The object of the present invention is achieved like this: shone by the many groups of infrared launcher groups that are installed on around the motor vehicle all around, every group comprises at least 1 infrared launcher, real continuous wide dynamic range camera system during by the many groups of infrared low-light (level)s that are installed on around the motor vehicle all around, to the target (pedestrian around the motor vehicle, vehicle or barrier) carry out shooting, collecting, each direction is installed 1 group at least, every group of wide dynamic range camera system real continuous when comprising 2 infrared low-light (level)s, the sensitive chip of real continuous wide dynamic range camera system is all hidden by light filter during the 1st infrared low-light (level) during its every group infrared low-light (level) in the real continuous wide dynamic range camera system, camera system is charge-coupled device (CCD) video camera or complementary metal oxide semiconductor (CMOS) (CMOS) video camera, and synchronizing signal produces and controller, the 1st storer, the 1st central processing unit, buzzer siren, the 2nd storer, the 2nd central processing unit, illustration is with reference to portion, image switching apparatus, display device, impact microphone, image cycle index device, satellite positioning device, media playing apparatus is formed, synchronizing signal produces and controller real continuous wide dynamic range camera system during the infrared low-light (level) of 2 in the real continuous wide dynamic range camera system when connecting the infrared low-light (level) of many groups respectively, real continuous wide dynamic range camera system connects the 1st storer respectively during the infrared low-light (level) of during the infrared low-light (level) of many groups in the real continuous wide dynamic range camera system 2, the 2nd storer, the 1st storer connects the 1st central processing unit, the 2nd storer connects the 2nd central processing unit, the 1st central processing unit connects buzzer siren respectively, image cycle index device, image switching apparatus, the 2nd central processing unit connects illustration respectively with reference to portion, image cycle index device, image switching apparatus, impact microphone connects with image cycle index device, satellite positioning device, media playing apparatus connects with image switching apparatus, and image switching apparatus connects with display device.
This field of wide dynamic range video camera has obtained deep research in recent years, and the solution that enlarges the video camera dynamic range can be divided into following three classes:
A, compression response characteristic curve
With a sensor compression response characteristic curve with logarithmic response.
It is realized by two methods:
First method is that it is worked with a momentary current readout mode with a cmos sensor.Under this pattern, the photocurrent that photo-detector produces is had by one of feed-in in the device of logarithmic response with the compression sensor transformation curve, and this device is such as the diode that is a connection MOS transistor, and this configuration can realize very wide dynamic range.
The second method of compression induction curve is the technology of regulating with reference to well capacity (well capacity) with a kind of.Here, increase well capacity (well capacity) by one or many in the time shutter and increase dynamic range.Well capacity between integration period (well capacity) is increased to its maximal value monotonously.Unnecessary photogenerated charge is discharged by an overflow gate.
B, repeatedly sampling
In repeatedly taking a sample, scenery repeatedly and with data combines wide dynamic range image of formation in difference exposure imaging in period.Reasonably catching the method for working under the number of times for this, readout must be finished under than the much higher speed of common movable pixel sensor (APS).This repeatedly sampling plan has realized wide dynamic range effectively.
C, control integral time
Controlling integral time is to compare the third method that additive method has more some promising characteristics.Substantially, the time shutter of each pixel is adjusted separately so that they can be unsaturated when each integration period finishes.There are many approach to realize this method.
Three above-mentioned class solutions have been made number of research projects both at home and abroad to this, comparative maturity, and practical effect is also relatively good, can satisfy the infrared low-light (level) wide dynamic range camera system needs in the motor vehicle day and night running observing recorder.
The three-dimensional information of space object was obtained in real continuous wide dynamic range camera system imaging simultaneously when the present invention adopted 2 every group infrared low-light (level)s, its principle of work is: a certain spatial point about when the projection on real continuous wide dynamic range camera system plane is respectively with corresponding infrared low-light (level) during 2 infrared low-light (level)s the on line of real continuous wide dynamic range camera system photocentre must intersect at unique point in the space, promptly above-mentioned spatial point.The coordinate difference (parallax) of our real continuous wide dynamic range camera system correspondence image plane corresponding point when obtaining 2 infrared low-light (level)s, the three dimensions that the continuous wide dynamic range camera system calibration technique of reality both can have been recovered spatial point when distance (base length) during by 2 infrared low-light (level)s between the real continuous wide dynamic range camera system and infrared low-light (level) is represented.Real continuous wide dynamic range camera system is taken pictures simultaneously to object scene or target when utilizing the infrared low-light (level) in the left and right sides in actual process, obtain two width of cloth pictures of same object different angles, realize the coupling of corresponding point in the image of the left and right sides by central processing unit, according to the coordinate difference (parallax) of corresponding diagram picture point in the respective image coordinate system, obtain the disparity map of space object, the space three-dimensional information playback of real continuous wide dynamic range camera system calibration technique during then according to infrared low-light (level) (real continuous wide dynamic range camera system image coordinate is tied to the mapping techniques between the space coordinates during from infrared low-light (level)) and three-dimensional reconstruction technique realization scene objects (space object that has lap two width of cloth images) obtains the most complete three-dimensional image information thus.
In recent years, the dual vision technical field has obtained deep research, and application has widely been arranged.For example pass through two eyes of simulation, and utilize the correlation calculations depth information of the left and right view lap that is taken, finally determine the azimuth information of attention object.Its major technique comprises two aspects, and one is the space geometry relation between definite left and right view, and another one is exactly to seek the problem of pixel of the same name on left and right view.This has been made number of research projects both at home and abroad, the algorithm comparative maturity, practical effect is also relatively good, the needs of the two-way localization process system of real continuous wide dynamic range camera system in the time of can satisfying based on infrared low-light (level).
When real continuous images with super-wide dynamic range is rebuild when infrared low-light (level), be by the position of every group 2 width of cloth image is proofreaied and correct, merged, during infrared low-light (level) the reconstruction of real continuous images with super-wide dynamic range can adopt simply average, weighted value, surface fitting interpolation etc., can also be by earlier the response curve of image Sensitive Apparatus being demarcated, real continuous images with super-wide dynamic range when then with every group 2 width of cloth image co-registration together, forming 1 infrared low-light (level) based on response curve.
