$50 Aerial Digital Photography from a Balloon

jizmonkey writes "This guy built a balloon to take digital aerial photographs from thousands of feet up. It cost less than $50 altogether, including the image sensor, controller, and balloon. The circuit is surprisingly straightforward: just a hacked Vivitar minicamera, a 555 timer chip driving a relay through a voltage regulator, and a one-meter party balloon like the ones you see at used car dealerships. It just so happens that the entire circuit, strapped to a piece of a pizza box and tied to a really long string, is light enough to be lifted by the balloon. What could low-cost aerial photography be used for? I'm sure some people have some ideas...."

    Colonel Harland Sanders, born September 9, 1890, actively began franchising his
    chicken business at the age of 65. Now, the Kentucky Fried Chicken® business he started
    has grown to be one of the largest retail food service systems in the world. And Colonel
    Sanders, a quick service restaurant pioneer, has become a symbol of entrepreneurial spirit.
    More than two billion of the Colonel's "finger lickin' good" chicken dinners are served
    annually. And not just in North America. The Colonel's cooking is available in more than
    82 countries around the world. When the Colonel was six, his father died. His mother was
    forced to go to work, and young. Harland had to take care of his threeyearold brother
    and baby sister. This meant doing much of the family cooking. By the age of seven, he was
    a master of a score of regional dishes. At age 10, he got his first job working on a nearby
    farm for $2 a month. When he was 12, his mother remarried and he left his home near
    Henryville, Ind., for a job on a farm in Greenwood, Ind. He held a series of jobs over the
    next few years, first as a 15yearold streetcar conductor in New Albany, Ind., and then as
    a 16yearold private, soldiering for six months in Cuba.
    After that he was a railroad fireman, studied law by correspondence, practiced in justice
    of the peace courts, sold insurance, operated an Ohio River steamboat ferry, sold tires, and
    operated service stations. When he was 40, the Colonel began cooking for hungry travelers
    who stopped at his service station in Corbin, Ky. He didn't have a restaurant then, but
    served folks on his own dining table in the living quarters of his service station. As more
    people started coming just for food, he moved across the street to a motel and restaurant
    that seated 142 people. Over the next nine years, he perfected his secret blend of
    11 herbs and spices and the basic cooking technique that is still used today. As we grew...
    Sander's fame grew. Governor Ruby Laffoon made him a Kentucky Colonel in 1935 in
    recognition of his contributions to the state's cuisine. And in 1939, his establishment was
    first listed in Duncan Hines' "Adventures in Good Eating." In the early 1950s a new
    interstate highway was planned to bypass the town of Corbin. Seeing an end to his
    business, the Colonel auctioned off his operations. After paying his bills, he was
    reduced to living on his $105 Social Security checks.
    Confident of the quality of his fried chicken, the Colonel devoted himself to the chicken
    franchising business that he started in 1952. He traveled across thecountry by car from
    restaurant to restaurant, cooking batches of chicken for restaurant owners and their
    employees. If the reaction was favorable, he entered into a handshake agreement on a deal
    that stipulated a payment to him of a nickel for each chicken the restaurant sold. By 1964,
    Colonel Sanders had more than 600 franchised outlets for his chicken in the United States
    and Canada. That year, he sold his interest in the U.S. company for $2 million to a group of
    investors including John Y. Brown Jr., who later was governor of Kentucky from 1980 to
    1984. The Colonel remained a public spokesman for the company. In 1976, an independent
    survey ranked the Colonel as the world's second most recognizable celebrity. Under the
    new owners, Kentucky Fried Chicken Corporation grew rapidly. It went public on March 17, 1966, and was listed on the New York Stock Exchange on January 16, 1969. More than
    3,500 franchised and companyowned restaurants were in worldwide operation when
    Heublein Inc. acquired KFC Corporation on July 8, 1971, for $285 million.
    Kentucky Fried Chicken became a subsidiary of R.J. Reynolds Industries, Inc. (now
    RJRNabisco, Inc.), when Heublein Inc. was acquired by Reynolds in 1982. KFC was
    acquired in October 1986 from RJR Nabisco, Inc. by PepsiCo, Inc., for approximately
    $840 million. Colonel Sanders was always experimenting with food at his restaurant in
    Corbin, Ky.,

    The most important aid to recognising a vehicle as it moves about a network is its number plate, and to see that the camera has to be viewing an oblique or horizontal plane. The Hanshin Expressway network (Osaka, Japan) has video cameras all over the place. They track numberplates through the network to calculate journey times to various destinations which are then displayed on information boards and relayed via highway radio to car GPS systems that are designed to accept that information. At accident black spots, cameras use motion analysis to detect accidents in progress. (At tollbooths, cameras identify the location of the driver's head to decide from which of a column of vertical slots the ticket should be dispensed, to be within easiest reach)

    I expect other networks do something similar with video networks.

    In your situation, you could probably get better analysis data from a few static video cameras coupled with some image processing: you don't need to know exactly where every vehicle is all the time to carry out congestion analysis, for example. Since you mention "heavy traffic", the video data may already be available on tape, since you don't need to do this in real time, I assume.
