Abstract

The present invention relates to method and apparatus for automatic calibration and application of optical current of monitor system, and particularly to a light projector having automatic zooming. In the invention, a driving apparatus is used to drive the light bulb through an indirect conducting stand and to make it have longitudinal movement change relative to the reflection mask position such that the projected light can reach modulation of focal length. In addition, it is possible to combine the function of a comparator and a sensor with an electronic camcorder, in which the focal length obtained from the camcorder is transmitted to the projector through the comparator and the sensor. Therefore, it is capable of reaching synchronous focus to obtain clear image.

Description

579450 5. Description of the invention (1) The light flow of the monitoring system of the present invention is particularly a light projector that can automatically adjust the light beam to obtain a bright and clear shadow system at night. In order to secretly verify the light projector, the general structure of the light projector is a hood and Mirrors, and the infrared light is emitted, which effectively achieves a secret shadow. The light type projected by the projector is therefore a fixed type. If the projected beams are fixed, if you want to retreat the projector from a long distance, The light projector, if the incident point of light is close, so that the light wave is not reflected or the opposite, the incident point is near the same can not achieve the targeted auxiliary effect of light projection, and if the same application, then you must install Waste at distance. Therefore, the present invention makes special use of the following, and drives a light flow emitted by the side bulb through the guide table to adjust the focus of the beam. Automatic adjustment application method and device, the focal length can effectively cooperate with the camera, like the ingestor 'as per usual monitoring effect' can use infrared light at night as there is no light bulb inside, and the infrared wave is connected via a reverse light wave Prove the effect of invisible wave image. The focal length of the beam is generally fixed for the target, the area is large or small, and the beam is projected. Even if the specific one is used, the other with a wide projection angle is a long-distance person. The light distance is sufficient, and clear images cannot be acquired. The distance is far away, and the light projector is a long distance. Therefore, it is impossible to produce an effective camera for most of the light projectors. The bulb that retracts to the inside of the reflector when receiving an external instruction is used behind the reflector to reach the light

For details of the present invention, please refer to the illustrations as follows. Figure 1 is a schematic diagram of the light projector structure of the present invention.

Page 4 579450 V. Description of the invention (2) Figure 2 shows the application of the light projector of the present invention. Please refer to the inner part. The lamp and motorcycle 2 1 in the inner part has a guide and the guide turns from the drive 襞 back and forth to drive the projected electric bulb 1 3. The bulb 1 2 ′ can be fitted with a facet in the shape of a bulb in the direction of 1 3. The focal length of the front and rear displacement 0 is used to achieve mobility. The first is provided with a frame attachment 2 pieces and 2 pieces 3. A conductive light bulb is connected to the slide 2, and the 2 is a set-reduced light bulb, which is driven by the source group 1 'the present invention's projection platform 1 1 and a reverse 13, the slide 2 of the seat 2 is used for a speed motor The pieces 3 2 13 and the mirror 1 5 are first attached to the body's reflection cover 1 L and the rear end forms a stage 1 1. The pieces 3 2 are obtained by the motor to obtain indirect bubbles 1 3 and the power should be obtained. The driver 3 is moved, and the 1 is for the car! The system is curved-the same as the beam i, and the light can be reached, the main shooting cover 1 2 is installed on the lamp holder 2 toward the front, the slide The 2 series of the seat 2 can be slidably placed on the lead-connecting drive member 3 2 'The drive 31 receives power, and can act as a guide for the front-back displacement by acting on the guide member 2 2, and the infrared light is converted by a flexible power cord 1 5 1 3 receives the driving device 3 indirectly via the slider 2 for the front and rear positions of the inner center line of the reflector 1 2 as a halogen bulb The inner filament 13 is placed and emits light flow in the radial direction, and the reflector 1 is displaced back and forth by the bulb 13 to interlock the filament 1 3, so that the effect of the reflector 2 can make 4 different. Change, focusing on the different changes, to provide any place with automated monitoring applications. Of course, if the present invention is only for the general

579450 5. Description of the invention (3) For applications with different focal lengths, the drive unit can be changed to manual adjustment. Please refer to FIG. 2 again, which is a schematic diagram of the application method of the light projector of the present invention, which is mainly used in conjunction with the CCD electronic camera 5 between the light projector 1 and the camera 5 via the comparator 6 and the synchronization sensor 7 Using the camera 5 as the focal distance position, the comparator 6 and a limit step sensor 7 act to drive the projector's driving device, which can be used to adjust the front and rear focal position. The current difference caused by the comparison effect of the comparator 6 is used to achieve the comparison effect of the signal, and the effect of the synchronous sensor 7 is matched to enable the projector to adjust the focal length to form an effective image acquisition for the camera 5. , And get clear images and perfect voxel effect. The above-mentioned adjustment effect of the camera 5 is another automatic control method provided by the surveillance system, and details are not described herein. According to the application effect of the projector 1 and the camera 5 of the present invention, in addition to the above, in addition to the above, an object sensor 8 can be connected to the signal, and the object sensor 8 can be used to sense a hot object or The moving object can transmit instructions to the CCD camera 5 and the light projector 1 for capturing the correct image. The induction method of the object sensor 8, that is, the aforementioned thermal temperature induction, uses an infrared induction heat wave method or a dynamic induction of a moving object, and simultaneously makes effective driving instructions for the CCD camera 5 and the projector 1. The induction method of the sensor is a general method, and it will not be described in detail anymore. The light projector of the present invention is used in addition to the optical flow application of infrared light.
