photo; Claude vision compares the oil with the strip and says keep, watch or change, and logs the batch with the date for the day's notebook.
Build with Printed color card, Claude vision, Google Sheets
- Camera and vision
Walk Count: film a 3-minute walk past the spot, it counts rival stalls and queues
The seller films a slow walk past the intended spot at lunch. Vision counts stalls selling the same dish, how many people queue at each and how many walk by, so the market is measured before a baht is spent.
Build with Claude vision or YOLO, video frames, mobile web
- Camera and vision
Bin Cam: a camera over the bin that counts what gets thrown away
A small camera above the bin takes a photo when the lid closes. Claude vision names the items and counts them by day, so the owner sees 'croissants 6, bread 11, rice 2 kg'. The shop finds out what it overbakes and bakes less.

Small restaurants and bakeries bin good food because donating small amounts is a hassle
- Camera and vision
Fridge Cutter: photo of the fridge tells you tomorrow's fresh order
Before the evening, the owner photographs the walk-in and the prep shelf. Claude vision counts what is there and, with today's sales and a flood-day sales guess of 20 to 50%, writes the exact fresh order to send the supplier. It stops the guess-and-spoil trimming that burns cash.

Restaurants lose up to 80% of sales in a flood even when the building stays dry
- Camera and vision
Bill Card: photo of a market bill becomes a small price card for your cart
After the morning market run, the vendor photographs the receipt. Claude vision reads holy basil at 35 to 55 baht a kg and limes at 3 to 5 baht each, and prints a pocket card for the cart: 'basil up 40% since January, one plate costs 4 baht more'. Regulars read it while waiting, and the +5 baht stops feeling like a trick.

Menu Re-Pricer: photo of your paper menu becomes a delivery price sheet you print
The owner photographs the in-store menu board. Claude vision reads every dish and price, applies the app's 30% cut plus VAT, rounds to a clean 5 baht, and makes a two-column A4 sheet: in-store price, price to list on the app. Tape it next to the tablet so whoever updates the app copies the right number.

Notebook Reader: photo of the pocket notebook gives true take-home per day
Riders already jot trips and costs in a pocket notebook. Claude vision reads a photo of the page, subtracts fuel, vest rent and the bike installment, and shows what was left per day and per week, so a rider can see when a 6 baht fuel rise or a slow day pushes the month into the red.
