Description
Technical Field
[0001] The present invention relates to the technical field of image collectors, and in particular to an image collection device based on an image sensor. Background Art
[0002] An image sensor utilizes the photoelectric conversion function of a photoelectric device to convert the light image on its photosensitive surface into an electrical signal that is proportional to the light image. Compared with photosensitive elements with "point" light sources such as photodiodes and phototransistors, an image sensor is a functional device that divides the light image on its light-receiving surface into many small units and converts them into usable electrical signals. An image acquisition device is a device that uses an image sensor to convert an optical image into an electronic signal.
[0003] At present, when image acquisition devices are working under high loads such as high resolution, high frame rate, long exposure or low light, the image sensor generates a lot of heat due to electrical loss and optical absorption. The continuous accumulation of heat may cause structural parts such as the lens mount and housing to deform due to thermal expansion, resulting in the relative position of the lens and sensor to shift, causing image blur or edge distortion. At the same time, when the temperature is high, the response curves and noise levels of pixels in different areas will differ, which will manifest as local brightness or color deviation of the image, affecting the normal use of the image acquisition device.

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. The present invention sets a heat dissipation component. The image collector body contains a large number of image sensors. When the image collector works for a long time, the heat generated by the electronic components inside it may accumulate. The circulation pump is started to extract the coolant inside the liquid storage box and then transport it through the liquid outlet pipe. The coolant enters the interior of the liquid cooling plate through the liquid outlet pipe, thereby allowing the coolant to continuously flow inside the liquid cooling plate. At the same time, a plurality of microporous channels are opened inside the liquid cooling plate to allow the coolant to flow inside it. At the same time, under the action of the heat conducting plate, the heat emitted by the image collector body is dissipated. Absorption and transmission, the heat is transmitted to the liquid cooling plate through the heat-conducting copper tube, and then the heat is absorbed by the coolant. The coolant that has absorbed the heat can enter the interior of the liquid storage box through the liquid outlet pipe. At the same time, the coolant with higher temperature is inside the liquid storage box, and the cold end of the semiconductor refrigeration plate is in contact with one side of the liquid storage box, thereby absorbing the temperature of the coolant with higher temperature inside the liquid storage box. The heat is transferred and dissipated to the surrounding environment through the heat dissipation plate, so that the temperature of the coolant can be kept stable, so that the coolant can circulate continuously, so that the liquid cooling plate can continuously absorb and dissipate the heat generated by the image acquisition body;
[0019] 2. By providing a fixed plate and a sliding bar, when adjusting the image acquisition position of the image collector body, the staff can activate the cylinder. Under the action of the cylinder, the sliding bar can be driven to move inside the fixed plate, thereby enabling the sliding bar to drive the image collector body to move to the specified position. At the same time, the staff can position the sliding bar and the fixed plate through the positioning bolts and positioning holes to prevent the sliding bar from being deformed to a certain extent due to the heavy gravity it bears, thereby ensuring that the fixed plate and the sliding bar can be stably placed.
[0020] 3. By setting the first gear and the second gear, starting the motor, the motor can drive the transmission rod to rotate, and then when the transmission rod rotates, it can drive the first gear to rotate. The first gear and the second gear have different sizes, and the staff can adjust the speed of the second gear by controlling the speed of the motor, so that the rotation speed of the image collector body can be adjusted, and the image collector body can be slowly rotated to collect images of the surroundings.
