IMAQ and processing unit
Technical field
The present invention relates to image processing field, more particularly to a kind of IMAQ and processing unit.
Background technology
Sled, sport on snow equipment.It is made of timber or metal.Species is various, typically whether there is rudder, has rudder, single sled, width
The type such as sled, striding type, horizontal, gang mould, traction, electronic, sail.Current Winter Olympic Games is only with without rudder sled
(also known as " motion sled " or " single sled ") and bobsled carry out contest.
It is wooden without rudder sled, bottom slide is metal.A pair of parallel slide plate is wide no more than 45cm.Slide plate fore wing is all permitted
Perhaps certain elasticity is kept, but the rudder and brake for manipulating slide plate must not be filled.Single seat is no more than 20kg again, and two-seater is no more than again
22kg.Bobsled is made of metal, and front portion is the rudder plate of a pair of work, and its top connects and equipped with fixed stream with steering wheel
Line style cover.Tail bottom is installed by brake actuator.
Bobsled 270cm long, 67cm wide, including the body weight of people are no more than 375kg.Four-man bob 380cm long, it is wide
67cm, including the body weight of people is no more than 630kg.As weight is not enough, other weighting materials can be carried give and supply.Eskimos north
Dog is typically supported by the indigenous people of polar region, for drawing sled.
Ski is common amusement all essential in northern countries red-letter day, and big people take the kids with and climb up snow mountain, from
Ice slope eminence slides down, from morning to night, untiring.The sled looked after children is usually double coaster, and child is placed on
Shovel, adult is located at sled rear end, keeps the monitoring visual field to child.
However, double coaster of the prior art is not paid close attention to due to not athletic competition project by dealer
And research and development, thus manufacturing process is low, it is impossible to meet requirement of the adult for carrying child to security performance and cornering ability.

Specific embodiment
The embodiment to IMAQ of the invention and processing unit is described in detail below with reference to accompanying drawings.
Sled originates from Switzerland mountain region, after it is gradually popular in the country such as Europe, North America and Asia.Sled is initially wooden,
After develop into and made of metal.Britain holds sled open championship first within 1884.Nineteen twenty-four is listed in first Winter Olympic Games game item
Mesh.
Generally, sled is all made by the plank of different colours, plastics or metal.Initially, slideway is also wood, used
Slideway is all aluminum, or plastic (if sled is in itself plastics).Also there is the sled on level land, they have
Backrest.Do not have backed sled all for being slided from slope high.
Currently, attempted for carrying child for the people of sled amusement, double coaster is best selection, can
Helping child to realize, that sled slides is swift as lightning, oneself can obtain satisfaction again.However, of the prior art double
Coaster is more coarse, sliding speed it is too fast, it is underload when easily cause the generation of security incident.Meanwhile,
Double coaster weight in itself is considerable plus the weight of two passengers, is lacking the situation of effective assistant equipments on board
Under, slide more difficult.
In order to overcome above-mentioned deficiency, the present invention to build a kind of IMAQ and processing unit, snow is slided by double
