Distance presets far and near each piecemeal that the Ha Er filter apparatus is averagely divided into relevant block size of resolution threshold, to every
One piecemeal, the pixel value variance based on the piecemeal select the normalization of corresponding varying strength to adjust processing to obtain correction point
Block splices each correction piecemeal of acquisition to obtain adjustment image in real time；Using luminous point detection device, adjusted with the normalization
Finishing equipment connects, for receiving the real-time adjustment image, from based on default luminous point gray threshold range from the real-time adjustment
Multiple luminous point subgraphs are identified and be partitioned into image, calculate the area of each luminous point subgraph, and in the multiple luminous point
When the percentage that the gross area of subgraph occupies the area of the real-time adjustment image is more than or equal to preset percentage threshold value, send out
The bad signal of quality；In the camera imaging management method based on luminous point detection：The luminous point detection device is additionally operable in institute
The percentage for the area that the gross area for stating multiple luminous point subgraphs occupies the real-time adjustment image is less than the preset percentage
When threshold value, up-to-standard signal is sent out；In addition, alternatively, ultrasonic ranging equipment can be used and replace the infrared distance measurement equipment；
Ultrasonic ranging principle is as follows：Ultrasonic transmitter emits ultrasonic wave to a direction, starts timing while emission time,
Ultrasonic wave is propagated in air, is encountered barrier on the way and just is returned to come immediately, ultrasonic receiver receives back wave and just stops immediately
Only timing；The aerial spread speed of ultrasonic wave is 340m/s, according to the time t of timer record, so that it may be set out with calculating
Distance (s) of the exit point away from barrier, i.e.,：S=340t/2；Here it is so-called time difference telemetrys；The principle of ultrasonic ranging
To be using the aerial spread speed of ultrasonic wave be it is known that measure sound wave encountered after transmitting barrier it is reflected when
Between, according to transmitting and receive time difference calculate launch point to barrier actual range；It can be seen that ultrasonic ranging is former
Reason and Principles of Radar are the same；
However, in fact, the aerial spread speed of ultrasonic wave is a variable, according to the difference of ambient temperature, surpass
The aerial spread speed of sound wave is also different, therefore, in order to improve the accuracy of ultrasonic ranging, it is necessary first to according to surrounding
Environment temperature calculates the aerial spread speed of ultrasonic wave；Camera imaging management system using the present invention based on luminous point detection
System and method customize the technical issues of occasion is difficult to accurate judgement, by introducing for camera imaging quality in the prior art
Luminous point detection device is identified and is partitioned into from described image from based on default luminous point gray threshold range for receiving image
Multiple luminous point subgraphs calculate the area of each luminous point subgraph, and are occupied in the gross area of the multiple luminous point subgraph
It is excessive to avoid occurring in camera imaging image when the percentage of the area of described image is more than or equal to preset percentage threshold value
Luminous point, it is even more important that also introduce multiple targetedly image-preprocessing devices and cooperate, improve image
The speed and precision of pretreatment mechanism.
