Description
Technical field
The utility model is related to image calibration field more particularly to a kind of light source of calibration.
Background technology
It has been difficult the needs for meeting people that a camera is integrated on smart machine, and different work(are carried out by multiple cameras
Energy combination, the multi-cam module that can complete complex task, certainly will appear on more and more smart machines.Multi-cam mould
Group is cooperated by multiple cameras, is synthesized by the image obtained to different cameras to realize specific function,
It is high to the coherence request of each camera, therefore before manufacture need that each camera is carried out to calibrate raising consistency.
Due to having multiple cameras in multi-cam module, and the quantity of camera, size and spacing etc. all differ
Sample, which results in the multi-cam modules of different size to need to customize calibrating the light source used when burning, can not share；Light
The size in source is bigger, and cost is also higher；As long as one of LED light is broken, entire light source cannot use.These are resulted in
The production cost of multi-cam module is higher.In addition, the stability and uniformity at the center of light source all than surrounding than get well, light
The center in source can not cover all cameras of multi-cam module, and calibration accuracy is impacted.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of light for the calibration of multi-cam module
Source device can make the cost that multi-cam module is calibrated be lower, operability becomes strong, light source utilization rate becomes high.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of light source for the calibration of multi-cam module, including light supply apparatus, the light supply apparatus can including one
Mobile light source makes each camera in the multi-cam module respectively under the light source by the movement light source
Carry out calibration burning.
Further, further include carrying out mobile mobile device, the light source for controlling the light source of the light supply apparatus
Setting is on the mobile device.
Further, the mobile device is electrically connected to calibrating installation, described more for being obtained out of described calibrating installation
The calibration procedure of camera module, and the light source is automatically controlled according to calibration procedure and is moved.
Further, the mobile device includes middle control module and mobile mechanism, wherein：
The middle control module is connected to calibrating installation, the calibration procedure for obtaining the multi-cam module, and according to
Calibration procedure sends out control instruction to the mobile mechanism；
The mobile mechanism is connected to the middle control module, for driving the light source to be moved according to control instruction；
The light source is arranged in mobile mechanism.
Further, the mobile mechanism is mechanical arm, three axis mobile mechanisms or sliding rail mobile mechanism.
The utility model has the advantages that：The light source has a moveable light source, is carrying out more camera shootings
When the calibration of head mould group, by way of the movement light source, each camera of the respectively described multi-cam module provides
Light is calibrated, the size of the light source is not influenced by camera quantity, size and the spacing etc. of the multi-cam module, is led to
For the multi-cam module of various different sizes, therefore, the utilization rate of the light source is high；The size of the light source can be made
It is smaller, production cost is reduced, moreover, each camera can carry out school on the center corresponding to the light source
Standard, calibration accuracy is higher, and consistency is also high.
Description of the drawings
Fig. 1 is the functional block diagram of light source provided by the utility model.
Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of light source calibrated for multi-cam module 1, including light supply apparatus, the light source dress
It sets including a moveable light source, so that each camera in the multi-cam module 1 is distinguished by the movement light source
Calibration burning is carried out under the light source.
Multi-cam module 1 includes at least two cameras, and in the present embodiment, the multi-cam module 1 includes three
Camera, respectively the first camera, second camera and third camera.
The light source moves the light source first in the calibration process of multi-cam module 1, and the light source is made to be located at
First camera is calibrated in the top of first camera；Then the light source is moved again, and the light source is made to be located at the
The second camera is calibrated in the top of two cameras；The light source is finally moved again, and the light source is made to be located at third
The third camera is calibrated in the top of camera.Optimally, position of each camera when being calibrated is right
The center of light source described in Ying Yu.
The light source has a moveable light source, when carrying out the calibration of multi-cam module 1, described in movement
The mode of light source, respectively each camera of the multi-cam module 1 provide calibration light, the size of the light source not by
The influence of camera quantity, size and the spacing of the multi-cam module 1 etc., is common to the multi-cam of various different sizes
Module 1, therefore, the utilization rate of the light source are high；The size of the light source can be made smaller（Generally 30*30mm）, drop
Low production cost, moreover, each camera can be calibrated on the center corresponding to the light source, calibration essence
Degree is higher, and consistency is also high；The cost replaced after the light source damage is relatively low.
When being calibrated, the movement of the light source is manually controllable, also can be automatically controled.When manually controlling, people is detected
Member adjusts the position of the light source according to calibration procedure manually, and when automatically controlling, which adjusts automatically according to calibration procedure
Save the position of the light source.
Preferably, the light source is mobile using automatically controlling, i.e., the light source further includes for controlling the light source
